Answer:
This would be test of independence because it contain only one sample test
Step-by-step explanation:
Test of independence determine two factors are independent or not
For example
if we do a test of independence
null hypothesis : H 0: Being a cell phone user while driving and receiving a speeding violation are independent events. If the null hypothesis were true, we would expect about 28 people to use cell phones while driving and to receive a speeding violation.
Therefore in the given question Each respondent answer that it might be in "Right Direction " or "Wrong Direction".
So it is a independent test.
Answer:
B, 19
Step-by-step explanation:
To find f(2), we simply plug in 2 for x in the equation: 
We have: 
Thus, the answer is B, 19.

Answer:
coordinates of its image
A' = ( -4, -1)
B' =( -3, -3)
C' = ( 0, 2)
Step-by-step explanation:
Reflect in y-axis means mirror it's points in the y -axis.
This means that the x coordinate of each point, changes only. Any mirrored point in the y-axis, will change only, by multiplying the x-coordinate by -1.
(Remember, zero multiplied by -1 remains 0).
Given are these points A, B, and C.
A = (4, -1)
B = (3,-3)
C = (0, 2)
After mirroring in the y- axis you get:
A' = ( -4, -1)
B' =( -3, -3)
C' = ( 0, 2)
Answer:
y = -7
Step-by-step explanation:
y = 1/2x
x = -14 (given)
y = 1/2 × (-14)
= -7
