In a fund-raising game for your school, you bet $1 to roll two dice. If your total is 8,9,10 or 11 you win $2. If your total is

ololo11 [35]

Answer: E , You will lose 5.6 cents

Step-by-step explanation:

Because with two dice, there are 36 possible outcomes, 21 are 7 or less, 14 are 8 through 11, and 1 is twelve.

Also when you have a total of 8,9,10 or 11, you gain $1 deducing the $1 you bet. The same with when you have 12 you gain $5.

Average $ to gain when total is 8,9,10 or 11 = P(8,9,10,11)

P(8,9,10,11) = ($2-$1)(14/36) = $14/36 gain

P(12) = ($6-$1)(1/36) = $5/36 gain

P(7 or less) = (0-$1)(21/36) = -$21/36 loss

P(loss or gain)= P(8,9,10,11) + P(12) + P(7 or less)

P(loss or gain) = $( 14/36 + 5/36 - 21/36) = -$2/36

P(loss or gain) = -$0.056 = -5.6 cents loss

Therefore, For every $1 bet you will lose 5.6 cents.

Write the formula for slope, for the point-slope

Brut [27]

Slope: M = rise/run = y2 - y1/x2 - x1

Point slope: y-y₁=m(x-x₁)

Slope-intercept: y = mx+b

The length of a rectangle is two less than four times the width. If the perimeter is 26 cm, find the dimensions of the rectangle

gulaghasi [49]

Answer:

w = 3

l = 10

Step-by-step explanation:

l = 4w-2

P = 26cm

P = (l + w) × 2

26 = (4w-2+w) ×2

26 = (4w + w - 2) × 2

26 = ( 5w - 2 ) × 2

26 ÷ 2 = 5w -2

13 = 5w - 2

13 + 2 = 5w

15 = 5w

w = 3

l = 4w - 2

l = (4 × 3) -2

l = 12 - 2

l = 10

Write an equation in slope intercept form for the line with slope negative three fourths and y intercept of negative one

Stells [14]

The slope intercept form is $y=-\frac{-3x}{4}-1$ .

Solution:

Given data: slope = $-\frac{3}{4}$ and y-intercept = –1

y-intercept means (x, y) = (0, –1)

Equation of a line for slope intercept form: $y-y_1=m(x-x_1)$

Here, $x_1=0, y_1=-1$ and $m=-\frac{3}{4}$ .

⇒ $y-(-1)=\frac{-3}{4} (x-0)$

⇒ $y+1=\frac{-3}{4} (x)$

Do cross multiplication.

⇒ $4(y+1)=-3x$

⇒ $4y+4=-3x$

⇒ $4y=-3x-4$

Divide both sides of the equation by 4.

⇒ $y=-\frac{-3x}{4}-\frac{4}{4}$

⇒ $y=-\frac{-3x}{4}-1$

Hence the slope intercept form is $y=-\frac{-3x}{4}-1$ .
