MANOVA is a variation of ANOVA that allows us to identify and remove the effects of a third variable and increase statistical power.
Multivariate ANOVA (MANOVA) extends the capabilities of analysis of variance (ANOVA) by assessing multiple dependent variables simultaneously. ANOVA statistically tests the differences between three or more group means. For example, if we have three different teaching methods and you want to evaluate the average scores for these groups, we can use ANOVA. However, ANOVA does have a drawback. It can assess only one dependent variable at a time. This limitation can be an enormous problem in certain circumstances because it can prevent us from detecting effects that actually exist.
This statistical procedure tests multiple dependent variables at the same time. By doing so, MANOVA can offer several advantages over ANOVA.

What is the end behavior of the graph of the polynomial function f(x) = –x5 + 9x4 – 18x3?
The end behavior of the graph of the polynomial function:
As x approaches ∞, y approaches -∞
As x approaches -∞, y approaches ∞
What is an end behavior?
The behavior of the function graph at the "ends" of the x-axis is known as the end behavior of a function, or f.
Here, we have
f(x) = –x⁵ + 9x⁴ – 18x³
F(x) is a fifth-degree (odd function ) with a negative leading coefficient
If the exponent is odd and the leading coefficient is negative then the end behavior is
As x approaches ∞, y approaches -∞
As you go on the right, f(x) goes down
As x approaches -∞, y approaches ∞
As you go on the left, f(x) goes up.
Hence, the end behavior of the graph of the polynomial function: As x approaches ∞, y approaches -∞

Graph the equation:
y - 2 = 3 (x - 2)
Answer:
See below and attached graph
Step-by-step explanation:
If you are using a graphing calculator it is a breeze. You write down the equation as it is and it should plot it, depending on what calculator you use.
If you are doing this manually here are the steps
We are given y - 2 = 3(x-2)
Expand the brackets on the right hand side
3(x - 2) = 3x - 6
So the original equation becomes
y - 2 = 3x - 6
Adding 2 to both sides
y - 2 + 2 = 3x -6 + 2
y = 3x - 4 [1]
This form of equation is known as a slope-intercept form of the line
We need two points to plot a line. This can be done by choosing a value for x, finding the y value which gives one point. Then repeat for another value of x to get y for that value giving another point. Draw a straight line through both points
Point 1
Let's choose x = 2 and plug this into the equation [1]
y = 3·2 - 4 = 6- 4 = 2.
So (2, 2) is one point on the graph
Point 2
Choose another value for x, say x = 4
y = 3·4 - 4
y = 12-4
y = 8
So (4, 8) is another point
Draw a line through these two points

If the probability that the Islanders will beat the Rangers in a game is 0.87,
what is the probability that the Islanders will win exactly zero out of six
games in a series against the Rangers? Round your answer to the nearest
thousandth.
Answer:
0.002
Step-by-step explanation:
The probability that the Islanders will win exactly zero out of six games in a series against the Rangers is 0.002. To find this probability, you need to use the binomial probability formula. This formula calculates the probability of a certain number of successes in a series of independent trials, given the probability of success in a single trial. In this case, the probability of success is 0.87, and the number of trials is 6. The number of successes is 0, because the Islanders are not expected to win any of the games. Plugging these values into the formula, we get:
P(exactly 0 successes) = (6 choose 0) * (0.87^0) * (1 - 0.87)^6
= 1 * 1 * (1 - 0.87)^6
= 0.002
Therefore, the probability that the Islanders will win exactly zero out of six games in a series against the Rangers is 0.002.

What is a function?Functions are relationships that exist between a set of inputs and outputs. A function is an association of inputs, where each input is directly linked to one or more outputs. Range, codomain, and domain are all attributes of each function.
The given functions are:
f(x) = (3.6)ˣ⁺²
And g(x) = (3.6)³ˣ⁺¹
To find (f ÷ g)(x):
We take division of f(x) by g(x).
(f ÷ g)(x) = f(x) ÷ g(x)
(f ÷ g)(x) = (3.6)ˣ⁺² ÷ (3.6)³ˣ⁺¹
(f ÷ g)(x) = (3.6)ˣ⁺² ÷ (3.6)³ˣ⁺¹
(f ÷ g)(x) = (3.6)ˣ⁺² / (3.6)³ˣ⁺¹
Simplifying,
(f ÷ g)(x) = (3.6)ˣ (3.6)² / (3.6)³ˣ (3.6)¹
(f ÷ g)(x) = (3.6)ˣ⁻³ˣ (3.6)
(f ÷ g)(x) = (3.6)⁻²ˣ (3.6)

We know that the required value of y is -17 using the slope formula.
What is the slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
The slope of a line can be used to gauge how steep it is.
The slope is theoretically determined as "rise over run" (change in y divided by change in x).
So, we have the slope 5/2.
The points are: (−6, y) and (4, 8)
The slope formula: m = y2 - y1/x2 - x1
Now, insert the values and calculate y as follows:
m = y2 - y1/x2 - x1
5/2 = 8 - y/4 + 6
5/2 = 8 - y/10
5/2 * 10 = 8 - y
25 = 8 - y
-y = 25 - 8
-y = 17
y = -17

the measure of ∠LPM is 90°

Define Rhombus.
A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral. In a rhombus, opposite sides are parallel and the opposite angles are equal.
For a Rhombus, LMNO
∠LON = 102°
NP = 5 units
By the properties of Rhombus, we know that
All sides of a rhombus are congruent (equal)
So, LM = MN = NO = OL
and
Opposite angles are equal and the opposite sides are parallel.
So, ∠LON = 102° = ∠LMN
Since Adjacent angles add up to 180°.
Therefore ∠L + ∠M = 180°
∠M + ∠N = 180°
∠N + ∠O = 180°
∠O + ∠L = 180°
So, ∠N = 180° - ∠O = 180° - 102° =78°
∠L = 180° - ∠O = 180° - 102° =78°
∠M = 180° - ∠L = 180° - 78° =102°
Diagonals bisect each other at 90° or we can also say that each of the two diagonals in a rhombus is the perpendicular bisector of the other.
So, ∠LPM = ∠NP0 = ∠MPN = ∠LPO =90°
Thus, the measure of ∠LPM is 90°
the measure of ∠PMN is 102°
the length of LN is 10 units.

Thank you
I'll go over problem 9 part (a) to get you started.
The sine rule, aka law of sines, is this
[tex]\frac{\sin(A)}{a} = \frac{\sin(B)}{b} = \frac{\sin(C)}{c}[/tex]
where the uppercase letters A,B,C are the angles and the lowercase letters a,b,c are the sides opposite those respective angles. Eg: angle B is opposite side b.
Some textbooks may have the lowercase letters up top, but it doesn't matter since it's the same ratio. All that matters is things stay consistent. The lowercase letters must be together on the same level, and same goes for the uppercase letters on their own separate level.
We can then break up that equation into these 3 separate equations, to make things more bite-sized so to speak.
[tex]\frac{\sin(A)}{a} = \frac{\sin(B)}{b}\\\\\frac{\sin(B)}{b} = \frac{\sin(C)}{c}\\\\\frac{\sin(A)}{a} = \frac{\sin(C)}{c}\\\\[/tex]
Let's focus on the 3rd equation and do a bit of algebraic manipulation like so
[tex]\frac{\sin(A)}{a} = \frac{\sin(C)}{c}\\\\\sin(A) = \frac{a\sin(C)}{c}\\\\\frac{\sin(A)}{\sin(C)} = \frac{a}{c}\\\\[/tex]
Through similar steps, we can say:
[tex]\frac{\sin(B)}{b} = \frac{\sin(C)}{c}\\\\\sin(B) = \frac{b\sin(C)}{c}\\\\\frac{\sin(B)}{\sin(C)} = \frac{b}{c}\\\\[/tex]
-------------------------------------------
To summarize the previous section, we found that:
[tex]\frac{\sin(A)}{\sin(C)} = \frac{a}{c}\\\\\frac{\sin(B)}{\sin(C)} = \frac{b}{c}\\\\[/tex]
It then allows us to do the following steps for problem 9, part (a)
[tex]\frac{a+b}{c} = \frac{\sin(A)+\sin(B)}{\sin(C)}\\\\\frac{a+b}{c} = \frac{\sin(A)}{\sin(C)}+\frac{\sin(B)}{\sin(C)}\\\\\frac{a+b}{c} = \frac{a}{c}+\frac{b}{c}\\\\\frac{a+b}{c} = \frac{a+b}{c}\\\\[/tex]
We have confirmed that the equation in problem 9 part (a) is indeed an identity. Take note how I kept the left hand side the same the entire time while the right hand side transformed into the left side.
Similar steps will be taken for problem 9, part (b). I'll let you do that part.

each trial has a single possible outcome each trial has an equal chance of success each trial is either independent of the others or mutually exclusive.As opposed to a continuous distribution, like the normal distribution, the binomial distribution is a frequent discrete distribution used in statistics.
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.
The result is then multiplied by the sum of the number of attempts and the number of successes.
