What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the first function be represented as f ( x )
Let the second function be represented as g ( x )
Now , to solve a system of two equations graphically, we need to graph both equations on the same coordinate plane and find their point of intersection. This point represents the solution to the system
So , the point of intersection of the graphs is
A ( 2 , 0 ) and B ( 0 , -4 )
Hence , the solution is A ( 2 , 0 ) and B ( 0 , -4 )

Jeanette really loves apple-flavored Fruity Tooty candies, but there always seems to be a lot of cherry-flavored candies in each bag. To determine whether this is because cherry candies are so popular or because each bag contains fewer apple candies, Jeanette randomly picks a Fruity Tooty candy from her bag, records its flavor, and places it back in the bag. Each bag contains a mixture of cherry, grape, apple, lemon, and orange flavors. Which statement about Jeanette's distribution of sample proportions is true?
A) The count of drawing an apple candy is not a binomial distribution.
B) The distribution of the count of picking a cherry candy cannot be modeled as approximately normal if Jeanette picks candies over 100 times.

27 is 50% of what number?
Answer:
27 is 50% of 54
Step-by-step explanation:
27 x 2 is 50% x 2
54 is 100%
☁️ Answer ☁️
27 is 50% of 54
We assume, that the number 50 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 50, so we can write it down as 100%=50.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=50
2) x%=27
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=50/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 27 is what percent of 50
100%/x%=50/27
(100/x)*x=(50/27)*x - we multiply both sides of the equation by x
100=1.85185185185*x - we divide both sides of the equation by (1.85185185185) to get x
100/1.85185185185=x
54=x
x=54

The angle of the right-angled triangle using trigonometric ratio is 34.84°.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The diagram shows the right-angled triangle.
The hypotenuse side, h = 28
The perpendicular side, p =16
The trigonometric ratio that relates hypotenuse side and the perpendicular side is sine θ.
[tex]Sine \theta=\frac{perpendicular}{hypotenuse}[/tex]
⇒ [tex]Sine\theta = \frac{16}{28}[/tex]
⇒ [tex]Sine \theta=0.5714[/tex]
⇒ [tex]\theta = Sine^{-1} (0.5714)[/tex]
⇒ [tex]\theta = 34.84[/tex]
Hence we can conclude that the angle of the right-angled triangle using trigonometric ratio is 34.84°.

The sum of two consecutive integers is three times their difference. what is the larger number?
Answer:
[tex]\huge\boxed{2}[/tex]
Step-by-step explanation:
In order to find the two consecutive numbers, we have to note that a consecutive number is one that is just after the previous.
Such: 4, 5, 6 are consecutive. 12, 69, 42 are not.
Therefore - we can represent our first number as [tex]x[/tex] and our second as [tex](x+1)[/tex].
Let's make an equation based on the problem.
"The sum of two consecutive integers"
[tex]x + (x+1)[/tex]"3 times their difference"
[tex]3(x - (x+1))[/tex]We can now set these equal to each other.
[tex]x + (x+1) = 3(x - (x+1))[/tex]Let's solve for x.
[tex]2x + 1 = 3(1)[/tex] (Combine like terms) [tex]2x+1=3[/tex] (Multiply the right side) [tex]2x = 2[/tex] (Subtract 1 from both sides) [tex]x=1[/tex] (Divide both sides by 2)Now we know that our first number is 1. Therefore, since our second number is one greater, our second number will be [tex]1+1=2[/tex].
The question asks for the larger number. 2 is larger than 1, therefore 2 is our answer.

A simple random sample of 140 residents in a certain town was polled the week after the Super Bowl. 75 of them reported that they watched the game on TV. a) Construct the 95% CI for the proportion of people that watched Super Bowl. b) The prognosis stated that the proportion of people watching the game is 48.1%. Does this prognosis contradict your findings
Answer:
a) The 95% CI for the proportion of people that watched Super Bowl is (0.4531, 0.6183).
b) 48.1% = 0.481 is part of the confidence interval, which means that this prognosis does not contradict the findings.
Step-by-step explanation:
a) Construct the 95% CI for the proportion of people that watched Super Bowl.
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
75 out of 140 watched the Super Bowl:
This means that [tex]n = 140, \pi = \frac{75}{140} = 0.5357[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5357 - 1.96\sqrt{\frac{0.5357*0.4643}{140}} = 0.4531[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5357 + 1.96\sqrt{\frac{0.5357*0.4643}{140}} = 0.6183[/tex]
The 95% CI for the proportion of people that watched Super Bowl is (0.4531, 0.6183).
b) The prognosis stated that the proportion of people watching the game is 48.1%. Does this prognosis contradict your findings
48.1% = 0.481 is part of the confidence interval, which means that this prognosis does not contradict the findings.

D: -5
Answer:

Step-by-step explanation:
The total number of dogs in a farm is 10.
What is linear equation in one variable?The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the given question.
Total number of legs = 50
The total number of animals in a farm = 15
Let the total number of dogs be x.
⇒ Total number of legs of x dogs = 4x
Also, Total number of legs of all chickens = 2(15 - x)
Since, dogs have four legs and chickens have 2 legs.
So, according to the given situation we have a linear equation in one variable
[tex]2(15-x)+4x = 50[/tex]
For finding the number of dogs we have to find the value of x for the above linear equation in one variable.
Therefore,
[tex]2(15-x)+4x = 50[/tex]
[tex]\implies 30 - 2x + 4x = 50[/tex]
[tex]\implies 30 +2x = 50[/tex]
[tex]\implies 2x = 50 -30[/tex]
[tex]\implies 2x = 20[/tex]
[tex]\implies x = \frac{20}{2}[/tex]
[tex]\implies x = 10[/tex]
Therefore, the total number of dogs in a farm is 10.

A jewelry store offers its own brand of customizable charm bracelets. You are able to choose from 9 different charms for your bracelet. What is the minimum number of unique charms that must be available if the jeweler wants to advertise that it offers over 30,000 different charm bracelets?
The minimum number of unique charms that must be available is 18
How to determine the minimum number of unique charms that must be available?The given parameters are
Offers = minimum of 30000
Different charms, r = 9
Represent the minimum number of unique charms that must be available with n
So, we have the following combination equation
nCr = Total offers
Apply the combination formula
So, we have
n!/(r!(n- r)!) = Total offers
Substitute the known values in the above equation
n!/(9!(n- 9)!) >= 30000
Multiply through by 9!
So, we have
n!/(n- 9)! >= 10886400000
Next, we divide the left-hand side by (n - 9)!
So, we have
n x (n - 1) x ..... x (n-8) >= 10886400000
Next, we continue solving by trial by error
After several trials, we have:'
n = 18
To check:
18 x (18 - 1) x ..... x (18 - 8) >= 10886400000
17643225600 >= 10886400000 --- true
Assume n = 17, we have
17 x (17 - 1) x ..... x (17 - 8) >= 10886400000
8821612800 >= 10886400000 --- false
