Events A and B are mutually exclusive, with P(A) = 0.36 and P(B) = 0.05.
What is P(A or B)?
A.0.018 B.0.31 C.0.41 D.0.86

Answers

Answer 1

Answer: Since A an B are mutually exclusive, you can just add the two probabilities. Mutually exclusive means that one does not depend at all on the other.

A theater has 43 seats in the first row. There are 49 seats in the second row, 61 seats in the third row, and 79 seats in the fourth row. If this pattern continues, how many seats are in the seventh row?

Answers

43 to 49 is 6
49 to 61 is 12
61 to 79 is 18
add 6 to each
79=4th row
79+18+6=79+24=103
103+24+6=103+30=133
133+30+6=133+36=169

7th row=169 seats

A large container holds 5 gallons of water. it begins leaking at a constant rate. After 10 minutes the container has 3 gallons of water left. at what rate is the water leaking?

Answers

The required rate of water leaking is 0.2 gallons of water per minute.

Given that,

A large container holds 5 gallons of water. it begins leaking at a constant rate. After 10 minutes the container has 3 gallons of water left. at what rate is the water leaking is to be determined.

What is the rate of change?

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,
Total volume = 5 gallons
Volume left after 10 min = 3 gallons
Rate = [total volume - volume left] / 10
rate = 5 - 3 / 10
Rate = 2 / 10
Rate = 0.2

Thus, the required rate of water leaking is 0.2 gallons of water per minute.

#SPJ2

First we have to find how much water leaked
5galllons-3 gallons=2 galllos of water leaked
Now we know $(2 galllons)/(10 minutes)$
Finally we can simplify it $(2 gallons)/(10 minutes)= (1 gallon)/(5 minutes)$ - its the answer

The tables shows the sizes and colors of t shirts sold over the past week, To the nearest percent what is the experimental probability that the next customer who buys a t-shirt at the store will buy a large blue t-shirt? Explain how you solved that problemSmall Medium Large
white 32 49 28
blue 12 36 20
Black 20 42 23

Answers

Probability is defined as the fraction, where the numerator is the number of favorable events (in this case number of large blue t-shirts, which is 20 in the table) and the denominator is the number of ALL possible events (in this example it is the sum of all sold t-shirts, when you sum up all the data in the table, you get total of 262 t-shirts).
So, probability that the next t-shirt (large blue) to be sold is:
P = 20/262 = 0.076335877....
which is approximately 0.08 (when rounding to 2 decimal places).
We obtain the percentage of large blue t-shirt being sold next:
P = 8%

At a party, 70 people are right-handed and 12 people are left-handed. What is the ratio of right-handed people to the total? (Reduce your answer to lowest terms.)

Answers

The correct answer would be 35 to 41 or 35:41. You just put the 70 in the front because you find the ratio first of the right-handed people. Then put the total, which is 70+12, which equals 82. Now, it's 70 to 82. It can be simplified to 35 to 41. Finally, you got the answer, which is: 35 to 41.
Hope this helps. :-)

Final answer:

The ratio of right-handed people to total people at the party is calculated by dividing both the number of right-handed people and the total number of people by their greatest common divisor (GCD). In this case, the ratio in simplest form is 35:41.

Explanation:

To answer this question, one needs to understand the concept of ratios. In this case, we are looking for the ratio of right-handed people to the total number of people at the party.

Start by adding the number of right-handed and left-handed people to get the total number of people: 70 (right-handed) + 12 (left-handed) = 82 (total).

The next step involves setting up the ratio. The number of right-handed people (70) is set over the total number of people (82). So, the ratio is 70:82.

To reduce the ratio to lowest terms, you find the greatest common divisor (GCD) of both numbers. The GCD of 70 and 82 is 2. Divide both numbers by their GCD to get the ratio in simplest form: 70 ÷ 2 = 35 and 82 ÷ 2 = 41. Therefore, the ratio of right-handed people to the total number of people at the party in simplest form is 35:41.
