Part B: Absolute Deviation= 0  

shown work for part B:      (subtract each number by the mean)

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

(then divide sum by mean) 0 divided by 8 = 8

The number of storybooks owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8. The mean is 8 and Absolute Deviation= 0.

How to find the mean value of a data set?

The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The number of storybooks owned by eight classmates is shown below:

8, 9, 9, 7, 8, 6, 9, 8

Part A:

[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]

Therefore, The mean is 8

Part B: Absolute Deviation= 0  

subtract each number by the mean

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

(then divide sum by mean) 0 divided by 8 = 8

Evaluate p/n if n = 2 and p = -8

Answers

Answer:

-4

Step-by-step explanation:

-8/2= -4

Answer:

-1/4 or -0.25

Step-by-step explanation:

n=2 and p=-8

substitute p as the numerator and n as the denominator in the fraction

2/-8 simplifies to 1/-4, the sign moves to the front of the fraction because any positive number divided by a negative number will be negative and it is common practice, so the answer is -1/4.

-1/4 is equal to -0.25 in decimal. -0.25 is 1/4 of -1.

find the volume of the cone using the given formula

Answers

Answer:

I believe your answer would be

Step-by-step explanation:

Using that formula, we can substitute in the values we need that are given to us in the question:

h = 12

r = 4

Now we need to use the formula.

V = 1/3 (pi) (4²) (12)

First lets do the exponent.

4² = 16

V = 1/3 (pi) (16) (12)

Now lets do pi × 16.

pi × 16 = 50.2654824574.

Now we have:

V = 1/3 (50.2654824574) (12)

Multiply 50.2654824574 and 12.

50.2654824574 × 12 = 603.185789489

Now all we have:

V = 1/3 (603.185789489)

Multiply them.

V = 201.06192983

So, your answer is V ≈ 201.06192983, or 201.

Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks. How many large trucks does the company have?

Answers

Answer: 9

Step-by-step explanation:

The company has a total of 3 big trucks.

What is algebraic expression?

An algebraic expression is a combination of terms both variables and constants. We can write the examples of algebraic expression as -

2x + 3y + 5

5x + 4y + 1

Given is that Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks

We can write the system of equations as -

s + b = 15

6s + 12b = 108

6(15 - b) + 12b = 108

90 - 6b + 12b = 108

18 = 6b

b = 4

Therefore, the company has a total of 3 big trucks.

if ben makes $35.00 per hour and then gets a ten percent raise what is his new salary. Show your work

Answers

Answer:

$38.50 per hour

Step-by-step explanation:

10% = 0.1

0.1 × 35.00 = 3.50

35.00 + 3.50 = 38.50

Answer:

The answer is $38.50

Step-by-step explanation:

35 x 0.1 = 3.5 (0)

35 + 3.50 = 38.50

The reason we do 0.1 is because 10% written in decimal form is 0.1 and since 35.00 is a decimal we made the percent into a decimal to make it even.
