The true statement about the residual plot is (a) The regression line is a good model because there is no pattern in the residuals.
<h3>How to interpret the residual plot?</h3>
For a residual plot to be considered a good model, the points on the plot must be at random and they must not follow a specific pattern
From the graph, we can see that the points are scattered
Hence, the true statement about the residual plot is (a)

Plz don't be mad if I'm wrong..... lol :/
Answer:
112
Step-by-step explanation:
Define the variables:
x = number of French students sent by the school
Write the equation:
x / 21 = 1 / 3
Solve:
x = 7
The school sent 7 French students and 21 German students, for a total of 28 students.
The other 3 schools also sent 28 students. So the total number of students sent is:
4 × 28 = 112
12-x(5-4k)=y
12-y=x(5-4k)
12-y/(5-4k)=x
<h3>hello!</h3>
In order to solve this equation, we need to take the square root of both sides (in order to get rid of the square and isolate x, because we are asked to determine the value(s) of x)
x²=36
√x²=√36
x=6
Is this the only solution?
<em>A negative times a negative is a </em><em>positive...</em>
-6 is another solution of this equation! :)
Hence, the answers are:-
