Graph the image of rectangle STUV after a reflection across the line x = -2
1 answer:
Answer: see image
<u>Step-by-step explanation:</u>
Draw line x = -2. Count how many units away each point is from line x = -2 and create the new points the same number of units away from line x = -2 but in the opposite direction.
S is 5 units to the right of x = -2. The new point S' is 5 units to the left of x = -2.
T is 6 units to the right of x = -2. The new point T' is 6 units to the left of x = -2.
U is 6 units to the right of x = -2. The new point U' is 6 units to the left of x = -2.
V is 5 units to the right of x = -2. The new point V' is 5 units to the left of x = -2.

Answer:
The difference in the sample proportions is not statistically significant at 0.05 significance level.
Step-by-step explanation:
Significance level is missing, it is α=0.05
Let p(public) be the proportion of alumni of the public university who attended at least one class reunion
p(private) be the proportion of alumni of the private university who attended at least one class reunion
Hypotheses are:
: p(public) = p(private)
: p(public) ≠ p(private)
The formula for the test statistic is given as:
z= where
- p1 is the sample proportion of public university students who attended at least one class reunion (
)
- p2 is the sample proportion of private university students who attended at least one class reunion (
)
- p is the pool proportion of p1 and p2 (
)
- n1 is the sample size of the alumni from public university (1311)
- n2 is the sample size of the students from private university (1038)
Then z= =-0.207
Since p-value of the test statistic is 0.836>0.05 we fail to reject the null hypothesis.
There are 23535820 combinations that can be made of 35 calculators taken 8 at a time.
