Answer:
Given:
Null hypothesis: the average salary for new college graduates with a job is $50,556.
Alternative hypothesis: the graduates from a university earn more than that average.
Using the z-test:
=> Calculate the value of test statistic:
t = (mean of sample - mean of null hypothesis)/(std/sqrt(number of sample)
= (53200 - 50556)/(10200/sqrt(100))
= 2.592 > 1.645
=> Reject the null hypothesis, their graduates earn more than average
Hope this helps!

Answer:
(0, - 4 )
Step-by-step explanation:
under a counterclockwise rotation about the origin of 180°
a point (x, y ) → (- x, - y ), hence
C(2, 4) → (- 2, - 4)
A translation of 2 units to the right means add 2 to the original x- coordinate while the y-coordinate remains unchanged.
(- 2, - 4 ) → (- 2 + 2, - 4 ) → (0, - 4 )

Just Quick REVIEW On Formula:
- Curved Surface Area (CSA)=2πrh
- Total Surface Area (TSA)=2πr(r+h)
- Volume (V)=πr2h
- Here, we have Radius(r)=3and Height(h)=10(Given)
- Volume=πr2h
- =π⋅32⋅10
- =282.7433
