Answer:

Below.

Step-by-step explanation:

(sine) sin=30=1/2

=cos [90-30]

Which means cos=60

Same as:

(cosine) cos=60=1/2 or Sin30=Cos 60=1/2

Hence, the answer is...

cos 60° = ½....

Step-by-step explanation:

The sine of an angle is the same as the cosine of its complement.

If sin 30° = ½, then cos 60° = ½.

Angelina_Jolie [31]
Add (-2X) to both sides:
2X + B + (-2X) = C + (-2X)
If we (rearrange) it into B + 2X + (-2X) = C + (-2X)
B + 2X - 2X = C + (-2X)
Since +2X - 2X = 0
B + 0 = C + (-2X)
B = C + (-2X)
B = C - 2X

A scientist is investigating whether percent concentration can be used to predict density in apple juice. A scientist selected a
USPshnik [31]

Answer:

The most appropriate inference procedure for the investigation is;

a. A linear regression t-interval for the slope

Step-by-step explanation:

Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'

The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant

Therefore, a linear regression t-interval for the slope is most appropriate.
