Kim's method of sampling the students in the given scenario is said to; It is not a random survey.

<h3>What is a random sample?</h3>

Random sampling is defined as a sampling technique whereby each sample has an equal probability of being chosen. This means that a sample chosen randomly is meant to be an unbiased representation of the total population.

In this question, we are told that Kim asked the first 50 kids to school in the morning about a question and used their responses to arrive at a conclusion.

Now, Kim's method is not random because it is biased as only those who came earliest were asked.

Which is the best first step to write this in standard form?
goldenfox [79]

Answer:

<em>Set the function equal to 0</em>

Step-by-step explanation:

<u>Standard Form of the Quadratic Equation</u>

The form

ax^2+bx+c=0

is called the standard form of a quadratic equation. It can be clearly identified the terms of a second-degree polynomial equated to 0.

The equation is given in the form:

2(x-4)^2-3=8

And we need to operate the expression to make it look like a standard form. The first logical step should be to set the function equal to 0 and then start to operate the resulting expression. It can be done by subtracting 8 on both sides of the equation:

2(x-4)^2-3-8=0

Answer: Set the function equal to 0

Someone Please Help.
ahrayia [7]

Hi there!

\large\boxed{f(-6) = 5}

The value of f(-6) is the y-value at the x-coordinate x = -6.

Looking at the graph, we can see that at x = -6, y = 5.

Therefore, f(-6) = 5.

How do you decide which variable to isolate in order to use the substitution method to solve a system of linear equation?​
Kazeer [188]
It doesn’t really matter which variable you isolate first but usually you would use the one that’s by itself already. like for example one of the equations was y = 8. you would already have your y solve for so you would just have to plug that in for y in the other equation. personally, i usually do x first unless one of the equations has either x or y by itself already. i think its easier to just do x first and then solve for y after that, but it just depends on what the equations are; sometimes it might be easier to just do y first. hope this helps!
