A.) Population = The entire population of the country

Sample = 62,348 people in the state of Florida

B.) The approximations of the sample won't be very close to the approximations of the entire population because the survey was based on only one state and one model of health care delivery.

The information provided are

Number of people interviewed in the survey = 62,348  people

Location of the people surveyed = Florida

Goal of the survey = The effectiveness of the national healthcare

The number of females that visited a family doctor at least once in the past year = 83%

A plane is flying at an altitude of 17,000 feet. The angle of depression from the plane to the airport on the ground is 21°. Wha
viva [34]

Answer:

47,433.0 feet

Step-by-step explanation:

Using the SOH CAH TOA identity

Height of the plane = opposite = 17000feet

distance between the plane and the airport = hypotenuse = x

Angle of depression = 21 degrees

Since Sin theta = opp/hyp

Sin 21 = 17000/x

x = 17000/sin21

x = 17000/0.3584

x = 47,433.0

Hence the distance between the plane and the airport to the nearest 10th of a foot is 47,433.0 feet

Which of the following slopes of a line pass through points (1, -3) and (0, 2)?
Aloiza [94]

The slope of the line that passes through (1, -3) and (0, 2) is: B. m = -5.

<h3>What is the Slope of a Line?</h3>

Slope (m) = rise / run = change in y / change in x.

Given the points, (1, -3) and (0, 2):

Slope (m) = (-3 - 2)/(1 - 0)

Slope (m) = -5/1

Slope (m) = -5

Therefore, the slope of the line is: B. m = -5.
