At local ice cream store, you can purchase one, two, or three scoops of ice cream. you also have a choice of either a sugar cone or a waffle cone. based on the average daily sales from the past week, 60% of the customers purchase a waffle cone, 40% of the customers purchased two scoops of ice cream, and 20% purchased both. based on the average daily sales from last week, what is the probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone?

33.3% probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone.

Step-by-step explanation:

In this problem, we have these following probabilities:

A 60% probability that a customer purchases a waffle cone.

A 20% probability a person person purchases both a waffle cone and two scoops of ice cream.

Based on the average daily sales from last week, what is the probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone?

This is 0.2/0.6 = 0.333 = 33.3% probability a randomly selected customer purchases two scoops of ice cream if we know the customer purchased a waffle cone.

answer: 48

just remember to use pemdas:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
