What is an algebraic expression?

An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots. Algebraic expressions are used to represent quantities and relationships between quantities in mathematical situations, often in the context of problem-solving.

Algebraic expressions can take many different forms, but some common examples include:

3x + 7

2a^2 + 5ab - 3b^2

(x + 2)(x - 5)

4x^2 - 9.

Let's start by figuring out how much the cat weighs now. We know that the cat weighs 7.3 times what it did when it was a kitten, and it weighed 0.6 kilograms when it was a kitten.

To find out how much the cat weighs now, we can multiply its original weight by 7.3:

0.6 kilograms x 7.3 = 4.38 kilograms

Therefore, So their cat weighs 4.38 kilograms now.

Answer:

  6

Step-by-step explanation:

You want the x-coordinate of the midpoint of segment AB with endpoint coordinates A(21, 5) and B(-9, -13).

The midpoint of a line segment has coordinates that are the average of the endpoint coordinates:

  M = (A +B)/2

  M = ((21, 5) +(-9, -13))/2 = (12, -8)/2

  M = (6, -4)

The midpoint of AB is (6, -4).

The x-coordinate of the midpoint is 6.

Answer:

x≈12.6

Step-by-step explanation:

We have the equation:

19(1.12^x) = 8(1.18^x)

Divide both sides by 8:

19/8 (1.12^x) = (1.18^x)

Take the natural logarithm of both sides:

ln[19/8 (1.12^x)] = ln[1.18^x]

Using the properties of logarithms, we can simplify the left side:

ln(19/8) + ln(1.12^x) = x ln(1.18)

Substituting y = 1.12^x, we get:

ln(19/8) + ln(y) = ln(1.18) y

Now we can solve for y:

ln(y) = ln(1.18) y - ln(19/8)

Using a numerical method or a graphing calculator, we can find that y ≈ 10.584.

Substituting back to solve for x:

1.12^x ≈ 10.584

Taking the logarithm base 1.12 of both sides:

x ≈ ln(10.584)/ln(1.12)

x ≈ 12.6

Therefore, the solution to the equation is x ≈ 12.6.

Hence, in answering the stated question, we may say that As a result, the circle length of a 30-degree arc of a 6-kilometer-diameter circle is approximately 1.57 kilometers.

Each spot that is a particular distance from yet another point creates a circle in the plane (center). As a result, it is a curve composed of points separated in the plane by a given distance. Furthermore, at all angles, it is circumferentially symmetric the about centre. Every couple of points in such a circle's closed, two at least plane is evenly spaced out from the "centre." A round symmetry line is formed by tracing a line through circle. Furthermore, at all angles, it is rotationally equal about the centre.

The circumference of a circle can be calculated using the formula C = d, where d is the circle's diameter. Because the diameter in this case is 6 kilometres, the circumference is:

C = d = (6) = 18.85 km (rounded to two decimal places)

1/12 = 30 degrees / 360 degrees

As a result, the length of the 30 degree arc is:

1.57 km length = (1/12) * C = (1/12) * 18.85 km (rounded to two decimal places)

As a result, the length of a 30-degree arc of a 6-kilometer-diameter circle is approximately 1.57 kilometres.

The chance of spelling C-H-A-N-C-E in this order with a bag of 15 scrabble tiles containing three each of the letters A, C, E, H, and N is 3/40040.

The chance of spelling C-H-A-N-C-E in this order with a bag of 15 scrabble tiles containing three each of the letters A, C, E, H, and N can be calculated by multiplying the probabilities of picking each letter in the correct order.

we need to calculate the probability of picking the letter C. There are three C's in the bag and a total of 15 tiles, so the probability of picking C is 3/15 or 1/5.

Next, we need to calculate the probability of picking the letter H. After picking the first letter, there are 14 tiles left in the bag and three H's, so the probability of picking H is 3/14. We can calculate the probabilities of picking the letters A, N, C, and E in the correct order:

- Probability of picking A: 3/13
- Probability of picking N: 3/12 or 1/4
- Probability of picking C: 2/11
- Probability of picking E: 3/10
To find the overall probability of spelling C-H-A-N-C-E in this order, we multiply all of these probabilities together:
[tex](1/5) * (3/14) * (3/13) * (1/4) * (2/11) * (3/10) = 18/240240 = 3/40040[/tex]

Step-by-step explanation:

The minimum number of people in the group should be 3.

In a group more than 1/2 are boys but there are less than 2/3 of the group.

Let the number of people in the group be x.

Therefore, the number of boys in the group is greater than 1/2 × x or x/2.

The number of people in the group is less than 2/3 × x or 2x/3.

As per the question, x > x/2 and x < 2x/3

multiply both sides by 2,

so we get:

2x > x and 2x < 4x/3.

Now, simplify the above equations as follows:

2x > x ⇒ x > 0 and

2x < 4x/3 ⇒ 6x < 4x ⇒ 0 < -2x ⇒ x < 0

Thus, it is not possible to have a group of 4 people as the number of people in the group is greater than 0.

The length of one of the sides of the GIVE WAY sign, equilateral triangle is approximately 200.89cm.

What is an equilateral triangle?

An equilateral triangle in geometry is a triangle with equally long sides. The three angles opposing the three equal sides are equal in size because the three sides are equal. As a result, with each angle measuring 60 degrees, it is sometimes referred to as an equiangular triangle. Equilateral triangles have the same area, perimeter, and height formula as other kinds of triangles.

Given that the triangle is an equilateral triangle, thus all sides are equal.

Let us suppose the sides = x.

The height of the equilateral triangle is given by:

height = (√3/2) x side length

Substituting the values:

110 = (√3/2) x (x)

x = 110 / (√3/2)

x ≈ 200.89cm

Hence, the length of one of the sides of the GIVE WAY sign is approximately 200.89cm.

Answer:

90 cm²

Step-by-step explanation:

Let the greater side be the length L and the smaller side the width W

Given L : W = 5 : 2

we can rewrite this as a fraction

[tex]\dfrac{L}{W} = \dfrac{5}{2}[/tex]

Cross-multiplying we get
2L = 5W

The perimeter of a rectangle
= 2(L + W)
= 2L + 2W
and we are told it is 42 cm

Therefore
2L + 2W = 42

Substitute 5W for 2L to get

5W + 2W = 42
7W = 42

or

W = 42/6 = 6

Given 2L + 2W = 42, substitute 6 for W to get

2L + 2(6) = 42

2L + 12 = 42

2L = 42 - 12= 30

L = 30/2 = 15

So length  L = 15

Just to check
L/W = 15/6 = 5/2  by dividing both numerator and denominator by 3

Area of the rectangle
= L x W

= 15 x 6

Answer:

a)  600 foxes

b)  720 foxes

Step-by-step explanation:

See attached spreadsheet.

The rate of population increase is 20% each year.  To find a new year's population, multiply the previous year's population by 0.20 (20%) and add that to the previous year.  Year 1 would be (500)*(0.20) = 100 new foxes which are added to the year 0 population of 500, which means there are (500+100) or 600 foxes in year 1.

Year 2:  (0.20)*(600) = 120 new foxes

Add 120 to the existing 600 to find 720 foxes in year 2,

============

A formula that can be used to predict the fox population for any year, n, would be:

     P(n) = 500*(1+0.20)^n

 where P(n) is the popluation at year n.  The 500 is the population at year 0 (the starting population).  (1+0.20) is the growth for each year (120%, which means the original population plus 20%).  That is raised to the year of interest, n.  [When n=0, (1+0.20)^0 = 1]

The measure of the angle x is 60 degrees and the sides of the triangle is 4√3 and 8.

According to the triangle sum theorem, a triangle's internal angles can be added up to 180 degrees. The triangle sum theorem, often referred to as the angle sum theorem of the triangle, states that the total of the measures of a triangle's internal angles in a Euclidean space adds up to 180 degrees, whether the triangle is acute, obtuse, or right. The smallest polygon with three sides and three internal angles, one at each vertex, and bordered by two neighbouring sides is a triangle.

Given that, angle B = 30 degrees and angle m = 90 degrees.

The sum of all the angles of a triangle is 180 degrees.

Thus,

30 + 90 + angle x = 180

120 + angle x = 180

angle x = 180 - 120

angle x = 60

The sides is thus a triangle with angle 30-60-90.

For this case the sides are in the ratio:

x : x√3 : 2x

From the figure we see that, x = 4.

Thus, the remaining sides are:

x√3 = 4√3 and 2x = 2(4) = 8

Hence, the measure of the angle x is 60 degrees and the sides of the triangle is 4√3 and 8.

To decrease a number by 16%, you should multiply it by 0.84.(1 - 0.16 = 0.84).

When you reduce a number by a percentage, you are subtracting that percentage from it. For example, if you were to decrease 100 by 16%, you would subtract 16 from 100 to get 84.

This is also known as a percentage decrease, which is the opposite of a percentage increase.

Using the formula for percentage decrease, we get:

Percentage decrease = (Decrease in value / Original value) × 100

We're told that to decrease a number by 37%, you multiply it by 0.63.

Therefore, we can write:

0.63 = (Decrease in value / Original value) × 1000.63 × Original value = Decrease in value

We want to find what you multiply a number by to decrease it by 16%, so let's call that value x.

So: x = (Decrease in value / Original value) × 100%

So, we can substitute in the values we know to solve for x:

x = (0.16 × Original value / Original value) × 100%x = 0.16 × 100%x = 16%

Therefore, to decrease a number by 16%, you should multiply it by 0.84.

What is whisker plot?

A whisker plot, also known as a box and whisker plot, is a graphical representation of a dataset that shows the distribution of values. It is often used to summarize and compare datasets, and to identify outliers or extreme values.

The plot is constructed using a rectangular box that represents the middle 50% of the data (the interquartile range or IQR). The box extends from the lower quartile (the value below which 25% of the data falls) to the upper quartile (the value below which 75% of the data falls). A line inside the box represents the median (the value below which 50% of the data falls).

Part A:

Here is a box and whisker plot representing the given data:

   |                   +                       |

75 -+                          +            |

65 -+-------------+-------------------+

   |  S  M  T  W |  T  F  S           |

The plot is divided into four sections: the lowest 25% of the data (the lower quartile), the next 25% of the data (the second quartile or median), the next 25% of the data (the third quartile), and the highest 25% of the data (the upper quartile). The box represents the middle 50% of the data, and the whiskers extend to the lowest and highest values that are not outliers.

Part B:

To determine which value is at a given percentile, we need to sort the data in ascending order and count how many values are less than or equal to the percentile we are interested in. Then we find the corresponding value in the sorted list.

For example, to find the value at the 60th percentile, we first calculate 60% of the total number of values, which is:

0.60 * 7 = 4.2

Since we cannot have a fraction of a value, we round up to the next integer, which is 5. This means that the value at the 60th percentile is the fifth value in the sorted list:

65, 66, 68, 70, 72, 74, 75

Therefore, the value at the 60th percentile is 72°F.

The probability that the mean weight of 36 different women is between 140LB and 211LB is approximately 0.9874.

There can only be one value for a random variable. A random variable's value could be zero with a probability of zero. A probability distribution's total probabilities are always equal to one.

a. We must convert the weight to a typical normal distribution using the following formula in order to determine the likelihood that a randomly chosen woman weighs between 140LB and 211LB.

z = (x - μ) / σ

If the weight x, the mean weight, and the standard deviation are all given. The probability can then be determined using a calculator or a typical normal table.

When x=140LB, we get:

z = (140 - 165) / 45.6 = -0.5461

x = 211LB results in:

z = (211 - 165) / 45.6 = 1.0096

The area under the standard normal curve between z = -0.5461 and z = 1.0096 is found to be roughly 0.6267 using a typical normal table or calculator.

Hence, the likelihood that a lady chosen at random weighs between 140LB and 211LB is roughly 0.6267.

b. We must normalise the sample mean to a standard normal distribution using the following method in order to determine the likelihood that the mean weight of 36 individual women is between 140LB and 211LB.

z is equal to (x - ) / (n / sqrt(n)).

When n is the sample size, x is the sample mean weight, is the mean weight, and is the standard deviation. The probability can then be determined using a calculator or a typical normal table.

To solve this issue, we have:

μ = 165LB

σ = 45.6LB

n = 36

If x = 140 LB, we get:

z = (140 - 165) / (45.6 / sqrt(36)) = -2.4994

With x = 211LB, we get:

z = (211 - 165) / (45.6 / sqrt(36)) = 2.4994

The area under the standard normal curve between z = -2.4994 and z = 2.4994 is found to be around 0.9874 using a standard normal table or calculator.

Hence, there is a roughly 0.9874 percent chance that the average weight of 36 individual women falls between 140LB and 211LB.

Therefore, P(X = 2) = (2 - 1)p(1-p), P(X = 4) = (4 - 1)p(1 - p)^3, P(X = 6) = (6 - 1)p(1 - p)^5, ...So, we haveP(A) = [(2-1)p(1-p)] + [(4-1)p(1-p)^3] + [(6-1)p(1-p)^5] + ...= p(1-p)[1 + 3(1-p)^2 + 5(1-p)^4 + ...]= p(1-p)/(1-(1-p)^2)= 2p(1-p) = 2/9.b) For a geometric random variable, we have E(X) = 1/p and Var(X) = (1 - p)/p^2.The expected value of e^X is:E(e^X) = Σ e^k (1-p)^(k-1) p= p Σ [e^(ln(1-p))]^(k-1) = p Σ (1-p)^(k-1)= p/(1-(1-p)) = 1/pAnd the variance of e^X is:Var(e^X) = E((e^X)^2) - [E(e^X)]^2= E(e^(2X)) - (1/p)^2= Σ e^(2k) (1-p)^(k-1) p - 1/p^2= p Σ [e^(2ln(1-p))]^(k-1) - 1/p^2= p Σ (1-p)^(2(k-1)) - 1/p^2= p/[1-(1-p)^2] - 1/p^2= (2-p)/(p(1-p)^2).c) P(e^X > 10) = P(X > ln(10)) = (1-p)^[ln(10)] = 0.0472 (approx.)

The step needed when constructing a circle circumscribed about a triangle is option B: Construct the perpendicular bisectors of each side of the triangle.

When constructing a circle circumscribed about a triangle, the center of the circle must lie at the intersection of the perpendicular bisectors of the sides of the triangle.

To construct the perpendicular bisector of a side, you need to find its midpoint and then draw a line perpendicular to the side passing through that midpoint.

By constructing the perpendicular bisectors of all three sides, you can find their point of intersection, which will be the center of the circle. Then, the radius of the circle can be found by measuring the distance from the center to any of the vertices of the triangle.

Therefore, Once you have the center and radius, you can draw the circle circumscribed about the triangle.
