Answer:
V≈58.11ft³
Step-by-step explanation:
that is the answer because you are trying to find the volume.
We are going to want to change any mixed number into an improper fraction. 2 3/4 is 11/4 and 1 2/5 is 7/5.
We are going to set up a proportion where the lbs are on the top and the money is on the bottom. x is going to be how much it costs for 2 3/4 lbs of lunch meat.
(7/5)/3.36 = (11/4)/x
Cross multiplication \/
7/5x = 9.24
x = 6.60
As a final answer, the 2 3/4 lbs of lunch meat cost $6.60
Answer:
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
Find the margin of error for the confidence interval for the population mean with a 98% confidence level.
The margin of error for the confidence interval for the population mean with a 98% confidence level is 2.88 miles per hour.
Answer:
a³ - a² - 3a+ 6
Step-by-step explanation:
we are asked by how much does (a³-2a) exceed (a²+a-6)
in other words, we are being asked to find the difference between the 2 terms above.
Mathematically we are asked to find:
(a³-2a) - (a²+a-6) (expand parentheses by distribution property)
=(a³-2a - a²- a + 6)
= a³ - a² - 3a+ 6 (answer)
