Answer:
Without more information about the specific survey and population being surveyed, it is difficult to provide a precise answer to this question. However, I can provide some general information on how probabilities can be calculated in surveys.
Assuming that the survey is a representative sample of college students and that the question about difficulty falling asleep is a binary (yes/no) question, we can calculate the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week as follows:
1. Determine the total number of surveyed college students who answered the question about difficulty falling asleep.
2. Determine the number of surveyed college students who reported having a hard time falling asleep on 3 or more days in the last week.
3. Divide the number of surveyed college students who reported having a hard time falling asleep on 3 or more days in the last week by the total number of surveyed college students who answered the question about difficulty falling asleep.
For example, if 1,000 college students were surveyed and 800 of them answered the question about difficulty falling asleep, and 200 of those 800 reported having a hard time falling asleep on 3 or more days in the last week, then the probability of a surveyed college student having a hard time falling asleep on 3 or more days in the last week would be 200/800, or 0.25, or 25%.

The number οf histοry bοοks is 180 that sοld in a week. The number οf chemistry textbοοks is 108 sοld in a week.
What is an equatiοn?There are many different ways tο define an equatiοn. The definitiοn οf an equatiοn in algebra is a mathematical declaratiοn that illustrates the equality οf twο mathematical expressiοns.
Given that the tοtal number οf bοοks that sοld in a week is 288.
The number οf chemistry textbοοks sοld was 72 less than the number οf histοry textbοοks sοld.
Assume that the number οf histοry textbοοks sοld was x.
The number οf chemistry textbοοks sοld was (x-72)
The tοtal number οf bοοks sοld was x + (x-72) = 2x - 72.
Accοrding tο the questiοn:
2x - 72 = 288
Add 72 frοm bοth sides:
2x - 72 + 72 = 288 + 72
2x = 360
Divide bοth sides by 2:
x = 360/2
x = 180
The number οf histοry textbοοks sοld was 180.
The number οf chemistry textbοοks sοld was (180-72) = 108.

find the probability of selecting a black checker from a bag of 6 black and 4 red checkers, replacing it and selecting another black
The probability of selecting a black checker from a bag of 6 black and 4 red checkers, replacing it, and selecting another black is 9/25.
To find the probability follow these-
Determine the probability of selecting a black checker on the first draw.
There are 6 black checkers and a total of 10 checkers (6 black + 4 red).
So, the probability of selecting a black checker on the first draw is 6/10,
which can be simplified to 3/5.
Since the black checker is replaced, there are still 6 black checkers and
a total of 10 checkers in the bag. Therefore, the probability of selecting a
black checker on the second draw is also 3/5.
To find the probability of both events occurring, multiply the probabilities together: (3/5) × (3/5) = 9/25.
So, the probability of selecting a black checker from a bag of 6 black and
4 red checkers, replacing it, and selecting another black is 9/25.

One face of a cube shaped Paco has an area of 7.6 square inches. What is the lateral surface area of the package
The lateral surface area of the cube shaped Paco is 45.6 square inches.
What is the lateral surface area of cube shape?In a cube, all six faces are identical squares, so there is no distinction between the lateral surface area and the total surface area. The surface area of a cube can be found by adding up the areas of all six faces.
If s represents the length of each edge of the cube, then the surface area S can be calculated using the formula: S = 6s²
So the lateral surface area of a cube with edge length s is simply 6 times the area of one of its faces, which is just the area of a square with side length s.
The Lateral surface area of a cube = 6s²
or we can say that, Lateral surface area = 6×(area of one face of a cube)
Given that the area of one face of a cube shaped Paco is 7.6 square inches.
Lateral surface area = 6×(7.6) = 45.6 square inches
Therefore, the lateral surface area of the cube shaped Paco is 45.6 square inches.

A box has a base area of 1.1 m2.
The box is placed on the ground and exerts a force of 4.5 kN.
What pressure is the force applied with?
Give your answer in kN/m2 and rounded to 2 dp.
Answer:
To find the pressure that the box exerts on the ground, we need to divide the force by the area of the base:
pressure = force / area
We are given that the force is 4.5 kN and the area is 1.1 m². However, we need to convert the force from kilonewtons to newtons before we can divide by the area:
force = 4.5 kN = 4,500 N
Now we can plug in the values:
pressure = 4,500 N / 1.1 m² = 4,090.91 N/m²
To express the pressure in kilonewtons per square meter, we need to divide by 1,000:
pressure = 4.09091 kN/m²
Rounding to 2 decimal places, we get:
pressure ≈ 4.09 kN/m²
Therefore, the pressure exerted by the box on the ground is approximately 4.09 kN/m².

How to solveGiven: Marks distribution in Mathematics
To Find: Plot an ogive, the median, the number of students who scored distinction marks (75% and above), and the number of students who passed the examination if the pass marks are 35%.
Solution:
Marks Number of students
Less than 10 7

Less than 30 54
Less than 40 71
Less than 50 84
Less than 60 105
Less than 70 147
Less than 80 180
Ogive:
An ogive is a graph that represents the cumulative frequency distribution of a set of data. To plot an ogive, we plot the upper limits of each class on the x-axis and the corresponding cumulative frequency on the y-axis. We then join the points with a free-hand smooth curve to obtain the ogive.
Median:
To find the median from the graph, we draw a line from the value of 50 on the y-axis to the ogive curve and then drop it down to the x-axis. The point where the line intersects the x-axis gives us the median. In this case, the approximate median value from the graph is 52.
The number of students who scored distinction marks:
To find the number of students who scored distinction marks (75% and above), we first calculate 75% of the total number of students, which is 0.75 x 180 = 135.
From the ogive graph, we see that the number of students who scored less than 75% marks is 105.
Therefore, the number of students who scored 75% or more marks is 180 - 105 = 75.
The number of students who passed the examination:
To find the number of students who passed the examination if the pass marks are 35%, we first calculate 35% of the total number of students, which is 0.35 x 180 = 63.
From the ogive graph, we see that the number of students who scored less than 35% marks is 28.
Therefore, the number of students who passed the examination is 180 - 28 = 152.

Here is a diagram of a person standing next to a lorry.
The diagram shows two centimetre rulers.
The person and the lorry are drawn to the same scale.
The lorry is approximately 11.2 m in length.
Using the scale diagram, estimate the height of the person in metres.
By using the scale diagram, the height of this person in meters is equal to 1.6 meter.
What is scale factor?In Geometry, the scale factor of a geometric figure can be calculated by dividing the dimension of the image (new figure) by the dimension of the pre-image (original figure):
Scale factor = Dimension of image (new figure)/Dimension of pre-image(actual figure)
Based on the information provided about the lorry, the lorry is approximately 11.2 m in length and 14 cm on a scale diagram. Therefore, the height of the person in meters can be calculated as follows;
1 centimeter = 11.2/14
1 centimeter = 0.8 meter.
Height of the person in meters = 0.8 meter × 2
Height of the person in meters = 1.6 meter.

degrees to get to a
90 degree angle.
Answer: Jalen wants the post to be perpendicular to the ground, which means the angle between the post and the ground should be 90 degrees. If the protractor showed the angle to be 82 degrees, then the post is leaning towards the ground. To make the post perpendicular, the angle needs to be decreased. Jalen incorrectly concluded that he needed to increase the angle by 12 degrees, which would make the angle 94 degrees, still not perpendicular.
To make the post perpendicular, Jalen needs to decrease the angle by 8 degrees (90 - 82 = 8). Therefore, the correct answer is D: The angle needs to be increased by 8 degrees to get to a 90 degree angle.

Of those who passed the 3 exams, how many passed the course if to pass it is
Do they need to pass at least 2 exams?
The number of students who passed the course is x + 3y, where x is smallest integer greater than or equal to[tex](180 - 3z)/53[/tex], and y = [tex](60 - 7x)/3[/tex] for equal things.
Let's use some variables to represent the number of students who passed each exam:
Let's call the number of students who passed all 3 exams "x".
Let's call the number of students who passed exactly 2 exams "3y" (since it's given that this number is triple the number who failed all 3 exams).
Let's call the number of students who passed exactly 1 exam "5x" (since it's given that this number is five times the number who passed all 3 exams).
Finally, let's call the number of students who failed all 3 exams "x".
We can use this information to set up a system of equations:
x + 3y + 5x + x = 60 (since there are 60 students in total)
x = x (since the number who failed all 3 exams is equal to itself)
Simplify:
7x + 3y = 60
Now we need to use the fact that passing at least 2 exams is required to pass the course. This means we need to find the number of students who passed at least 2 exams, which is the sum of the number who passed all 3 exams and the number who passed exactly 2 exams:
x + 3y
We know that this number needs to be greater than or equal to the number of students who pass the course. So we set up another equation:
x + 3y >= z (where z is the number of students who pass the course)
Now we can solve for x and y in terms of z. We'll start with y:
7x + 3y = 60
3y = 60 - 7x
y = (60 - 7x)/3
Next, we'll use the fact that the number who failed all 3 exams is equal to the number who passed all 3 exams:
x = x
Finally, we'll use this information to solve for x in terms of z:
x + 3y >= z
x + 3((60 - 7x)/3) >= z
x + (60 - 7x) >= 3z
53x >= 180 - 3z
x >= (180 - 3z)/53
Since x represents the number of students who passed all 3 exams, we want to round it up to the nearest integer (since we can't have a fractional number of students). So the final answer is:
The number of students who passed the course is x + 3y, where x is the smallest integer greater than or equal to (180 - 3z)/53, and y is given by y = (60 - 7x)/3.

2.One diagonal of a square measure (2x + 4) in. If the other diagonal

3.Given trapezoid QRST with QR//TS and UV as the median. If mQR = 12cm and mUV = 24 cm, what is mUV?

5.Given kite HOPE with diagonals mHP = 10 cm and m0E = 18 cm. What isthe area of the kite?
Answer:
1. The perimeter of a parallelogram is the sum of the lengths of all four sides. If two consecutive sides of a parallelogram measure 4 m and 9 m, respectively, then the other two sides must also measure 4 m and 9 m, respectively (since opposite sides of a parallelogram are equal in length). Therefore, the perimeter of the parallelogram is:
Perimeter = 4 m + 9 m + 4 m + 9 m = 26 m
So the perimeter of the parallelogram is 26 meters.
2. In a square, both diagonals are equal in length. If one diagonal measures (2x + 4) in and the other diagonal measures 16 in, then we can write:
2x + 4 = 16
Solving for x, we get:
x = 6
So the value of x is 6 inches.
3. In a trapezoid, the length of the median is equal to the average of the lengths of the two parallel sides. If QR is parallel to TS and mQR = 12 cm, then mTS must also be equal to 12 cm. Let x be the length of the base of the trapezoid.
Then, we have:
mUV = (mQR + mTS)/2
Substituting the given values, we get:
24 cm = (12 cm + 12 cm + x)/2
Simplifying, we get:
24 cm = (24 cm + x)/2
Multiplying both sides by 2, we get:
48 cm = 24 cm + x
Subtracting 24 cm from both sides, we get:
x = 24 cm
So the length of the base of the trapezoid is 24 cm, and the length of the median UV is 24 cm.

4. In an isosceles trapezoid, the diagonals are equal in length. If one diagonal measures 42 cm and one leg measures 23 cm, then we can use the Pythagorean theorem to find the length of the other leg:
d^2 = l^2 + (b/2)^2
where d is the length of the diagonal, l is the length of each leg, and b is the length of the base. Substituting the given values, we get:
42^2 = 23^2 + (b/2)^2
Simplifying, we get:
b^2/4 = 42^2 - 23^2
b^2/4 = 1253
Multiplying both sides by 4, we get:
b^2 = 5012
Taking the square root of both sides, we get:
b = sqrt(5012) ≈ 70.77
So the length of the other diagonal is also 42 cm.
5. The area of a kite is equal to half the product of the lengths of its diagonals. If mHP = 10 cm and mOE = 18 cm, then we can write:
Area = (mHP x mOE)/2
Substituting the given values, we get:
Area = (10 cm x 18 cm)/2 = 90 cm^2
So the area of the kite is 90 square centimeters.
I hope this helps! I'm sorry if this was wrong. If you need more help, ask me! :]
Un niño está haciendo volar dos cometas al mismo tiempo; tiene 380 pies de cuerda a una de las cometas y 420 pies para la otra. Él estima que el ángulo entre las dos cuerdas es de 30°. Aproxime la distancia entre las cometas.
Podemos utilizar la ley de cosenos para aproximar la distancia entre las cometas. Primero, necesitamos encontrar la longitud de la tercera cuerda, que conecta los puntos donde se cruzan las dos cuerdas que sostienen las cometas. Podemos usar trigonometría para encontrar la altura de este triángulo.
El ángulo opuesto a la altura es de 30°, por lo que podemos calcular la altura como:
sin(30°) = altura / 200altura = 100 piesAhora podemos usar la ley de cosenos para encontrar la longitud de la tercera cuerda:
d^2 = 380^2 + 420^2 - 2(380)(420)cos(30°)d^2 = 144400d ≈ 380 piesEntonces, la distancia entre las cometas es aproximadamente de 380 pies.

st Common Factor and Factoring Find the greatest common factor for the list of monomials. x^(3)y^(5)z^(3),y^(3)z^(3),xy^(3)z^(2) The GCF is
[tex]y^(3)z^(2)[/tex] is the greatest common factor for the given set of monomials.
The highest power of each variable that is shared by all of the given monomials must be identified in order to calculate the greatest common factor (GCF) for the given list of monomials. To put it another way, we must first determine the prime factors of each monomial before determining the factors that are shared by all the monomials.
Prime factorization for each monomial:
[tex]x^(3)y^(5)z^(3) = (x * x * x) * (y * y * y * y * y) * (z * z * z)y^(3)z^(3) = (y * y * y) * (z * z * z)xy^(3)z^(2) = (x) * (y * y * y) * (z * z)[/tex]
Factors are common to all monomials are [tex]y^(3), z^(2)[/tex]. The GCF is [tex]y^(3)z^(2)[/tex].
This is appropriate GCF by dividing each monomial by [tex]y^(3)z^(2)[/tex] and verify that result is whole number. For eg:
[tex]x^(3)y^(5)z^(3) / (y^(3)z^(2)) = x^(3)y^(2)zy^(3)z^(3) / (y^(3)z^(2)) = yzxy^(3)z^(2) / (y^(3)z^(2)) = x/y[/tex]

How many integers must be negative for the product of three integers to be negative? Explain. Find two different groups of three integers whose product is -12. Show your work.
Answer:
Step-by-step explanation:
To have the product of three integers be negative, we must have an odd number of negative integers. This is because when two negative integers are multiplied, the result is positive, and when an odd number of negative integers are multiplied, the result is negative. Therefore, we need at least one negative integer to produce a negative product, and then either one or three negative integers depending on whether the other two integers are positive or negative.
Here are two groups of three integers whose product is negative:
Group 1: {-1, 2, 3}
Product = (-1) x 2 x 3 = -6
In this group, there is one negative integer and two positive integers, which gives us an odd number of negative integers and a negative product.
Group 2: {-2, -3, 4}
Product = (-2) x (-3) x 4 = 24
In this group, there are two negative integers and one positive integer, which gives us an even number of negative integers and a positive product.
Note that there are infinitely many groups of three integers that can produce a negative product, as long as there is an odd number of negative integers in the group.
Gary works at a bicycle store in Vancouver. For the start of spring, the manager of the store has ordered 50 mountain bikes and 10 racing bikes.
Which conjecture is Gary most likely to make from this evidence?
Answer and Step-by-step explanation:
Based on the evidence provided, Gary is most likely to make the conjecture that the store expects high demand for mountain bikes in the spring compared to racing bikes. Another conjecture that could be made is that mountain bikes will most likely sell better than racing bikes. This is because the manager has ordered 50 mountain bikes, which is five times more than the number of racing bikes ordered. This suggests that the store is anticipating greater demand for mountain bikes than for racing bikes in the spring season.
