Answer:

  • Zero

Step-by-step explanation:

Step 1. Find the mean

  • (- 9 - 18 - 16 - 13 - 14)/5 = - 14

Step 2. Find the deviation of each value from the mean

  • - 9 - (- 14) = 5
  • - 18 - (- 14) = - 4
  • - 16 - (- 14) = - 2
  • - 13 - (- 14) = 1
  • - 14 - (- 14) = 0

Step 3. Find the sum of the deviations

  • 5 - 4 - 2 + 1 + 0 = 0

Step 4. Find the MAD

  • 0/5 = 0

Find the discount price and subtract from the total to find the sale price.

To find the discount price, multiply 90 b 40% (convert 40% into decimal)

90 x 0.4 = 36

Next, subtract the discount from the total to find the sale price.

90 - 36 =  54

So, the sale price is <u>$54</u>.

when you reverse the digits in a certain two-diget number you increase it value by 27. What is the number if the sum of its digi
Fynjy0 [20]
The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is =  x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27    ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y

9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4

x=5-y
x=5-4=1

The number is: 10x+y=10(1)+4=14

Answer: the number is 14

A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a pers
tino4ka555 [31]

Answer:

19 situps

Step-by-step explanation:

Given that the regression equation to find a  a relationship between hours of TV watched per day (x) and number of situps a person can do (y) was done.

The result was

y = ax+b

y = -1.23x+22.738\\

Correlation coefficient = 0.865

To predict the number of situps a person who watches 3 hours of TV

y = -1.23(3)+22.738

= 19.048

Approximately 19 situps.

Aneli [31]

Answer:

Smallest: 15,840 ft

Largest: 16,896 ft

Step-by-step explanation:

1 mi = 5,280 ft

Setup proportion to solve for the <u>smallest</u>:

\frac{1mi}{5,280ft} =\frac{3mi}{xft}

Do butterfly method and you should get this:

xft=3(5280)\\x=15,840ft

Setup proportion to solve for the <u>largest</u>:

\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}

Butterfly method:

xft=3.2(5280)\\x=16,896ft
