Answer: I can't answer that, you'll need to know the quadrant.

Step-by-step explanation:

Quadrants are not numbered clockwise or counterclockwise, but instead are labeled by letter.

However, some people might approximate the distance mathematically with something like this equation: =sqrt(((4-1)^2) + ((3-(-2))^2)) which would give an estimation of 2.16356+8.75449 for a total approximation of 10.9095 . For people who just want to know how many units separate these points on a graph which is drawn with Cartesian coordinates it's 4 units horizontally and 3 vertically below y=1x=-2 or -4 units if y=0

Answer:

The population of interest to the researcher were the 250 first-year students that were monitored.

Step-by-step explanation:

In descriptive statistics, the portion of the cost of college education to be determined and has been selected for analysis is calle d "sample", the sample the researcher is interested in, considers the textbooks cost of first-year students, therefore the 250 first-year students is the researcher´s population of interest. This method involved the collection, presentation, and characterization.

Zach read a book for 10 minutes every weekend in the first month, 20 minutes in the second month, 40 minutes in the third month,

Lubov Fominskaja [6]

The answer is B.

This is because A is incorrect, Zach number of minutes didnt increase by an equal factor every month.

C and D are incorrect, Victoria's methods aren't exponential, but Zach's are.

So that leaves the only reasonable answer which is B.

What is the equation for the line?

Irina-Kira [14]

In order to find the equation of a line, you would have to use the equation y=mx+b.

First, find the slope: $\frac{y_{2}- y_{1} }{x_{2} x_{1} }$
There is (1,8) and (2, 16) so plug that in 16-8/2-1 = 8. That's your slope! (Or the m)

Next in order to find b, you have to plug in a point:
y=8x+b
Take (1,8) and plug it in for x and y:
8=8(1)+b
b=0
Your y intercept is 0 (which you can also see on the graph)

So your answer is: y=8x

5(3a-1)-2(3a-2)=3(a+2)+v

STatiana [176]

Answer:

<u>The answer is option C. 6a-7</u>

Step-by-step explanation:

Given that

5(3a-1)-2(3a-2)=3(a+2)+v

Solve for v

∴ v = 5(3a-1)-2(3a-2) - 3(a+2)

∴ v = 15a - 5 - 6a + 4 - 3a - 6

∴ v = 15a - 6a - 3a - 5 + 4 - 6

∴ v = 6a - 7

<u>So the answer is option C. 6a-7</u>
