torisob [31]
It would be neither... you would have to draw it out. East to West would be a horizontal line, and North to South would be a vertical one. If it keeps going forever such as a line or a ray, then it would end up intersecting. Meaning it would become perpendicular. Hope this 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.

Find the distance between 4 2/3 and −5 1/3
svetoff [14.1K]

Answer:

The distance between these two is 10.

Step-by-step explanation:

In order to find this, we simply need to subtract the values from one another. If the value is then negative, we take the absolute value to find the distance.

4 2/3 - -5 1/3

4 2/3 + 5 1/3

vova2212 [387]

Answer:

B. 6

Step-by-step explanation:

The picture of the question in the attached figure

we know that

A translation and a reflection are rigid transformations, that produce congruent figures'

Remember that

Two figures are congruent if their corresponding sides and their corresponding angles are congruent

In this problem

Triangle JKL and Triangle J'K'L' are congruent

so

JL=J'L'

substitute the given values

8=2x-4

solve for x

2x=8+4\\2x=12\\x=6
