we know that
<u>The correlation coefficient</u> is a number between 
and 
that represent the linear dependence of two variables or sets of data
Using the function CORREL in a excel tool, calculate the correlation coefficient (r)
see the attached table
the correlation coefficient for the data in the table is equal to 
therefore
<u>the answer is</u>
X/15=4/16 def of similar triangle by AAA
x = 60/16=5/2
2/35, just ask your calculator what is one seventh of two and one half.<span />
Answer:
the football team drank 10 gallons of water
Step-by-step explanation:
if the football team drank 1/3 less than 15, 1/3 of 15 is 5 so you would then subtract 5 from 15 and you get 10
19/38 and 15/18
Explanation:
19/38 can be reduced as there is a factor other than 1 that can divide without a remainder. Factor is 19
It can still be reduced because 19*2 = 38
19/38 = 1/2
10/19 cannot be reduced as there is no factor other than one to divide without a remainder
21/34 cannot be reduced as there is no factor other than one to divide without a remainder
15/18 can be reduced as there is a factor other than 1 that can divide without a remainder.
The factor is 3
15/18 = 5/6
Fraction that has not been reduced to simplest form are 19/38 and 15/18
