Rolling two dice can output any number between 2 and 12. Here are the probabilities (given by how many combinations would yield that sum):

You get 2 if you roll (1, 1) \implies P=\dfrac{1}{36}

You get 3 if you roll (1, 2), (2, 1) \implies P=\dfrac{2}{36}

You get 4 if you roll (1, 3), (2, 2), (3, 1) \implies P=\dfrac{3}{36}

You get 5 if you roll (1, 4), (2, 3), (3, 2), (4, 1) \implies P=\dfrac{4}{36}

You get 6 if you roll (1, 5), (2, 4), (3, 3), (4, 2), (5, 1) \implies P=\dfrac{5}{36}

You get 7 if you roll (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1) \implies P=\dfrac{6}{36}

You get 8 if you roll (2, 6), (3, 5), (4, 4), (5, 3), (6, 2) \implies P=\dfrac{5}{36}

You get 9 if you roll (3, 6), (4, 5), (5, 4), (6, 3) \implies P=\dfrac{4}{36}

You get 10 if you roll (4, 6), (5, 5), (6, 4) \implies P=\dfrac{3}{36}

You get 11 if you roll (5, 6), (6, 5) \implies P=\dfrac{2}{36}

You get 12 if you roll (6, 6) \implies P=\dfrac{1}{36}

So, you get an even sum OR a 3 if you roll a total of 2, 3, 4, 6, 8, 10 or 12. The sum of their probabilities is

\dfrac{1+2+3+5+5+3+1}{36}=\dfrac{20}{36}=\dfrac{5}{9}

You get doubles and at least 8 if you get (4,4), (5,5) or (6,6). Each of these pairs happen with probability 1/36, for a total of

\dfrac{3}{36}=\dfrac{1}{12}

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,
rjkz [21]

Answer:

w = \frac{1}{2}(P - 24)

w = 153\ yards

Step-by-step explanation:

Given

P = 24 + 2w

Require

Solving (a):

P = 24 + 2w

Subtract 24 from both sides

P-24 = 24-24 + 2w

P-24 = 2w

Divide both sides by 2

\frac{1}{2}(P - 24) = \frac{2w}{2}

\frac{1}{2}(P - 24) = w

w = \frac{1}{2}(P - 24)

Solving (b):

Substitute 330 for P un the expression in (1)

w = \frac{1}{2}(330 - 24)

Evaluate the bracket

w = \frac{1}{2}(306)

w = 153\ yards

What is the slope of the line created by this equation?Round your answer out to two decimal places.3x+5y=7
tia_tia [17]

The given equation is

3x+5y=7

Consider the slope-intercept form.

y=mx+b

Rewriting the given equation in the slope-intercept form.

3x+5y=7

Subtracting 3x from both sides, we get

3x+5y-3x=7-3x

Dividing both sides by 5, we get

\frac{5y}{5}=\frac{7-3x}{5}y=-\frac{3}{5}x+\frac{7}{5}

y=-0.6x+1.4

Compared to the slope-intercept form, we get m=-0.6 and b=1.4.

Hence the slope m= -0.60.
