Y=2X squared -12 X +20 for quadratic formula
Answers
x = (12 ± √(-16)) / 4,The solutions would be complex numbers.
What is the quadratic formula?To solve quadratic equations of the form ax2 + bx + c = 0, use the quadratic formula. For this situation, your condition is as of now as a quadratic condition, with a = 2, b = - 12, and c = 20.
The quadratic formula is:
x = (-b ± √\((b^2 - 4ac)\)) / 2a
Plugging in the values for a, b, and c, we get:
x = (-(-12) ± √\(((-12)^2 - 4(2)(20)))\) / 2(2)
Simplifying the expression inside the square root:
x = (12 ± √\((144 - 160)\)) / 4
x = (12 ± √(-16)) / 4
Since the square foundation of a negative number is definitely not a genuine number, this condition has no genuine arrangements. Complex numbers would provide the answers.

Use a common denominator to find equivalent fractions for and Enter the correct fractions in the boxes. 5 12
Answers
6/12 and 5/12
1) Equivalent fractions are fractions that keep the same ratio, like:
1/2 , 2/4, 4/8, etc.
2) To find an equivalent fraction for:
\(\frac{1}{2}\text{ and }\frac{5}{12}\)Using a Common Denominator, let's prime factorize those denominators, we have 12, as the LCM
So 1/2 is equivalent to 6/12 and 5/12 is equivalent to itself.

What is the probability that out of 60 lambs born on BaaBaa Farm, at least 35 will be male? Assume that males and females are equally probable, and round your answer to the nearest tenth of a percent.
A. 12.3%
B. 4.6%
C. 25.9%
D. 44.9%
Answers
Answer:
A. 12.3%
Step-by-step explanation:
Model this as a binomial distribution
\(X \sim B(n,p)\) where X is the random variable, n is the number of trials, and p is the probability of success.
Therefore,
X = lambs born malen = 60p = 0.5(If the probability of lambs being male and female is equal, then the probability of males being born = 0.5)
\(X \sim B(60,0.5)\)
The probability that at least 35 lambs will be born male:
\(\ \ \ \ \ \ \ P(X\geq 35)=1-P(X\leq 34)\\\\\implies P(X\geq 35)=1-0.8774695851...\\\\\implies P(X\geq 35)=0.1225304149\\\\\implies P(X\geq 35)=12.3 \%\)

HELP! Which input-output tables represent a function? Select ALL correct answers.
Answers
Reason = if there are two of the same number in the input or output it is not a function.
The input-output tables represent a function that will be table C and table D.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
If the value of the output is single for each distinct value of the input. Then the table represents the function.
In option A, the number of outputs is 2 for a single value of the input that is x = 1. So, it does not represent a function.
In option B, the number of outputs is 2 for a single value of the input that is x = 5. So, it does not represent a function.
In option E, the number of outputs is 2 for a single value of the input that is x = 1. So, it does not represent a function.
The input-output tables represent a function that will be table C and table D.

A -425
B 1,200

D-2,525
Answers
Answer:
Step-by-step explanation:
Essentially, recall what an absolute value function is.
When you plug number into an absolute value function, or make it an absolute value, you will ALWAYS get a positive version of that number.
When the question asks, what number could be the absolute value of another number, it's asking you what is a possible outcome of making a number an absolute value.
Since we know that making any number an absolute value, makes that number positive. We can get rid of all of the negative answers.
You are left with B.
Answer:
B. 1200
Step-by-step explanation:
Absolute value is the non-negative version of a number/variable. Whether the sign is negative or positive, the absolute value is always positive.

The given sequence is
-4 , 0 , 4 , 8 , ......
the given sequence is arithmetic sequence
because there is a common difference between the terms of the sequence
common difference = 0 - (-4) = 4
as a check = 4 - 0 = 4 and 8 - 4 = 4

Please help me important question in image
Answer:
The equation a=0.003x^2+21.3 models the average ages of women when they first married since the year 1940 in the United States. In this equation, a represents the average age and x represents the years since 1940. To estimate the year in which the average age of brides was the youngest, we need to find the minimum value of the quadratic function a=0.003x^2+21.3. This can be done by using the formula x=-b/2a, where b is the coefficient of x and a is the coefficient of x^2. In this case, b=0 and a=0.003, so x=-0/(2*0.003)=0. This means that the average age of brides was the lowest when x=0, which corresponds to the year 1940. The value of a when x=0 is a=0.003*0^2+21.3=21.3, so the average age of brides in 1940 was 21.3 years old. This is consistent with the historical data, which shows that the median age of women at their first wedding in 1940 was 21.5 years old. The average age of brides has been increasing since then, reaching 28.6 years old in 2021.

The area of the composite figure is 122.24 units².
How to find the area of a composite figure?The composite figure consist of a rectangle and two semi circles. Therefore, the area of the composite figure is the sum of the area of the individua shapes.
Hence,
area of the composite figure = area of the rectangle + 2(area of semi circle)
Therefore,
area of the composite figure = 9 × 8 + 2(1 / 2 πr²)
area of the composite figure = 72 + πr²
where
r = 8 / 2 = 4 units
Therefore,
area of the composite figure = 72 + 3.14 × 4²
area of the composite figure = 72 + 3.14 × 16
area of the composite figure = 72 + 50.24
area of the composite figure = 122.24 units²
