Answer:
The probability that the average score of the 49 golfers exceeded 76 is 0.0228
Step-by-step explanation:
To find the probability that the average score of the 49 golfers exceeded 76, we need to calculate z-score of the score 76.
Z-score can be calculated as follows:
z= where
- X=76
- M is the mean score of all golfers (75)
- s is the standard deviation of the scores (3.5)
- N is the sample size (49)
then z(76)= = 2
By looking at the z-table we find that the probability of z-values of scores smaller or equal to 2 is Pr(Z<2)=0.9772. Therefore
The probability that the average score of the 49 golfers exceeded 76 is 1-0.9772=0.0228
Answer:
c
Step-by-step explanation:
75 is supplementary to angle b. then angle a = 180-75=105
Number one and three is the answer
Answer:
The answer would be correctly written as $10.10, and the work would be shown.
Step-by-step explanation:
We know the sale amount is ...
extended price = (quantity)·(price each)
When the price is reduced 8¢, the total amount of the sale is ...
extended price = 2·($5.13 -0.08) = 2·$5.05 = $10.10
