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 maximum value of the function z is 120

The objective function is given as

z = 8x + 3y

While the constraints are given as

x + y ≤ 15

2x + y ≤ 18

x ≥ 0 and y ≥ 0

To determine the feasible region, we simply plot the graphs of x + y ≤ 15 and 2x + y ≤ 18

And we subset the graph to where x ≥ 0 and y ≥ 0

From the graph, we have the feasible coordinates to be

(x, y) = (0, 18), (3, 12) and (15, 0)

Substitute (x, y) = (0, 18), (3, 12) and (15, 0) in z = 8x + 3y

z = 8(0) + 3(18) = 54

z = 8(3) + 3(12) = 60

z = 8(15) + 3(0) = 120

Hence, the maximum value is 120

The value of the function f(5) is - 17.

A linear function is a function that represents a straight line on the coordinate plane.

A linear function in slope intercept form is as follows:

y = mx + b

where

Therefore, for the linear function,  f(4) = −13 and  f(−4) = 19.

f(5) can be found as follows;

-13  = 4m + b

19 = -4m + b

2b = 6

b = 6  /2

b = 3

-13 - 3 = 4m

-16 = 4m

The volume of the right circular cone is, 131.95 cubic centimeter.

What is cone?

A cone is a smooth-tapering three-dimensional geometric object with a flat base and an apex or vertex. The base of a cone is made up of all the points on a plane other than the apex, and the apex is connected to all the other points on the base by a series of line segments, half-lines, or lines.

Here, the radius, r = 3 cm, and height h = 14 cm.

We have to find the volume of right circular cone.

Since,

Volume = [tex]\pi r^2\frac{h}{3}[/tex]

[tex]V = \pi (3)^3(\frac{14}{3})\\ V = \pi (3)(14)\\V = 42\pi \\V = 131.95 cm^3[/tex]

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°

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

The unknown variable t has a value of t = (V - 7πr²)/6πr

From the question, we have the following parameters that can be used in our computation:

Formula; V = 6πrt+7πr*2

Rewrite the formula properly

So, we have the following representation

V = 6πrt + 7πr²

Subtract the expression 7πr² from both sides of the equation

So, we have

V - 7πr² = 6πrt + 7πr² - 7πr²

Evaluate the difference

V - 7πr² = 6πrt

So, we have

6πrt/6πr = (V - 7πr²)/6πr

Evaluate

V - 7πr² = 6πrt

Now you have a single term with t on the right side and two terms without t on the left side.

It follows from the task content that the maximum height reached by the rocket is to be determined.

The given function is; h (t) = -16 t² + 72t + 7.

Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.

Therefore; at maximum height;

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
