Answer: 7/3

Step-by-step explanation:

To divide fractions, you can use the "keep, change, flip" method.

1. Keep the first fraction (7/9) as is.

2. Change the division sign to a multiplication sign.

3. Flip the second fraction (i.e. find the reciprocal). This means 1/3 changes to 3/1.

Rewrite the equation:

7/9 x 3/1

Multiply the numerators and the denominators together, respectively.

21/9

Simplify:

7/3

When estimating a job to bid, a contractor’s estimator first determines the actual cost of labor using the function L(h) = 28.75

dybincka [34]

Answer:

M(h) = 73.18025h

Step-by-step explanation:

The composite function is ...

M(B(L(h))) = M(B(28.75h)) = M(1.78(28.75h)) = M(51.175h)

= 1.43(51.175h) = 73.18025h

The composite function is ...

M(h) = M(B(L(h))) = 73.18025h

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
