The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

<h3>What is relative frequency?</h3>

The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.

Given information-

The card is selected random from the deck of cards.

Total number of trails is 40.

It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.

As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

$f_r=\dfrac{11}{40}\\f_r=0.3$

In the percentage from,

$f_r={0.3}\times100\\f_r=30$

Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

Write and solve an equation to find your final score. Use x to represent your final score.

attashe74 [19]

Let your final bowling score be x. It is 14 pins less than your friends final score. Your friends final bowling score is 105. Then x is 14 pins less than 105.
1 way: This means that 105 is greater than x by 14. Mathematically,
105-x=14,
-x=14-105,
-x=-91,
x=91.
2 way: When you add 14 to x, you'll get 105.
x+14=105,
x=105-14,
x=91.
Answer: Your final score is 91.
