A data set has a RANGE of 24 and a MEAN of 104. If the data set contains three numbers and the highest number is 118, then what

s2008m [1.1K]

Answer:

highest number is 118

middle number is 100

lowest number is 94

Step-by-step explanation:

R=24---between high and low is 24 numbers

M=104---average of the three numbers

highest number is 118

therefore if you subtract 24 from 118 therefore the lowest number is 94

Then i used a mean calculator and went up from 95 to 100 before the means matched.

The density of a certain material is such that it weighs 9 kilograms for every 7 cubic feet of volume. Express this density in p

Vadim26 [7]

Answer:

1.641× 10^-3 pounds/ cubic inch

Step-by-step explanation:

Density= mass / volume

Mass of the material= 9 kilograms

Volume= 7 cubic feet

Density= 9/7= 1.286 kg/ ft^3

Density= 1.286 kg/ ft^3

To Convert to pounds per inch

1 kg/ ft^3 = 0.00128 pound / cubic inch

1.286 kg/ ft^3 = X pounds/ cubic inch

X=( 1.286 × 0.00128)

= 0.0016407087 pounds/ cubic inch

= 1.641× 10^-3 pounds/ cubic inch

Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch

Geometry math question no Guessing and Please show work thank you

hichkok12 [17]

we will use formula

$\theta=\frac{180(n-2)}{n}$

where

theta is angle

n is number of sides

we are given

n=15

we can plug it

$\theta=\frac{180(15-2)}{15}$

now, we can solve for theta

$\theta=\frac{60(15-2)}{5}$

$\theta=12*13$

$\theta=156$

so,

The sum of two books and a pencil is $6.00. The difference of cost between 3 books and 2 pencils is $ 2.00. Find the cost of a b

Gala2k [10]

Answer:

The book costs $2 and the pencil also costs $2.

Step-by-step explanation:

It is easy to get the value of the book and the pencil if we use algebraic expressions.

Let x be the cost of the book and let y be the cost of the pencil.

The sum of 2 books and a pencil is $6.00

2x + y = $6.00

The difference of cost between 3 books and 2 pencils is $2.00.

3x - 2y = $2.00

Step 1: Let's get the value of y first.

2x + y = 6

y = 6 - 2x

Step 2: Let's substitute the value of y and look for the value of x.

3x - 2y = $2.00

3x - 2(6-2x) = 2

3x - 12 + 4x = 2

7x = 12 + 2

7x = 14

x = $\frac{14}{7}$

x = $2 (this is the cost of the book)

Step 3: Let's substitute the value of x and look for the value of y.

2x + y = 6

2 (2) + y = 6

4 + y = 6

y = 6 - 4

y = $2 (this is the cost of the pencil)

Let's check:

2x + y = $6

2(2) + 2 = 6

4 + 2 = 6

6 = 6 (CORRECT)
