Answer: C
Step-by-step explanation: x represents the number of classes, not the cost of classes.
Answer:
The correct options are 2 and 4.
Step-by-step explanation:
From the given box plot it is clear that





We know that these number divides the data in four equal parts.



25% of the data values lies between 50 and 110. Therefore option 1 is incorrect.
Seventy-five percent of the data values lies between 20 and 50. Therefore option 2 is correct.
It is unlikely that there are any outliers. This statement is not true because the is a huge difference between third quartile and maximum value.
Therefore option 3 is incorrect.
The interquartile range is

Therefore option 4 is correct.
The range is
Range = Maximum-Minimum

Therefore option 5 is incorrect.
Answer:
7 and 5
Step-by-step explanation:
they have variables with them
I'm not real sure if this is right but I did my best
Easy
y=a(x-h)^2+k
vertex is (h,k)
we know that vertex is (4,0)
input that point for (h,k)
y=a(x-4)^2+0
y=a(x-4)^2
passes thorugh the point (6,1)
input that point to find a
1=a(6-4)^2
1=a(2)^2
1=a(4)
divide both sides by 4
1/4=a
thefor the equation is
y=(1/4)(x-4)^2
or
y=(1/4)x^2-2x+4
