A psychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test. The scores

are from 0 to 100, with higher scores meaning more stress. She finds that there is a negative linear association between w and t that is best modeled by the equation t=−2.5w+48.1 .
What is the meaning of 48.1 in this equation?

A. The people who walked each day had an average score of 48.1 on the stress test.

B. The model predicts that a person who does not walk each day will score about 48.1 on the test.

C. The people in the study walked an average of 48.1 minutes each day.

D. For each additional minute spent walking, the model predicts that a person's score on the stress test will go down by about 48.1 points.

he Statue of Liberty is approximately 305 feet tall. If the angle of elevation of a ship to the top of the statue is 22.9 degree
Andru [333]

Answer:

is at a distance of 722 feet

Step-by-step explanation:

we have the angle that forms between the water and the imaginary line between the ship and the tip of the statue

we have the statue height that would be the opposite leg to our angle and we want to know the distance of the ship to the statue that would be the adjacent leg

we see that it has (angle, adjacent, opposite)

well to start we have to know the relationship between angles, legas and the hypotenuse

a: adjacent

o: opposite

h: hypotenuse

sin α = o/h

cos α= a/h

tan α = o/a

it's the tangent

tan α = o/a

we replace the values ​​and solve

tan α = o/a

tan 22.9 = 305/a

a = 305/tan22.9

a = 305/0.4224

a = 722

is at a distance of 722 feet
