Hence,
is divisible by
and the correct option is (A).
Work shown above! Answer would be 110 degrees!
Nuke caught the ball after it was thrown 198ft
Ok so mean means average so exmple
mean of 1,2,3+5 would be (1+2+3+5)/4
(sum of terms)/(number of terms)=mean so
number of terms=5 since 5 oranges
sum=(46+39+53+61+49)
so mean=(46+39+53+61+49)/5=248/5=49.6
so the answer would be 49.6 (estimateed to be 50)
