During the winter months, there is a decrease of between 10 and 30 percent in business at a certain restaurant. Which of the following could not be the percent that winter business is of the normal business?

Answers

Answer 1

Answer:

  d.  94

Step-by-step explanation:

If business decreases 10%, it is 100% - 10% = 90% of normal.

If business decreases 30%, it is 100% -30% = 70% of normal.

if business is 94% of normal, it is not between these values, so is not a winter business statistic.

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside


Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

V= 2799.16

V=πr^2h

You have the diameter which is 2 times to radius. In order to get the radius you half the diameter which is 9.

9 to the second power is 81. Then you multiply it by the height which is 11. 81 x 11 is 891. So 891 x pi would be about 2799.16.
The radius is half of the diameter;
2r=d 2 r = d.

So plug in 18m in as d.
2r=18
/2 /2
r= 9

The volume of a cylinder is v= πr^2h
Use Pi symbol in calculator unless specified to use 3.14
The height is 11m

V=πr^2h
V= π(9)^2(11)
V= π(81)(11)
V= π(891)
V= 2,799.159054348506
So, to the nearest whole number: v= 2,800 m

Help me, I tried doing it but the answers were wrong, help. I have to make this percentage into a fraction,

Answers

Answer:

Step-by-step explanation:

we know that 100% is equal to 1 so,

100%---1

2.5---x

100x=2.5

x=0.025

2.5% is 25/1000 as a fraction.

First, turn it in a decimal by moving the decimal point 3 places to the left.

2.5% as a decimal is 0.025 then just read it out loud which would be “25 thousandths” so it’s 25 over one thousand or 25/1000.
You can simplify it by dividing both the numerator (top number) and denominator (bottom number) by 25 to make it 1/40.

A school assembly had 600 students in attendance, and 35% of them were first-graders. How many first-graders were at the assembly?

can u also list the formula on how to do this while ur at it pls and ty

Answers

Answer:

210 Were First Graders

Step-by-step explanation:

35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:

35/100 = X/600

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

35/100 = X/600

X/600 = 35/100

X*600/600 = 35*600/100

X = 21000/100

X = 210

The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 35 percent of 600?", Y is 600 and P is 35:

(600 * 35)/100 = 210

And once again you see that the answer is 210.

Answer:

210 kids

Step-by-step explanation:

So the formula is basically part over whole is equal to x/100%

So for here it would be x/600 = 35/100

Solve that and you will get 210

The value of A/B is given as follows:

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Two intersecting lines. The angle formed at the top is labeled 3 x plus 50 degrees. The angle formed at the bottom directly opposite it is labeled 6 x minus 10 degrees.

Answers

We know that the two angles are opposite and therefore are equal, so we can set them equal to each other and solve for x:

3x + 50 = 6x - 10

Adding 10 to both sides, we get:

3x + 60 = 6x

Subtracting 3x from both sides, we get:

60 = 3x

Dividing both sides by 3, we get:

x = 20

Therefore, the value of x is 20.
