Answer:

10 times

Step-by-step explanation:

This is a ratio problem.

We can see from the chart that out of the 36 possible choices, rulling a sum of three is 2. Therefore that fraction would be 2/36, about two times out of the thirty six times rolling would be a three.

Now, they're asking us how many times the sum will be three when the dice are rolled not just 36 times but 180. Therefore we can set up a ratio. We need to do this to find out how many times Tamara can expect to roll a three when she's rolling a total of 180 times.

2/36 = X/180

To solve for X we multiply 180 on each side:

(2/36)(180)=10=X

Therefore, when Tamara rolls the dice 180 times, she can expect the sum to be three 10 times.

Answer:

The answer is 43u – 33v

Step-by-step explanation:

5u – 8v + 9(2u – 3v) -4(2v – 5u)

5u – 8v + 18u – 27v – 8v + 20u

5u + 18u + 20u – 8v – 27v – 8v

43u – 33v

Thus, The answer is 43u – 33v

Answer:

Measures of variability would describe how the central tendency is influenced by the data. Since the central tendency is the tendency of data values to cluster around some central value, then measures of variability would show how strong the central tendency is.

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.

Answer:

1. 3/10 is equal to .3 or 30%

2. 7/10 is equal to .7 or 70%

3. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = (30 +20) you can distribute the value outside of the parentheses to the values inside.

Answer:3/10 is 0.3 7/10 is 0.7 2/10 is 0.2

n math, distribution (also called the distributive property of multiplication over addition) allows you to split a large multiplication problem into two smaller ones and add the results to get the answer.

If you’ve ever tried to carry a heavy bag of groceries, you may have found that distributing the contents into two smaller bags is helpful. This is similar to how the distributive property works for multiplication.

Here’s an example: multiply 17 101 using the distributive property.

1. Simplify the numbers.

In this example, 101 = 100 + 1, so:

17 101 = 17 (100 + 1)

Split the problem into two easier problems.

Take the number outside the parentheses, and multiply it by each number inside the parentheses, one at a time.

= (17 100) + (17 1)

3. Add the products.

At this point, you may be able to solve the two multiplications in your head and then add them up easily:

= 1,700 + 17

= 1,717

Answer: a. 5

Since the angle is right, we know it is equal to 90 degrees.

Using the information provided, we can set up an equation.

50 + 5x + 15 = 90

Simplifying the equation, we get:

5x + 65 = 90

Subtracting 65 from both sides, we get:

5x = 25

Dividing both sides by 5, we get:

x = 5

Answer:

? Did you finish asking it...............?

Step-by-step explanation:

Answer:

The constant of proportionality is 12.

Step-by-step explanation:

Let's take a look at the formula give to us:

48=4k

First, we have to isolate the variable, K, by dividing 4 on both sides.

48/4=4/4 k

48/4=12

12=k

We can check the answer by plugging it back into the equation:

12*4=48

48=48

Hence, the variable k equals 12.

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

Answer:

Amir will get 160/13 or 12 \(\frac{4}{13}\) and Isaac will get 20 \(\frac{9}{13}\)

Step-by-step explanation:

Lets say that the ratio is \(5x:8x\). Then, let's put this into an equation:

\(5x+8x=32\)

Then, if we solve, we get:

\(13x=32, x=\frac{32}{13} \text{ or } 2\frac{6}{13}\\\)

Then, we know that Amir's share is \(5x\), so \(\frac{32}{13}\cdot5=160/13 \text{ or } 12 \frac{4}{13}\).

Then, Isaacs share is \(8x\), so \(8\cdot\frac{32}{13}=20\frac{9}{13}\)

Hope it helps!!

Answer:

Amir = 12 and Isaac = 20

Step-by-step explanation:

Given

\(Amir : Isaac = 5 : 8\)

\(Munchkins = 32\)

Required

Amount of munchkins given to each person

For Amir, the amount is calculated as:

\(Amir's = \frac{Amir}{Amir + Isaac} * Munchkins\)

\(Amir's = \frac{5}{5+8} * 32\)

\(Amir's = \frac{5}{13} * 32\)

\(Amir's = \frac{5 * 32}{13}\)

\(Amir's = \frac{160}{13}\)

\(Amir's \approx 12\)

For Isaac, the amount is calculated as:

\(Isaac's = \frac{Isaac}{Amir + Isaac} * Munchkins\)

\(Isaac's = \frac{8}{5 + 8} * 32\)

\(Isaac's = \frac{8}{13} * 32\)

\(Isaac's = \frac{8 * 32}{13}\)

\(Isaac's = \frac{256}{13}\)

\(Isaac's \approx 20\)
