Answer:

  A.  (5, 9)

Step-by-step explanation:

The first equation tells you x=5, so the only viable choices are A and C.

The second equation tells you ...

  y = 2·5 -1 = 10-1 = 9

so the only viable choice is A.

  (x, y) = (5, 9) . . . . . matches choice A

Write the equation of a line whose slope is -2 and goes through the point (1,-1)
scoundrel [369]

Answer:

y= -2x+1

Step-by-step explanation:

y=mx+b

Substitute the ordered pairs into the equation

So:

y= -1   m(slope) = -2  x=1   b=?

-1 = (-2)(1) + b

-1 = -2 +b  add 2  on both sides to get b by itself

-1 +2 = b

b=1

Xelga [282]

The probability of the event that the number picked is less than or equal to 16 is 33.33%. Then the probability of the complement of event A is 66.67%.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A number is randomly selected from {15, 16, 17, 18, 19, 20}.

A is represented by the event that the number picked is less than or equal to 16.

Total event = 6 {15, 16, 17, 18, 19, 20}

Favorable event = 2 {15, 16}

Then the probability of the event that the number picked is less than or equal to 16 will be

\rm P(x\leq 16) = \dfrac{2}{6}\\\\P(x\leq 16) = \dfrac{1}{3} \\\\P(x\leq 16) = 0.3333\\\\ P(x\leq 16) = 33.33 \ \%

The probability of the complement of event A will be

\rm P(x > 16) = \dfrac{4}{6}\\\\P(x > 16) = \dfrac{2}{3} \\\\P(x > 16) = 0.6667\\\\ P(x > 16) = 66.67\ \%

The probability of the complement of event A is 66.67%.
