Answer:

a) AB = 17 m

b) AC = 20.8 m

Step-by-step explanation:

Pythagorean theorem

a^2 + b^2 = c^2

AB^2 = (26-11)^2 + 8^2

AB^2 = 15^2 + 8^2

AB^2 = 225 + 64

AB^2 = 289

AB = 17 m

AC^2 = AB^2 + BC^2

AC^2 = 17^2 + 12^2

AC^2 =289 + 144

AC^2 = 433

AC = 20.8 m

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
