The percentage of the golf clubs original price to its new inflated price is: %1.15 more expensive. To find out the percentage, we just need to divide 552 by 480: 552/480 is 1.15. That is our percentage.
Answer:
0.3 or 30%
Step-by-step explanation:
The professors will only seek a smaller publisher if they cannot place the statistics book with a major publisher. If the probability of getting a major publisher is 40% and the probability of getting a smaller publisher is 50%, then the probability that the statistics book would wind up being placed with a smaller publisher is given by:
The probability is 0.3 or 30%.
Answer: 89.7
Step-by-step explanation:
The mean of a data set is the average of all the information given. Therefore, the total combined score is the number of students multiplied by the mean
The total score of the first 44 students: 96.6*44 = <em>4250.4</em>
The total score of the later 13 students: 66.3*13 = <em>861.9</em>
(4250.4 + 861.9)/(44 + 13) = 89.7

To get the probability that randomly selected airfare between Boston and San Francisco will be more than $450, we proceed as follows:
the z-score is given by:
z=(x-μ)/σ
thus the z-score for our information will be:
z=(450-387.20)/68.50
z=0.9168
hence our probability will be:
P(X>x)=1-P(z)
P(z)=0.8212
thus
P(X>x)=1-0.8212=0.1788~17.88%
