Answer:
The easiest way to figure this is to find P(no girls in 5 births) = (1/2)^5 = 1/32 -------------- The P(at least one girl in 5 births) = 1 - 1/32 = 31/32
Answer:
3
1
if your estimating to whole numbers the 3 1/8 is 3 and 1 2/5 is 1
Step-by-step explanation:
You just have to rearrange the formula.
So:
765 = 135 x m + 225
765 - 225 = 135 x m
540 = 135 x m
m = 540 / 135
m = 4
So four months.
Answer:
the length of the two equal sides: 8m
the length of the third side: 8m-4m=4m
8m×2+4m=20m
