Question

Yeooo so I need help I’m confused

Answer 1

Answer:et's see, we want the average increase of % in female students

First of things first, we need to know how much it increased year by year

So

1980 it was 6,7% and 1990 it was 10,2%

10,2% - 6,7% = 3,5%

The % increased in 3,5% from 1980 to 1990

Applying it to the others we have:

1980 to 1990 = 3,5%

1990 to 2000 = 3,1%

2000 to 2012 = 8,2%

So we have 3 percentages and we want the average, so lets sum them and divide by 3

(3,5 + 3,1 + 8,2)/3 = 14,8/3 = 4,933333...%

Rouding 4,93333...% we have 4,9%

Answer 2

angles 1 and 2 are not congruent (A)

Explanation:

They are supplementary angles. The only way for supplementary angles to be congruent is that they both are equal to 90 degrees. We can see in this figure that they are not right angles. Therefore, we can conclude they are not congruent. HTH :)
