The answer would be B, there are no real solutions to the secretion because the Square root of a negative number is not a real number.
Answer: 34
Step-by-step explanation:
Absolute value is how many numbers is that number away from zero. -34 is 34 places away from zero.
~A
Z(x)=(x- mean) / standard deviation
Z(18)=(18-26)/4=-2
Answer:
The smallest sample size required to obtain the desired margin of error is 44.
Step-by-step explanation:
I think there was a small typing error, we have that
is the standard deviation of these weighs.
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

Which of these is the smallest approximate sample size required to obtain the desired margin of error?
This sample size is n.
n is found when 
So



Simplifying by 15



Rounding up
The smallest sample size required to obtain the desired margin of error is 44.
The average amount of corn produced per acre represented in scientific notation can be found using the below formula:

We are given:

Substituting the above information in the formula, we get...

Conclusion:

The average amount of corn produced per acre represented in scientific notation is option B)
bushels per acre
