Which box plot represents the data set?

Circle A and circle A' have the same circumference and the radii of circle A and circle A' have the same lengths. Therefore, options A and B are the correct answers.

Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.

Given that, circle A' is the result of rotating circle A by 180° about point P.

When we rotate any object its shape and size does not change, only its position changes.

Therefore, options A and B are the correct answers.

So if they sell approximately 376 pizzas the first shift and then the same amount for the second, all you have to do is add 376 by 367 or multiply by 2 because adding the same number twice is like multiplying the number by 2.

Answer: 564

Step-by-step explanation: From 10-2 they sell 376 pizzas. So, in 4 hours they sell 376 pizzas, and they sell 94 pizzas per hour, because 376/4 is 94. So from 5-7, 2 hours, they should sell 94 times 2 pizzas, which is 188 pizzas. So 188+376 is 564.

Parabola A and parabola B are similar in that they are both vertically oriented parabolas with the x-axis as their axis of symmetry. However, they differ in their vertex, focus, and directrix, which means they have different equations and open in different directions.

Both parabola A and parabola B are examples of vertically oriented parabolas that have the x-axis as their axis of symmetry. However, they differ in their vertex, focus, and directrix.

Parabola A has its vertex at (0, 0) and its focus at (0, 4). The directrix is the line y = -4, which is a horizontal line 4 units below the vertex. This means that any point on parabola A is equidistant to the vertex and the focus, and the distance between any point on the parabola and the directrix is equal to the distance between the point and the focus.

Parabola B has its vertex at (0, 0) and its focus at (0, -6). The directrix is the line y = 6, which is a horizontal line 6 units above the vertex. This means that any point on parabola B is equidistant to the vertex and the focus, and the distance between any point on the parabola and the directrix is equal to the distance between the point and the focus.

In terms of their equations, the equation of parabola A is y^2 = 16x, while the equation of parabola B is y^2 = -24x. Notice that parabola B has a negative coefficient of x, which means it opens to the left instead of the right like parabola A.

The statements, Students are more likely to own exactly 2 devices than any other number, Less than half as many students own 3 or more devices as compared to students who own 1 device and About 10 more students own 1 device than own 3 or more devices are true.

It is a branch of mathematics that deals with the occurrence of a random event.

Students are more likely to own exactly 2 devices than any other number is

true because the number of students own exactly 2 devices is greater than the other categories.

Less than half as many students own 3 or more devices as compared to students who own 1 device is true because 18 students own 1 device, the half of them is 9, and the number of students own 3 or more devices is 7 which is less than 9.

About 10 more students own 1 device than own 3 or more devices is true because the difference between students own 1 device and those own 3 or more devices = 18 - 7 = 11 which is about 10 more.

The amount the the home buyer saves in total by choosing Loan A is  most closest to $11,427. The Option B is correct.

In order to compare the total cost of each loan, we need to consider both the monthly payment and the discount points.

For Loan A, we have Loan amount: $390,000, Loan term: 15 years, Discount points: 4 and Monthly payment: $3,509.71. For Loan B, we have Loan amount: $390,000, Loan term: 15 years Discount points: 0 and  Monthly payment: $3,659.86.

The total cost of Loan A is the sum of the discounted upfront cost (discount points) and the total of all monthly payments over the life of the loan:

= (4% of $390,000) + ($3,509.71 x 180)

= $15,600 + $631,948.80

= $647,548.80

The total cost of Loan B is the total of all monthly payments over the life of the loan:

= ($3,659.86 x 180)

= $658,574.80

Now, the amount saved by choosing Loan A over Loan B is the difference between their total costs which equals:

= Total cost of Loan B - Total cost of Loan A

= $658,574.80 - $647,548.80

= $11,026

If the triangles are similar but no congruent, then the triangles have different size, thus the only correct option is the dilation (first option).

We know that two figures are congruent if the figures have the same shape and size, while two figures are similar only if have the same shape (but the figures can have different size).

Here we know that the triangles are similar but no congruent, so the triangles must have different size. From the given transformations, the only one that changes the size is the first option, a dilation.

And for example, if we apply a dilation AND the other transformations, then we still will get a similar figure, but if we apply a reflection/rotation/translation alones, we will get a congruent triangle.

Step-by-step explanation:

You want the area of icing on a cake 13 cm high and 17 cm in radius.

The area of the top is ...

  A = πr²

The area of the side is ...

  A = 2πrh

Then the total area of icing on the cake is ...

  πr² +2πrh = πr(r +2h)

  = 3.14(17 cm)(17 cm + 2·13 cm) = 2295.34 cm²

The area of icing needed for the cake is about 2295 cm².

The work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium is 34,300 J.

First we need to calculate the total amount of water that needs to be lifted and the height it needs to be lifted to.

The volume of water in the aquarium is given by:

V = 7 m * 1 m * 1 m = 7 m^3

Since we need to pump out the top half of the water, the volume of water that needs to be lifted is:

V = (1/2) * 7 m^3 = 3.5 m^3

The mass of the water can be calculated as:

m = V * density of water = 3.5 m^3 * 1000 kg/m^3 = 3500 kg

The height that the water needs to be lifted to is equal to the height of the aquarium, which is 1 m.

The work needed to lift the water can be calculated using the formula:

W = m * g * h

where

So, the work needed is:

W = 3500 kg * 9.8 m/s^2 * 1 m = 34,300 J (joules)

Therefore, the work needed to pump the top half of the water out of the aquarium by raising it over the top of the aquarium is 34,300 J.

The total cost of the trip is a function of the velocity v is:

Cost (v) = 500v + 400/v

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Distance = 500 km

Velocity = v km/h

Now,

Velocity = Distance /Time

Time = distance/velocity

= 500 / v

The total cost of the trip.

Cost = fuel cost per hour x time + other costs per hour x time

= v² x 500/v + 400 x 500/v

The statements are:

y=e" and y = ln x are inverses.

This is false. The inverse of y = e^x is y = ln x, and the inverse of y = ln x is y = e^x. So, the two functions y = e^x and y = ln x are inverses of each other, but y = e^x and y = e^ln x are not.

In een In(x) = log. (x)

This is false. The statement should be: e^ln(x) = x, which is true by the definition of logarithms.

ln e = 1

This is true. The natural logarithm of e is 1.

In (x) = log10 (x)

This is false. The statement should be: log10(x) = log(x) / log(10).

In e = 10

This is false. The natural logarithm of e is 1.

In(e) and en both equal x.

This is false. In(e) = 1, and e^n = x does not necessarily imply that In(e) = x.
