Answer: The true statements are:-
There are about the same number of points above the x-axis as below it.
The points are randomly scattered with no clear pattern.
The number of points is equal to those in the scatter plot.
Explanation:
- A residual plot is a graph which shows that the residuals on the vertical axis and the independent variable on the horizontal axis.
Thus, the number of points is equal to those in the scatter plot and ame number of points above the x-axis as below it.
We know the points are randomly scattered across the plot, so that there is no relationship. Thus the points are randomly scattered with no clear pattern.
The answer is 246:157.
Step by Step:
Group A:
First, figure out 1/5 of the people in group A. ( 615/5 = 123 )
Find 2/5 ( the amount of people who lost ) ( 123*2 = 246 )
Group B:
They received the same amount of fuel cards, so you take 526 - 369 ( 3/5 of the last group, or the winners, which is the amount of cards they received ) = 157.
This is an area problem where the area of a circle is pi*r^2.
A quiche with a diameter of 12 has an area of pi*6^2 = 36pi
So if it can feed 6 people, then the serving size per person is 6pi per person.
A quiche with a diameter of 10 inches has an area of pi*5^2 = 25pi
If each person requires 6pi worth of quiche, then 25pi/6pi = 4 1/6 people.
So yes, it can serve 4 people.
24 divided by 8 is 3
so three students play the piano
