Answer:
(21, 7)
because the x axis is the number of minutes and the y axis is the x axis divided by 3
Answer:
8√0.2
Step-by-step explanation:
using Pythagoras Therom
(68)^2 = (60)^2 + (x)^2
4624 = 3600 + x^2
4624/3600 = x^2
1.28 = x^2
√1.28 = x
x = 8√0.02
√18
Separate it into its greatest factor that’s a perfect square and it’s other factor
In this case the best choice is 9 and 2
√9 √2
Simplify the perfecto square to get the answer
3 √2
√

Answer:
C = 75 in
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 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.
Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in.
This means that
Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team.
This is the 100 - 2.5 = 97.5th percentile, which is X when Z has a pvalue of 0.975, so X when Z = 1.96.
Rounded to the nearest inch,
C = 75 in
