Answer:
Step-by-step explanation:
The confidence interval gives a range of values that could contain the population mean.
Confidence interval is written as
Sample mean ± margin of error
Confidence interval does not express probability.
Given that the sample mean home price for city A is $189500 and the sample mean home price for city B is $185000, the difference in the sample mean home prices for both cities is
189500 - 185000 = $4500
Since the margin of error for 95% confidence interval for the difference in average home price between the two cities (A-B) to be $3400, then
The upper limit of the confidence interval is
4500 + 3400 = $7900
The lower limit of the confidence interval is
4500 - 3400 = $1100
Therefore, the correct conclusion is
Beatrice can be 95% confident that the average home price is between $1100 and $7900 more in city A than in city B.
These are vertical angles so the opposite angle would equal each other.
Let’s start by solving for x:
52=x-15
Add 15 to both sides:
x=67 degrees
Now let’s solve for y:
4y=128
Divide 4 to both sides:
y=32 degrees

9 27
cross multiply (7*27=189) and divide (189/9=21)
M = 21
