A man mixed 2 teaspoons of sugar into his large coffee but then added one more teaspoon of sugar because it was not sweet enough
PIT_PIT [208]

Answer:

the ratio of teaspoons of sugar to one large coffee is 3: 1

Step-by-step explanation:

The computation of the ratio of sugar teaspoons to one large coffee is as follows:

Sugar teaspoons = 2 + 1 = 3

And, the one large coffee = 1

So, based on the above information

The ratio between them is

= 3:1

= 3 to 1

hence, the ratio of teaspoons of sugar to one large coffee is 3: 1

The heights of male are normally distributed with mean of 170 cm and standard deviation
Bumek [7]

Answer:

0.0918 = 9.18% probability that a randomly selected male has a height > 180 cm.

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.

Mean of 170cm and standard deviation of 7.5 cm.

This means that \mu = 170, \sigma = 7.5

Find the probability that a randomly selected male has a height > 180 cm.

This is 1 subtracted by the pvalue of Z when X = 180. So

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

Z = \frac{180 - 170}{7.5}

Z = 1.33

Z = 1.33 has a pvalue of 0.9082

1 - 0.9082 = 0.0918

0.0918 = 9.18% probability that a randomly selected male has a height > 180 cm.
