<u>Fill in the table:</u>

Heads | 2 ⇒ 4 ⇒ 6⇒ 8 ⇒ 10 ⇒ 12
Tails | 1 ⇒ 2 ⇒ 3 ⇒ 4 ⇒ 5 ⇒ 6

b)

The score of 4 is obtained in 2 cases out of 12 as per above table.

<u>The probability is:</u>

p(4) = 2/12 = 1/6

c)

The score of 10 is obtained once in 12 cases as per table.

<u>The probability is:</u>

p(10) = 1/12

<u>Out of 60 times he can score 10:</u>

60*1/12 = 5 times

Find the slope of the line that passes through (3, 2) and (7,5)

Bas_tet [7]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Slope is equal to the change in y over the change in x.

$m = \frac{change \: in \: y}{change \: in \: x}$

The change in x is equal to the difference in x-coordinates, and the change in y is equal to the difference in y-coordinates .

$m = \frac{y2 - y1}{x2 - x1}$

Substitute in the values of x and y into the equation to find the slope.

$m = \frac{5 - (2)}{7 - (3)}$

Simplify.

$m = \frac{3}{4}$

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>slope</u><u> </u><u>is</u><u> </u><u>3</u><u>/</u><u>4</u><u>.</u>

2. What is the x-value to the solution for the system of equations y = -5x - 9 and y = 2x<br> + 5.

pav-90 [236]

Answer:

The x-value is -2

Step-by-step explanation:

U can substitute any of the equations for y

-5x + (-9) = 2x + 5

-9 = 7x + 5

-14 = 7x

-2 = x

x = 2
