Answer:

Step-by-step explanation:

-3 = 2x+6y

2x+6y = 0

By transitivity, -3 = 0, a contradiction. No solution.

If you graph the lines, you will see they are parallel, therefore never intersect.

Two counters are selected at random from a bag containing 5 red counters and 3 blue counters.

azamat

Answer:

1.4

Step-by-step explanation:

Probability of selecting a red counter :

Number of red counter / total number of counters

5 / (5 + 3) = 5 /8 = 0.625

Probability of selecting a blue counter = 0.375

Let number of red counters :

0, 1 or 2

0 red counters :

Expected value = x * p(x)

0 + (0.625*1) + (0.390625 * 2)

0 + 0.625 + 0.78125 = 1.40625

Expected number of red counters = 1.4

Answer:

$a = 0$

Step-by-step explanation:

On the right side of the = multiply -4 through

$- 6a - 4 = - 4 - 28a$

add 28a and add 4 to both sides

$28a - 6a = 4 - 4$

$22a = 0$

divide both sides by 22

$a = 0$
