Answer:
<h2><u><em>
m = 1/5</em></u></h2>
Step-by-step explanation:
4m = 6m - 2/5
-2m + 2/5 = 0
m = (-2/5)/-2
m = 1/5
---------------
check
4 * 1/5 = 6 * 1/5 - 2/5
4/5 = 6/5 - 2/5
<em>4/5 = 4/5</em>
<u>the answer is good</u>
Answer: 9+ -10k
Step-by-step explanation: You need to simplify and you multiply the -3 to everything in the parentheses. Then you have your answer
36 divide 4 equals 9 i know because 9 times 4 equals 36
9 + 9 + 9 + 9 = 36
Answer:
We can say at 99% confidence that the true mean is between (91.674;98.326)
Step-by-step explanation:
Data given
represent the sample mean
population mean (variable of interest)
s=6.6 represent the sample standard deviation
n=30 represent the sample size
The confidence interval for the mean is given by the following formula:
(1)
We need to find the critical value and we need to find first the degrees of freedom, given by:
Since the Confidence is 0.99 or 99%, the value of and , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.005,29)".And we see that
And replacing we got:
We can say at 99% confidence that the true mean is between (91.674;98.326)
