Answer: D: The model predicts that a person who does not walk each day will score about 48.1 on the test.
Step-by-step explanation:
Given: A psychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test.
She finds that there is a negative linear association between w and t that is best modeled by the equation 
.
When we put w=0 minutes, t=48.1
It implies that if any patient doesn't walk will score 48.1.
Hence, the model predicts that a person who does not walk each day will score about 48.1 on the test.
I have not done this mathematically but I think it would be a parallelogram. I just visualised the points and it looks like a parallelogram on a slant. Let me know if you need a more mathematical answer :)
Answer:
20
Step-by-step explanation:
Assuming that the equation is x³ = 64, that can be solved by putting cube root on both sides like so: ∛(x³) = ∛64, which simplifies to <em>x = 4</em>.
Plugging that into our expression gives us <em>4² + 4</em>, which is 20.
Answer:
4.243
step by step explanation:
Answer:
Amount saved = $17.04
Step-by-step explanation:
An item you want is regularly $56.23, but is on sale for $40 this week
Original amount is $56.23
tax is 5%, tax amount is 
Original cost with tax is 
Sale amount is $40
tax is 5%, tax amount is 
sale cost with tax is
