Find the equation of the linear function represented by the table below in slope-intercept form.

cone’s radius r in terms of y is  r = 2(y + 5).

The quantity of space a cone encloses is referred to as its volume. It is the measure of the three-dimensional space occupied by the cone.

volume of a cone with a height of 9 inches as:

V = 3πy² + 30πy + 75π

Also, we are aware that the formula for a cone's volume with height hand radius r is

V = 1/3πr²h

Since we are looking for the radius of the cone in terms of y, we need to express h in terms of y. We can do this by noting that the height of the cone is 9 inches, and that it is made up of two parts: a smaller cone with height y and a larger frustum with height (9-y). The radius of the smaller cone is r/y times the radius of the larger frustum, so we can write:

h = y + (9 - y) = 9

r/y = r/(r + 3y)

As a result, the cone's volume may be represented as:

V = 1/3πr²(y + (9 - y))

= 1/3πr²(9)

Equating this to the given volume, we get:

1/3πr²(9) = 3πy² + 30πy + 75π

Simplifying and solving for r, we get:

r = √(4(y² + 10y + 25))

r = 2√(y² + 10y + 25)

Therefore, the cone's radius in terms of y is:

r = 2(y + 5)

So the answer is r = 2(y + 5).

Answer:

C John should order 6 pizzas because if he orders 5 pizzas, he will be short 2 slices.

Step-by-step explanation:

14 people need 3 slices each.  We need to multiply.

14*3 = 42

Each pizza has 8 slices so divide by 8

42 /8 =  5   remainder 2

We round up to make sure to have enough.

We need at least 6 pizzas to have enough.  He is short 2 slices.

Answer:

C)

Step-by-step explanation:

John wants to order enough pizzas for 14 people to have 3 slices each. This means that he would need at least 42 slices of pizza:

[tex]14 * 3 = 42[/tex]

It is given that pizza has 8 slices. Divide 8 from 42:

[tex]\frac{42}{8} = 5.25[/tex]

Note that he cannot order .25 of a pizza, and so he will have to order 6.

C) John should order 6 pizzas because if he orders 5 pizza, he will be short 2 slices.

Answer: The composite figure consists of two square pyramids, so we can find the total surface area by adding the surface area of each pyramid. The surface area of a square pyramid is given by:

S = B + (1/2)Pl

where B is the area of the base, P is the perimeter of the base, l is the slant height, and S is the total surface area.

For each pyramid, we have:

B = 24^2 = 576 cm^2

P = 4(24) = 96 cm

l = sqrt(24^2 + 5^2) = 25 cm

So the surface area of each pyramid is:

S = 576 + (1/2)(96)(25)

S = 576 + 1200

S = 1776 cm^2

Therefore, the total surface area of the composite figure is:

2S = 2(1776)

= 3532 cm^2

The expression that represents the total surface area, in square centimeters, of the figure is:

(24) (24) + 8 (one-half (24) (5)) + 8 (one-half (24) (13)) = 576 + 480 + 624 = 1680 cm^2

This expression only accounts for the surface area of the base and the triangular faces, but it does not include the surface area of the pyramid faces. So it is not correct.

The correct answer is:

8 (one-half (24) (5)) + 8 (one-half (24) (13)) = 480 + 624 = 1104 cm^2

which only represents the surface area of the triangular faces of both pyramids. To get the total surface area, we need to add the surface area of the base, which gives:

1104 + 2(576) = 2256 + 1104 = 3360 cm^2

Therefore, the total surface area of the composite figure is 3360 square centimeters.

Answer:

An exponential function has the form `f(x) = ab^x`, where `a` and `b` are constants. To find the exponential function that passes through the points `(-2,1)` and `(-1,2)`, we can use these points to set up a system of equations to solve for the values of `a` and `b`.

Substituting the coordinates of the first point into the equation for an exponential function gives us:

`1 = ab^(-2)`

Substituting the coordinates of the second point into the equation for an exponential function gives us:

`2 = ab^(-1)`

Dividing these two equations gives us:

`(2)/(1) = (ab^(-1))/(ab^(-2))`

`2 = b`

Now that we know that `b=2`, we can substitute this value back into either equation to solve for `a`. Substituting into the first equation gives us:

`1 = a(2)^(-2)`

`1 = a(1/4)`

`a = 4`

So, the exponential function that passes through the points `(-2, 1)` and `(-1, 2)` is given by:

`f(x) = 4 * 2^x`.

To find the exponential function for the graph passing through (-2,1) and (-1,2), we need to use the general form of an exponential function, which is:

y = a * b^x

where:

a is the initial value or the y-intercept of the function

b is the base of the exponential function

x is the variable or the exponent

To determine the values of a and b, we need to use the two given points and solve for the corresponding equations. Substituting the first point (-2,1), we get:

1 = a * b^(-2)

Substituting the second point (-1,2), we get:

2 = a * b^(-1)

Now, we can solve for a and b by eliminating one variable. Dividing the second equation by the first equation, we get:

2/1 = a * b^(-1) / (a * b^(-2))

2 = b

Substituting this value of b into the first equation, we get:

1 = a * 2^(-2)

a = 4

Therefore, the exponential function that passes through (-2,1) and (-1,2) is:

y = 4 * 2^x

or

f(x) = 4 * 2^x

After answering the provided question, we can conclude that Therefore, coordinates   the length of the midsegment of the trapezoid is [tex]\sqrt(13)[/tex]units.

In mathematics, a coordinate is a number or permutation of integers that indicates the location of a point or object in space. Coordinates are frequently used to define a point or object's position in a specific reference frame, such as the Euclidean or antarctic coordinate systems. In the Cartesian coordinate system, a point is located by its distance from the origin along the x-axis and its distance first from origin along the y-axis. These distances are represented by two numbers, its x-coordinate and the y-coordinate. The point's position in the plane is specified by the two coordinates.

To find the length of the midsegment of a trapezoid,

[tex]E = ( (x1 + x2)/2 , (y1 + y2)/2 )\\So, E = ( (0+2)/2 , (3+5)/2 ) = (1,4)\\F = ( (x3 + x4)/2 , (y3 + y4)/2 ) = ( (6+2)/2 , (4+0)/2 ) = (4,2)\\d = \sqrt( (x2 - x1)^2 + (y2 - y1)^2 )\\d =\sqrt( (4-1)^2 + (2-4)^2 ) = \sqrt(9+4) = \sqrt(13)\\[/tex]

Therefore, the answer is D. Block 1 IQR: 20; Block 2 IQR: 5. Therefore, the answer is B. Block One: 25, Block Two: 100. Therefore, the answer is B. Block 1 is skewed right, Block 2 is skewed left. Therefore, the answer is option A: mean: 76.5, standard deviation: 21.6.

In statistics, the mean (or arithmetic mean) is a measure of central tendency of a set of numerical data. It is calculated by adding all the values in the dataset and dividing by the number of values. The mean is often used as a representative value for a dataset, as it provides a single value that summarizes the entire dataset. However, it can be affected by extreme values (outliers) in the dataset.

Here,

1. To find the interquartile range (IQR) for each block, we first need to determine the quartiles. We can do this by finding the median (Q2) of each block, and then finding the median of the lower half (Q1) and upper half (Q3) of the data.

For Block 1:

Q1: median of {25, 60, 70, 75, 80} = 70

Q2: median of {85, 85, 90, 95, 100} = 90

Q3: median of {70, 75, 80, 85, 90} = 80

IQR = Q3 - Q1 = 80 - 70 = 10

For Block 2:

Q1: median of {70, 70, 75, 75, 75} = 75

Q2: median of {75, 75, 80, 80, 85} = 80

Q3: median of {80, 85, 100, 75, 75} = 82.5

2. To identify outliers, we can use the 1.5 x IQR rule. Any data point that is more than 1.5 x IQR above Q3 or below Q1 is considered an outlier.

For Block 1:

Q1 = 70

Q3 = 80

IQR = 10

1.5 x IQR = 15

The only data point that is more than 15 above Q3 is 100, so it is an outlier.

For Block 2:

Q1 = 75

Q3 = 82.5

IQR = 8

1.5 x IQR = 12

There are no data points that are more than 12 above Q3 or below Q1, so there are no outliers.

3. To determine if each block's data is symmetric, skewed left, or skewed right, we can examine the shape of the distribution.

For Block 1, the data is:

Highest at 100, with several values clustered around the upper end of the range.

No values below 25, which suggests a lower boundary.

Median is 90.

No values are particularly isolated from the rest of the data.

This suggests that Block 1 is skewed right.

For Block 2, the data is:

Highest at 75, with several values clustered around the middle of the range.

No values below 70, which suggests a lower boundary.

Median is 80.

No values are particularly isolated from the rest of the data.

This suggests that Block 2 is skewed left.

4. To find the mean of Block 1, we add up all the scores and divide by the number of scores:

mean = (25 + 60 + 70 + 75 + 80 + 85 + 85 + 90 + 95 + 100) / 10

mean = 765 / 10

mean = 76.5

To find the standard deviation of Block 1, we need to first calculate the variance.

To do that, we can use the formula:

variance = (sum of (each score - mean)²) / (number of scores - 1)

First, we'll find the sum of (each score - mean)²:

(25 - 76.5)² = 2562.25

(60 - 76.5)² = 270.25

(70 - 76.5)² = 42.25

(75 - 76.5)² = 2.25

(80 - 76.5)² = 12.25

(85 - 76.5)² = 71.25

(85 - 76.5)² = 71.25

(90 - 76.5)² = 182.25

(95 - 76.5)² = 379.25

(100 - 76.5)² = 562.5

Next, we'll add up these values:

2562.25 + 270.25 + 42.25 + 2.25 + 12.25 + 71.25 + 71.25 + 182.25 + 379.25 + 562.5 = 3154.5

Now we can plug this into the variance formula:

variance = 3154.5 / 9

variance = 350.5

Finally, to get the standard deviation, we take the square root of the variance:

standard deviation = √(350.5)

standard deviation = 18.7 (rounded to one decimal place)

To calculate the difference when -6c + 4 is subtracted from -8 + 7c, we must first expand the terms. The first term, -6c, can be broken down into -6 x c, which simplifies to -6c. The second term, 4, can remain as is. The third term, -8, can also remain as is. The fourth term, 7c, can be broken down into 7 x c, which simplifies to 7c.

We can then calculate the difference by performing the subtraction. We begin by subtracting the second term, 4, from the first term, -6c. We can do this by adding -4 to -6c, which results in -6c - 4. We then subtract the fourth term, 7c, from the third term, -8. We can do this by adding 8 to -7c, which results in -7c + 8.

The probability that the sample mean is between 50.9 and 51.5 is approximately 0.0998.

We can use the central limit theorem to find the probabilities of the given events. According to the central limit theorem, if we take random samples of size n from a population with mean μ and standard deviation σ, the sample means will be approximately normally distributed with mean μ and standard deviation σ/√n.

a. To find the probability that the sample mean is greater than 53, we first calculate the z-score of the sample mean:

[tex]$z=(x-\mu) /(\sigma / \sqrt{n})=(53-50) /(19 / \sqrt{ } 64)=1.684$[/tex]

Using a standard normal distribution table or calculator, we find that the probability of a z-score being greater than 1.684 is 0.0455. Therefore, the probability that the sample mean is greater than 53 is approximately 0.0455.

b. To find the probability that the sample mean is less than 53, we use the same formula and calculate the z-score:

[tex]$z=(x-\mu) /(\sigma / \sqrt{ } n)=(53-50) /(19 / \sqrt{ } 64)=1.684$[/tex]

The probability of a z-score being less than 1.684 is 1 - 0.0455 = 0.9545. Therefore, the probability that the sample mean is less than 53 is approximately 0.9545.

c. To find the probability that the sample mean is less than 47, we again use the formula for the z-score:

[tex]$z=(x-\mu) /(\sigma / \sqrt{ } n)=(47-50) /(19 / \sqrt{ } 64)=-1.684$[/tex][tex]$z 1=(47.5-50) /(19 / \sqrt{ } 64)=-0.842$[/tex]

The probability of a z-score being less than -1.684 is the same as the probability of a z-score being greater than 1.684, which we found to be 0.0455. Therefore, the probability that the sample mean is less than 47 is approximately 0.0455.

d. To find the probability that the sample mean is between 47.5 and 51.5, we first calculate the z-scores of the two endpoints:

[tex]z_1[/tex] = (47.5 - 50) / (19/√64) = -0.842

[tex]z_2[/tex]= (51.5 - 50) / (19/√64) = 0.842

Using a standard normal distribution table or calculator, we find that the probability of a z-score being between -0.842 and 0.842 is 0.6603. Therefore, the probability that the sample mean is between 47.5 and 51.5 is approximately 0.6603.

e. To find the probability that the sample mean is between 50.9 and 51.5, we first calculate the z-scores of the two endpoints:

Jimmy's living space really gauges 24 feet by 16 feet in light of the fact that every 2 cm on the size attracting is equal to 8 feet.

We can utilize this scale variable to decide the genuine dimensions of the rectangle room in the event that each 2 cm on the scale attracting relates to 8 feet.

We should initially sort out the number of 2 cm units there that are in the scale drawing's length and expansiveness.

Length: 6 cm ÷ 2 cm = 3 units

Width: 4 cm ÷ 2 cm = 2 units

Thus, the size drawing is 3 by 2 units.

Next, we can interpret the dimensions of the scale bringing into genuine dimensions utilizing the scale variable of 2 cm = 8 feet:

Length: 3 units times 8 feet for every unit approaches 24 feet

Width: 2 units times 8 feet for every unit approaches 16 feet

Jimmy's living space really gauges 24 feet by 16 feet in light of the fact that each 2 centimeters on the size attracting is comparable to 8 feet.

The point of intersection is (6, 6).


To find the point where two lines intersect, we need to solve the system of equations:

y = 2x - 6 (equation 1)

y = 1/2x + 3 (equation 2)

We can solve this system by setting the two expressions for y equal to each other:

2x - 6 = 1/2x + 3

Multiplying both sides by 2 to eliminate the fraction, we get:

4x - 12 = x + 6

Subtracting x and adding 12 to both sides, we get:

3x = 18

Dividing by 3, we get:

x = 6

Now we can plug this value of x into either equation to find the corresponding y-coordinate. Let's use equation 1:

y = 2(6) - 6 = 6

Therefore, the point of intersection is (6, 6).

If the slopes are equal, the reflected line segments are parallel.

When a line segment is reflected in the y-axis, its image is formed by reflecting each point on the segment across the y-axis.

This means that the x-coordinate of each point is negated, while the y-coordinate remains the same.
To draw the images of Wayne Street and George Street, we need to know their coordinates.

Let's assume that Wayne Street runs from (2, 3) to (6, 5), while George Street runs from (-1, -2) to (-5, -4).
When we reflect Wayne Street in the y-axis, we negate the x-coordinates and keep the y-coordinates the same.

This gives us the image of Wayne Street, which runs from (-2, 3) to (-6, 5).

Similarly, when we reflect George Street in the y-axis, we get the image of George Street, which runs from (1, -2) to (5, -4).
We need to consider the slopes of the original segments and their images.

The slope of Wayne Street is (5-3)/(6-2) = 1/2, while the slope of George Street is (-4-(-2))/(-5-(-1)) = -1/2.
When we reflect a line segment in the y-axis, its slope is negated.

So,

The slope of the image of Wayne Street is -1/2, while the slope of the image of George Street is 1/2.
Therefore, the images of Wayne Street and George Street are not parallel, since their slopes are opposite.

In fact, they are perpendicular to each other, since the product of their slopes is (-1/2) x (1/2) = -1/4, which is equal to -1 (the negative reciprocal of each other).

Answer:

(1 - 5x + y)(1 + 5x - y).

(9a - c + 3b)(9a + c - 3b).

(bc - b - c - 1)(bc + b + c - 1).

Step-by-step explanation:

1 - 25x^2 + 10xy - y^2

= 1 - (25x^2 - 10xy + y^2)

= 1 - (5x - y)^2

This is the difference of 2 squares, so the answer is

(1 - (5x - y))(1 + (5x - y))

= (1 - 5x + y)(1 + 5x - y).

81a^2 + 6bc - 9b^2 - c^2

= 81a^2 - (c^2 - 6bc + 9b^2)

= 81a^2 - (c - 3b)^2

= (9a - (c - 3b))(9a  + (c - 3b))

= (9a - c + 3b)(9a + c - 3b)

b^2c^2 - 4bc - b^2 - c^2 + 1

= b^2c^2 - 4bc - b^2 - (c^2 - 1)

= (bc - b)  - (c + 1))((bc + b) + (c - 1)

= (bc - b - c - 1)(bc + b + c - 1).

More than 1 triangles can be constructed with the angles 110°, 50°, and 20°.

Three non-collinear points are connected with straight line segments to create the two-dimensional geometric shape known as a triangle. The triangle's three points are referred to as its vertices, and the line segments that link them as its sides. Triangles are named based on their sides and angles.  

In the given triangles,

angles are 110, 50 and 20.

we can construct on triangle by using these angles.

Now, 110 angle subtend longest side, 20 subtend shortest side as well as, 50 subtend third side.

Sides length are not mentioned.

So, we can construct one infinite triangle by scaling the length of sides.
