In a state's Pick 3 lottery game, you pay $1.42 to select a sequence of three digits (from 0 to 9), such as 966. If you select t

Mumz [18]

The lottery game is an illustration of probability

The total number of different selections is 1000
The probability of winning is 0.001
The net profit of winning is $262.82
The expected earning is -$1.156

<h3>The number of selections</h3>

Each of the three selections can be any of the 1o digits 0 - 9.

So, the total number of different selections is:

$n = 10^3$

$n = 1000$

<h3>The probability of winning</h3>

Only one of the 1000 selections can win.

So, the probability of winning is:

$p = \frac 1{1000}$

$p = 0.001$

<h3>The net profit</h3>

The stake amount is given as $1.42, and the earnings per game is given as $264.25.

So, the net profit is:

Net = $264.25 - $1.42

Net = $262.82

<h3>The expected winnings</h3>

This is calculated as:

$E(x) = \sum x P(x)$

So, we have:

$E(x) = 262.82 * 0.001 - 1.42 * (1 - 0.001)$

$E(x) = -1.156$

Hence, the expected earning is -$1.156

Jelly fakes sell for $1.23 for 1/4 pound bag. How much for 4 pounds of jelly fakes?

Mkey [24]

Answer:

19.68

Step-by-step explanation:

1/4 x 16 = 4

1.23 x 16 = 19.68

so you have 1/4 of pound so you will time that by four which equals 1 pound

now with that info you times 4 x 4 3 more times to get 4 pound

but you want the price so you figure how many fours there were and time them to gt 16 then you 16 x 1.23

How do i find the x intercet for y=6x−7.

kolezko [41]

Answer:

Step-by-step explanation:

y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-6x+7 = 0 and calculate its properties.

Graph of a Straight Line

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is -7/1 so this line "cuts" the y axis at y=-7.00000

y-intercept = -7/1 = -7.00000

Calculate the X-Intercept :

When y = 0 the value of x is 7/6 Our line therefore "cuts" the x axis at x= 1.16667

x-intercept = 7/6 = 1.16667

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -7.000 and for x=2.000, the value of y is 5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.000 - (-7.000) = 12.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 12.000/2.000 = 6.000

x-intercept = 7/6 = 1.16667

y-intercept = -7/1 = -7.00000
