Answer:
A. 2.5 standard deviations below the average salary.
Step-by-step explanation:
In a normally distributed sample, the z-score measure how many standard deviations a measure is above or below the mean.
If the zscore is positive, the measure is above the mean.
If it is negative, the measure is below the mean.
A quality control specialist calculated thez-score associated with his own salary and found it was minus2.50. What is his salary?
This means that his salary is 2.5 standard deviations below the mean, that is the average salary.
The correct answer is A.
Angles three and four are a linear pair, meaning that they they form a line. When two angles make a line, the measures add up to 180°. Adding the two values together, we see that 3x+27x=180. Simplifying and solving for x, we get 30x=180 ⇒ x=6.
The question, however, is asking for the measure of angle 4. Thus, we plug x=6 into 7x to get 6(7)=42.
