What are the two ordered pairs for 5x=-1

Answers

5x = -1

x = -1/5 = -0.2

That means that any ordered pair for the line will be (-0.2, y)

You can put any number in for y.

So two ordered pairs could be:

(-0.2, 1)
and
(-0.2, 2)

Find the value of x in each case:

Answers

Step-by-step explanation:

BFE + BFG = 180 => Sum of angles on a

straight line

BFE = 180 - BFG

= 180 - 147

= 33

BED + BEF = 180 => Sum of angles on a

straight line

BEF = 180 - BED

= 180 - 4x

EBF + BFE + BEF = 180 => Sum of angles in a

triangle

x + 33 + (180 - 4x) = 180

x + 33 + 180 - 4x = 180

x - 4x + 33 + 180 = 180

-3x + 213 = 180

-3x = 180 - 213

-3x = -33

x = -33/-3 = 11

x = 11

Answer:

x=11 degrees :)

You roll a pair of fair six-sided dice. The sample space of 36 possible outcomes is shown below. Based on this information, answer the following questions.

Answers

Answer:

All the 36 outcomes are equally likely.

Step-by-step explanation:

The sample space of rolling a single six-sided dice is:

S = {1, 2, 3, 4, 5, 6}

Then the sample space of rolling a pair of six-sided dice is:

S₁ = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)

        (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)

        (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)

        (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)

        (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)

        (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

All the 36 outcomes are equally likely, i.e. all the outcomes has the same probability of success, (1)/(36).
