Answer:
c) -1.75°
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 0, standard deviation of 1:
This means that
Find the reading that separates the bottom 4% from the others.
This is the 4th percentile, which is X when Z has a p-value of 0.04, so X when Z = -1.75.
The correct answer is given by option c.
The final answer should be x = 5 and y = 9 for part 1
Explanation:
1500 - 50(6) = 1200
1200/150 = 8
But since you need it to be greater than 1,500 it would be 9-weekday
shows instead
the solution x > 12 means the number of weekend shows is greater than 12 i believe
Y= +9
0+9=9
2+9=11
4+9=13
6+9=15
Answer:138
Step-by-step explanation:
Cost of a canoe is $12 and call number of days rented two mountain bikes are $18 and call number of days rented. That sum has to be < $138 (it should be less than or equal to $138, but that isn't a choice).12c+18m<$138C.
