Thank you guys soo much

Answer:

20 rides.

The question:

"There have been two proposals for ticket sales. The first proposes a base fee of $5 for entry into the park and $0.50 per ride. The second plan has no base fee, but charges $0.75 per ride. After How many rides would the cost[s] be equal?"

Step-by-step explanation:

Assume that the two costs become equal after $x$ rides.

The first plan will cost $(5 + 0.50x)$ dollars.
The second plan will cost $0.75 x$ dollars.

The two costs are assumed to be equal. That is:

$5 + 0.50x = 0.75 x$ .

Subtract $0.50x$ from both sides of this equation:

$5 = 0.25 x$ .

$\displaystyle x = \frac{5}{0.25} = \frac{500}{25} = 20$ .

In other words, the two costs become equal after 20 rides.

emmainna [20.7K]

Hey there! I'm happy to help!

Let's call the number of weeks w. Since we want their balances, to be equal, we can create an equation.

1000-55w=800-30w

Now we solve for w. We add 30w to both sides.

1000-25w=800

Subtract 1000 from both sides.

-25w=-200

Divide both sides by -25.

w=8

Therefore, Mark and Patricia will have the same amount of money in their savings accounts after 8 weeks.

Have a wonderful day! :D

The probability a household in a community uses gas for cooking is 0.18. If a shopper from the community is from a household tha

Lyrx [107]

Answer:

The probability of a person from the community not shopping at Prime Foods given that he uses gas for cooking at his household is 0.092

Step-by-step explanation:

Hello!

Given the information:

A: "The household uses gas for cooking" ⇒ P(A)= 0.18

B: "The person from the comunity shops at Prime Foods"

The person shops at Prime Foods given that he uses gas for cooking:

P(B/A)= 0.7

The person shops at Prime Foods given that he doesn't use gas for cooking:

P(B/Ac)= 0.35

If the person doesn't shop at Prime Foods, what is the probability that he uses gas for cooking?

Symbolically:

P(A/Bc) = P(A∩Bc)

P(Bc)

The event Bc is the complement of event B, so it's probability is P(Bc)= 1 - P(B)

You can calculate the probability of B as:

P(B)= P(A∩B)+ P(Ac∩B)

Using the information of P(B/A)= 0.7 and P(B/Ac)= 0.35 you can reach the values of both intersections.

P(B/A)= P(A∩B)

P(A)

P(B/A)*P(A)= P(A∩B)

P(A∩B)= 0.7*0.18= 0.126

and

P(B/Ac)= P(Ac∩B)

P(Ac)

If A and Ac are complementary events, then P(Ac)= 1 - P(A)= 1 - 0.18= 0.82

Then:

P(B/Ac)*P(Ac)= P(Ac∩B)

P(Ac∩B)= 0.35*0.82= 0.287

The probability of B is:

P(B)= P(A∩B)+ P(Ac∩B)= 0.126+0.287= 0.413

P(Bc)= 1 - P(B)= 1 - 0.413= 0.587

And

P(A)= P(A∩B)+P(A∩Bc)

P(A∩Bc)=P(A)=-(A∩B)= 0.18-0.126= 0.054

Finally:

P(A/Bc) = P(A∩Bc) =0.054 = 0.0919≅ 0.092

P(Bc) 0.587

I hope it helps!
