Answer:
P(57 < X < 69) = 0.1513
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:
Find P(57 < X < 69):
This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So
X = 69
has a pvalue of 0.9564
X = 57
has a pvalue of 0.8051
0.9564 - 0.8051 = 0.1513
P(57 < X < 69) = 0.1513
Here, it is solved.
you only have to know:
The sum of the sides of a quadrilateral is equal to 360º.
(3x+9)+(x+21)=90
4x+30=90
4x=60
60/4=15
X=15
Answer:
the asymptote of the graph y = 1
Step-by-step explanation:
The asymptote of the graph y = 1 (Horizontal asymptote)
As you can see a line that a graph is approạching to as it heads towards infinity but it does not intersect.
Moreover, the value of y is decreasing over its domain. as you can see in the graph.
