How to solve: 24 - (5 + 3)^2 + 4 × 2^3 step by step.

Answer:

the number greater than 5 is only 6 in the case of a coin.

Step-by-step explanation:

in a coin numbers greater than 5 is only 6

probability= No of required outcome/ No of possible outcome.

P.B= 1/6

in a coin there is head or tail

P.B of getting tail

P.B= Tail/Head + Tail

P.B= 1/2

The coin of course, has two sides, heads and tails. Assume we are talking about a six-sided die. Let's look at the individual probabilities.

There are only two sides to the coin, tails being one of them, so:
p(tails) = 1/2

The die goes from 1 to 6. We need to see the numbers that fit the inequality:

p(5 < x ≤ 6)
There is only one integer that is greater than five and less than or equal to six, and that is six. If there is only one number out of six, then:
p(>5) = 1/6

When dealing with probabilities, to determine the probability of two things happening, multiply both probabilities.

1/2 x 1/6 = 1/12

It is a function because the mapping .

(A) Due to the fact that there are no two values in Set B that have only one value in Set A mapped to them, the mapping diagram above represents a function.

(B) A function's very special property is that it associates one output with each input.

(C) Set A represents the domain, whereas Set B represents the range. Therefore, there would be exactly one value in the range that was unique for each value in the domain and would be present for each value in the domain.

In mathematics, a function from a set X to a set Y assigns each element of X exactly one element of Y. The subsets X and Y are referenced to as the function's domain and codomain, correspondingly. A function is described as a relationship between a group of inputs with one output each. A function is, to describe it simply, a connection between inputs in which each input is associated to exactly one output. Every function has a domain and a codomain, or range. A function is a type of rule that produces one output from one input. Y=X2 is a good illustration of this. Any input for x yields a single output for y.

The graph which represents the polynomial function f(x) = x^3 - 2x^2 - 5x + 6 is in option A.

First, let us understand the polynomial function:

A polynomial function is one that uses only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on. For example, 9y + 6 is a polynomial with an exponent of 1.

We are given:

f(x) = x^3 - 2x^2 - 5x + 6

We know that, when the graph intersects the x-axis, it satisfies the equation that is f(x) = 0 at that point.

Let us check the points one by one;

Option A;

The graph intersects the x-axis at -2, 1, and 3 it should satisfy the equation f(x) = 0.

Let's put x = -2 in f(x), we will get;

f(-2) = -2^3 - 2(-2)^2 - 5(-2) + 6 = -8 - 8 + 10 + 6 = -16 + 16 = 0

f(-2) = 0.

Let's put x = 1 in f(x), we will get;

f(1) = 1^3 - 2(1)^2 - 5(1) + 6 = 1 - 2 - 5 + 6 = 7 - 7 = 0

f(1) = 0.

Let's put x = 3 in f(x), we will get;

f(3) = 3^3 - 2(3)^2 - 5(3) + 6 = 27 - 18 - 15 + 6 = 33 - 33 = 0

f(3) = 0.

So, the points -2, 1, and 3 satisfy the equation f(x).

Thus, the graph which represents the polynomial function f(x) = x^3 - 2x^2 - 5x + 6 is in option A.

Answer: The quotient is 3y² + 2y - 1.

Step-by-step explanation:

You can use long division to solve this expression by setting the dividend under the roof and the divisor outside as you would normally do when dividing numbers.

1) Look at the first term of the dividend, 15y³, and the first term of the divisor, 5y. Determine what value multiplied by 5y would give you 15y³. The answer is 3y², and given the number, you multiply it by the WHOLE divisor.

3y²(5y + 6) = 15y³ + 18y² <-- subtract this from the dividend.

2) Continue this process and make sure to drag down the next term for each new value you form after subtracting. Keep in mind of any negative values! When you reach up to -5y, determine what value multiplied by 5y would give you the value of -5y, which would be -1.

3) You should be left with a remainder of 0, leaving you with a quotient of 3y² + 2y - 1.

Answer:

See below.

Step-by-step explanation:

Each of the graphs shows a line segment, but because of the arrowheads, each situation is different.

Left graph.

The line segment has a point at each end. The graph is of just the line segment shown.

The lowest x-coordinate is -4.

The greatest x-coordinate is 3.

The lowest y-coordinate is 2.

The greatest y-coordinate is 5.

Domain: -4 ≤ x ≤ 3

Range: 2 ≤ x ≤ 5

In interval notation:

Domain: [-4, 3]

Range: [2, 5]

Middle graph.

The line segment has a point at the right endpoint but an arrowhead at the left. The graph is a ray that starts at point (2, 2), goes through point (-4, 5) and keeps going forever past point (-4, 5) in the direction of the segment.

The lowest x-coordinate is -∞.

The greatest x-coordinate is 2.

The lowest y-coordinate is 2.

The greatest y-coordinate is ∞.

Domain: x ≤ 2

Range: x ≥ 2

In interval notation:

Domain: (-∞, 2]

Range: [2, ∞)

Right graph.

The line segment has an arrowhead at each end. The graph is a line that includes the line segment shown. A line has no beginning and no end; therefore, it goes on in both directions forever.

The lowest x-coordinate is -∞.

The greatest x-coordinate is ∞.

The lowest y-coordinate is -∞.

The greatest y-coordinate is ∞.

Domain: all real numbers

Range: all real numbers

In interval notation:

Domain: (-∞, ∞)

Range: (-∞, ∞)

Answer:

1.  Domain: [-4, 3]    Range: [2, 5]

2.  Domain: (∞, 2]    Range: [2, ∞)

3.  Domain: (-∞, ∞)    Range: (-∞, ∞)

Step-by-step explanation:

Domain: The set of all possible input values (x-values).

Range: The set of all possible output values (y-values).

An open circle indicates the value is not included in the interval.

A closed circle indicates the value is included in the interval.

An arrow shows that the function continues indefinitely in that direction.

Note:  Assume that each square on the given graphs is 1 unit.

Question 1

There are closed circles at both endpoints of the line: (-4, 2) and (3, 5).

Therefore, the values are the endpoints of the intervals.

Question 2

There is a closed circle at (2, 2).

There is an arrow at one endpoint, so as x → -∞, y → ∞.

Question 3

There are arrows at the endpoints of the line.

Therefore, the domain and range are unrestricted.

In the given question we have to find the value of u.

The given expression is -1/2u+3/5=1/6

Simplifying the given expression to find the value of u.

-1/2u+3/5=1/6

Subtract 3/5 on both side, we get

-1/2u=1/6-3/5

Now equal the denominator to simplify

-1/2u=1/6 *30-3/5 *30

-1/2 *30u=5-3*6

-15u=5-18

-15u= -13

Cost of goods sold       $332          $191                $268.60

FIFO (First-in, First-out) is based on the assumption that the physical flow of goods sold depends on the chronological order of acquisition.

LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.

The weighted-average method uses the average cost of goods to determine both the ending inventory and the cost of goods sold.

LIFO:

Ending inventory = $704 ($48 + $264 + 28 x $14)

Cost of goods sold = $332 ($1,036 - $704)

FIFO:

Ending inventory = $845 (11 x $11 + 30 x $14 + 19 x $16)

Cost of goods sold = $191 ($1,036 - $845)
