Answer:
XY = 23.3 ft
Step-by-step explanation:
It helps if you can draw yourself a picture.
You are given right triangle with the adjacent side of the 9° angle and you are looking for the hypotenuse.
The cos of an angle = adjacent side/hypotnuse
Let h = XY
Then cos 9 = 23/h
h cos 9 = 23
h = 23/cos 9
h = 23.3 ft.
I don’t understand your question.Did the problem ask you to draw a diagram?
Answer:
Strong positive correlation
Step-by-step explanation:
The closer the value of ρ is to +1, the stronger the linear relationship. For example, suppose the value of oil prices are directly related to the prices of airplane tickets, with a correlation coefficient of +0.8.

Step-by-step explanation:
Answer:
y = (x - 8)² - 47
Step-by-step explanation:
x² - 16x + 17 = 0
x² - 16x = -17
(-16) / 2 = -8
-8² = 64
x² - 16x + 64 = -17 + 64
(x - 8)² = 47
y = (x - 8)² - 47
