Enter the values for the highlighted variables to complete the steps to find the sum:

umka21 [38]

Answer:

a = -1
b = -9
c = 9
d = 3
e = 3
f = 2
g = 3/2 = 1.5

Step-by-step explanation:

For "a", we recognize that 6-2x is the opposite of 2x-6, so multiplying the latter by -1 will give the former. a = -1

For "b", we notice the denominator no longer has -1 as a factor. Rather, that has be applied to the numerator, which is now -9. b = -9

For "c" we have combined the two numerators over the common denominator. Note that the sign is already provided. 3x +(-9) = 3x -9. c = 9

For "d" and "e", we recognize that 3 is a factor of both terms of the numerator of the previous expression. Here, we factor that out. d = 3, e = 3

The common factor of the terms in the denominator is factored out to find "f". That value is 2. f = 2

The numerator and denominator factors of (x -3) have been cancelled in the last step, leaving the result d/f = 3/2. This is the value of the simplified expression, hence the value of g. g = 3/2 = 1.5

<em>Comment on g</em>

We don't know if your answer checker is able to accept fractions as input, so we have expressed g both as a fraction and as a decimal number.

Describe the slope of the line. Then find the slope. What’s the slope?

guajiro [1.7K]

Hello there!

We are given two points.

We use the following formula:

$\frac{y2-y1}{x2-x1}$

$\frac{4-7}{0-(-1)}$

$\frac{4-7}{0+1} \\\frac{-3}{1} \\-3$

So the slope is -3. Hope it helps!

After running the t-test provided in the directions, for each of the test variables (AGE, PAEDUC, and EDUC) please provide the M

marishachu [46]

Answer:

11. This is totally correct (See attached image)

12. Consider Age.

Suppose, we want to test H0: mean age(White)=mean age(Black) against H1: mean age(White)>mean age(Black) and we find the one sided p value (which is just half of the 2 tailed p value) less than 5% and hence the difference is significant

Consider Father education.

Suppose, we want to test H0: mean years of father's education(White)=mean years of father's education(Black) against H1: mean years of father's education(White)>mean years of father's education(Black) and we find the one sided p value (which is just half of the 2 tailed p value) less than 5% and hence the difference is significant

Consider Highest year of school completed.

Suppose, we want to test H0: mean completion(White)=mean completion(Black) against H1: mean completion(White)>mean completion(Black) and we find the one sided p value (which is just half of the 2 tailed p value) less than 5% and hence the difference is significant

Thus, we find significant difference with respect to education and life expectancy. However, it is difficult to comment on racial inequality, it requires further information on whether equal opportunity was available for both and some related administrative information.

Step-by-step explanation:

250,000 x 0.05 = 12,500

12,500 a year

12,500 / 12 = 1041.66

1041.66 a month
