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>
Answer:
d). 14 and 240
Step-by-step explanation:
According to the Question,
- Given that, The regression model involving 14 independent variables and 255 observations
We need to find out the numerator and denominator freedom degrees
,
k = 14 regression variable
= n - k - 1
= 255 - 14 - 1
= 240 residuals
df=14,240
-
Now The degree of freedom for F-critical is
F_{k,n-k-1}=F_{14,240}
So, The df of the numerator is 14 and df of the denominator is 240
One way is to make into fracitons and simplify
A.5/7=25/35?
yes, true
B. 6/9=18/36?
no
C. 9/18=16/36?
no
D. 35/120=75/250?
no
another way is
if a/b=c/d, then (ad)/(bc)=1 or ad=bc
A is answer
You have to make proportions
65mi/1h=125mi/xhours
you end up with 65x=125
125/65=1.92hours--> round it to 2 hours
it takes 2 hours
