Consider the following pair of equations:
Aloiza [94]
Y = 3x + 3 this is equation 1
y = x -1 this is equation 2
since equation 1 and 2 already defined y in terms of x, we're just gonna substitute y into the other equation. as 2 is shorter I'm going with that today
x - 1 = 3x +3
-1 - 3 = 3x - x
-4 = 2x
x = -2
now we've got x just sub it in equation 2
y = -2 -1
y = -3
so the answer is (-2,-3)

The table below gives the distribution of milk
coldgirl [10]

Answer:

0.16

Step-by-step explanation:

Step 1:

Data obtained from the question. This include:

Probability of brown, P(Br) = 0.13

Probability of red, P(R) = 0.13

Probability of yellow, P(Y) = 0.14

Probability of green, P(G) =..?

Probability of orange, P(O) = 0.2

Probability of blue, P(B) = 0.24

Step 2:

Determination of the probability of green candy

Space = {brown, red, yellow, green, orange, blue}

Probability of sampl space, P(S) = 1

P(S) = P(Br) + P(R) + P(Y) + P(G) + P(O) + P(B)

1 = 0.13 + 0.13 + 0.14 + P(G) + 0.2 + 0.24

1 = 0.84 + P(G)

Collect like terms

P(G) = 1 – 0.84

P(G) = 0.16

Therefore, the probability of green candy is 0.16
