The average of a set of 4 numbers is 20. the average of another set of 6 numbers is 74. what is the average of the 10 numbers?

Let

x> the sum of the 4 numbers in the average 1

y> the sum of the 6 numbers in the average 2

we know that

x/4=20> x=20*4=80

y/6=74> y=6*74=444

so

The average of the 10 numbers is equal to

(x+y)/10=(444+80)/10> 52.4

therefore

the answer is

the average of the 10 numbers is 52.4

step-by-step explanation:

sorry no step by step

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
