For Spanish, the whiskers range from 55 to 95, and the box ranges from 60 to 85. A line divides the box at 70. For French, the whiskers range from 55 to 90, and the box ranges from 65 to 80. A line divides the box at 75. French Devonte inferred that his French scores have less variability than his Spanish scores. Which explains whether Devonte’s inference is correct? Devonte is correct because the range is greater for French. Devonte is correct because the interquartile range is less for French. Devonte is not correct because his highest grade is in Spanish. Devonte is not correct because the interquartile range is less for Spanish.

ax+z=aw-y for a

man i hate math ngl- please send help

Answers

Answer:

its a =y+z/w-x

Step-by-step explanation:

First, subtract

z and a w from each side of the equation to isolate the

a terms while keeping the equation balanced

than factor a A from each term on the left side of the equation

now divide each side of the equation by x-w to solve for a while keeping the equations balanced

you then multiply the right side of the equation by a form of 1 to rewrite the expression as

a=-1/-1 x -y & -z/ \-x/-w

than you remove the ones add a addition to y and the z and then you flip the x and the why and add multiplication

Subtract z first and aw from the equation to isolate the a terms while keeping the equation balanced.

ax-aw= -y-z

Then factor an a from each term.

a(x-w)=-y-z

Now, divide each side of the equation by x-w.

a = -y-z/x-w

Multiply the right side of the equation by a form of 1 to rewrite the expression.

A 25-foot magazine rack begins 20 feet south of the checkout desk and continues south. What are the coordinates of the beginning and end of the magazine rack? Explain or show how you got your answer. ANSWER CORRECTLY WITH AN EXPLANATION

Answers

Answer: The coordinates of the beginning of the magazine rack are (0,-20), and the coordinates of the end of the magazine rack are (0,-45).

Explanation:

The magazine rack begins 20 feet south of the checkout desk, so its starting point is 20 feet below the x-axis. This gives us the coordinates (0,-20) for the beginning of the rack. Since the rack is 25 feet long, it extends 25 feet to the south of its starting point. Therefore, the endpoint of the rack is 20 feet (the starting point) minus 25 feet (the length of the rack), or -5 feet south of the checkout desk. This gives us the coordinates (0,-45) for the end of the rack.

Brainliest?

The given information tells us that the magazine rack begins 20 feet south of the checkout desk and continues south for a length of 25 feet. Since the magazine rack is only moving in the south direction, we can say that the x-coordinate (horizontal distance) of both points will be the same.

Let's assign the x-coordinate of the checkout desk as 0. Then, the x-coordinate of the beginning and end of the magazine rack will also be 0.

The y-coordinate of the beginning of the magazine rack is 20 feet south of the checkout desk, which means it is 20 feet less than the y-coordinate of the checkout desk. If we assume that the y-coordinate of the checkout desk is y = 0, then the y-coordinate of the beginning of the magazine rack is y = -20.

To find the y-coordinate of the end of the magazine rack, we add the length of the rack (25 feet) to the y-coordinate of the beginning of the rack (-20 feet). This gives us y = 5.

Therefore, the coordinates of the beginning of the magazine rack are (0,-20) and the coordinates of the end of the magazine rack are (0,5).

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

$\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}$

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

$\hrulefill$

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Juan and Nina are in the Junior High Orchestra. As part of the orchestra they each have to learn two instruments. Juan is learning to play the violin and the cello. For every 3 hours that Juan spends practicing the violin, he practices the cello for 2.5 hours. Nina is learning to play the viola and cello. For every 3 hours Nina spends practicing the viola she practices the cello for 2 hours.

If Juan practiced the violin for 9 hours last week and Juan and Nina practiced the cello for the same amount of time, then Nina practiced the viola for ????
hours last week

Answers

Answer:

Nina practiced the viola for 11.25 hours last week.

Step-by-step explanation:

Juan practiced the violin for 9 hours last week. For each 3 hours that he practices the violin, he practices 2.5 hours of cello. So

3h violin - 2.5h cello

9h violin - xh cello

3x = 9 * 2.5

x = 7.5

He practiced 7.5 hours of cello, the same as Nina.

For every 3 hours Nina spends practicing the viola she practices the cello for 2 hours. So:

3h viola - 2h cello

xh viola - 7.5h cello

2x =3 * 7.5

x = 7.5 * 1.5

x = 11.25

Nina practiced the viola for 11.25 hours last week.

"Evaluate the expression.
78 - 2^4 ÷ (14 - 6) x 2"
please explain how you get your answer.
thanks

Answers

Answer:

equal to 74

Step-by-step explanation:

To evaluate the expression, we will follow the order of operations (PEMDAS):

Start with the exponent: 2^4 = 16Next, evaluate the division: 14 - 6 = 8Then, divide 16 by 8: 16 ÷ 8 = 2Next, multiply the result by 2: 2 x 2 = 4Finally, subtract 4 from 78: 78 - 4 = 74

So the expression 78 - 2^4 ÷ (14 - 6) x 2 is equal to 74.

Let’s use pemdas or bodmas
Let’s solve separately first

2^4 = 2’s power 4 = 2*2*2*2 = 16
14-6 = 8
2” = 2*2 = 4

78 - 16 / 8 * 4
= 78 - 2 * 4
= 78 - 8 = 70

Use the Midpoint Rule with $n=5$ to estimate the volume obtained by rotating about the y-axis the region under the curve $y=\sqrt{1+x^3}$, $0\leq x\leq 1$.

Answers

To estimate the volume using the Midpoint Rule with $\displaystyle n=5$, we need to divide the interval $\displaystyle 0\leq x\leq 1$ into $\displaystyle n$ subintervals of equal width. Since $\displaystyle n=5$, each subinterval will have a width of $\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}$.

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

$\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x$

where $\displaystyle y_{i}$ represents the value of the function $\displaystyle y=\sqrt{1+x^{3}}$ evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is $\displaystyle \Delta x=\frac{1}{5}$, the midpoint of the $\displaystyle i$-th subinterval is given by:

$\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}$

Substituting $\displaystyle x_{i}$ into the function $\displaystyle y=\sqrt{1+x^{3}}$, we obtain:

$\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}$

Now, we can calculate the approximate volume using the Midpoint Rule:

$\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x$

Substituting the values of $\displaystyle y_{i}$ and $\displaystyle \Delta x$ into the formula, we can evaluate the sum and compute the estimated volume.

The center's work depends on funding from multiple sources, including the general public. individual estates, and grants from corporations, foundations, and the federal government. Your department prepares an annual report of the center's accomplishments and financial status for the board of directors. It is mostly text with a few charts and tables, all black and white, with a simple cover. It is voluminous and pretty dry reading. It is inexpensive to produce other than the effort to pull together the content, which yequires time to request and expedite information from the center's other departments. At the last board meeting, the board members suggested the annual report be "upscaled" into a document that could be used for marketing and promotional purposes. They want you to mail the next annual report to the center's various stakeholders, past donors, and targeted high-potential future donors. The board feels that such a document is needed to get the center "in the same league" with other large not-for-profit organizations with which it feels it competes for donations and funds. The board feels that the annual report could be used to inform these stakeholders about the advances the center is making in its research efforts and its strong fiscal management for effectively using the funding and donations it receives. You will need to produce a shorter, simpler, easy-to-read annual report that shows the benefits of the center's research and the impact on people's lives. You will include pictures from various hospitals, clinics, and long-term care facilities that are using the results of the center's research. You also will include testimonials from patients and families who have benefited from the center's research. The report must be "eye-catching." It needs to be multicolor, contain a lot of pictures and easy-to-understand graphics, and be written in a style that can be understood by the average adult potential donor. This is a significant undertaking for your department, which includes three other staff members.

The board asks you to come to its next meeting on May 15 to present a detailed plan, schedule, and budget for how you will complete the project. The board wants the annual report "in the mail" by November 15 , so potential donors will receive it around the holiday season when they may be in a "giving mood."
