A gas station sells two grades of gasoline: regular and super. These are priced at $2.00 and $3.00 per gallon, respectively. Let
djyliett [7]

Answer:

(a) E(Y) = 4400

sd (Y) =225

(b)  P(Y ≤ 4500) = 0.67003

(c) P (X₁ > X₂) = 0.31744

Step-by-step explanation:

(a) Here we have

Y = 2·X₁ + 3·X₂

Therefore E(Y) = 2·E(X₁) + 3·E(X₂) = 2000 + 2400 = 4400

sd(Y) is given by

Variance Y = (sd (Y))² = 2²·(sd (X₁))² + 3²·(sd (X₂))²

= 4·8100 + 9·2025 =  50625

sd (Y) = √50625 = 225

(b) The probability that the revenue does not exceed 4500 is given by

P(Y ≤ 4500) =  P(z ≤0.444)

z = \frac{\overline{\rm x} - \mu} {\sigma /\sqrt{n} }

z = \frac{4500 - 4400} {225 /\sqrt{1} } = 0.444

Therefore from the normal distribution table, we have

P = 0.67003

(c) The probability that the P(X₁ > X₂)

Since the gas station sells 2 portions of X₁ to 3 portions of X₂

Therefore, the probability that the gas station sells more of X₁ is given by

₅C₀ × 2/5⁰×3/5⁵ = 0.07776

₅C₁ × 2/5¹×3/5⁴=  0.2592

₅C₂ × 2/5²×3/5³ = 0.3456

P (X₁ > X₂) = 1 - 0.68256 = 0.31744

. Which of the equations below has a solution of 3? A 2 r= 6 B 6 = 2 rC 2r = 6
yaroslaw [1]

Answer:

They all have a solution of 3.

Step-by-step explanation:

Each of the equations represented are basically the same thing, therefore have the same answer.

A) 2r = 6 - You would divide 6 by 2 and you would get 3.

B) 6 = 2r - You would still divide 6 by 2, which equals 3.

C) 2r = 6 - Then again you would divide 6 by 2 to get 3.
