Answer:
1.6 dozen cookies per an hour
Step-by-step explanation:
2 1/2 divided by 2 1/2 gives you 1 hour and 4 divided by 2 1/2 gives you 1.6 dozen cookies
Answer:
We conclude that the calibration point is set too high.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1000 grams
Sample mean,
= 1001.1 grams
Sample size, n = 50
Alpha, α = 0.05
Population standard deviation, σ = 2.8 grams
First, we design the null and the alternate hypothesis

We use One-tailed(right) z test to perform this hypothesis.
Formula:

Putting all the values, we have

Now, 
Since,

We reject the null hypothesis and accept the alternate hypothesis. We accept the alternate hypothesis. We conclude that the calibration point is set too high.
Answer:
B. The absolute value parent function
Step-by-step explanation:

Referred to as absolute value, the value inside the bars is measured in terms of its distance from 0. Therefore:

In essence, a negative value within the bars becomes positive, while a positive value remains positive.
So the expression is:

You can combine like terms, which are terms that contain the same variables raised to the same power. That means you can combine the two

.

The other terms can't be combined.
Your final answer should be

.
