When you divide a number by two, you find the number that if you add it to itself, become the original number.
When you square root a number, you find the smaller number that becomes the bigger number if you multiply it by itself.
For sixteen, if you divide it by two, you get 8, while if you square root it, it becomes 4.
A^2 + b^2 = c^2
12^2 + 17^2 = 485
so c^2=485
so c=22.0 inches
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.

We write the equation in the form of directional.
y -1 = 6x ⇔ y = 6x + 1
y - 1 = 3x ⇔ y = 3x + 1
y - 7 = 2x - 6 ⇔ y = 2x - 6 + 7
y = 2x + 1
y - 7 = x - 2 ⇔ y = x - 2 + 7
y = x + 5
Equations cleverly arranged .
Point Q = (0,1)
b factor , not only fits the last equation
In the drawing have engraved points Q and R are tangent linear function appropriate to that point . This graphics solution . y = 3x + 1
Answer b
