In 2017, solar and wind electricity generation totaled 218 thousand megawatt hours (mwh) wind generated 2 thousand mwh more than seven times that generated by solar energy. how much was generated by each sourc

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

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
