1) at joe's restaurant, one-fourth of the
patrons are male and one-fifth of the
patrons are from out of town. what
proportion would you expect to be
male and out of town?

1/20 of the patrons at Joe's restaurant are expected to be male and out of town.

Step-by-step explanation:

1. Let's review all the information provided for solving this question:

Proportion of patrons that are male at Joe's restaurant = 1/4

Proportion of patrons that are from out of town at Joe's restaurant = 1/5

2.  What  proportion would you expect to be  male and out of town?

For finding the proportion of the patrons, that would be male and that would be from out of town, we do this calculation:

Proportion of patrons that are male at Joe's restaurant * Proportion of patrons that are from out of town at Joe's restaurant

1/4 * 1/5 = 1/20

It means that 1/20 of the patrons at Joe's restaurant are expected to be male and out of town.

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
