Answer:

x ≈ 16.52

Step-by-step explanation:

Use the tangent ratio in the right triangle to find x

tan36° = \frac{opposite}{adjacent} = \frac{12}{x}

Multiply both sides by x

x × tan36° = 12 ( divide both sides by tan36° )

x = 12 / tan36° ≈ 16.52 ( to 2 dec. places )

What is the solution of the linear system?
lozanna [386]

Answer:

(3,-4)

Step-by-step explanation:

Given

-7x - 2y = -13

x = 2y + 11

Required

Find the solution

Substitute 2y + 11 for x in the first equation

-7(2y + 11) - 2y = -13

Open bracket

-14y -77 - 2y = -13

Collect Like Terms

-14y - 2y = -13+77

-16y = 64

Solve for y

y = \frac{64}{-16}

y = -4

Substitute -4 for y in x = 2y + 11

x = 2(-4) + 11

x = -8 +11

x = 3

Hence, the solution is (3,-4)

A social psychologist predicted that ratings of an individual’s social desirability would be influenced by their physical attrac
marshall27 [118]

Answer:

It is stated in the query that the more attractive the individual, the higher their rank of desirability.

Step-by-step explanation:

This means that we should conclude that the alternative explanation of "higher degree of desire contributes to higher levels of social attractiveness"

In the event of a null hypothesis, we will believe that the degree of attractiveness has no impact on the score of cultural desirability.

(1) Null hypothesis:- The level of attraction does not have an impact on the rating of social desirability.

(2) Alternate hypothesis:- The level of attraction has a positive effect on the ranking of social desirability.

(3) The error of Type I is characterized as the rejection of the true null hypothesis. Therefore, in this case, the type I mistake would be that "the level of attraction has a positive effect on the rating of social desirability while the level of attraction does not have an impact on the rating of social desirability."

(4) The error of type II is characterized as the failure to reject the false null hypothesis. Thus, in this situation, the Type II error would be that "the level of attraction has no impact on the rating of social desirability while the real level of attraction has a positive effect on the rating of social desirability."

(5) We know that the likelihood of having a Form I error is equal to the degree of significance (in percent terms). The significance level, in this case, is 0.05, so the likelihood of making a form I error is 0.05 * 100=5 percent.

Therefore, there is a 5 percent risk of making a Type I mistake.
