Answer:
A. 
Step-by-step explanation:
We have been given an equation of a line in point-slope form. We are asked to write our given equation in standard form.

Since we know that standard form of equation is:
, where, a, b and c are constants.
Let us multiply both sides of our given equation by 2.


Let us add 6 to both sides of our equation.


Let us subtract x from both sides of our equation.


Multiply both sides of our equation by -1.

Rearranging our equation we will get,

Therefore, the standard form of our given equation is
and option A is the correct choice.
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
where
k is the constant of variation
in this problem we have
the point 
so

substitute


therefore
<u>the answer is</u>

Answer:

Step-by-step explanation:
Z-score:
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:

You listen to the radio station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 17 minutes. Calculate the z-score for this amount of advertising time.
We have to find Z when X = 17. So
