Which teacher exhibited the most variable year to year performance over this 5 year span?

1 answer:

3 0

I do not have the graph that you are referencing from this question to, but I can help you get led to the right answer. If the teacher exhibits the most variable year to year performance over a 5 year span, then the graph must show unstable fluctuating of figures. Those who are least variable would have a steady line going up or down or maybe even just straight.

Answer:

$B2 = 0.465$ --- Population standard deviation

$C2 = 0.216$ --- Population Variance

Step-by-step explanation:

Given: Wake-up time data

Required: Determine the population standard deviation and the population variance using Excel

First, enter the given data in Excel

For this question, I entered the data in cell A2 through cell A21

Cell B2 and Cell C2 were used to hold the results of the population standard deviation and the population variance, respectively.

In cell B2, the formula to use is:

=ROUNDUP(STDEV.P(A2:A21),3)

The round function rounds the result to 3 decimal places while STDEV.P calculates the population standard deviation.

So, the result is:

$B2 = 0.465$

In cell C2, the formula to use is:

=ROUND(VAR.P(A2:A21),3)

The round function rounds the result to 3 decimal places while VAR.P calculates the population variance.

So, the result is:

$C2 = 0.216$

The equation for simple interest is

Simple Interest=P×r×n

where:

P=Principal amount

r=Annual interest rate

n=Term of loan, in years

Monisha and Dave each sold magazine subscriptions as part of a fundraiser. Monisha raised 1/2 as much money as Dave raised. Toge

1) Change the word problem into an equation:
.5x+x=213.75 where x equal the amount of money Dave earns.
2) Combine the like terms: .5x+x=1.5x
3) Now solve: 1.5x=213.75 and use multiplicative inverse to get your answer of 142.5
4) Now wait, this is the amount Dave earns not the amount Monsiha earns, however we know that Monsiha earns half that, therefore:
142.5÷2=75.25

The answer would be 'Monsiha raised $75.25 in total'.
