Answer 1

Question

In a study of 100 new cars, 29 are white. Find p and q , where p is the proportion of new cars that are white.

Answer:

p = 0.29 and q = 0.71

Explanation:

Given

Total new cars = 100

White new cars = 29

Required

Determine p and q

From the question;

p represents white new cars

Hence;

`p = 29`

Note that;

`p + q = 100`

Substitute 29 for p

`29 + q = 100`

`29 - 29 + q = 100 - 29`

`q = 100 - 29`

`q = 71`

The proportion of p is calculate by dividing p by the total number of new cars (Same process is done for q)

For proportion of p

`Proportion,\ p = (p)/(new\ cars)`

`Proportion,\ p = (29)/(100)`

`Proportion,\ p = 0.29`

For proportion of q

`Proportion,\ q = (q)/(new\ cars)`

`Proportion,\ q = (71)/(100)`

`Proportion,\ q = 0.71`
