Changing [f(-1) = 1] into coordinate points, we get (x₁, y₁) = (-1, 1),

Changing [f(2) = 7] into coordinate points, we get (x₂, y₂) = (2, 7),

Also, changing [f(1) = 1] into coordinate points, we get (x₃, y₃) = (1, 1),

And finally, changing [f(3) = 0] into coordinate points,

We get (x₄, y₄) = (3, 0).

As per question statement, we are provided with Four separate functions, as follows, [f(-1) = 1], [f(2) = 7], [f(1) = 1] and [f(3) = 0].

We are required to convert the above mentioned functions into coordinate points.

To solve this question, we need to know the standard form of conversion of functions into coordinate points, which goes as [y = f(x)], i.e., the ordinate is a function of the abscissa.

Thus comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1).

Similarly, comparing [y = f(x)] to [7 = f(2)], we get (x, y) = (2, 7),

Comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1),

And finally, comparing [y = f(x)] to [0 = f(3)], we get (x, y) = (3, 0).

Step-by-step explanation:

The truth value of the conditional statement is false, and the counterexample of this statement is corresponding angles

The conditional statement is given as:

If two angles are congruent, then they are vertical angles.

The above statement is false because not all congruent angles are vertical angles

A counterexample of this statement is a corresponding angle

i.e. corresponding angles are congruent angles, but they are not vertical angles

Hence, the truth value of the conditional statement is false, and the counterexample of this statement is a corresponding angle

Answer:

Algebraic Expressions- An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc. For example, let us have a look at the expression 2x + 4. Thus, we can say that 2x + 4 is an example of an algebraic expression.

Here are more examples:

• 5x + 4y + 10

• 2x2y - 3xy2

• (-a + 4b)2 + 6ab

To simplify an algebraic expression, we just combine the like terms. Hence, the like variables will be combined together. Now, out of the like variables, the same powers will be combined together

Multiply the numbers

   x - 3 . 5x – 3x -12 - 4x + 18x - 7

= x – 15x - 3x – 12 – 4x + 18x – 7  

  Subtract the numbers

= x – 15x – 3x – 12 – 4x + 18x - 7

= x – 15x – 3x – 19 - 4x + 18x

  Combining the like terms

= - 2x – 19

The inequality to represent the temperatures at which the propane is safe to use is -40 < x < 120.

It is said that it is safe to use Propane between the temperatures of -40°C and 120°C.

We already know the use of an equality. It makes the values on both sides of it equivalent.

An inequality compares the values on both sides of it. It informs us which one is greater than or less than the other or if they are equal. That is, inequality has a possibility for equality too.

Here the minimum temperature at which propane is safe to use = -40°C

The maximum temperature at which Propane is safe to use = 120°C

We take a variable 'x' to denote the safe temperature of Propane.

Then according to the information, the inequality to represent the temperatures at which the propane is safe to use is,

            -40 < x < 120

An inequality is written with the bigger value is in the open end of '<' and the lower value at the other end.

The probability of a given event gives a result of 0.00037. It is generated by applying the basic concepts of probability to the assigned problem.

What is probability?

Probability depicts the number of possibilities of how many times an event can occur. The probability of happening of an event invariably lies between 0 and 1. For a sure event, it is always 1. Its formula is given as P(E) = No. of favourable outcomes / Total no. of outcomes

Calculation of finding the probability according to the conditions specified

The entire number of cards in a standard deck = 52

Total number of favourable outcomes = 1

The probability of selecting two cards is given by P(E1) which is equal to 1 / 52

P(E1) = 1 / 52

Another card is selected without replacing the first card, so the total number of cards in the deck becomes 51. The probability of selecting a card from these 51 cards is given by P(E) i.e. (1 / 52) × (1 / 51)

P(E) = 1 / 2652

P(E) = 0.00037

Hence, the required probability is given by 0.00037.

We get that the total dipers that Charlie's mom will use in the month of June and July will be 549 dipers.

Charlie's mom uses an average of 9 diapers a day.

Average = 9

Average means a number that is calculated by adding quantities together and dividing the total by the number of quantities.

Average = Sum of observations / number of observations

A = S / N

We know that:

June has = 30 days

July has = 31 days.

Total days = 30 days + 31 days = 61 days

N = 61

Let the sum = S be x.

Substituting the values in the formula, we get that:

9 = S / 61

S = 9 × 61

S = 549

Therefore, we get that the total dipers that Charlie's mom will use in the month of June and July will be 549 dipers.

Answer:

The length of the rectangle is 11 inches, and the width of the rectangle is 10 inches.

Step-by-step explanation:

Let l be the length of the longer side of the rectangle. Then the width of the rectangle is l-1 inches. Since the perimeter of the rectangle is 42 inches, we have:

2(l + l - 1) = 42

l + l - 1 = 21

2l = 22

l = 11 inches, so l - 1 = 10 inches

The mean absolute deviation of this data set is 0.2

The dataset is given as

0.7, 1.4, 3 and 2

Calculate the mean using

m(x) = Sum/Count

So, we have

m(x) = (0.7 + 1.4 + 3 + 2)/4

Evaluate

m(x) = 1.775

The mean absolute deviation is calculated as

Deviation = 1/n∑|(x - m(x))|

So, we have

Deviation = 1/4 * (|0.7 - 1.775| + |1.4 - 1.775| + |3 - 1.775| + |2 - 1.775|)

This gives

Deviation = 1/4 * (-1.075 + 0.375 + 1.225 + 0.225)

Evaluate

Deviation = 0.1875

Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

Answer:

39.

Step-by-step explanation:

I say good try to the first guy, but aye, it's not fully answering the question.

PEMDAS is the order you solve all of this in. Parenthesis (), Exponents (^), Multiplication (*), Division (/), Addition (+), and Subtraction (-).

We would solve (8-5) first for 3, since there is no sign between both three's, this will be multiplication.

Next is the exponent, 11^2 is 11*11, which is equal to 121.

121 - 3 * 3 * 7 - 19

Next up is Multiplication. 3 * 3 = 9, and 9 * 7 is 63.

Now our equation is 121 - 63 - 19. There is no Division or addition symbol, so we skip to Subtraction.

121 - 63 = 58, and 58 - 19 = 39.

Your Answer is 39.

Considering the definition of volume and volume of a cube, the edge length of the fish tank is 6 inches.

All matter occupies a space that can vary depending on its size. This space can be defined by volume, which is defined as the extension of an object in its three dimensions. That is, the volume corresponds to the measure of the space that a body occupies.

The cube is a polyhedron or three-dimensional geometric figure, with six equal sides, each of which is a regular polygon, that is, a square. In other words, a cube is a body made up of six faces that are square.

The volume of a cube is equal to the measure of its side to the cube:

Volume = side x side x side = side³

In this case, you know that:

Replacing in the definition of volume of a cube:

216 cubic inches = side³

Solving:

∛216 cubic inches= side

6 inches= side

Finally, the edge length of the fish tank is 6 inches.
