Answer:

A.) k=0.5

Step-by-step explanation:

If we use the formula given: y=kx, we can plug in values.

0.5=k(1)

0.5=(0.5)(1)

0.5=0.5

We know that to get from 1 to 0.5, we need to divide by two, or multiple by 1/2. 1/2 in decimal form is 0.5

In the SuperLottery, three balls are drawn (at random) from ten white balls numbered from $1$ to $10$, and one SuperBall is draw

Verdich [7]

nCr(20, 2) = 190 ways of selecting 2 from 20

nCr(10, 1) = 10 ways of selecting 1 from 10

To find the over all probability of winning,

Calculate the Harmonic Mean (19) and divide by 2

Equivalent to

1/ (1//190 + 1/10) =9.5

So the probability is 1/9.5 = 2/19.

Answer:

A.) For the first inequality (y<=-3x+5) the ordered pairs are (0,5) and (1,2).

For the second inequality(8x-4y<24) the ordered pairs are (0,-6) and (1,-4).

B. (0,-7) is a solution to both inequalities.

C. (0,6) is not a solution to either inequality.

D. (0,0) is a solution for the first inequality, but not the second inequality.
