Answer:
C. The manager visits a park and interviews people who were waiting to use the tennis courts.
Step-by-step explanation:
It's biased because the manager is clearly asking people only interested in tennis, not a clearly random sample.
Answer:
y = -4x - 32
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(8 - 4) / (-10 + 9)
4 / -1
= -4
So, the slope is -4. Plug in the slope and a point into y = mx + b, and solve for b:
y = mx + b
4 = -4(-9) + b
4 = 36 + b
-32 = b
Then, plug in the slope and y intercept into y = mx + b
y = -4x - 32 is the equation of the line
Answer:
B)8
Step-by-step explanation:
That is the right answer because when y=12, x=-6
12/-6 = -2
This means that x = y/-2
or y = x * -2
-4 * -2 = 8

Teddy =X
Dolls= 2x-14
2x-14+X=52
3X-14=52
Add 14
3X=66
Divide by 3
X= 22
Teddy are 22
Dolls 2(22)-14=30
