The probability of spinning an odd number first then spinning an even number is 3/8 x 4/8 = 12/64.

This can be expressed as a fraction, decimal, or percentage. As a fraction, this probability is 12/64. As a decimal, this probability is 0.1875. As a percentage, this probability is 18.75%.

To calculate this probability, we first need to calculate the probability of spinning an odd number first. Since there are eight sections and four of them are odd numbers (1, 3, 5, 7), the probability of spinning an odd number is 4/8. We then need to calculate the probability of spinning an even number. Since there are four even numbers (2, 4, 6, 8), the probability of spinning an even number is 4/8. Finally, we multiply these two probabilities together to get the probability of spinning an odd number first then spinning an even number, which is 3/8 x 4/8 = 12/64.

The inverse function takes the output of the original function and gives the input that would produce that output.

In mathematics, the inverse function (f^-1) of a function f(x) is a function that "undoes" the action of the original function. The relationship between a function f(x) and its inverse function f^-1(y) is such that if f(x) = y, then f^-1(y) = x. In other words, the inverse function takes the output of the original function and gives the input that would produce that output.

It's important to note that not all functions have inverse functions, a function may not have an inverse if it's not one-to-one function, that is, if it's output has more than one input that produces it.

According to the given information in the question rounded to the nearest hundredth, the probability is 0.14.

Probability is a measure of how likely something is to occur. The probability is computed by dividing the total possible outcomes by the number of possible ways the event could occur.

Adding the probabilities together will yield the chance of a simple event occurring. Your total chances of acquiring something are 10% + 25% = 35%, for instance, if you have an 10% opportunity to win $10 and a 25 percentage chance of getting $20.

The probability of a student studied for exactly 5 hours can be calculated using the formula for probability of a discrete event:

P(X = 5) = (number of ways to get a 5) / (total number of outcomes)

From the data provided, we know that 5 students studied for 5 hours. And there were a total of 35 students surveyed. So the probability is:

P(X = 5) = 5/35 = 0.14

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

The overall balance after 2 years on the account after taxes have been paid is 40.00.

The formula for simple interest is:

I=P*T*R

where P is the principal amount of money, R is the interest rate as a decimal, and T is the time.

We know the principal amount is 2000, the interest rate is 5%, and the time is 2 years.

We must convert the interest rate to a decimal.

Divide by 100 or move the decimal place to two spots to the left.

6/100=0.05 or 5.0 --> 0.5 --> 0.05

Now we know all the values.

P=2000

T=2

R=0.05

Substitute the values into the simple interest formula.

I=2000*2*0.05

Multiply.

I=2000*0.1

I=200

The simple interest is 200.00

Now, every year must also pay 20% income tax on the interest earned annually, for that we have to subtract 20% in simple interest.

The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the. sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

Given this, we must first determine what is the position of 49 in Liam's pattern. Since Liam's pattern starts at 7 and increases by 7 each time, we can say that

d = 7

a₁ = 7

Substituting these values, we will get

49 = 7 + (n - 1) * 7

49 = 7 + 7n - 7

49 = 7n

d = 4

a₁ = 4 n = 7

Substituting these values, we will get

a₇= 4 + (7 - 1) * 4

a₇ = 4 + (6) * 4
