What is more than two numbers are added for example consider the number 3+5+7

1 answer:

4 0

What you do is take two of the numbers and add them together then you take the sum (what you get after you add the two numbers) then add them to the third number and if there are more numbers then you can take the sum of the three numbers and add the fourth and so on

f(x) = 4x^2+2x+6 What is the value of the discriminant of f? How many distinct real number zeros does f have?

Sauron [17]

Answer:

The value of Discriminant of the function is -92

It has ZERO distinct real number zeros.

Step-by-step explanation:

Given:

$f(x)=4x^{2} +2x+6$

Which is a Quadratic Equation in the general form of

$ax^{2}+bx+c=0$

where a,b and c are constants.So on comparing the given equation with general form we get,

$a=4\\b=2\\c=6$

Formula for discriminant we have

$Discriminant=b^{2}-4ac\\ =2^{2}-4(4)(6)\\ =4-96\\=-92$

now for zeros we have

$x=\frac{-b+\sqrt{b^{2-4ac} } }{2a} \\or\\x=\frac{-b-\sqrt{b^{2-4ac} } }{2a} \\$

on substituting these values we get

$x=\frac{-2+\sqrt{-92} }{8}$

$x=\frac{-2-\sqrt{-92} }{8}$

the term $\sqrt{-92}$ is imaginary

hence the zeros are not real number

Tanya [424]

This is the case of Inductive Arguments. In logic, inductive arguments are all about the content of the premises and involve probability. Logicians focus on the strength of this type of argument. In a strong inductive argument, if the premises are assumed true, it is likely that the conclusion is true, it does not mean that it must be true, it is possible that the conclusion could be false. Thus, if the conclusion is likely to not be true based on the assumed truth of the premises, the inductive argument is weak.

While there are mathematical ways to determine probability, most of the time you'll have to use your intuition and experience to help you figure out whether an inductive argument is strong or weak.

So according to this, given that Ryan is conducting an observational study on human behavior in different environments. To get the most accurate conclusion he needs to get the greatest sample size, that is 50 Individuals.
