To have all positive terms I think
Answer:
30
Step-by-step explanation:
We know that population mean μ is 30 and population standard deviation σ is 5.
Further average or mean is computed for all sample means. So, the mean of sampling distribution of mean μxbar is calculated.
The property of sampling distribution is that mean of all possible sample means or mean of of sampling distribution of mean μxbar is equal to the population mean μ.
μxbar=μ=30
μxbar=30.
Thus, the obtained value will be 30.
Answer:
Reflects it about x-axis and down 3 units
Step-by-step explanation:
y = f(x) + C C < 0 moves it down
This is moved down 3 units
y = −f(x) Reflects it about x-axis
Simplifying
6y = 8 + -9 + 6y
Combine like terms: 8 + -9 = -1
6y = -1 + 6y
Add '-6y' to each side of the equation.
6y + -6y = -1 + 6y + -6y
Combine like terms: 6y + -6y = 0
0 = -1 + 6y + -6y
Combine like terms: 6y + -6y = 0
0 = -1 + 0
0 = -1
Solving
0 = -1
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
The correct answer is 99.
