Each peach costs $0.56 and the equations used to solve that is where x is the cost of 1 peach.
Step-by-step explanation:
Step 1:
It is given that all the peaches weigh the same and that 4 peaches weigh 1 pound.
Assume that each peach costs x.
So the cost for 4 peaches is given by
Step 2:
The cost of 1 pound of peaches is given as $2.24.
1 pound of peaches
So
So each peach costs $0.56.
Answer:
Mean 160
Standard deviation 2.63
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation
In this problem, we have that:
Find the mean and standard deviation of the sampling distribution of sample means with sample size n = 58.
Mean 160
Standard deviation
