1 lb / 0.45 = 2.22

 so approximately 2.22 kilograms per pound

 divide price per pound by kilometers per pound

1.44 / 2.22 = 0.648

 round to 0.65, so it costs $0.65 per kilogram

on a standardized exam the scores are normally distributed with a mean of 70 and a standard deviation of 20. find the z of a per
KIM [24]

The z-score of a person who scored 128 on the exam is equal to 2.9

<h3>What is a z-score?</h3>

A z-score is also referred to as a z-value or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.

Mathematically, the z-score of a given sample score in a normal distribution can be calculated by using this formula:

z=\frac{x\;-\;u}{\sigma}

Where:

  • x represents the sample score.
  • u represents the mean score.
  • σ represents the standard deviation.

Substituting the given parameters into the formula, we have;

Z-score, z = (128 - 70)/(20)

Z-score, z = 58/20

Z-score, z = 2.9
