Answer:

Exam score

Step-by-step explanation:

The response variable also known as the d pendent variable, is simply the variable we intend to measure based in a set of variables (independent variables or explanatory variables) which might cause it to change. For instance, the scenario above aims to look into how a certain relaxation method will affect the exam score, here, the variable we intend to measure is the response variable which is exam score. The exam score is affected by the impact the relaxation method has on the student, hence, the relaxation method is the independent or explanatory variable.

What is the argument of -5\sqrt{3}+ 5i?

Shtirlitz [24]

Answer:

150 degrees

Step-by-step explanation:

Graphing the complex number we see the angle terminates in the second quadrant. This means the argument, the angle, will be between 90 degrees and 180 degrees.

So if we create a right triangle with that point after graphing it. We see the height of that triangle is 5 because that is the imaginary part. The base of that triangle has length $5\sqrt{3}$ . The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.

Let's find the complementary angle.

So the opposite side of the complementary angle is 5.

The adjacent side of the complementary angle is $5\sqrt{3}$ .

$\tan(\theta)=\frac{5}{5\sqrt{3}}$

$\tan(\theta)=\frac{1}{\sqrt{3}}$

$\theta=\tan^{-1}(\frac{1}{\sqrt{3}})$

$\theta=30$

So 90-30=60.

The answer therefore 60+90=150.

Solve:

riadik2000 [5.3K]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Let's solve ~

$\qquad \sf \dashrightarrow \: \dfrac{2x - 1}{5} = \dfrac{x - 2}{2}$

$\qquad \sf \dashrightarrow \: 2(2x - 1) = 5(x - 2)$

$\qquad \sf \dashrightarrow \: 4x - 2 = 5x - 10$

$\qquad \sf \dashrightarrow \: 5x - 4x = -2 + 10$

$\qquad \sf \dashrightarrow \: x = 8$

Value of x is 8

The residual plot for a data set is shown.

BaLLatris [955]

The correct answer is: D. The regression line is not a good model because the points in the residual plot form a curve. (i know this because i just passed the test ;) )

the gross earnings • group health insurance (assuming 15% of gross earnings) pension deduction (assuming 6.5% of gross earnings)

sveta [45]

Step-by-step explanation:

Calculate the gross earnings:

40*7.75 = 310.00

Health insurance deduction:

310.00*15/100 = 46.50

Pension deduction:

310.00*6.5/100 = 20.15

Total deductions:

55.00 + 15.50 + 21.25 + 46.50 + 20.15 = 158.40

Net pay:

310.00 - 158.40 = 151.60

Wesley and Lincoln went fishing. Wesley caught a fish 15 3/16 inches long and Lincoln caught a fish 12 3/4 inches long. How many

Arlecino [84]

Answer:

2 7/16 inches longer

Step-by-step explanation:

15 3/16 - 12 3/4= 243/16 - 51/4 = 243/16 - 204/16= 39/16 inches longer

39/16=2 7/16 inches longer
