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

Graph -3x + 9y = -27​
Svetllana [295]

Answer:

Step-by-step explanation:

The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.

-3x + 9y = -27

9y = 3x - 27

y = 1/3x - 3

By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.

Helppppp<br> Find the value of x.<br> A. 176<br> B. 128<br> C. 256<br> D. 74
RSB [31]

Answer: Choice B) 128

Explanation:

We'll add up the given arc measures and then cut the result in half to get the angle formed by the intersecting chords (that subtend the arcs in question).

chord angle = (arc1+arc2)/2

x = (54+202)/2

x = 256/2

x = 128

You wish to take a flight from Nevada to New York. Use the point (-4, 0) to represent Nevada, and the (5, 2) to represent New Yo
Flauer [41]

Using proportions, it is found that the ordered pair that represents the location of the layover is given by: (2.75, 1.5).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the flight distance is partitioned in a ratio of 3:1, hence:

L - Nv = 3/4(Ny - Nv).

This ratio is applied for both coordinates, hence, for the x-coordinate:

x + 4 = \frac{3}/{4}(5 + 4)

x = \frac{27}{4} - \frac{16}{4}

x = \frac{11}{4}

x = 2.75.

For the y-coordinate:

y = \frac{3}/{4}(2 - 0)

y = \frac{6}{4}

x = 1.5.
