the mean (average) of the data set below

2/4, 18/5, 28/10, 5/20

We are given with 4 fraction

to find mean , we add all the fractions and divide by 4

Lets add all the fractions

Make the denominators same

LCM is 20

Try to get 20 in the denominator

Now we divide by 4

idk

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
