The experimental probability that the next student Estelle talks to will pick science is 1/2.
What is the experimental probability ?
Experimental probability is based on the result of an experiment that has been carried out multiples times
The experimental probability = number of students who liked science / total number of students surveyed
7/14 = 1/2

Answer:
y^2
Step-by-step explanation:
2y^3 + y^2 and 4y^4 + 2y^3
2y^3 + y^2......factor out y^2
y^2(2y + 1)
4y^4 + 2y^3...factor out y^2
y^2(4y^2 + 2y)
I would normally factor out 2y^3 out of this one...but u cant do it in the other one...the only common factor is gonna be y^2
the common factor is y^2 <===
Answer:
it is subtract 5
Step-by-step explanation:
If the length of rectangular school hall is 4 times the width and the perimeter be 55m, then the length is 22m and the width of the school hall be 5.5m.
Given that the length of rectangular school hall is 4 times the width.
We are required to find the length and breadth of the rectangle which has the length be 4 times the width.
Perimeter of rectangle is the sum of all the length and breadth of that rectangles.
Perimeter of rectangle is given as 55m
Perimeter=2(L+B)
let the width of rectangle be x.
Length of that rectangle be 4x.
According to question,
2(x+4x)=55
2*5x=55
10x=55
x=55/10
x=5.5 m
Width be 5.5 m.
Length of rectangle be 4*5.5=22m.
Hence if the length of rectangular school hall is 4 times the width then the length is 22m and the width of the school hall be 5.5m.
