Domain of {(0, −2), (-3, 1), (-4, 3), (1, −4)} is (0, -3, -4, 1) and range of

{(0, −2), (-3, 1), (-4, 3), (1, −4)} is (-2, 1, 3, -4).

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values. In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).

Given,

{(0, −2), (-3, 1), (-4, 3), (1, −4)}

The set of all x coordinates makes up the domain, while the set of all y coordinates makes up the range.

Domain = (0, -3, -4, 1)

Range = (-2, 1, 3, -4)

Domain of {(0, −2), (-3, 1), (-4, 3), (1, −4)} is (0, -3, -4, 1) and range of

a. The shape of the distribution is normal, by the Central Limit Theorem.

b. The mean is of: 0.23.

c. The standard error is of: 0.125, meaning that the sample proportions differ by around 0.125 from the mean of 0.23.

d. The probability is of: 0.2877 = 28.77%.

By the Central Limit Theorem, as each sample has at least 10 successes and at least 10 failures, the shape of the distribution is normal.

For each sample, the mean and the standard error are given as follows:

Hence for the distribution of differences, the mean and the standard error are given as follows:

Using the z-score formula, the probability that the difference is greater than 30 is one subtracted by the p-value of Z when X = 0.3, hence:

Z = (0.3 - 0.23)/0.125

Z = 0.56

Z = 0.56 has a p-value of 0.7123.

1 - 0.7123 = 0.2877 = 28.77%.

The decrease of the population from the question can be modeled by;

P = 92000e^-0.02t

We know that the population of a place can be modeled by the use of an exponential model. In the exponential model, there could be an increase or  decrease in the population of a place as the case may be. In this case, we are told that there is a decrease in the population of the place.

Let us note from the question that we have been told that every year after 2010, the population decreased by 2% due to heavy population. We were also made to understand in the question that the initial population of the city is about 92000.

Now, we can write the model as;

P = Poe^-rt

P = population of the area at time t

Po = population initially present

r = rate of population decrease

t = time taken since 2010.

We can now write;

P = 92000e^-0.02t

It takes 15 minutes for 1 bracelet. 15 minutes multiplied by 21 bracelets is 315. Lmk if you need more help

Answer: 315 minutes.

Step-by-step explanation:

To solve this, we need to find out how long it takes to make one bracelet first.

If it takes 45 minutes to make 3 bracelets, we need to divide 45 by 3, which gives us 15.

This means it takes 15 minutes to make one bracelet.

Now, we need to multiply 15 by 21.

15 x 21 = 315.

This means it will take 315 minutes to make 21 bracelets.

He would pay $8500 interest if he can afford payments of $425 per month and can borrow the money at an interest rate of 4% compounded monthly for 5 years.

The expense of borrowing money is interest. It equates to a fee or additional charge the borrower pays the lender for the loaned amount, and is sometimes stated as a percentage. When you make a payment on a loan with simple interest, the money first goes toward the interest for that month and the rest is applied to the principal. Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.

Given,

Principal = $425

Rate = 4%

Time = 5 years

Interest = Principal × Rate × time

Interest:

= 425 × 4×5

= 8500

The perimeter of a face of a cube is 60m that has volume 125 m³.

The total number of cubic units that a cube occupies in three dimensions is its volume. Six faces, twelve edges, and eight vertices make up the three-dimensional shape of a cube. Therefore, the area encircled by a cube's six faces is considered to equal its volume. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity. The volume of a cube can be calculated by three times multiplying the edge length.

Given,

Volume of cube = side³

Volume = 125 m³

After 4.6 years the car's worth will be $10,600 or less.

According to the question,

We have the following information:

A car is purchased for $38,000. Each year it loses 20% of its value.

Now, we will first find 20% of 38,000:

(20*38000)/100

$7600

Now, each year the decrease in the price will be $7600.

So, we have the following arithmetic progression:

38000, 30400, ...

Now, following formula is used to find the nth term of an A.P:

an = a+(n-1)d where a is the first term and d is the common difference

10,600 = 38000+(n-1)-7600

10600-38000 = -7600n+7600

-27,400 = -7600n+7600

-7600n = -27400-7600

-7600n = -35000

n = 35000/7600

n = 4.6 years
