Find the Mean, Median, Mode, and Range for the following numbers: 18, 10, 9, 15, 18

A. Mean: 14 Median: 15 Mode: 18 Range: 9
B. Mean: 15 Median: 17 Mode: 18 Range: 7
C. Mean: 14 Median: 18 Mode: 15 Range: 8
D. Mean: 16 Median: 15 Mode: 9 Range: 18

Answers

Answer 1
Answer is A.

To find the mean, you add, 9+10+15+18+18 and you get 70. You then divide them by 5 because that’s how many numbers you have and you get 14.

To find median, you rearrange the numbers from largest to smallest, (9,10,15,18,18) and the number in the middle is 15. That is your median.

The mode is 18 because you have more than one of it.

And the range, 18-9=9. You subtract the smallest number from the biggest and you get 9.

The rectangular prism and rectangular pyramid below have the same volume. Determine the value of x, the length of the prism.

Answers

ANSWER

[tex]x[/tex]= 9 [tex]in[/tex]

EXPLANATION

The volume of a rectangular prism is given by the formula,

[tex]V[/tex]= [tex]l[/tex] x [tex]b[/tex] x [tex]h[/tex]

We substitute the dimensions to obtain,

[tex]V[/tex]= 6 x 3 x 12 [tex]in^{3}[/tex]

The volume of the rectangular pyramid is,

[tex]V[/tex]= [tex]\frac{1}{3}[/tex] x 6 x 12 x [tex]x[/tex] [tex]in^{3}[/tex]

Equating the two values gives,

[tex]\frac{1}{3}[/tex] x 6 x 12 x [tex]x[/tex] = 6 x 3 x 12

We divide through by 6×12 to get,

[tex]\frac{x}{3}[/tex] = 3

We solve for x to obtain,

[tex]x[/tex] = 3 x 3

[tex]x[/tex] = 9 [tex]in[/tex]

Hope this helps! Happy Monday!

if Sonja makes $2100 interest after investing $15,000 at 2.8%, how many years did she invest for?

Answers

Answer:

Sonja invested for 5 years.

Step-by-step explanation:

First you have to find how much money she gets in one year.

To do this you would have to multiply 15,000 and 2.8.

15,000 x 2.8 = 42000

You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.

This gives you 420.

To find how many years it takes for her to make $2100 you have to divide

2,100/420.

This gives you 5, which means that she invested for 5 years.
