Answer:
The probability that x is less than 9.7 is 0.0069 = 0.69%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
The probability that x is less than 9.7 is _____.
This is the pvalue of Z when X = 9.7. So
has a pvalue of 0.0069
The probability that x is less than 9.7 is 0.0069 = 0.69%
Answer:
Step-by-step explanation:
The reference angle is an acute angle that angle in standard position makes with the positive x-axis.
The given angle in radians is
This angle is already acute and hence it is itself a reference angle.
The reference angle of any angle in the first quadrant is the same angle.
