Answer:
x= 12
Step-by-step explanation:
Here we have vertical angles, this means that they are angles that are across from each other on vertical lines. So, they equal each other.
The equation would be: 60= 5x
The only step is to divide 5 to both sides of the equation.
<u>60</u>= <u>5x</u>
5 5
x= 12
Answer:
The lower limit of 95% confidence interval is 99002.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $100,000
Sample mean,
= $111,000
Sample size, n = 36
Alpha, α = 0.05
Population standard deviation, σ = $36,730
First, we design the null and the alternate hypothesis

We have to find the lower limit of the 95% confidence interval.
95% Confidence interval:

Putting the values, we get,


The lower limit of 95% confidence interval is 99002.
B: 60. You solve it by dividing 39 by 0.65
