Answer:
There is a 82% probability that th esample mean annual sales per square foot is at least $384.
Step-by-step explanation:
We have a population with mean 390 and standard deviation 45.83.
Samples of size n=49 are taken.
The parameters of the sampling distribution are:

First, we have to calculate the z-score that satisfies:

This z-score, looked up in a standard normal distribution table, is z=-0.915.
Then, we can calculate the sample mean as:

There is a 82% probability that th esample mean annual sales per square foot is at least $384.
It would be 2. Have a nice day.
Isolate the p. First, add 16 to both sides
3p - 16 (+16) < 20 (+16)
3p < 36
Next, isolate the p. Divide 3 from both sides
3p/3 <36/3
p < 12
p < 12 is your answer
hope this helps
Answer:
I think box #1 doesnt't belong because it say spend $100 and get $10 off
Step-by-step explanation:
Answer:
(2w-1)/5+w+2=2w
We simplify the equation to the form, which is simple to understand
(2w-1)/5+w+2=2w
Reorder the terms in parentheses
( + 0.4w-0.2)+w+2=2w
Remove unnecessary parentheses
+ 0.4w-0.2+w+2=2w
We move all terms containing w to the left and all other terms to the right.
+ 0.4w+1w-2w=0.2-2
We simplify left and right side of the equation.
-0.6w=-1.8
We divide both sides of the equation by -0.6 to get w.
w=3
