Answer:

b. 0.055

Step-by-step explanation:

The point estimate of the proportion of people who wear hearing aids is

The number of people in the sample who wear hearing aids divided by the total number of people in the sample.

In this problem, we have that:

Sample of 855.

47 people in the sample had hearing aids.

47/855 = 0.0549

Rounding up

0.055

So the correct answer is:

b. 0.055

Ln(x + 1) − ln(2) = 1
KonstantinChe [14]

Answer:

The answer to your question is: x = 4.44

Step-by-step explanation:

Data

                                          ln(x + 1) − ln(2) = 1

                                          In (x + 1)/2 = 1

                                          (x + 1) / 2 = e¹      

                                          x + 1 = 2 (2.7183)

                                          x = 5.44 - 1

                                          x = 4.44

H : because each square contains 100 blocks so the two boxes would be 200 together and as you see one square has all blocks shaded ( 100% ) and then has another 100 block with only 40% shaded in 100% + 40% = 140%
