Answer:
2,157.89 KWH is the upper bound of the interval estimate for the population mean.
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= 2,000 KWH
Sample size, n = 33
Alpha, α = 0.01
Population standard deviation, σ = 106 KWH
99% Confidence interval:
Putting the values, we get,
2,157.89 KWH is the upper bound of the interval estimate for the population mean
Answer:
10.24 in²
Step-by-step explanation:
First we need to know how to find the area of a rectangle, which is base * height.
We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.
To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.
We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!
Answer:
y=0
Step-by-step explanation:
For the x axis, the value of y is zero
y=0
The new coordinates should be P= (-7, -8) O= (5, -7) and W= (-2,-4). Graph those points and you have your reflected triangle! I hope this helps!!
