Answer:

-3

Step-by-step explanation:

\(\frac{\sqrt[3]{81} }{\sqrt[3]{-3}}\\\)

the index of both the numerator and denominator are "3", so they cancel each other out:

\(\frac{\sqrt{81} }{\sqrt{-3}} \\=\frac{9}{-3}\\ =-3\)

Answer:

x = 29

y = 93

Step-by-step explanation:

Angles 1 and 3 are vertical angles and congruent.

3x = 87

x = 29

Angles 2 and 3 are a linear pair and supplementary, so their measure have a sum of 180°.

y + 87 = 180

y = 93

Answer:

The value of x = 29.

The value of y = 93.

Answer:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Step-by-step explanation:

Answer:

You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.

Step-by-step explanation:

To determine the value of a variable expression: Replace the values for the variables in step 1.

2. List the grouping symbols, starting with the symbols closest to the center.

3. Determine the exponentiation rules and use them to simplify.

4. Evaluate. Use x to evaluate the expression.

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:

Step-by-step explanation:

Given that,

→ Magazine = $5

→ Total cost = $25

→ 1 eraser = x

The equation will be,

→ 4x + 5 = 25

Now the value of x will be,

→ 4x + 5 = 25

→ 4x = 25 - 5

→ x = 20/4

→ [ x = $5 ]

Hence, value of x is $5.

6. correct

Step-by-step explanation:

P(parenthesis) E(exponents) M(multiplication) D(division) A(addition) S(subtraction)

You first solve what is in the parenthesis (if there is any) than make your way down this list IN ORDER until you hit subtraction.

1.

\((8+7)/3=5\\\\(15)/3=5\\5=5\)

2.

(4 × 5) − 3 = 8

Parenthesis first

(20)-3=8

subtract

17=8

3.

(4 × 5) − 3 = 17

Do what is in parenthesis first

(20)-3=17

subtract

17=17

4.

14 − 7 × 2 = 0

Multiply 7*2 first

14-14=0

subtract

0=0

5.

14 − 7 × 2 = 14

Multiply 7*2 first

14-14=14

subtract

0=14

6.

12 + (7 + 9) = 28

Parenthesis first

12+(16)=28

Add

Answer: 76m

Step-by-step explanation:

First, start by splitting the figure into 2 smaller rectangular prisms; this can be done vertically or horizontally. I'll solve both ways so you can understand better.

Method 1: Splitting the figure into 2 rectangles vertically

The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the width (2m) by the length (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 5m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 5m (the height), and the answer is 40m.

Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 4m and you can figure out the width by subtracting 5m - 2m which gives you 3m. Now you know your base which is 4m. To solve for the height you must again subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 4 X 3 X 3. The volume of rectangular prism 2 should come out to be 36m.

The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 40m + 36m = 76m.

Method 2: Splitting the figure into 2 rectangles horizontally

The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the length (2m) by the width (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 2m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 2m (the height), and the answer is 16m.

Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 5m and the given width is 4m. Now you know your base which is 4m. To solve for the height you must subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 5 X 4 X 3. The volume of rectangular prism 2 should come out to be 60m.

The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 16m + 60m = 76m.
