Answer:
We accept the null hypothesis and conclude that voltage for these networks is 232 V.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 232 V
Sample mean,
= 231.5 V
Sample size, n = 66
Sample standard deviation, s = 2.19 V
Alpha, α = 0.05
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,

We accept the null hypothesis and conclude that voltage for these networks is 232 V.
Answer:
im pretty sure a, b, and d
Step-by-step explanation:
the domain is 3, 0 and for every y value the x value is 3
Answer:
y=2x+35
Step-by-step explanation:
so y is what it's equal too so you put y=
then since its $2 every mile you put them next to eachother like
2x so y=2x
then there is just a plain fee of $35 so you add that to the equation which is what makes it look like
y=2x+35
Hope this helps!! :D
