Which expression can be simplified to find the slope of the line of best-fit in the scatterplot below?

1 answer:

6 0

$\frac{134-35}{16-4}$ is the correct answer and this expression can be simplified to find the slope of the line of best-fit in the scatterplot below by using the the slope equation : $\frac{Y_{2} - Y_{1}}{X_{2} - X_{1}}$ .

What is Slope of the Line?

The slope of the line is the measure of its steepness and direction. Without using a compass, determining the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or none at all.

Any two distinct points on a line can be used to calculate the slope of that line. The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points on a line. In this article, we will learn about the slope-finding method and its applications.

Patrick drives from p to q at an average speed of 40mph.

Bumek [7]

The distance in miles from P to Q is 12 miles

<h3>Distances and speed</h3>

Let the distance from P to Q be "d"

Since the formula for calculating speed is expressed as:

s =d/t

For the distance of P to Q

40 = d/t

d = 40t

If he drives back at an average speed of 45mph and 2 mintes less, then;

45 = d/t - 0.033

d = 45 (t - 0.033)

Equating both distances

40t = 45(t - 0.033)

40t = 45t - 1.485

-5t = -1.485
t = 0.297

Get the distance from P to Q:

d = 40(0.297)
d = 11.88 miles

Hence the distance in miles from P to Q is 12 miles

Margaret is playing a game with a standard deck of 52 cards which contains 4 jacks. the first player to select a jack gets to st

zepelin [54]

With a typical 52-card deck that has 4 jacks, Margaret is playing a game. The game is initiated by the first player to choose a jack. When choosing first, Margaret's probability of selecting Jack is 1/13.

The same will occur since probability will be determined using the formula necessary outcome divided by total outcome.

Here, the total number of cards in the deck (total outcome) equals 52.

Given that Margaret can select any of the four jacks, the necessary result (number of jacks) is 4.

Probability is 4/52, or 1 by 13, which is the required probability for the question.

The diagram below depicts the international flow of funds in the 1920s.

Arada [10]

Number 1 represents the reparation payments from Germany to France and Britain.

<h3>What is the flow of funds?</h3>

The flow of funds implies the movement of money from one person or entity to another. In the case of the international flow of funds, this occurs as money moves from one country to another.

<h3>What does number 1 represent?</h3>

Considering number 1 occurs from Germany to France and Britain, it likely represents reparation payments. This is because by the end of the First World War in 1918 Germany had to pay a lot of money to the countries affected by its war actions, which included France and Britain.

Therefore, money flowed from Germany to France and Britain as shown in the diagram.
