Suppose 2 quarters, 3 dimes, 3 nickels, and 9 pennies are in a box. One coin is selected at random. What is the expected value o

Hoochie [10]

Answer:

Given that,

Suppose 2 quarters, 3 dimes, 3 nickels, and 9 pennies are in a box.

One coin is selected at random.

To find the expected value of the money drawn from the box.

we get,

Total number of coins is 2+3+3+9=17

Probability of getting quarter is,

$\frac{2}{17}$

Probability of getting dime is,

$\frac{3}{17}$

Probability of getting nickel is,

$\frac{3}{17}$

Probability of getting penny is,

$\frac{9}{17}$

we know that,

$\begin{gathered} 1\text{ quarter}=0.25\text{ dollars} \\ 1\text{ dime}=0.1\text{ dollars} \\ 1\text{ nickel}=0.05\text{ dollars} \\ 1\text{ penny}=0.01\text{ dollars} \end{gathered}$

Using this, we get

The expected value of the money drawn from the box is,

$=(0.25)\times\frac{2}{17}+(0.1)\times\frac{3}{17}+(0.05)\times\frac{3}{17}+(0.01)\times\frac{9}{17}$ $=\frac{0.5}{17}+\frac{0.3}{17}+\frac{0.15}{17}+\frac{0.09}{17}$ $=\frac{1.04}{17}\approx0.06117\text{ dollars}$

Let's use the slope intercept form of a line which is:

y=mx+b where m=slope and b=y-intercept.

Mathematically m=(y2-y1)/(x2-x1) and the y-intercept is just the value of y when x is equal to zero, where the line intercepts the y axis...

First you want to find the slope by finding two clearly identifiable points on the graph...I'll pick (4,4) and (0,1), now we can calculate the slope or "m"...

m=(4-1)/(4-0)=3/4 so now we can say our line is:

y=0.75x+b, using point (4,4) we can now solve for b.

4=0.75(4)+b

4=3+b

b=1 so the line is"

y=0.75x+1

Passing through(-1,8) and parallel to the line whose equation is 8x-9y-2=0

notka56 [123]

<h3>Answer:</h3>

y = 8/9x + 80/9

<h3>Step-by-step explanation:</h3>

<u>We are given;</u>

Equation of a line as 8x -9y -2 = 0
Coordinates (-1,8)

We are required to determine the equation of a line parallel to the given line and passing through a point (-1,8)

<h3>Step 1: Determine the Gradient of the given line </h3>

When an equation is written in the form y = mx + c, m is the gradient.
Therefore; we could write the equation 8x -9y -2 = 0 in the form of y= mx + c

9y = 8x -2

y = 8/9x - 2/9

Therefore, the slope, m = 8/9

<h3>Step 2: Determine the equation of the line</h3>

We need to know that parallel lines have the same gradient
Therefore, the slope of the line in question is 8/9
It passes through a point (-1, 8)

We can therefore, determine the equation;

Taking another point, (x,y)

$\frac{y-8}{x+1} = \frac{8}{9}$

9(y-8) = 8(x+1)

9y - 72 = 8x + 8

9y = 8x + 8 +72

9y = 8x + 80

y = 8/9x + 80/9

Therefore, the equation of the line is y = 8/9x + 80/9
