Patrick just completed the performance appraisals of three new statisticians. On the company’s 4-point grading scale, the averag
jeka94

Answer:

Option A is correct.

The new recruits' new hire performance was 14% below average.

Step-by-step explanation:

Breaking down the options one at a time.

New hire performance is a performance appraisal of new recruits of a firm by the HR. And from this question, the average performance score obtained (3.0) by the new hires is truly 14% lower than the 3.5 normal average score of statisticians already in that firm. This is evidently the answer to this question.

Cost per hire is the average amount spent per hire in a firm. It includes training costs, travel costs, administrative costs etc. This isn't evidently the answer to the question.

Time required to hire is the time taken to complete the hiring process of a new employee. This is obviously not also the answer to this question.

New hires turnover is the proportion of new hires that leave the firm within the first year of working with the firm. Also obviously distinct from what the question.is describing.

So, new hire performance is the most appropriate answer of all the answer choices.

Hope this Helps!!!

Kevin and Randy Muise have a jar containing 53 coins, all of which are either quarters or nickels. The total value of the coins
lilavasa [31]
So here is how you'll get the answer.
Let x be the number of quarters in the jar. 
Then 53-x is the number of nickels in the jar. 
<span>We also know .25x + 0.05 (53-x) = 10.25
</span>So next, we solve for x.
.25x + 2.65 - 0.05x = 10.25
0.2x +2.65 = 10.25
0.2x = 10.25 -2.65
0.2x = 7.40
x =37
Therefore, there are 37 quarters in the jar.
53-37 is 16. So there are 16 nickels in the jar.
Hope this answer helps.

What value of m will make this expression equal to 0?
Svetllana [295]

Answer:

-2.25

Step-by-step explanation:

The only way the expression can equal zero is if the numerator is zero.

The numerator is the product of 5 and the expression m + 2.25

A product is equal to zero if one of the factors equals zero.

5 is obviously not equal to zero, so the only way the product of 5 and m + 2.25 can equal zero is if the factor m + 2.25 equals zero.

We set m + 2.25 equal to zero and solve for m.

m + 2.25 = 0

Subtract 2.25 from both sides.

m = -2.25

If you add -2.25 to 2.25, you get zero. Zero times 5 equals zero. That meakes the expression equal to zero.

Answer: -2.25
