Step-by-step explanation:
Answer:
5 cans
Step-by-step explanation:
First multiply 15 by 3 to see how many ounces are needed in total: 15x3=45
Then divide 45 by 9 to see the amount of cans: 45/9=5
Answer:
is it 82 degrees?
Step-by-step explanation:
Answer:
The 90% confidence interval for population mean is 
Step-by-step explanation:
From the question we are told that
The sample mean is 
The confidence level is 
The sample size is 
The standard deviation
Now given that the confidence level is 0.90 the level of significance is mathematically evaluated as


Next we obtain the critical value of
from the standardized normal distribution table. The values is 
The reason we are obtaining critical values for
instead of that of
is because
represents the area under the normal curve where the confidence level 1 -
(90%) did not cover which include both the left and right tail while
is just considering the area of one tail which is what we required calculate the margin of error
Generally the margin of error is mathematically evaluated as

substituting values


The 90% confidence level interval is mathematically represented as

substituting values



It is in simple form. There is absolutely nothing more that can be done, unless it is a joke. And math jokes are very hard to come by.
I don't think that y(y - 1)/(a + 2b) is any simpler.
Come to think of it, is that x^2 or y^2 on the top left.
I think my first answer is the best one. Nothing can be done.
