We have been given an expression . We are asked to find the value of A when rewrite our given expression as .
To solve our given problem, we will use exponent properties.
Using exponent property , we can rewrite our given expression as:
Now, we will compare our expression with .
Upon comparing with , we can see that .
Therefore, the value of A is .
We can further simplify as:
Find the greates number we can divide them evenly by
that is also called the greatest common factor
so
factor each
20=2*2*5
100=2*2*5*5
common gropu is 2*2*5=20
20 groups can be made
each group can have 5 cookies and 1 brownie
Answer:
And we are confident that the true mean for this case is given by
Step-by-step explanation:
Data given
represent the sample mean for the WBC
population mean
s=3.9265 represent the sample standard deviation
n=187 represent the sample size
Confidence interval
The confidence interval for the true mean is given by:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The degrees of freedom, are given by:
The Confidence level is 0.90 or 90%, the significance is and , the critical value for this case would be
Replacng into the formula we got:
And we are confident that the true mean for this case is given by
