Answer:

14/81

Step-by-step explanation:

The probability of getting a green is number of green sections ÷ total number of sections = 2/4+3+2 = 2/9

Probability of not getting a green is = 1 - probability of getting a green = 1 - 2/9 = 7/9

Now we calculate the probability of not getting 2 consecutive greens. I.e probability of getting a green the first time and not getting it the second time= (2/9 × 7/9) = 14/81

Answer:

$\huge\boxed{A.\ f^{-1}(x)=\dfrac{x-3}{5}}$

Step-by-step explanation:

$f(x)=5x+3\to y=5x+3\\\\\text{exchange}\ x\ \text{with}\ y\\\\5y+3=x\\\\\text{solve for}\ y\\\\5y+3=x\qquad|\text{subtract 3 from both sides}\\\\5y+3-3=x-3\\\\5y=x-3\qquad|\text{divide both sides by 5}\\\\\dfrac{5\!\!\!\!\diagup y}{5\!\!\!\!\diagup}=\dfrac{x-3}{5}\\\\y=\dfrac{x-3}{5}\to f^{-1}(x)=\dfrac{x-3}{5}$

Sam needs to rent a car for a one-week trip to Oregon. He is considering two companies

Mariulka [41]

At 900 miles, the cost for the two rentals will be same.

Step-by-step explanation:

Given,

A+ Auto rental: $175 plus $0.10 per mile

Let,

x be the number of miles.

y be the total distance.

y = 0.10x+175 Eqn 1

Zippy Auto rental: $220 plus $0.05 per mile

y = 0.05x+220 Eqn 2

When Eqn 1 = Eqn 2, the cost will be same

Therefore;

$0.10x+175=0.05+220\\0.10x-0.05x=220-175\\0.05x=45\\$

Dividing both sides by 0.05

$\frac{0.05x}{0.05}=\frac{45}{0.05}\\x=900$

At 900 miles, the cost for the two rentals will be same.
