Question

Jaime is preparing for a bicycle race. His goal is to

Answer 1

Using the mean concept, it is found that the inequality can be used to  represent the number of miles, x, Jaime could bicycle  on the 4th week to meet his goal is:

$\frac{240 + 310 + 320 + x}{4} \geq 280$

The mean of a data-set is the sum of all observations divided by the number of observations.

In this problem:

• There are 4 observations.

• They are: 240, 310, 320 and x.

Hence, the mean is:

$M = \frac{240 + 310 + 320 + x}{4}$

His goal is to  bicycle an average of at least 280 miles per week for  4 weeks, hence:

$M \geq 280$

$\frac{240 + 310 + 320 + x}{4} \geq 280$
