Find the point estimate of the proportion of people who wear hearing aids if, in a random sample of 493 people, 40 people had hearing aids.

0.0811

Step-by-step explanation:

In the absence of complete data , the sample proportion is considered as the  point estimate of the population proportion .

Given : Sample size of people : n= 493

Number of people had hearing aids : x = 40

Let p be the proportion of people who wear hearing aids.

Now , the sample proportion :

Thus , the point estimate of the proportion of people who wear hearing aids si 0.0811.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
