What is the possibility of having 3 children that are all boys

1 answer:

6 0

We have 3 children, with each one possibly being a boy or a girl. And so for each child, the probability of being a boy is 1/2 same with a girl so

1/2^3 = 1/8

so it's 1/8 chance of it being a boy.

A square of the side lenght of 6cm has the same area as this rectangle . find the perimeter of the rectangle.

Aleksandr-060686 [28]

Answer:

The perimeter of the rectangle is 26 cm

Step-by-step explanation:

First find the area of the square by multiplying 6 by itself

A = 6 cm * 6 cm = 36 sq cm

Since the rectangle has the same area as the square, we can say that w * 9 = 36 sq cm

w * 9 = 36

Divide both sides by 9 to isolate the variable, w

w * 9 / 9 = 36 / 9

w = 4 cm

The width of the rectangle is 4 cm so now we just use that to find the perimeter of the rectangle

P = 2(9) + 2(4) = 26 cm
