<u>Answer:</u>

The correct answer option is \frac { 4 } { 4 9 }.

<u>Step-by-step explanation:</u>

We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).

Total number of days in a week = 7

Number of days in weekend = 2

Probability of being born on weekend = \frac { 2 } { 7 }

P (both parents were born on weekend) = \frac{2}{7} \times \frac{2}{7} = 4/49

1. Calculate the area of the<br> figure below. Round to the<br> hundredths place when<br> necessary.
a_sh-v [17]

Answer:

The area is 88.39 cm

Step-by-step explanation:

Here, we want to find the area of the semicircle given that the diameter of the semi circle is 15 cm

We start by getting the radius

Mathematically r = D/2

= 15/2 = 7.5

Area of semicircle is area of circle/2

= (pi * r^2)/2

= (22/7 * 7.5^2)/2 = 88.39 cm
