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
The circumference of a circle of given diameter d is pi*d.
Thus, if the diameter is d = 6 cm, the circumference of the circle is (6 cm)*pi.
Answer:
the answer for this question is 1000times.
Step-by-step explanation:
the value for 9 in 157,900 is nine hundred(900).and the value of 9 in 901,532 is nine hundred thousand(900000).
900×1000= 900,000.
