Answer:
A. The temperature outisde and the number of people swimming at the beach.
Step-by-step explanation:
As the temperature decreases the number of people swimming will also decrease. This will create a negative correlation between the two factors.
Answer:
0.35, 0.40
Step-by-step explanation:
A(n) = –3 • 2⁽ⁿ⁻¹⁾
for n = 1 , A₁ = -3.(2)⁰ = -3
for n = 2 , A₂ = -3.(2)¹ = -6
for n = 3 , A₃ = -3.(2)² = -12
for n = 4 , A₄ = -3.(2)³ = -24
...........................................
for n = 8 , A₈ = -3.(2)⁷ = -384
As you can see, every time x increases by 2, y decreases by 5.
So, we have
(not sure if this is right but)
x (to the 2nd power) + y (to the 2nd power) = cos (90) (to the 2nd power)
