Answer:
We are 99% confident that the true mean of electricity comsumption is between (15.6 and 15.8) kWh
Step-by-step explanation:
Information provided
represent the sample mean for the usage of electricity
population mean (variable of interest)
represent the population standard deviation
n=1731 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula if we know the population deviation:
(1)
The Confidence level provided is 0.99 or 95%, the value of significance is 
and 
, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.005,0,1)".And we see that 
And replacing we got:
We are 99% confident that the true mean of electricity comsumption is between (15.6 and 15.8) kWh
3/4 x 90 degree = 67.5 degree
Answer:
So -8*<4 Is not a complete Problem... If your saying -8<4 then the anwser is 1. But im guessing your saying -8X<4 which is negative eight ex (x) less than four. so heres that:
Step-by-step explanation:
Let's solve your inequality step-by-step.
−8x<4
Step 1: Divide both sides by -8.
−8x/−8<4/−8
=x>−1/2
Answer:
12°
55°
Step-by-step explanation:
∠WXY=90°
∠ZXY=∠WXY- ∠WXZ= 90° - 35°= 55°
- 4x+7°= 55°
- 4x= 48°
- x= 48°/4
- x= 12°
