Additionally, the parabola is moved 1 unit towards positive Xs, so —(x—1)²
and it's one unit up so —(x—1)²+1

Answer:
True
Step-by-step explanation:
Change the Whole Number to a fraction, or just plug it in a claculator 7-(4/24)= 6.8333333333.
if you change the whole number to a fraction you would have to multiply 7 by 24 to have a common denominator which would give you 168/24 so

Answer:
We conclude that the mean number of residents in the retirement community household is less than 3.36 persons.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 3.36
Sample mean, = 2.71
Sample size, n = 25
Alpha, α = 0.10
Sample standard deviation, s = 1.10
First, we design the null and the alternate hypothesis
We use One-tailed(left) t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and fail to accept it.
Thus, we conclude that the mean number of residents in the retirement community household is less than 3.36 persons.
