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
