Answer:

(-1, 1)

Step-by-step explanation:

Multiply f(x) or y value by -2, so (-1, 2) -> (-1, -4)

Add 5 to the f(x) or y value since it is a vertical translation, so (-1, -4) -> (-1, 1)

ipn [44]

Answer:

a. 0.58

b. 0.78

Step-by-step explanation:

a. The probability of egg come from B1 or B2

P(B1) = 3000/10000 = 0.3

P(B2) = 4000/10000 = 0.4

P(P1 ∪ B2) = 0.3 + 0.4 -(0.3)(0.4)

P(P1 ∪ B2) = 0.7 - 0.12

P(P1 ∪ B2) = 0.58

b. The probability that the market received an egg that is acceptable

P(received an egg that is acceptable) = P(B1 acceptable) + P(B2 acceptable) + P(B3 acceptable)

P(received an egg that is acceptable) = 0.80*3000 + 0.90*4000 + 0.60*3000 / 10000

P(received an egg that is acceptable) = 2400 + 3600 + 1800 / 10000

P(received an egg that is acceptable) = 7800 / 10000

P(received an egg that is acceptable) = 0.78

1) p + 8
Substitute 2 in for the variable.
2 + 8 = $\fbox {10}$

2) 3p
Substitute 2 in for the variable.
3(2) = $\fbox {6}$

3) 16 - p
Substitute 2 in for the variable.
16 - 2 = $\fbox {14}$

4) -12 ÷ p
Substitute 2 in for the variable.
-12 ÷ 2 = $\fbox {-6}$
