Answer:
22.5
Step-by-step explanation:
SINCE Y VARIES DIRECTLY WITH X, WE USE THE FORMULA
y=kx; k representing the variable change, y= 7.5, x=5
> y=kx
>7.5= k(5) > 7.5= 5k
>k= 7.5/5 (divide to get the k)
k= 1.5
NOW REPLACE THE NEW VALUES OF X AND K AS THE VARIABLE CHANGE, TO FIND THE VALUE OF Y
>y=kx ; k=1.5 and x=15 y=?
>y= (1.5)(15)
>y=22.5
the value of y is 22.5 when x is 15

Step-by-step explanation:
mean=sum of observarion/totalno. 9f ovservation
