The state lottery board is examining the machine that randomly picks the lottery numbers. On each trial, the machine outputs a ball with one of the digits 0
through 9 on it. (The ball is then replaced in the machine.) The lottery board tested the machine for 40 trials and got the following results.
0 1 2 3 4 5 6 7 8 9
Number of Trials 7 3 5 2 7 3 2 1 46
Fill in the table below. Round your answers to the nearest thousandth.
Outcome
(a) Assuming that the machine is fair, compute the theoretical probability of getting a 0.
(b) From these results, compute the experimental probability of getting a 0.
0
(C) Assuming that the machine is fair, choose the statement below that is true:
The experimental and theoretical probabilities must always be equal.
As the number of trials increases, we expect the experimental and theoretical
probabilities to become closer, though they might not be equal.
As the number of trials increases, we expect the experimental and theoretical
probabilities to become farther apart.

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
