Step-by-step explanation:

The mean absolute value of sets 2, 1, 2, 3, and 4 is 12/5.

The mean absolute value of sets 4, 7, and 5 is 16/3.

The mean absolute value is a measure of central tendency that is calculated by finding the average of the absolute values of a set of numbers. It is a way to quantify how spread out a set of numbers is from the mean.

To find the mean absolute value of a set of numbers, we need to first find the absolute values of each number, and then take the average of those absolute values.

For the set of numbers 2, 1, 2, 3, and 4, the absolute values are:

|2| = 2

|1| = 1

|2| = 2

|3| = 3

|4| = 4

Taking the average of these absolute values, we get:

(2 + 1 + 2 + 3 + 4) / 5 = 12 / 5

So the mean absolute value of the set 2, 1, 2, 3, and 4 is 12/5.

For the set of numbers 4, 7, and 5, the absolute values are:

|4| = 4

|7| = 7

|5| = 5

Taking the average of these absolute values, we get:

(4 + 7 + 5) / 3 = 16 / 3

So the mean absolute value of sets 4, 7, and 5 is 16/3.

The predicted total number of calories for a food containing 25 grams of fat is approximately 483.55. 

The equation for the least-squares regression line is:

z = 13.198x + 153.6

where ŷ= predicted value of y (total calories), x = value of the predictor variable (grams of fat), 13.198= slope of the line, and 153.6= y-intercept of the line.

To find the predicted total calories for a food with 25 grams of fat, simplify by substituting x = 25 into the equation.

z = 13.198x + 153.6

ŷ = 13.198(25) + 153.6

ŷ = 329.95 + 153.6

z = 483.55

Therefore, the predicted total number of calories for a food containing 25 grams of fat is approximately 483.55.

According to the investment, after 15 years, the balance in the account would be $1185.

To calculate the final balance after 15 years, we can use the formula for simple interest:

Simple Interest = Principal x Interest Rate x Time

In this case, the principal is $600, the interest rate is 6.5%, and the time is 15 years.

Simple Interest = $600 x 0.065 x 15

Simple Interest = $585

So the investment of $600 earns $585 in simple interest over 15 years. To find the final balance, we add the interest earned to the initial investment:

Final Balance = Principal + Simple Interest

Final Balance = $600 + $585

where t is measured in days, and A(t) represents the amount of flooded land at time t. This function has a B-value of -0.3118.

To model the situation of the flood, we can use an exponential decay function, which represents the decreasing amount of flooded land over time. The function can be written as:

[tex]A(t) = A0 * e^{(-kt)}[/tex]

where A(t) is the amount of flooded land at time t, A0 is the initial amount of flooded land, k is a constant representing the rate of decay, and e is the mathematical constant approximately equal to 2.718.

To determine the value of k, we can use the given information that after 2 days, only 3375 acres of land were under water. Substituting t = 2 and A(t) = 3375 into the equation above, we get:

[tex]3375 = A0 * e^{(-2k)[/tex]

We also know that initially, there were 6000 acres of land under water. Substituting A0 = 6000 into the equation above, we get:

Dividing both sides by 6000, we get:

ln(0.5625) = -2k[tex]ln(0.5625) = -2k[/tex]

Taking the natural logarithm of both sides, we get:

[tex]ln(0.5625) = -2k[/tex]

Solving for k, we get:

[tex]k = -ln(0.5625)/2[/tex]

k ≈ 0.3118

The exponential function that represents the number of new participants as a function of the day number is:

f(x) = 12 * 4ˣ

What is the exponential function?

An exponential function is a mathematical function of the form:

f(x) = aˣ

where "a" is a constant called the base, and "x" is a variable. Exponential functions can be defined for any base "a", but the most common base is the mathematical constant "e" (approximately 2.71828), known as the natural exponential function.

Let's assume that each person who receives a selfie and accepts the challenge sends selfies to 4 new friends the next day.

Then, the number of new participants on Day 1 will be the number of friends that Aliyah, Kim, and Reese each sent selfies to, which is 4 friends each, or a total of 12 new participants.

On Day 2, the 12 new participants each send selfies to 4 new friends, resulting in 4*12 = 48 new participants.

On Day 3, the 48 new participants each send selfies to 4 new friends, resulting in 4*48 = 192 new participants.

We can see that the number of new participants is growing exponentially, with each new day resulting in a larger number of new participants than the previous day.

To write an exponential function that represents the number of new participants as a function of the day number, we can use the general form of an exponential function:

f(x) = a * bˣ

where a is the initial value (the number of new participants on Day 1), b is the growth factor (the factor by which the number of new participants increases each day), and x is the day number.

In this case, we know that a = 12 (the initial number of new participants) and b = 4 (the factor by which the number of new participants increases each day, since each participant sends selfies to 4 new friends).

Therefore, the exponential function that represents the number of new participants as a function of the day number is:

Step-by-step explanation:

The chance that the number of heads will be in the range 4850 to 5150 is approximately 0.9973, or about 99.73%.

The number of heads in 10,000 coin tosses follows a binomial distribution with parameters n = 10,000 (the number of trials) and p = 0.5 (the probability of heads on a single toss).

We can approximate this binomial distribution using the normal distribution, with mean μ = np = 5000 and variance σ² = np(1-p) = 2500.

To find the probability that the number of heads is in the range 4850 to 5150, we can use the normal distribution and standardize the range using the z-score formula:

z = (x - μ) / σ

where x is the number of heads in the range we're interested in.

For the lower bound of 4850, we have:

[tex]z_lower = (4850 - 5000) / \sqrt{(2500)}[/tex]

= -3

For the upper bound of 5150, we have:

[tex]z_upper = (5150 - 5000) / \sqrt{(2500)} = 3[/tex]

Using a standard normal distribution table or calculator, we can find the probability of being within 3 standard deviations of the mean:

P([tex]z_lower[/tex]  < Z < [tex]z_upper[/tex] ) ≈ P(-3 < Z < 3)

= 0.9973.
