Answer:
See below.
Step-by-step explanation:
The volume of the storage in the truck is 8.0 * 15.0 * 8
= 960 ft^3.
Now we would divide this by the volume of one box. This will give us the required number of boxes.
Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You need to apply the Distributive property on the left member of the equation:
2. Now, you must solve for , as following:
For this case we have the following equation:
p (x) = 8 + 6x-4x2
We must derive the equation to find the maximum of the function.
We have then:
p '(x) = 6-8x
We match zero:
6-8x = 0
We clear x:
8x = 6
x = 6/8
x = 3/4
x = 0.75 speakers
Answer:
should be sold 0.75 thousand boombotix speakers to maximize profit
Answer:
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
The lower bound of the interval is:
The upper bound of the interval is:
In this problem, we have that:
So
The confidence interval for the unemployment rate is (0.056, 0.06) = (5.6%, 6%).
