The total bill at a restaurant was $58.25 and included a $12 tip for the server. what was the average spent per person prior to the tip if there were 3 people at the dinner?

Let x = cost of bill prior to tip

So, we know that before a tip was paid that the cost of the meal was $46.25. If there were three people at the dinner and we are trying to find the average spent prior to the tip, we can just divide.

Let a = average each person spent

On average, prior to the bill, each person paid approximately $15.42.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
