Based on the NYC Department of Health Community Health Survey in 2010, a 95% confidence interval for the proportion of New Yorke

rs who were tested for HIV in the past 12 months is (29.9%, 32.9%). If the population size is 6 million in 2010, with 95% confidence, we know that at least how many New Yorkers were tested for HIV within the past 12 months?

Answer:

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

Step-by-step explanation:

The lower bound of the confidence interval is 29.9%.

So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.

Out of 6 million, that is:

0.299*6000000 = 1,794,000

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

Write three different equations that have x=5 as a solution
svlad2 [7]

Answer: The three different equations will be

x+3=8\\\\2x-8=2\\\\4x-4=16

Step-by-step explanation:

We have to write three equation that have x = 5 as a solution:

1) First equation will be

x+3=8\\\\x=8-3\\\\x=5

2) Second equation will be

2x-8=2\\\\2x=8+2\\\\2x=10\\\\x=\frac{10}{2}\\\\x=5

3) Third equation will be

4x-4=16\\\\4x=16+4\\\\4x=20\\\\x=\frac{20}{4}\\\\x=5

Hence, the three different equations will be

x+3=8\\\\2x-8=2\\\\4x-4=16

IT'S URGENT PLEASEE<br><br> What is the slope of a line perpendicular to the line 2y = 3x - 10?
belka [17]
<h3>Answer:  perpendicular slope is -2/3</h3>

=================================================

Work Shown:

Solve the given equation for y

2y = 3x - 10

y = (3x-10)/2 ..... divide both sides by 2

y = (3x)/2 - 10/2

y = (3/2)x - 5

The equation is in y = mx+b form with m = 3/2 as the slope.

The perpendicular slope is -2/3 because we flip the fraction and the sign from positive to negative.

Note how multiplying the original slope 3/2 and the perpendicular slope -2/3 leads to -1

(3/2)*(-2/3) = -1

This is true for any pair of perpendicular lines, assuming neither line is vertical.
