Answer: The confidence interval would be (120.6, 159.4).
Step-by-step explanation:
Since we have given that
n = 200
mean =
Standard deviation =
At 95% confidence interval, z = 1.96
So, 95% confidence interval would be
Hence, the confidence interval would be (120.6, 159.4).
The answer is 160 because you add the two together
Answer:
x = -9 + 11y
Step-by-step explanation:
Simplifying
2x + -22y = -18
Solving
2x + -22y = -18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '22y' to each side of the equation.
2x + -22y + 22y = -18 + 22y
Combine like terms: -22y + 22y = 0
2x + 0 = -18 + 22y
2x = -18 + 22y
Divide each side by '2'.
x = -9 + 11y
Simplifying
x = -9 + 11y
Hope this helps!!
