Hello!

As we can see, our a value, which would be the coefficient of $x$ , which determines our slope, is negative, meaning that this whole line is negative.

Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.

If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.

Gavin was thinking of a number. Gavin halves the number and gets an answer of 34.3. Form an equation with x as information.

Lostsunrise [7]

Gavin's number is 68.6

Equation: 1/2(x) = 34.3

Use inverse operations on both sides.

1/2(x) = 1x or x = 34.3(2)

34.3(2) = 68.6

Thus, x equals 68.6

The angle 01 is located in Quadrant IV, and sin(01) = -24/ 25<br><br> What is the value of cos(01)?

pav-90 [236]

Answer:

$\frac{7}{25}$

Step-by-step explanation:

We can solve that using this identity,

$\sin {}^{2} (x) + \cos {}^{2} (x) = 1$

plug in -24/25 from x in sin

$\sin {}^{2} ( \frac{ - 24}{25} ) + \cos {}^{2} (x) = 1$

$\sin( \frac{576}{625} ) + \cos {}^{2} (x) = 1$

$\cos {}^{2} (x) = 1 - \frac{576}{625}$

$\cos {}^{2} (x) = \frac{49}{625}$

$\cos(x) = \frac{7}{25}$

Since cos is positve in quadrant 4, the answer is 7/25.

The results of a study exhibit response bias. Select the statement that best describes the bias in the study.

dmitriy555 [2]

Answer:

"The interviewer for the study did not record the responses of the subjects accurately." I believe this is most pertinent. B, or the boss of the subjects, could have been an answer, but if all members associated in the study exhibit the similar level of response bias based upon superior employers, then the study remains somewhat accurate, but C, or inaccurate record of responses, would remain biased entirely.
