Answer:
-128
Step-by-step explanation:
(-2)^2 * (-2)^5 <---
First, add the exponents
(-2)^7<----
If you evaluate this you will get
-128
You just have to substitute the x for the given number and complete the equation. Leave the x-box and laziness and study
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: <u>218,000mwh = W + S </u>
RELATION BETWEEN W AND S: <u>W = 2,000mwh + 7S</u>
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
We know that out of the 1996 people, 294 had high blood pressure. We can use that to create a fraction.
294/1996 = 147/998 = 0.14729...
The probability of the next person having blood pressure is about 15%.
