Answer:
q-(-5)=x
X=q+5
Step-by-step explanation:
we can divide this shape into two parts
(1) Hemisphere:
we can see that
radius is 8
now, we can use formula for volume
(2) Cylinder:
radius is 8
height is 7
we can use formula
now, we can add them to find total volume
..............Answer
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.
Answer:
y= 
Step-by-step explanation:
To find inverse of something, just switch the variables
x=y^2
now try to solve back in terms of y
y=
