Answer: approximately normal
Step-by-step explanation:
1/2 Thinking about population shape and sample size
When a population is normally distributed, the sampling distribution of the sample mean x will also be normal regardless of sample size.
Since the distribution of distances is normal, the sampling distribution of the sample mean distance will also be normal.
2/2 Answer
The sampling distribution of the sample mean distance will be approximately normal.
Answer: 1,225 ≤ 2t - 500
Step-by-step explanation: t = tickets
80/10=8 packages of plates
80/16=5 packages of napkins
80/8=10 packages of cups
Answer:
(1, 2) and (-1, -2)
Step-by-step explanation:
Since y = 2x, the first blank tells you
2x = 2
x = 1
____
Since the variables are squared, a negative solution is as good as a positive solution, so x = -1 and y = -2 will also work.
