a. Roster form: { 3, 4,5, 6}

b. Set-builder form : {x | x is an integer, where x ≥ -5}

What is a Roster form?

A list of the elements of a set, each separated by a comma, enclosed in a group of curly brackets, can be used to describe the contents of the set. Roster form is the term for this method of describing a collection.

What is a set-builder form?

Set builder notation is defining a set by expressing its properties rather than simply listing its constituents. One or more variables and a rule specifying which elements are part of the set and which are not are included in the set builder notation.

Here,

a. It is given the set is A={x:x is an integer 3 ≤ x ≤ 6}.

Then the integers lying between 3 and 6 are 3,4,5,6.

So the roster form is

A={3,4,5,6}.

b. It is given that  A = { -5, -4, -3, -2......}

then the set-builder form is

A = {x | x is an integer, where x≤ -5}

Hence,

a. Roster form: { 3, 4,5, 6}

b. Set-builder form : {x | x is an integer, where x ≥ -5}

Answer:

a.) The relation is linear

b.) Plot the given (x,y) coordinates on the given graph and connect them.

c.) The y-intercept is at y=2.

d.) m=4

e.) y=4x+2

Step-by-step explanation:

a.) The relation is linear because the values in the sequence of first differences are all equal:

6-2=4   10-6=4   14-10=4   18-14=4

c.) The y-intercept is the point on the graph where x=0.  According to the given points, the y-intercept must be y=2.

d.)

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\(x_1,y_1)=(0,2)\\(x_2,y_2)=(4,18)\\m=\frac{18-2}{4-0}\\m=4[/tex]

e.) Plug slope (m) and y-intercept into the slope-intercept form to get y=4x+2.

The equation that best represent the relationship on the scatter plot is y = 6 / 5 x + 18 / 5.

The line of best fit is used to express a relationship in a scatter plot of different data points.

The line of best fit (or trendline) is an educated guess about where a linear equation might fall in a set of data plotted on a scatter plot.

Therefore, the line of best fit will pass through (2, 6)(7, 12) and (12, 18).

Therefore, the equation of the line can be represented as follows;

y = mx + b

where

Therefore,

m = 12 - 6 / 7 - 2

m = 6 / 5

Let's find y-intercept using (2, 6)

6 = 6 / 5(2) + b

6 - 12 / 5 = b

b = 18 / 5

Therefore, the equation is y = 6 / 5 x + 18 / 5

The domain and range are [−4, 1] & [−4, 5].

What are the domain and range of a graph?

Graphs can also be used to determine the domain and range of functions. Because the domain refers to the set of possible input values, the domain of a graph includes all of the input values shown on the x-axis. The range is the set of possible output values shown on the y-axis.

We have given the graph,

The domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis.

The range is the set of possible output values, which are shown on the y-axis.

We can observe that the graph extends horizontally from −4 to the right 1.  so the domain of function h is [−4, 1].

The vertical extent of the graph is 0 to –4, so the range of function h is [−4, 5].

The measures of the angles are m∠1 = 69° and m∠2 = 29°

How to find the measures of an angle?

*Triangles always have angles that add up to 180 degrees. As a result, you may find the unknown angles by taking the specified angles of a triangle and subtracting them from 180.

*Finding Unknown Measurements Using Exterior Angles

Two angles that together total 180 degrees are known as supplementary angles. These two angles combine to form a straight angle when put side by side

m∠1 = (4x-7)°

m∠2 = (x+12)°

As the two angles are complementary

4x-7+x+12=90°

5x+5=90°

5x=90-5

5x=85

x=[tex]\frac{85}{5}[/tex]

x=17

Therefore

m∠1 = 4(17)-7

m∠1 = 61°

m∠2 = 17+12

m∠2= 29°

Part (a)

The term "disjoint" is the same as "mutually exclusive".

If events E and F are disjoint, then we know that P(E and F) = 0. In other words, the two events have nothing in common. Therefore, it's impossible for them both to occur simultaneously.

P(E or F) = P(E) + P(F) - P(E and F)

P(E or F) = 0.4 + 0.5 - 0

P(E or F) = 0.9

====================================================

Part (b)

If events E and F are independent, then P(E and F) = P(E)*P(F).

P(E or F) = P(E) + P(F) - P(E and F)

P(E or F) = P(E) + P(F) - P(E)*P(F)

P(E or F) = 0.4 + 0.5 - 0.4*0.5

P(E or F) = 0.4 + 0.5 - 0.2

P(E or F) = 0.9 - 0.2

P(E or F) = 0.7

The equation of line in slope - intercept form is, y = 2x - 13.

What is slope-intercept form of the line?

Using a straight line's slope and the location of its y-axis intersection, the slope intercept equation can be used to determine the general equation of the line. y = mx + b is the equation in slope intercept form.

Consider the given equation of line y = 2x + 1.

And the point given is, (6, -1).

We have to find the equation of line parallel to the given line and passes through the point (6, -1).

First we have to find the slope of the parallel line.

Since, Slope of the parallel line is same as the slope of the given line.

Here, the slope of the line is 2.

So, the slope of the parallel line is also 2.

Now consider the point slope form of the line,

[tex]y-y_1=m(x-x_1)[/tex]

Plug [tex](x_1, y_1)=(6, -1) , m = 2[/tex]

⇒

[tex]y-(-1)=2(x-6)\\y+1=2x-12\\y=2x-12-1\\y=2x-13[/tex]

Hence, the equation of the line parallel to the given line in slope intercept form is, y = 2x - 13.

For a parallelogram having (∠1 and ∠3) and (∠2 and ∠4) as the two pairs of opposite angles, if [∠2 = (4x - 20)] and [∠4 = (3x - 11)], then the measure of ∠1 will be 164°.

As per the question statement, a parallelogram has (∠1 and ∠3) and         (∠2 and ∠4) as the two pairs of opposite angles, and [∠2 = (4x - 20)] and [∠4 = (3x - 11)],

Then, we are required to calculate the measure of ∠1.

To solve this question, first we will need to know about two important properties of a parallelogram,

(a) The sum of all the four interior angles of a parallelogram is equal to 360°,

(b) Opposite angles of a parallelogram are equal.

Now since our concerned parallelogram has (∠1 and ∠3) and (∠2 and ∠4) as the two pairs of opposite angles,

Therefore, (∠1 = ∠3) and (∠2 = ∠4),

And [(4x - 20) = (3x - 11)]...[∵(∠2 = ∠4)]

Or, [(4x - 3x) = (20 - 11)]

Or, [x = 9]

Therefore, [∠2 = ∠4 = (4x - 20) = 16°].

Now, [(∠1 + ∠2 + ∠3 + ∠4) = 360°]

Or, [(∠1 + ∠2 + ∠1 + ∠2) = 360°]...[∵(∠1 = ∠3) and (∠2 = ∠4)]

Or, [{(∠1 + ∠1 ) + (∠2 + ∠2)} = 360°]

Or, [(2∠1 + 2∠2) = 360°]

Or, [2∠1 = {360 - (2 * 16)}°]

Or, [2∠1 = (360 - 32)°]

Or, [2∠1 = 328°]

Or, [∠1 = (328/2)°]

Or, [∠1 = 164°]

That is, for a parallelogram having (∠1 and ∠3) and (∠2 and ∠4) as the two pairs of opposite angles, if [∠2 = (4x - 20)] and [∠4 = (3x - 11)], then the measure of ∠1 will be 164°

Answer:

a) $4089.55

b) $19089.55

c) $56.80

Step-by-step explanation:

a) (100 + 4.1)/100 = 1.041. So, 15000 × 1.041⁶ = 19089.55. Interest that will be paid: 19089.55 - 15000 = $4089.55 (2 dp).

b) $19089.55 (with interest and principal)

c) 4089.55/72 = $56.80

The amount of interest he would pay for a  loan of $10,000 with a 2% interest rate and for 18 months is $300

Amount of money taken as a loan = $10000

The rate of interest = 2%

The time period of interest is 18 months = 1.5 year

Interst = prt/100

= 10000x 2 x 1.5/100

= 300

Therefore, the amount of interest he would pay for a  loan of $10,000 with a 2% interest rate and for 18 months is $300

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its translations into various languages can vary slightly.

Finding the values of the variables that result in the equality is the first step in solving an equation with variables.

Let E represent Economy

Let L represent Luxury

Let M be the number of miles driven

Let C be how much it cost to rent a luxury car than economy

E = -0.70M + 11.95

L = 1.25M + 17.30

C = L - E

C =(1.25M + 17.30) - (-0.70M + 11.95)

C = 1.25M + 17.30 + 0.70M - 11.95
