Answer:
There is a positive correlation in the data set.
General Formulas and Concepts:
<u>Statistics - Scatterplots</u>
- Positive Correlation - an upwards trend in the data set
- Negative Correlation - a downwards trend in the data set
- No Correlation - an undeterminable correlation in the data set
Step-by-step explanation:
According the data set on the graph, we can see that if we draw a line of best fit, the overall data would be <em>increasing</em>. Therefore, we would have a <em>positive</em> correlation.
Answer:
True False False in that order
Step-by-step explanation:
Answer:
The slope of the line is 5.
The point slope form of the line is y=5x+6.
Step-by-step explanation:
We can find the slope using this formula:
5
The slope of the line is 5.
To find point slope form, we use the equation y=mx+b where m is the slope and b is the y-intercept.
The y-intercept of this slope is 6 and the slope is 5 so we get, y=5x+6
What will the radius of your cake be?
This is a problem of geometry. Given that the cake is circular, the greater the cake the greater the radius of it. So, as shown in the figure 1, the radius will be the distance from the center to any extreme point of the circle.
How many slices will you be able to cut?
The total area of a circle is given by:
We need to fin how many slices will be cut, so let's calculate the area of the circular sector which can be obtained simply applying rule of three, so:
Let's name n the number of slices, if we divide the total area by n this result, each area must equal, then:
Finally, we will be able to cut:
Slices
