Maria plans to rent a boat. The boat rental costs $60

Mathematics

In this question, we're trying to find how many hours Maria can rent the boat for.

We know that the boat rental costs $60 per hour

We also know that she has to pay a one-time fee of $10 for a safety course

Turn this into a equation:

y = 60x + 10

However, she doesn't want to spent no more than $230. Add that to your equation

230 = 60x + 10

Solve the equation to see how many hours she can rent the boat for.

230 = 60x + 10

Subtract 10 from both sides

220 = 60x

Divide both sides by 60

3.67 = x

Since the boat can ONLY be rented by whole hours. With the money Maria has, she can only rent the boat for 3 hours.

Answer:

3 hours

A and B are two events. Let P(A)=0.5 , P(B)=0.9 and P(A and B)=0.15 .
Nana76 [90]

Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

P(A|B)=\frac{P(Aand B)}{P(B)}

now, we can plug values

P(A|B)=\frac{0.15}{0.9}

P(A|B)=0.16666

but we have

P(A)=0.5

we can see that both are not equal

P(A|B)\neq P(A)

so, A and B are not independent

so, option-C........Answer

Answer:

0.182 probability that the Yankees will win when they score fewer than 5 runs

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem:

When the Yankees score less than 5 runs, either they win, or they lose. The sum of these probabilities is 1.

Probability they lose:

Event A: Scoring fewer than 5 runs.

Event B: Losing

The probability that the Yankees will score 5 or more runs in a game is 0.56.

So 1 - 0.56 = 0.44 probability the Yankees score fewer than 5 runs.

This means that P(A) = 0.44

The probability that the Yankees lose and score fewer than 5 runs is 0.36.

This means that P(A \cap B) = 0.36

Then the probability they lose is:

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.36}{0.44} = 0.818

Probability they win:

p + 0.818 = 1

p = 0.182

0.182 probability that the Yankees will win when they score fewer than 5 runs

Solve the system using elimination. –10x – 3y = –18 –7x – 8y = 11
Naily [24]

ANSWER

x=3, y=-4

EXPLANATION

The given system is :

First equation:

- 10x -  3y =  - 18

Second equation:

- 7x - 8y = 11

Let us multiply the first equation by 7 to get,

Third equation;

- 70x - 21y =  - 126

Let us multiply the second equation too by 10 to get,

Fourth equation:

- 70x - 80y = 110

Subtract the fourth equation from the third equation:

- 21y + 80y =  - 126 - 110

59y =  -236

Divide both sides by 59.

y =  - 4

Put y=-4 into the second equation and solve for x.

- 7x - 8( - 4) = 11

- 7x + 32 = 11

- 7x = 11 - 32

- 7x =  - 21

x = 3

The solution is x=3, y=-4
