Let f(t) be the population (in thousands of people) of Math City, as a function the time t (in years), where t = 0 corresponds to the year 2020. In 2020, the population was 34000, and each year the population increases by 3000 people.
(a) Model the population by finding a formula for f(t), using the appropriate choice of a linear, polynomial, power, trigonometric, or exponential function, or a piecewise combination thereof.
(b) Evaluate the expression f(6), and write a sentence explaining what this means.
(c) Solve the equation f(t) = 64, and write a sentence explaining what this means

Answers

The f(t) formula is f(t) = 34 + 3t. The expression f(6) = 52; this means that in 2026, the population was 52000 people, and Setting 34 + 3t = 64 leads to t = 10, which means in 2030, the population was 64000 people.

(a) Each year, the population increases by 3000 people; this means that the population is a linear function of time, and its slope is 3 thousand people per year. The population in 2020 was 34000, and so (0, 34) is the vertical intercept, and we have

f (t) = 34 + 3t.

(b) f(6) = 34 + 3×6

f(6) = 34 + 18

f(6) = 52

This means in 2026, the population was 52000 people.

(c) f(t) = 64

34 + 3t = 64

3t = 64 - 34

3t = 30

t = 10

This means in 2030, the population was 64000 people.

a) What is the probability that the person selected will be someone whose response is Sports and who is a woman?

b) What is the probability that the person selected will be someone whose response is TV or who is a man?

c) What is the probability that the person selected will be someone whose response is Sports given that the person is a man?
d) For the people surveyed, are the events of being a person whose response is Sports and being a man independent? Justify your answer.

d) For the people surveyed, are the events of being a person whose response is Sports and being a man independent? Justify your answer.

e) Assume that, in a large population, the probability that a person will respond watching TV is
0.32. If 6 people are selected at random from the population, what is the probability that at least 4 of the people selected will respond watching TV as their favorite activity? Support your answer.

Answers

a) The probability of this event is 0.08., b) The probability is 0.3 + 0.6 - 0.06 = 0.84, c) P(Sports | Man) = 0.12 / 0.6 = 0.2

d) For the people surveyed, the events of being a person whose response is Sports and being a man are not independent.

e) The probability that at least 4 of the people selected will respond watching TV as their favorite activity is 1 - 0.2097 = 0.7903

What is the likelihood of the terms given?

a) We need to multiply the proportion frequency of women responding with Sports (0.2) by the relative frequency of women to get the likelihood that the individual chosen will be a woman (0.4).

Thus, we obtain: 0.2 * 0.4 = 0.08 Therefore, the likelihood of this occurring is 0.08.

b) We can add the relative frequency of TV for men (0.3) and the relative frequency of men (0.6) and subtract the overlap (the relative frequency of TV for men and men), which is equal to 0.2 * 0.3 = 0.06 to determine the likelihood that the individual chosen would either respond with TV or be a man.

The probability is therefore 0.3 + 0.6 - 0.06 = 0.84

c) Using the algorithm, we can determine the likelihood that the individual chosen will be a guy and that their response to the question will be "Sports." P(Sports and Man) = 0.2 * 0.6 = 0.12 P(A and B) = P(A and B) / P(B) P(Sports and Man) = P(Sports and Man) / P(Man)

P(Sports|Man) = 0.12/0.6=0.2

d) For the respondents, being a man and having selected "Sports" as a response are not separate events. P(Sports and Man) = 0.12 and P(Sports) * P(Man) = 0.2 * 0.6 = 0.12, which are not equivalent, demonstrate this.

e) Using binomial distribution, the probability that at least 4 of the people selected will respond watching TV as their favorite activity is 1 -

P(X < 4) - P(X = 4)

P(X < 4) = (6 C 0) * (0.32)^4 * (0.68)^2

P(X = 4) = (6 C 4) * (0.32)^4 * (0.68)^2

P(X < 4) + P(X = 4) = 0.2097

Therefore the probability that at least 4 of the people selected will respond watching TV as their favorite activity is 1 - 0.2097 = 0.7903

Compare the investment below to an investment of the same principal at the same rate compounded annually.
principal: $9,000, annual interest: 4%, interest periods: 2, number of years: 15

Answers

Answer:

Step-by-step explanation:

The investment below is compounded semi-annually, while an investment of the same principal at the same rate compounded annually would have interest compounded once per year.

The formula for compound interest is A = P(1 + r/n)^nt where A is the final amount, P is the principal, r is the annual interest rate, n is the number of times the interest is compounded per year and t is the number of years.

In the case of the semi-annual investment:

A = 9000(1 + 0.04/2)^(2*15) = $21,831.62

In the case of the annual investment:

A = 9000(1 + 0.04)^15 = $21,812.30

As we can see, the semi-annual investment yields a slightly larger return than the annual investment, $19.32 more. Compounding interest more frequently results in a larger return due to the interest earning interest.

So, only option C is a counterexample of the conditional statement "If a number is divisible by 4, then it is divisible by 8."

A counterexample of a conditional statement is a specific case or example that contradicts the statement or goes against its logical implications.

In this case, the conditional statement is "If a number is divisible by 4, then it is divisible by 8."

Option C, 36, is a counterexample of this conditional statement.

This is because 36 is divisible by 4 (9 x 4 = 36), but it is not divisible by 8 (36 / 8 = 4.5). This contradicts the statement that if a number is divisible by 4, it must also be divisible by 8.

Option A, 12, is not a counterexample of the conditional statement because 12 is divisible by 4 (12 / 4 = 3) and also divisible by 8 (12 / 8 = 1.5).

Option B, 32, is not a counterexample of the conditional statement because 32 is divisible by 4 (32 / 4 = 8) and also divisible by 8 (32 / 8 = 4).

Answers

Through the given data points the domain of the function is 1 ≤ n ≤ 5.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The domain of a function is the complete set of all possible values of independent variable.

The points associated with the graph is (1,15) and (5,11).

The formula for equation is (y - y1) =  (y2-y1)/(x2-x1) (x - x1).

(y2-y1)/(x2-x1) = (11 - 15)/(5 - 1)

m = -4/4

m = -1

Now, the equation can be written as -

y - y1 = m(x - x1)

y - 15 = -1(x - 1)

y - 15 = -x + 1

y = -x + 16

From the graph k = -n + 16

The independent variable 'n', taking the values between 1 and 5, in that interval graph is continuous.

Therefore, the domain is 1 ≤ n ≤ 5.

The range is the difference between the highest and lowest values in the data set, in this case, 98 - 1 = 97.

We can divide the range by the number of classes to determine the class interval. In this case, 97/5 = 19.4.

We will round up to 20 to have easily divisible numbers.

The class intervals with the frequency would be:

1-20: 3

21-40: 2

41-60: 0

61-80: 3

81-100: 2

Next, we need to create a frequency histogram by plotting the class intervals on the x-axis and the frequencies on the y-axis, and then drawing a bar for each class interval representing the frequency.

The histogram will be skewed right. A histogram is skewed right when the tail of the histogram extends farther to the right than the left. In this case, the majority of the data falls in the lower class intervals, but there are a few outliers on the higher end, which extends the histogram to the right.

Given the system of equations: 5x + 2y = 3 4x − 8y = 12 Solve for (x, y) using elimination.

Answers

To solve the system of equations using elimination, we can follow these steps:

Multiply the first equation by 4, and the second equation by 2:

20x + 8y = 12

8x - 16y = 24

Add the two equations together:

20x + 8y = 12

8x - 16y = 24

28x - 8y = 36

Solve for x by dividing both sides of the equation by 28:

x = 36/28 = 9/7

Substitute the value of x back into one of the original equations:

5x + 2y = 3

5(9/7) + 2y = 3

45/7 + 2y = 3

2y = -42/7

Solve for y by dividing both sides by 2:

y = -21/7

So the solution of the system of equations is (x,y) = (9/7, -21/7)

It is also worth noting that we could have also multiplied the first equation by -2 and the second equation by 5 and added them together, this will also lead us to the same solution.

Mike earns 5.00 per hour overtime is paid at the time and half of his regular rate worked 42 hours last week what is mikes gross pay

Answers

The gross pay mike for last week is $210.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given, Mike earns 5.00 per hour overtime is paid at the time and half of his regular rate worked 42 hours last week.

Since it is not mentioned that mike worked overtime or not so we will consider this a normal work hour for a week is 42 hours.

Thus total he earns = 42*5

total he earns = 210$

If he works overtime,

for every hour he worked overtime he would get = 1.5* 5

for every hour he worked overtime he would get = 7.5

Therefore, For the week mike's gross pay is $210.

1. A manufacturer drills a hole through the center of a metal sphere of radius R. The hole has a radius r. Find the volume of the resulting ring.

2. Use the shell method to write and evaluate the definite integral that represents the volume of the solid generated by revolving the plane region about the x-axis.
[tex]y=\frac{1}{x}[/tex]

Answers

The volume of the metal sphere is 4π/3(R^3 - r^3)

The volume of the solid generated is 2π cubic units.

The volume of the metal sphere

The volume of the ring can be found by subtracting the volumes of two spheres with radii R and r:

V = (4/3) * π * (R^3 - r^3)

So, the volume of the ring is given by:

V = (4/3) * π * (R^3 - r^3) cubic units.

Evaluate

V = 4π/3(R^3 - r^3)

The volume of the solid generated

We have the equation to be

y = 1/x

The volume of the solid is given by the definite integral:

V = 2π ∫[a,b] x * y dx

where a and b are the lower and upper limits of the interval over which we are integrating.

In this case, a = 1 and b = 2, so the volume of the solid is given by:

V = 2π ∫[1,2] x * 1/x dx = 2π ∫[1,2] dx = 2π (x)|[1,2] = 2π (2 - 1) = 2π.

So, the volume is to 2π cubic units.
