Answer:

Stock A daily average change in price for one share = -$2.16

Stock B daily average change in price for one share = -$1.45

Stock C daily average change in price for one share = -$1.43

Step-by-step explanation:

Since we desire to find the price of each stock per day or its daily average change in price for one share, we divide the price change of one share of stock by the total number of days it took to change.

So for stock A, daily average change = price change/number of days

price change = -$4.32, number of days = 2

daily average change  =  -$4.32/2 =  -$2.16

for stock B, daily average change = price change/number of days

price change = -$5.80, number of days = 4

daily average change  =  -$5.80/4 =  -$1.45

for stock C, daily average change = price change/number of days

price change = -$2.86, number of days = 2

daily average change  =  -$2.86/2 =  -$1.43

Score Frequency
RUDIKE [14]

Scores on an AP Exam at a local high school are recorded in the table. What was the average score?

Answer: D) 4.266 is correct

Explanation:

We are given the below frequency table:

Score Frequency

1         |         0

2        |         3

3        |         4

4        |        16

5        |       22

Let's denote the score by x and frequency by f.

The average formula is:

Average=\frac{\sum fx}{\sum f}

                    =\frac{(1\times0) + (2\times3)+(3\times4) +(4\times16) + (5\times22)}{0+3+4+16+22}

                    =\frac{0+6+12+64+110}{45}

                    =\frac{192}{45}=4.267

Therefore, the average score was 4.267

Hence the option D) 4.266
