The coefficient of "-x" is: "-1" {"negative one"},
For "stand alone" variable, with coefficients of "1" or "-1", we often OMIT the "1" or "-1"; and just use the "+" (positive sign); or leave as written for positive;
and just use the " - " (negative sign; with the "1", for negative);
since any value multiplied by "1" is that same value; so the omitted "1" (or "-1"); in implied.
2x - 3 = 6
2x = 6 + 3
2x = 9
x = 9/2
x = 4.5
The value of x is 4.5
Answer:
A player can expect to win an average of 0.70 per lottery after playing the lottery sufficiently many times.
Step-by-step explanation:
The expected value for the amount of money to be won is 0.70 ;
The expected value of expected mean simply means the long run average because the expected mean refers to the average value of a random variable which is which is obtained over a large number of trials or experiment. In the case of lottery game, expected will thus be interpreted to mean the average winning (or loss) expected which a player earns or incurs after playing the lottery many times. It differs from the mean or average value earned after playing just a game or two as it refers to a long run average.
Well the slope would be m=-5/4 and the y-intercept would be 1 because of y=mx+b
