Step-by-step explanation:
you subtract -4 by 7.
then you hav 5x=7
you divide 5x by 5 and seven by five so your x= that answer
then you put that number into the x in the second equtaion
then you subtract that number after multiplying the 6 by the number x equals
then you divide 2y by 2 and 22 by 2 and thats your y value
Answer:
Mean = 10.2
Standard deviation = 4.0
Step-by-step explanation:
The average age = mean age
Mean = (16 + 10 + 5 + 7 + 13)/5
Mean = 51/5 = 10.2
What is the standard deviation will be square root of variance
(16 - 10.2) + (10 -10.2) + (5-10.2) + (7-10.2)+( 13-10.2)
5.8 + 0.2 -5.2 - 3.2 + 2.8
Square each number
33.64 + 0.04 + 27.04 + 10.24 + 7.84
Variance = 78.8/5 = 15.76
Standard deviation = 3.969 = 4.0
