Answer:
W=191,000MWH S=27,000MWH
Step-by-step explanation:
OK, let's W be wind electricity generated and S, solar electricity generate.
TOTAL GENERATED: 218,000mwh = W + S
RELATION BETWEEN W AND S: W = 2,000mwh + 7S
We have now two equations:
218,000 = W + S
W = 2,000 + 7S
Put th value of W into the 1st equation in order to find S:
218,000 = 2,000 + 7S + S
218,000 = 2,000 + 8S
218,000 - 2,000 = 8S
216,000 = 8S
S = 216,000/8
S = 27,000mwh
Now, we find W.
W = 2,000 + 7*27,000mwh
W = 2,000 + 189,000mwh
W = 191,000mwh
I'm only in 8th grade and i didnt learn this yet buuut i think it 2 with a remainder because 9+10 would be 19 and then that divided by 7 would be 2.714285 repeated... but then if you round it would be 2.7 0-0

Step-by-step explanation:
Answer:
The length for the 97th percentile for a man's arm span is 74.96 inches.
Step-by-step explanation:
We have a normal distribution for men's arm span, with mean of 68 inches and standard deviation of 3.7 inches.
The 97th percentil represents the value for which 97% of the observations are below.
We can search for the 97th percentile for the standard normal distribution. This will give a value z=1.88.
Then, we can convert this z-score to our distribution:
![X=\mu+z\cdot\sigma=68+1.88\cdot 3.7=68+6.96=74.96](https://tex.z-dn.net/?f=X%3D%5Cmu%2Bz%5Ccdot%5Csigma%3D68%2B1.88%5Ccdot%203.7%3D68%2B6.96%3D74.96)
