Answer:

n = 24

p(a) = 10/24

p(b) = 15/24

[ p(a) + p(b) - [p(a) ×p(b)] ] -1 = answer

[ 35/24 - 6/24 ] -1 = 39/24 - 24/24 = 5/24

<h3>Answer: 6</h3>

=================================================

Explanation:

There are 24 people total and 18 of them study at least one subject. So that must mean 24 - 18 = 6 people do not study any of the subjects mentioned.

The values of 10 and 15 aren't used at all.

A rectangle has an area of 69.6m^2.

omeli [17]

Answer: The perimeter of the rectangle is 53.8. One side is 24, and the other is 2.9.

Step-by-step explanation:

First you need to divide 69.6 meters by 2.9. This gives you 24 as the other side of the rectangle(remember that the area of a rectangle is $lw$ ). Next you multiply 2.9 x 2. This gives you 5.8, then you multiply 24 by 2. This gives you 48. You add the two values together,and you get the perimeter of the rectangle as 53.8.
