An avid golf fan recorded the scores of 75 golfers on the ninth hole of the Cottonwood Golf Course as follows :
Vadim26 [7]

Answer:

<u>The correct answer is 3.77 strokes as the average score for the ninth hole of the Cottonwood Golf Course.</u>

Step-by-step explanation:

1. To find the average score, we need to know how many strokes the 75 golfers needed to play this ninth hole. For doing that, we will do the following addition, using the frequency data given:

1 x 1 = 1

1 x 2 = 2

32 x 3 = 96

27 x 4 = 108

8 x 5 = 40

6 x 6 = 36

1 + 2 + 96 + 108 + 40 + 36

<u>283</u>

<u>This means that all the 75 golfers scored 283 strokes for playing the ninth hole</u>

2. Now that we know that the total number of strokes was 283, we will do a division for find the average score, using also the number of golfers. For doing it, we will do the following division:

Total number of strokes/ total number of players

<u>283/75 = 3.77</u>

<u>The average score is 3.77. It means that the 75 golfers in average hit 3.77 strokes to play the ninth hole.</u>

Brennan has already run 16 miles on his own, and he expects to run 3 miles during each track practice. How many track practices
pentagon [3]

Answer:

It would take Brennan 4 track practice runs.

Step-by-step explanation:

He has already run 16 miles and needs to run 28 in total. If we are counting the 16 in the 28 miles, he would need to run only 12 more to reach his goal. And if he runs 3 miles a run, it would take him about 4 runs to finish his 28-mile goal.

(28-16=12 and 12/3=4)
