Answer:
The maximal margin of error associated with a 99% confidence interval for the true population mean backpack weight is 4.81 ounces
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.
So
The maximal margin of error associated with a 99% confidence interval for the true population mean backpack weight is 4.81 ounces
Answer:
The value of x is 73.5.
Step-by-step explanation:
Given:
7/10=x/105.
Now, to find the value of 
So, to get the value of 
we use cross multiplication:
By cross multiplying we get:
By dividing both sides by 10 we get:
Therefore, the value of x is 73.5.
G(x) = -x^6 is a refrection of the graph of f(x) = x^6 across the y-axis.
my answer is in this picture.
