Answer:
[tex]\frac{5}{11}[/tex]
Step-by-step explanation:
30 regular flavors.
25 watermelon flavors.
Add them both and you get:
55.
Turn that into a fraction:
[tex]\frac{25}{55}[/tex]
The reason the numorator is 25 is because there are 25 watermelon flavors and 55 flavors total.
Find the GCD (or HCF) of numerator and denominator.
The GCD of 25 and 55 is 5.
Divide both the numerator and denominator by the GCD
25 ÷ 5 = 5
55 ÷ 5 = 11
Reduced fraction:
[tex]\frac{5}{11}[/tex]
Therefore, [tex]\frac{25}{55}[/tex] simplified to lowest terms is:
[tex]\frac{5}{11}[/tex]
Therefore, the answer is: [tex]\frac{5}{11} \\[/tex]

Jamie and Billy each think of a polynomial. Each of their polynomials is monic, has degree 3, and has the same positive constant term and the same coefficient of x. The product of their polynomials is x^6 +2x^5 +2x^4 +18x^3 + 33x^2+40x+16.
b)What is the coefficient of x of jamie's polynomial?
c)what are the two polynomials?
Answer:
b) the coefficient of x of jamie's polynomial is 5 .
c) The two polynomials are :
x³ + 4x² + 5x + 4
x³ - 2x² + 5x + 4
Step-by-step explanation:
consider these two Monic polynomials of degree 3:
P : x³ + ax² + bx² + c
Q : x³ + a₁x² + bx² + c
P × Q = x⁶+ (a+a₁)x⁵ + (aa₁+2b)x⁴ + (ab+a₁b+2c)x³ + (ac+a₁c+b²)x² +2bcx + c²
Now we compare the coefficients of P × Q and x⁶ + 2x⁵ +2x⁴ + 18x³ + 33x² + 40x + 16
b)
c² = 16 ⇒ c = 4 (c is positive)
2bc = 40 ⇒ 8b = 40 ⇒ b = 5 then the coefficient of x of jamie's polynomial is 5 .
c)
In order to find a and a₁ we need to solve this system:
a+a₁ = 2 a+a₁ = 2
⇔
aa₁+2b = 2 aa₁ = -8
Solve the system and you’ll get :
a = 4 and a₁ = -2 or a = -2 and a₁ = 4
Let’s choose a = 4 and a₁ = -2 then
the two polynomials are respectively:
P : x³ + ax² + bx² + c = x³ + 4x² + 5x + 4
Q : x³ + a₁x² + bx² + c = x³ - 2x² + 5x + 4

11.) A restaurant chain's owners are trying to decide if they want to open up a franchise in your
town. To help them decide, they want to find out how often people in your town go out to eat. A researcher interviews people leaving a local restaurant. Is there a bias in this sampling
method? Explain.
12. Is there any bias in the following survey question? Explain.
Do you prefer delicious chocolate ice cream or boring vanilla ice cream?
Answer:
11. The sampling method is biased. This is because the researcher only interviews people coming out of the restaurant instead of people in the restaurant or walking on the street. This would be called convenience sampling.
12. There is bias in the question. The writer prefers chocolate over vanilla by the words used to describe the two flavors.

6,480 US Dollar USDShow how to add 2 1/2+ 4/5 using the number line below
Answer:
Start at 2 1/2 plot that. Then go to 3 3/10 which is 3 right of the whole number 3 and plot it. Lastly, draw lines or bumps to represent going from 2 1/2 to 3 3/10.
Step-by-step explanation:
The Simplest way (This includes the graphing part but I advise you to use the addition steps first)
I always like to convert mixed numbers into decimals.
2 1/2 is 2.5 and 4/5 is 0.8.
2.5 + 0.8 = 3.3 which is 3 3/10
Graph:
2 1/2 should be in the middle of the whole numbers 2 and 3.
That is your starting point.
Now to add 4/5 which is 0.8 you could do 2.5 + 0.8 = 3.3
You need to find your ending point.
Your ending point should be 3 tickmarks to the right of 3.
Now, you could draw hop marks or arrows starting from 2 1/2 to 4/5
Addition Steps:
First, convert 2 1/2 to an improper fraction.
2x2 + 1 = numerator.
4+1 = 5
5/2 is 2 1/2.
Now you need to find a common denominator for 2 and 5.
This should be 10.
Multiply 5/2 by 5/5
Multiply 4/5 by 2/2
25/10 and 8/10 should be the answers
Now do 25+8 but keep the denominator 10.
25+8 is 33/10.
You could convert it to 3.3 which is 3 3/10
3 3/10 is on your number line.

It cannot be determined without solving.
So, in response to the above question, we can state that equation the response is: There are countless options.
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical. For examples, in the equation 3x + 5 = 14, because equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The emblem and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
The two lines' equations are y = 1/4 (x - 4) and y = 1/4 (x - 1)
By equating them, we obtain: 1/4(x - 4) = 1/4x - 1.
To get rid of the fractions, multiply both sides by 4 as follows: x - 4 = x - 4
This equation may be written as 0 = 0, which is a constant.
The two lines coincide and have an endless number of solutions as a result.
Hence, the response is: There are countless options.

Quadratic functions g (x) and h (2) are graphed on the same coordinate gri
The vertex of the graph of h (2) is 12 units above the vertex of the graph
of g (2).
Which pair of functions could have been used to create the graphs
The derivative of h(x) in A is 2x+24
h'(x)=0 g'(x)=0
2x+24=0 2x=0
x=-12 x=0
Similarly the derivative of h(x) in D is 2x-24
h'(x)=0 g'(x)=0
x=12 x=0
Knowing that B & C give the same x-value when solving for the derivative=0We know that the only difference comes down to the y-value when substituting x=0 in h(x).
The y-value of the vertex of h(x) must be +12 the y-value of the vertex of g(x).
We have to add 12 to get to the x-value, which means that the third option or C is your answer.

Step-by-step explanation:
Angle E is an inscribed angle ....inscribed angle will intercept twice as many degrees of arc as the angle measure
angle measure = 62 twice as many degrees of arc = 124 (b-c-d)
bc = 64 so cd = 60 for the total of 124

Find the total cost of an $849.50 laptop after including 6% sales tax.
Answer:
$900.47
Step-by-step explanation:
you minus $50.47 (%6) from $900.47
The total cost of an $849.50 laptop after adding a 6% sales tax will be equal to $900.47.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the data provided in the question,
Price of laptop = $849.50
A tax of 6% on the Price of the laptop, so the tax will be,
849.50 × 6/100 = $50.97
Then, the total cost of the Laptop will be,
$849.50 + $$50.97 = $900.47

A student randomly selects two buttons from a box containing 32 red buttons, 48 blue buttons, 44 green buttons, and 51
yellow buttons. Compute the probability, as a decimal ratio with four decimal places, of selecting two red buttons.
The probability of drawing two red buttons is:
P = 0.0326
How to get the probability?There are:
32 red buttons.48 blue buttons.44 green buttons.51 yellow buttons.So there are a total of 32 + 48 + 44 + 51 = 175
We assume that all the buttons have the same probability to being randomly drawn.
For the first button, the probability of drawing a red one is equal to the quotient between the number of red buttons and the total number of buttons:
p = 32/175
For the second button the probability is computed in the same way, but now there are 31 red buttons and 174 buttons in total, so we have:
q = 31/174
Finally, the joint probability is given by the product between p and q, this gives:
p*q = (32/175)*(31/174) = 0.0326
