C. an= -3+ (n - 115)
Step-by-step explanation:
hope it help
I believe the answer is 18, because 5x3=15, so we can only assume that N is 6x3=18.
Answer:
x ≤ 8
Step-by-step explanation:
Given
2x - 4 ≤ 12
Isolate the term in x by adding 4 to both sides
2x ≤ 16 ( divide both sides by 2 )
x ≤ 8 ← is the solution
Answer:
it is not necessary to confirm that the sample data appear to be from a population with a normal distribution;
D. Because the sample size of 50 is greater than 30, it can be assumed that the sample mean is from a population with a normal distribution
Step-by-step explanation:
Normal distribution which is otherwise known as the Gaussian distribution, it is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
The arithmetic mean or average; is the sum of a collection of numbers divided by the total numbers in the collection.
We need 75 quarts of 3% butterfat milk. How much of 2% and 5% do we need to mix? (t = 2% and f = 5%)
A) t + f = 75
B) .02 t + .05 f = (.03 * 75)
B) .02 t + .05 f = 2.25
Solving for t and f:
t = 50 quarts of 2 % and
f = 25 quarts of 5%
Double-Check
50 * .02 = 1 quart of buttermilk
25 * .05 = 1.25 quarts of buttermilk
2.25 quarts divided by 75 quarts = 3 % buttermilk
