The probability of choosing one of them is 2 out of 75 while the probability of choosing the other one is 1 out of 74. 74 band members, not counting the other person (you or your bother).
Computation:
P = 2 / 75 * 1 / 74
= 0.0266... * 0.01351...
= 1 / 2,775
You can also multiply 75 with 74 to get a total of 5,550 then divide it by 2 students to be selected to get 2,775. Meaning one out of 2,775 possibilities.

Question: How to multiply fractions?
Answer: well, in order to multiply fractions, you need to simply the particular fraction with the lowest terms (if they have any of course), then we multiply our numerators from each other so we can get a brand new numerator. (you do the same thing with denominators.
Example:
[tex] \frac{6}{8} ( \frac{6}{7} ) \\ \\ \frac{6(6)}{8(7)} \\ \\ 6(6) =36 \\ \\ 8(7) = 56 \\ \\ \\ Answer: \frac{36}{54}[/tex]
Good luck on your assignment and enjoy your day!

Hello There!
To multiply fractions, you first want to line up the numerator and the denominator together so they line up with each other.
Next, you want to multiply across. This includes multiplying the numerators together and then multiplying the denominators together.
Finally, you want to find the greatest common factor but only if the fraction can be simplified.

Enter a recursive rule for the geometric sequence. 4, −16, 64, −256, ...
Answers
Answer:
The recursive rule is an = (-4) · an-1
Step-by-step explanation:
* Lets explain recursive formula for a geometric sequence:
1. Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
2. Find the common ratio. (The number you multiply or divide.)
3. Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
# a1 = first term;
# an= r • an-1
- Where:
a1 = the first term in the sequence
an = the nth term in the sequence
an-1 = the term before the nth term
n = the term number
r = the common ratio
Ex: {3, 6, 12, 24, 48, 96, ...}
first term = 3, common ratio = 2
The recursive formula an = 2 · an-1
* In our problem:
- a1 = 4
- r = -16/4 = -4
- The recursive rule is
# an = (-4) · an-1

(1 point) Question 9 options: 1) 0.09 2) 0.29 3) 0.30 4) 0.37
Answers
Answer:
4) 0.37
Step-by-step explanation:
If the principal randomly selects a student in grade 10 from this survey, the probability that the student is opposed to extending the school day is a division of the number of students that opposed from 10 Grade by the total number of students of the 10 Grade.
The table of the question is as:
Grade In favor Opposed Undecided
9 6 4 8
10 10 11 9
11 12 15 11
12 15 6 14
So, there are 10 students in 10 grade that are in favor of the extended school day, 11 students that are Opposed and 9 students that are undecided about the extended school day. then, there are 30 student in 10 Grade
Then, the probability is:

A mathematical expression that compares one number to another is called a ____.
Answers
A mathematical expression that compares one number to another is called a ratio or proportion, which includes concepts such as inequalities and proportional relationships.
A mathematical expression that compares one number to another is called a ratio or proportion. Ratios express the relationship between two quantities, while a proportion indicates that two ratios are equivalent. For example, the expression 1/2 = 3/6 signifies a proportion because the two ratios 1/2 and 3/6 are equivalent. A unit rate is a specific kind of ratio where one of the measurements is 1, such as 55 miles per hour (55/1 miles/hour). Additionally, there are other mathematical expressions used for comparison, such as inequalities, which show how two values differ, or the concept that one value 'x' is proportional to another, often used in scientific and engineering contexts.

If a household has at least one cat, there is a 30% probability that the household has at least one dog. thirty percent of households have at least one cat and 33% of households have at least one dog. given that a household does not have at least one dog, the probability that the same household does not have at least one cat is
Answers
The probability that a household does not have a cat, given that it doesn't have a dog is 70%. This is a question about conditional probability, and can be solved by applying Bayes theorem and the concept of complements in probability.
Explanation:Given the question, we need to calculate the probability that a household does not have a cat if it is known that the same household does not have a dog. This question applies to the concept of conditional probability in mathematics.
Let's consider the event of a household having at least one cat as C and the event of a household having at least one dog as D. The question tells us that the probability of a household having a dog given it has a cat P(D|C) = 0.30 and the probability of a household having a cat P(C) = 0.30, and the probability of having a dog P(D) = 0.33. We are asked to find the probability of a house not having a cat given it does not have a dog, P(C'|D').
Using Bayes theorem, the conditional probability P(C'|D') can be calculated using the formula: P(C' | D') = P(D' | C') * P(C') / P(D'), where P(C') is the probability of not having a cat and P(D'| C') is the probability of not having a dog given that there is no cat.
First, find the complement percentages. P(C') = 1 - P(C) = 0.70 and P(D') = 1 - P(D) = 0.67. Then, because P(D'| C') = P(D') (as having a dog does not depend on whether or not you have a cat), the formula simplifies to: P(C' | D') = P(C'). So the probability that a household does not have a cat, given that it doesn't have a dog is 0.70 or 70%.

The number n of aluminum cans used each year is directly proportional to the number of people using the cans. if 250 people use 60,000 cans in one year, how many cans are used each year in dallas, which has a population of 1,008,000.
Answers
________________________________________________________
Explanation:
_______________________________________________________
(60,000) / (250) = "n" / (1,008,000) ;
Solve for "n" ; {number of cans used each year in Dallas} ;
(250) n = (60,000)(1,008,000) ;
Divide each side of the equation by "250" ;
to isolate "n" on one side of the equation; & to solve for "n" ;
→ { (250) n} / 250 = [ (60,000)(1,008,000) ] / 250 ;
to get:
→ n = (60,480,000,000) / (250) ;
→ n = 241,920,000
________________________________________________________
The answer is: " 241,920,000 cans " .
