Cindy is a first-year math teacher who has just collected a chapter test from her 4th period students. As Cindy reviews the test

scores, she notices that while she has several students who have earned an A, most of the test scores are in the C to B range. She also notices that two of the scores are much lower than the rest, each earning an F. This makes sense to her, as those two students were absent for much of the chapter. However, she must now report to her principal on the performance of her class on this test. Which measure of central tendency should Cindy use in her report to the principal, if she wants to portray her students in the most favorable manner?
A.
Cindy should use the mean of the test scores to produce the most positive report.
B.
Cindy should use the median of the test scores to produce the most positive report.
C.
Cindy should use the mode of the test scores to produce the most positive report.
D.
Cindy should use either the mean or the median, as these will produce the same value.

An investor has an account with stock from two different companies. Last year, his
Lesechka [4]
22.7%

Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%

Can I get help with this
Marta_Voda [28]

Answer:

X = 60

Y = 50

Step-by-step explanation:

The total degrees of a triangle is 180 degrees. For the middle triangle, 50+70=120 so 180-120=60.

On the far right, Y=50 because you take 50 degrees from the middle triangle, and insert it there.

Identifiy the initial amount a and the decay factor b in the exponential function y=5×0.5^×
xenn [34]

Answer:

a=5\\ \\b=0.5

Step-by-step explanation:

Given the exponential decay function y=5\cdot (0.5)^x

When x=0, then

y=5\cdot (0.5)^0=5\cdot 1=5,

so the initial amount is a=5

The exponential decay function y=a\cdot b^x has the decay factor b.

In your case, the eexponential decay factor is b=0.5
