Need the answer for this

Using the expected value of a discrete distribution, it is found that the amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

In this problem, considering 6 out of 6^2 = 36 outcomes are doubles, we have that the distribution is:

P(X = 5) = 1/6.

P(X = x) = 5/6.

A fair game means that the expected value is of 0, hence:

[tex]5\frac{1}{6} - \frac{5x}{6} = 0[/tex]

[tex]\frac{5x}{6} = \frac{5}{6}[/tex]

[tex]x = 1[/tex]

The amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.

Answer:

The missing side is X=4

Step-by-step explanation:

Since the triangles are similar to eachother, they will have the same ratio.

One way to solve is dividing 8 by 2. Since 12 divided by 2 is 6,

we can expect 8 divided by 2 to be the missing side we are looking for.

Hope that helps!

Answer:

x = 4

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{x}{8}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )

12x = 48 ( divide both sides by 12 )

x = 4

Answer:

119 yds and 76 yds

Step-by-step explanation:

area of 1st rect = 9000 yd^2

perimeter = 2(75+120)= 2*195=390

perimeter of 2nd rectangle = 390

l+b = 390/2= 195

the minimum l of 2nd rectangle = 119

min b of 2nd rectangle = 76

119*76 =9044

The circumference of the circle typically means finding the perimeter of the circle. It refers to the equal arc length of the circle as though the circle is expanded and flattened out towards a line segment.

It can be determined by using the formula:

Answer:

y = 3/2x - 8  hope I helped

Step-by-step explanation:

To find the equation of a line, we need a point and a slope. We're given a point, and we can easily get the slope. First let's solve 2y = 3x + 10 for y so we can get the slope (recall that y = mx + b is the slope-intercept form, and m is your slope).

2y = 3x + 10  --> almost there already, just divide everything by 2 to get y by itself.

y = 3/2x + 5 --> now you have it in the y=mx + b form, so your slope is 3/2

They asked for the parallel line, remember parallel lines have the same slope, therefore you use the same slope.

Now we know that our slope is m = 3/2 and our point is (2, -5)

You can always find the equation of a line using the Point-Slope Formula:

y - y1 = m(x - x1)    --> our x1 is 2 and our y1 is -5, and slope is 3/2

y - (-5) = 3/2(x - 2)   --> Be careful when you have minus a negative number, like we do here. It becomes:

y + 5 = 3/2(x - 2)  --> now distribute the 3/2

y + 5 = 3/2x - 6/2

y + 5 = 3/2x - 3  --> now we can subtract 5 from both sides to get it into slope intercept form.

y = 3/2x - 8  --> This is the equation of a line that is parallel to 2y=3x+10 & passes through (2, -5)

n²-25

Expand the polynomial using the FOIL method. (A handy way to remember how to multiply two binomials. It stands for "First, Outer, Inner, Last")

Answer:

n² - 25

Step-by-step explanation:

(n - 5)(n + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

n(n + 5) - 5(n + 5) ← distribute parenthesis

= n² + 5n - 5n - 25 ← collect like terms

= n² - 25

Answer:

R=50    b=130   a=135

Step-by-step explanation:

Sum of Internal angles   = 180

R= 180-85-45 = 50

missing interior angle R  = 50

If a side of a triangle is produced, then the exterior angle that is  formed is equal to the sum of the two interior opposite angles.

P+Q = 85+45= 130     b=130

P+R = 85+50 = 135     a=135

To solve this problem, we would have to add the sum of angles in a triangle and then find the missing side. Furthermore, value of R, a and b are 50°, 135° and 130° respectively.

Data;

The sum of angles in a triangle is equal to 180° and we can find the missing side on R.

[tex]P+Q+R = 180^0\\85^0+45^0+R = 180^0\\130^0+R=180^0\\R = 180 - 130 \\R = 50^0[/tex]

Since we know the value of R and Q, we can proceed to find a and b.

[tex]Q+ a = 180\\[/tex]

The reason behind this is that the sum of angles on a straight line is equal to 180^0

[tex]45+a = 180 \\a = 180 - 45 \\a = 135^0[/tex]

Now let's find the value of b

[tex]R + b = 180\\R = 50^0\\50 + b = 180\\b = 180 - 50 \\b = 130[/tex]

From the calcuations above, the value of R, a and b are 50°, 135° and 130° respectively.

Or you can compute it like this 8*7*6*5*4*3*2 = 40320

This would be the answer if we could tell the E's apart.

However, we cannot tell the E's apart, so we have to divide by 2 to correct for the double-counting.

There are 40320/2 = 20160 different seven letter combinations possible.

Answer: It

should be about 1.5 years

Step-by-step explanation:

1.143 years must the person leave the money in the bank until it reaches 10500 dollars.

Interest, in its most simple form, is calculated as a percent of the principal.

For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.

We have,

Interest amount= $8000

R= 6.5%

Time= t

Total amount= $10, 500

So, A = P(1 + r/n[tex])^{nt[/tex]

10,500 = 8000 (1+ 0.065/4[tex])^{4t[/tex]

1.3125 =  (1.01625[tex])^{4t[/tex]

Taking log both side

log (1.3125) = 4t log(1.06125)

4t = 4.574

t= 1.143 years
