The box and whiskers plot is made up of five points: the minimum, the first quartile (Q1), the median (Med), the third quartile (Q3), and the maximum. The minimum is the lowest value in the dataset and the maximum is the highest value in the dataset.
What is median?Median is the middle number in a set of numbers when the numbers are arranged in order from least to greatest. It is a type of measure of central tendency, which provides an indication of the “middle” value in a set of numbers. It is often used to measure the average of a set of numbers, particularly when there are extremely large or small values in the set.
The box and whiskers plot for this set of data is a visual representation of the data that makes it easier to interpret. The first quartile is the value that is 25% of the way through the dataset and the third quartile is the value that is 75% of the way through the dataset. The median is the middle value in the dataset.
To create a box and whiskers plot for this set of data, the minimum is 2, the first quartile is 4, the median is 5, the third quartile is 10, and the maximum is 14. The box and whiskers plot would then be represented by the following graph:
| |

| | | | | | | | | | |
| 2 | 4 | 5 | 10 | 14 |
The box and whiskers plot graphically illustrates the spread of the data and allows us to easily compare the data to other datasets. It is also useful for identifying outliers in the dataset, as any value outside of the box and whiskers plot is considered an outlier.

The weight of Amara to the weight of toyin is 3:5, if Amara weighs 30 kg , how many more does Toyin weight?
Answer:
Toyin weighs 50 kg, which is 20 kg more than Amara.
Step-by-step explanation:
If Amara weighs 30 kg and the ratio of the weight of Amara to the weight of Toyin is 3:5, then we can set up a proportion:
3/5 = 30/x
where x is the weight of Toyin in kg.
To solve for x, we can cross-multiply:
3x = 150
x = 50
Therefore, Toyin weighs 50 kg, which is 20 kg more than Amara.
Find the value of the unknown base.
Log n 1/4=-1/2
Answer:
Therefore, the value of the unknown base is n = 16.
Step-by-step explanation:
Using the definition of logarithms, we have:
log_n(1/4) = -1/2
This equation can be rewritten as:
n^(-1/2) = 1/4
To solve for n, we can raise both sides to the -2 power:
n^(-1/2)^(-2) = (1/4)^(-2)
n = 16
Therefore, the value of the unknown base is n = 16.

Option (a) is correct i.e., the margin of error is equal to ± 0.8 and the confidence interval is equal to 10.5
What is Margin of Error?In a random survey sample, a “margin of error” is a measurement (calculation) that takes into consideration the difference between actual and sample data findings.
Let μ be the unknown population mean. To determine the ‘population mean’ we use the sample mean as a point estimate (approximate) μ.
The “margin of error” determines how far the actual population value will likely be from the survey's value. It evaluates the accuracy (precisely) of a survey's results. The survey's results are more likely to be accurate (precise) values if the “margin of error” is less.

Shift the graph of y=x+1 up 5 units
The equation for the shifted graph is y = x + 6.This equation represents the same line as the original equation, y = x + 1, but shifted up by 5 units.
Define shifting of graph?Shifting a graph involves moving it horizontally or vertically while maintaining the same shape and orientation.
To shift the graph of y = x + 1 up by 5 units, you need to add 5 to the y-coordinate of every point on the graph.
The original graph of y = x + 1 is a straight line with slope 1 and y-intercept 1.
To create the shifted graph, you can start by plotting a few points on the original graph and then adding 5 to their y-coordinates to get the corresponding points on the shifted graph.
Alternatively, you can use the general equation for a straight line, y = mx + b, where m is the slope and b is the y-intercept, to find the equation for the shifted graph.
The slope of the original graph is 1, so the slope of the shifted graph is also 1.
To find the y-intercept of the shifted graph, you can plug in x = 0 and y = 6 (since you want the graph to pass through the point (0, 6)) and solve for b:
6 = 1(0) + b
b = 6

According to the drag equation the velocity of an object moving through a fluid can be modeled by the equation 2 dvkvdt=− where k is a constant. a) Find the general solution to this equation. b) An object moving through the water has an initial velocity of 40 m/s. Two seconds later, the velocity has decreased to 30 m/s. What will the velocity be after ten seconds?
Answer:
The given differential equation is:
2dv/dt = -kv
where k is a constant.
a) To find the general solution to this differential equation, we can use separation of variables.
2dv/v = -k dt
Integrating both sides, we get:
2ln|v| = -kt + C1
where C1 is the constant of integration.
Taking exponential of both sides, we get:
|v|^2 = e^(C1) e^(-kt)
Since v can be either positive or negative, we can simplify the above equation as:
v = ±√(Ae^(-kt))
where A = e^(C1).
Therefore, the general solution to the given differential equation is:
v(t) = ±√(Ae^(-kt))
b) We are given that the initial velocity is 40 m/s and after 2 seconds, the velocity has decreased to 30 m/s. Let's use this information to find the value of A.
When t = 0, v = 40. Therefore,
40 = ±√(Ae^0)
40^2 = A
A = 1600
Now we can use the value of A to find the velocity after 10 seconds.
v(10) = ±√(1600e^(-10k))
We can use the information that the velocity has decreased to 30 m/s after 2 seconds to find the value of k.
30 = ±√(1600e^(-2k))
900 = 1600e^(-2k)
e^(-2k) = 0.5625
-2k = ln(0.5625)
k = -0.5 ln(0.5625)
Now we can substitute this value of k into the expression for v(10) to get:
v(10) = ±√(1600e^(5ln(0.5625)))
v(10) = ±√(1600(0.5625)^5)
v(10) = ±20.11 m/s
Therefore, the velocity of the object after ten seconds will be approximately 20.11 m/s.

The answer of the given question based on finding the area of the triangle the answer is the area of the given triangle is 15 square units.
What is Triangle?A triangle is three-sided polygon, which means it is closed shape with three straight sides and three angles. Triangles are some of most basic shapes in geometry and can be found in the many different contexts, from simple constructions to complex mathematical models.
To find the area of the triangle, we can use the formula A = (1/2)bh, where A is the area, b is the base, and h is the height.
Looking at the given triangle, we can see that the base is the line segment from (0, 0) to (6, 0), which has a length of 6 units.
The third vertex of the triangle appears to be at the point (2, 5), so we need to find the distance from this point to the base.
The equation of the base is y = 0, so the distance from the point (2, 5) to the base is:
d = |0(2) - 1(5) + 0| / sqrt(0² + 1²) = 5 / 1 = 5 units
Therefore, the height of the triangle is 5 units.
Now we can use the formula A = (1/2)bh to find the area:
A = (1/2)(6)(5) = 15 square units
Therefore, the area of the given triangle is 15 square units.

Wave heights at Folly Beach are normally distributed with a mean of 4 feet and a standard deviation of 1.5 feet.
What is the probability that a wave has a height of exactly 3 feet?
Answer:
Since wave heights at Folly Beach are normally distributed with a mean of 4 feet and a standard deviation of 1.5 feet, we can use the normal distribution formula to find the probability of a wave having a height of exactly 3 feet.
The formula for the normal distribution is:
P(x) = (1 / (σ * sqrt(2π))) * e^(-(x - μ)^2 / (2 * σ^2))
where:
P(x) is the probability density function
σ is the standard deviation
μ is the mean
e is the base of the natural logarithm
x is the value of the variable
Substituting the values given in the problem, we get:
P(3) = (1 / (1.5 * sqrt(2π))) * e^(-(3 - 4)^2 / (2 * 1.5^2))
P(3) = 0.176
Therefore, the probability that a wave has a height of exactly 3 feet is 0.176 or approximately 17.6%.

Therefore , the solution of the given problem of triangle comes out to be a length measures about 5.64 units in length.
What is a triangle exactly?If a polygon has more than one extra sections, it is a hexagon. It has a straightforward square form. Something like this configuration can only be distinguished from a conventional triangle by the sides A and B. The borders continue to be precisely collinear, but Euclidean geometry only yields a section rather than the entire cube. A triangular has three sides and three angles.
Here,
Let's determine the length of side b using the sine function:
opposite/hypotenuse of sin(A)
=> b/9 sin(50) = 9*sin(50) b = 7.021
Side B is therefore roughly 7.021 units long.
We can use the knowledge that the sum of the angles in a triangle is 180 degrees to determine the size of angle B:
=> angle B = 180 - angle A - 90
=> angle B = 180 - 50 - 90
=> angle B = 40 degrees
B's angle therefore has a 40 degree value.
The Pythagorean formula can also be used to determine the length of side a:
The equation is:
=> a² + b² = c²
=> a² + 7.021² = 9²
=> a² + 49.24 = 81
=> a² = 31.76
=> a ≈ 5.64

what are the possible numbers of positive, negative, and complex zeros of f(x)=3x^4-5x^3-x^2
Answer:
Counting the number of sign changes in the function f(x)
The number of positive roots is equal to the number of sign changes in the function f(x) or less than that by an even integer.
Here, f(x)=3x^4-5x^3-x^2 has two sign changes (from + to -, and from - to +), so the number of positive roots is either 2 or 0.
Counting the number of sign changes in the function f(-x)
The number of negative roots is equal to the number of sign changes in the function f(-x) or less than that by an even integer.
Here, f(-x)=3x^4+5x^3-x^2 has one sign change (from - to +), so the number of negative roots is either 1 or 0.
Counting the number of non-real roots (complex roots)
The number of non-real roots (complex roots) is equal to the difference between the total number of roots (4 in this case) and the number of real roots (which we found above).
Therefore, the possible number of positive roots is 2 or 0, the possible number of negative roots is 1 or 0, and the possible number of complex roots is 2 or 4.

Suppose you have $8,295 in savings when the price level index is at 100. If inflation pushes the price level up by 9 percent, calculate the real value of your savings.
Answer: To calculate the real value of your savings after inflation, you need to adjust your savings for the increase in the price level. Here's how to do it:
Calculate the amount of inflation:
Inflation rate = (New price level index - Old price level index) / Old price level index
In this case, the old price level index is 100, and the new price level index is 109 (100 + 9%). So:
Inflation rate = (109 - 100) / 100 = 0.09
Adjust your savings for inflation:
Real value of savings = Nominal value of savings / (1 + inflation rate)
In this case:
Real value of savings = 8,295 / (1 + 0.09) = 7,614.22
Therefore, the real value of your savings after inflation is $7,614.22.

Jose's family is renting a car for their family vacation. The car rental agency rents cars for $64 plus an additional charge of $0.20 per mile. The equation below represents the total cost of renting the car where x represents the number of miles driven.
No matter how many miles are travelled, only the standard rental fee of equation $64 is paid. The total cost of the rental is determined by multiplying the miles driven by the additional $0.20 per mile price.
What is equation?An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.
The following equation is used to calculate the overall cost of renting a car:
C(x) = 0.20x + 64
where x is the amount of miles driven and C(x) is the rental car's total cost.
No matter how many miles are travelled, only the standard rental fee of $64 is paid. The total cost of the rental is determined by multiplying the miles driven by the additional $0.20 per mile price.

i need help with question 15 i tried doing the problem 15 but i got stick on the problem 15
(Car Sales) Of the cars sold during the month of July, 87 had air conditioning, 99 had automatic transmission, and 73 had power steering. 8 cars had all three of these extras. 24 cars had none of these extras. 24 cars had only air conditioning, 64 cars had only automatic transmissions, and 35 cars had only power steering. 9 cars had both automatic transmission and power steering. How many cars had exactly two of the given options?
a) 64
b) 56
c) 96
d) 1
e) 82
Therefore , the solution of the given problem of unitary method comes out to be 25 vehicles had precisely two of the available options.
An unitary method is what?By multiplying the data obtained with such a nanosection variable whilst also two that used the unilateral strategy, the job can be finished. In essence, this mean that whenever a desired item appears, the specified entity is set or the colour space of both production runs is skipped. A varying fee of Inr ($1.01) might have been necessary for forty pens.
Here,
We can apply the inclusion-exclusion concept to resolve this issue. To begin, let's draw a Venn diagram to symbolise the supplied data:
where A is the proportion of vehicles with air conditioning, B is the proportion of vehicles with automatic gearbox, and C is the proportion of vehicles with power steering.
The information provided lets us know:
=> A = 87 + 8 + 24 = 119
=> B = 99 + 8 + 9 = 116
=> C = 73 + 8 + 9 = 90
=> A ∩ B ∩ C = 8
=> A ∩ B ∩ C' = 24 - 8 = 16
=> A ∩ B' ∩ C = 9
=> A ∩ B' ∩ C' = 64 - 9 - 8 - 16 = 31
=> A' ∩ B ∩ C = 0
=> A' ∩ B ∩ C' = 35 - 9 - 8 - 16 = 2
=> A' ∩ B' ∩ C = 0
=> A' ∩ B' ∩ C' = 24 - 8 - 16 - 2 = -2
Since there cannot be fewer than 0 cars without any extras, this number must be negative.
=> (A ∩ B' ∩ C) + (A ∩ B ∩ C') + (A' ∩ B ∩ C) = 9 + 16 + 0 = 25
As a result, 25 vehicles had precisely two of the available options. There may have been a mistake in the problem or the answer alternatives since the correct response is not one of the available choices.

Ms. Jan brought cookies for her class. She gave out half of them in the morning. At lunch, she gave out 12 more. She had 10 cookies left. How many cookies did she bring in?
Answer:
Step-by-step explanation:
44
Answer:
Step-by-step explanation:
Let [tex]c[/tex] be the total cookies.
[tex]\frac{1}{2}c+12+10=c[/tex]
[tex]\frac{1}{2}c+22=c[/tex]
[tex]c+44=2c[/tex] (multiplied both sides by 2)
[tex]44=c[/tex] (subtracted c from both sides)
[tex]c=44[/tex]
She began with 44 cookies.

What is triangle?A triangle is a closed two-dimensional plane figure with three straight sides and three angles. It is one of the basic shapes in geometry, and it is formed by connecting three non-collinear points with line segments. The sum of the three angles in a triangle is always 180 degrees. Triangles can be classified based on their side lengths and angle measures, and they have important properties and applications in various fields, including mathematics, science, engineering, and art.
Here,
Since triangles ABC and XYZ are similar, their corresponding sides are in proportion. We can set up the following proportion using the given side lengths:
AC/XY = BC/YZ
Substituting the given values, we get:
2/54 = 6/x
Cross-multiplying, we get:
2x = 54 × 6
2x = 324
Dividing both sides by 2, we get:
x = 162 units
