Answer:

2. 3/4, 50%, 1/4, 12.5%

Step-by-step explanation:

Work completed at the 4 sites = 1/4, 50%, 12.5%, 3/4

1/4 = 0.25

50%

= 50/100

= 0.5

12.5%

= 12.5/100

= 0.125

3/4

= 0.75

in order from greatest to least?

3/4, 50%, 1/4, 12.5%

1. 12.5%, 1/4, 50%, 3/4

2. 3/4, 50%, 1/4, 12.5%

3. 3/4, 12.5%, 1/4, 50%

Jeanette obtained 32% for her statistics test, which was out of a total of 300 marks. How much should she score in the computer

Andre45 [30]

Using weighted average, it is found that she should score 67% on the computer science test.

The weighted average is given by each proportion multiplied by it's score.

In this problem, the proportions and scores are given by:

Proportion of 32% = 0.32 for a score of 300.
Proportion of x for a score of 200.
Proportion of 46% = 0.46 for a score of 300 + 200 = 500.

Then

$0.32(300) + 200x = 0.46(500)$

$200x = 0.46(500) - 0.32(300)$

$200x = 134$

$x = \frac{134}{200}$

$x = 0.67$

She should score 67% on the computer science test.
