Answer:
0.7486 = 74.86% observations would be less than 5.79
Step-by-step explanation:
I suppose there was a small typing mistake, so i am going to use the distribution as N (5.43,0.54)
Problems of normally distributed samples can be 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.
The general format of the normal distribution is:
N(mean, standard deviation)
Which means that:

What proportion of observations would be less than 5.79?
This is the pvalue of Z when X = 5.79. So



has a pvalue of 0.7486
0.7486 = 74.86% observations would be less than 5.79
(8.4 / 6) + 3.2
Hope this helps :)
Answer:
1,224 feet
Step-by-step explanation:
Multiply 51 feet times 24 feet and then you get 1,224 ft.
Answer 1029
Step-by-step explanation: So, since all of the phones cost 3,069 in total, divide 3,069 by three. You get 1029.
1/40 would be your answer because 0.025 is would be 25/1000. Simplify that then you would get 1/40.
