Which characteristics describe the scatterplot?

1 answer:

6 0

Like other graphs, they use an x axis, and a y axis. It shows how one variable can affect another, hence the x and y (independent variable versus the dependent variable). With scatter plots you can use it to find a line of best fit that shows an average correlation relationship of the data. Scatter plots also allow you to find any outliers (those little dots that aren't in a pattern, correlation, or area with the majority of other points). It usually shows a relationship between TWO sets of data. :) :>

Question 1: Find the equation of the line through point (5,4) and perpendicular to y=−43x−2. Use a forward slash (i.e. "/") for

Mariulka [41]

Answer:

Question 1: y = 3/4x + 1/4.

Question 2: y = 6/5x + 7/5.

Step-by-step explanation:

Question 1: A line perpendicular to another line would have a slope that is the negative reciprocal of the other line. If the slope of the first line is -4/3, the slope of a line perpendicular to the first would have a slope of 3/4.

Since the line goes through (5, 4), we can just put the points into the equation, y = 3/4x + b.

4 = 3/4(5) + b

b + 15/4 = 4

b = 16/4 - 15/4

b = 1/4

So, the equation of the line is y = 3/4x + 1/4.

Question 2: 5x + 6y = -6

6y = -5x - 6

y = -5/6x - 1

As stated before, a line perpendicular to another will have a slope that is the negative reciprocal of the other. So, the slope of the other line is 6/5.

The line goes through (-2, -1), so we can put the points into the equation, y = 6/5x + b.

-1 = 6/5(-2) + b

b - 12/5 = -5/5

b = -5/5 + 12/5

b = 7/5

So, the equation of the line is y = 6/5x + 7/5.

Hope this helps!

A department store sells a pair of shoes with an 87% markup. If the store-bought the pair of shoes for $55.25, what is the selli

olga_2 [115]

Answer: $103
Explanation:
Stores will markup an item to make a profit so this question is asking how much they will be selling the shoes to the customer.
To solve this problem we will start by multiplying the price the store payed for (55.25) by the percentage in decimal form (.87)
55.25•0.87=48.0675

We then add the markup to the price payed for the shoes.
55.25+48.0675=103.3175

When rounding to the nearest dollar we look at the digit in the tens place (3) and since 3 is < 5 we round the final price to $103

Answer:

The average speed is 24 km/h less than the top speed of the lorry.

Step-by-step explanation:

The top speed of the lorry is the highest speed reached during transit, while its average speed is the mean speed attained

Given:.

Top speed of the lorry = 90 km/h

Average speed of the lorry = 66 km/h

Then,

The difference between the speed reached = top speed - average speed

= 90 - 66

= 24 km/h

Therefore, the average speed is 24 km/h less than the top speed of the lorry.

Find slope x-intercept=5,y-intercept=3

shutvik [7]

Intercepts occur when a line crosses the x-axis or the y-axis. When the line crosses the x-axis, then y = 0 and x = 3. ... The intercept points are (0, 4) and (3, 0 ). So the y-intercept is 4 and the x intercept is 3 and the sum is 7.

How many ounces of pure cranberry juice and how many ounces of a citrus fruit drink containing 14% fruit juice should be mixed t

OlgaM077 [116]

Let cranberry juice be x.
Let citrus fruit juice be y.

x + y = 630
x + 0.1y = 630*0.23

Solving this yields,

x = 91
y = 539

Therefore, you need 91 oz of pure cranberry juice and 539 oz of fruit juice.

Hope this helps.:)
