Triangle is dilated by a factor of i.e. each side multiplies to 0.25.
Side E'F' becomes 0.25 times the original length
The graph of y=sin(x-3π/2) is the graph of the y=sin(x) shifted in which direction
1 answer:
Answer:
units to the right
Step-by-step explanation:
If we have a parent function y = Sin(x), the function
- y = Sin(x-b) would be the parent shifted b units right
- y = Sin (x+b) would be the parent shifted b units left
The function given is
So from the rules, we can clearly say that it is parent function shifted RIGHT by units.
2nd answer choice is correct.

Answer:
There is not enough evidence to conclude that average starting salary for clerical employees in the state is less than $35,000 per year.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 35,000 dollars per year
Sample mean, = 34,700 dollars per year
Sample size, n = 100
Alpha, α = 0.10
Population standard deviation, σ = 3,500 dollars per year
First, we design the null and the alternate hypothesis
We use one-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to conclude that average starting salary for clerical employees in the state is less than $35,000 per year.
