The local fire company is having a raffle to raise money for Fourth of July fireworks. They will sell one thousand tickets at $1

Anestetic [448]

Answer:

The expected value of a ticket is of -$5.

Step-by-step explanation:

The expected value of the ticked is the probability of earning each prize multiplied by the prize, and subtracted by the value of the ticket.

Value of the ticket:

$10.

100 tickets are sold. They will award one first prize of $300, one second prize of $150, and one third prize of $50.

Thus, 1/100 probability of earning $300, 1/100 probability of 150 and 1/100 probability of 50. So

$E = \frac{1}{100}300 + \frac{1}{100}150 + \frac{1}{100}{50} - 10 = 3 + 1.5 + 0.5 - 10 = -5$

The expected value of a ticket is of -$5.

2d=a-b/b-c - solve for a

Readme [11.4K]

$2d=\frac{a-b}{b-c}\\\\\frac{a-b}{b-c}=2d\ \ \ \ \ |multiply\ both\ sides\ by\ (b-c)\\\\a-b=2d(b-c)\ \ \ \ |add\ "b"\ to\ both\ sides\\\\\boxed{a=2bd-2cd+b}$

Write an equation in slope-intercept form for the line that satisfies the following condition.

AlexFokin [52]

Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]

For lines to be parallel, they have to have the same slope

y = x + 7

m = 1 So the parallel line's slope is also 1

y = mx + b

y = x + b To find b, plug in the point (8, 10) into the equation

10 = 8 + b Subtract 8 on both sides

2 = b

y = x + 2
