Answer:

  76%

Step-by-step explanation:

Let f represent the score on the final. Then Inara wants the final grade to be ...

  0.25·74 +0.20·99 +0.55·x ≥ 80

  38.3 +0.55x ≥ 80

  0.55x ≥ 41.7

  x ≥ 41.7/0.55 ≈ 75.82

Inara needs a final exam grade of 76% or better to earn at least 80% in the course.

aleksley [76]
<h2>Answer:</h2>

The number of trees which are less than 20 meters are:

                                  9

<h2>Step-by-step explanation:</h2>

Based on the histogram we are asked to find the number of trees which are less than 20 meters in height.

  Class interval             Frequency

        4-8                             1

        8-12                            2

        12-16                           2

        16-20                          4

        20-24                          6

        24-28                          4

        28-32                          2

i.e. we are asked to find the  total number of tress that lie in the class interval 4-20.

i.e. we add the frequencies that lie in the interval 4-20

i.e. Number of trees= 1+2+2+4=9 trees.
