2^4 - 3² + 7(0.5)

2 x 2 x 2 x 2 = 16

16 - 3² + 7(0.5)

3 x 3 = 9

16 - 9 + 7(0.5)

7 x 0.5 = 3.5

16 - 9 + 3.5

16 - 9 = 7

7+ 3.5 = 10.5

So your answer is C) 10.5.

Hope this Helps!!

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

A bag of apples weighs 7 7/8 pounds. By weight, 1/15 of the apples are rotten. What is the weight of the good apples?

siniylev [52]

The good apples are 14/15 of the total apples. So multiply the total apples by the weight of good ones to find the solution. $\frac{63}{8}*\frac{14}{15} = \frac{294}{40} = 7\frac{7}{20}lbs$
