Answer:
The answer is D.) 1:6, 7:36, 2:9
Step-by-step explanation:
I pretty just put these into decimal form. (Dividing the numerator by the denominator)
So 1:6 is equal to .166
7:36 is equal to .199
And finally, 2:9 is equal to .222
The bigger the number, the greater it is.
Answer:
208
Step-by-step explanation:
14+2+2=18
18*12=216 - 8=208ft
2*2=4*2 because there are two little indents. I really hope that's right! If not please tell me.
The answer could look sumn like this 4+n(3)
Answer:
The travel time that separates the top 2.5% of the travel times from the rest is of 91.76 seconds.
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 80 seconds and a standard deviation of 6 seconds.
This means that 
What travel time separates the top 2.5% of the travel times from the rest?
This is the 100 - 2.5 = 97.5th percentile, which is X when Z has a p-value of 0.975, so X when Z = 1.96.




The travel time that separates the top 2.5% of the travel times from the rest is of 91.76 seconds.
