Question

a hockey player scores a goal on 35% of her attempts. Out of her next 20 attempts, How many times can you expect the player to score a goal?

Answer 1

A hockey player scores a goal on 35% of her attempts, then you can use the proportion:

20 attempts is 100%

x goals is 35%.

Mathematically you can write that
`(20)/(100) =(x)/(35)`.

Therefore,
`x=(20\cdot 35)/(100) =(700)/(100)=7`.

If she has 20 attempts, then you can expect that the player score a goal 7 times.
