A motercycle can travel 60 miles per gallon. approximently how many gallons of fuel will the motercycle need to travel 40 km
miss Akunina [59]

Answer:

D. 0.42

Step-by-step explanation:

First, convert 40 km to miles by dividing it by 1.6:

40/1.6

= 25

Create a proportion where x is the number of gallons the motorcycle will need to travel 40 km (25 miles):

\frac{60}{1} = \frac{25}{x}

60x = 25

x = 0.4166

Round this to the nearest hundredth:

x = 0.42

So, to travel 40 km, the motorcycle will need 0.42 gallons of fuel.

The correct answer is D. 0.42

Suppose that the walking step lengths of adult males are normally distributed with a mean of 2.5 feet and a standard deviation o
Hitman42 [59]

Answer:

0.0668 = 6.68% probability that an individual man’s step length is less than 1.9 feet.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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.

Normally distributed with a mean of 2.5 feet and a standard deviation of 0.4 feet.

This means that \mu = 2.5, \sigma = 0.4

Find the probability that an individual man’s step length is less than 1.9 feet.

This is the p-value of Z when X = 1.9. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{1.9 - 2.5}{0.4}

Z = -1.5

Z = -1.5 has a p-value of 0.0668

0.0668 = 6.68% probability that an individual man’s step length is less than 1.9 feet.
