Considering the definition of an inequality, the number of days Sebastian can afford to rent while staying within his budget is less than or equal to 6.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

In this case, you know that:

Being "d" the number of days Sebastian can afford to rent while staying within his budget, the inequality that expresses the previous relationship is

40.50×d - 400×0.12 ≤ 210

Solving:

40.50×d - 48 ≤ 210

40.50×d ≤ 210 + 48

40.50×d ≤ 258

d ≤ 258÷ 40.50

d ≤ 6.37

Finally, the number of days Sebastian can afford to rent while staying within his budget is less than or equal to 6.

y = x - 4 is an equation of the line in slope-intercept form passing through points (4 , 0) and (-3 , -7)

An equation of a line in slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept.

Given two points passed through by the line, you can use them to write the equation of the line in slope-intercept form.

1. Find the slope of the line using the two given points.

let Point 1(4 , 0) and Point 2(-3 , -7)

slope = m = (y2 - y1) / (x2 -x1)

m = (-7 - 0) / (-3 - 4)

m = -7/-7

m = 1

2. Use the value of the slope and one of the points to find the value of the y-intercept, b. Plug in these values in the formula for slope-intercept form.

y = mx+ b

y = 1x + b

Using Point 1,

0 = 1(4) + b

b = -4

3. Write the equation of the line in slope-intercept form.

y = mx+ b

where m = 1 and b = -4

y = x - 4

The require answers are,

Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350

Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x

Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of the digital images and the permission = $125

“one time” charges = $3.25

Part a: The equation for the total cost of the calendars

THere are 100 calendars printed.

So, “one time” charge = 3.25*100

So, the total cost of the calendars C is given as,

C = 125 + 3.25*100

C = 125 + 325 = 450

Thus, the equation for the total cost of the calendars is given as,

C = 125 + 3.25*100 = 450

Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed

Let there are x calendars printed

Total “one time” charges = 3.25x

So, Average cost is given as,

A = 125 + 3.25x

this is the model that gives the average cost A per calendar

Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar

Now from the graph it must be seen that the average cost drops to $ 5 per calender at 70.

Thus, number of calendars that must be sold before the average cost drops to $5 per calendar = 70

Thus, the require answers are,

Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350

Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x

Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.

At present, the age of the woman is 29 years, while the age of her daughter is 6 years.

In the question, we are given two characters, a woman and her daughter, and told to find their present age. We are also given some clues as to how we will arrive at the answer. Let's consider the first one.

In the first sentence, we are told that 5 years ago, the woman was 4 times as old as her daughter. We don't know the woman's age or her daughter's, so let's call the woman's present age x and her daughter's present age y for now. To know the age of the woman 5 years ago, we will subtract 5 from her current age, which will give us x - 5. Also, the woman was 4 times as old as her daughter 5 years ago, hence:

                                    x - 5 = 4y

If we rearrange that;      x = 4y + 5 (let's call this equation 1)

Now, on to the second clue.

In the second sentence, we are told that in four years time, the woman will be two and a half times as old as her daughter. The woman's age in 4 years time is x + 4, hence:

                                 x + 4 = 2[tex]\frac{1}{2}[/tex]y

                                 x + 4 = 5y/2

                                 2x + 8 = 5y (let's call this equation 2)

Next, we will find the value of y (the daughter's present age) by substituting equation 1 into equation 2, that is, putting '4y + 5' in place of x in equation 2, thus:

                            2(4y + 5) + 8 = 5y

                            8y + 10 + 8 = 5y

                            8y - 5y = 18

                             3y = 18

                              y = 6

Therefore, at present, the daughter is 6 years old. To find the mother's age, we will substitute the daughter's age in place of y in equation 1:

                        x = 4y + 5

                        x = 4(6) + 5 = 29

Hence, the woman is 29 years old, and her daughter is 6 years old.

Substitution method of solving a system of equations replaces the variable with a value while elimination method of solving a system of equations removes the variable from the equations.

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

example:

Given two equations: x + 3y = 7 and 2x - 4y = 24, find the solution.

Using substitution method, express one equation to an equation of one of its variables(in terms of the other variable).

x + 3y = 7   ⇒   x = 7 - 3y

Substitute it to the other equation and solve for y.

2x - 4y = 24

2(7 - 3y) - 4y = 24

14 - 6y - 4y = 24

-10y = 10

y = -1

Substitute the value of y in any of the equations and solve for x.

x = 7 - 3y

x = 7 - 3(-1)

x = 7 + 3

x = 10

Hence, the solution is (10 , -1).

Using elimination method, multiply the first equation by 2 so that if we add or subtract it to the second equation, a variable will be removed.

x + 3y = 7   ⇒   2x + 6y = 14

Subtracting equation 2 from equation 1,

2x + 6y = 14

2x - 4y = 24

0x + 10y = -10

y = -1

Substitute the value of y in any of the equations and solve for x.

x + 3y = 7

x + 3(-1) = 7

x = 7 + 3

x = 10

Hence, the solution is (10 , -1).

In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p. The probability of observing x successes in N trials is calculated using the binomial distribution, with p standing for the probability of success on a single trial. According to the binomial distribution, p is fixed throughout all trials.

The probability of success raised to the power of the number of successes and the probability of failure raised to the power of the difference between the number of successes and the number of trials are multiplied to create the binomial distribution. In mathematics and statistics, the binomial distribution is the likelihood that a specific outcome in a series will occur when there are only two possible outcomes: success or failure. Bi is the prefix for two.

Use the formula for the mean for the Binomial Distribution: μ = np

• n = 16

• p = ½

Therefore μ = 16 × ½ = 8

The mean number of heads is 8.
