Answer:
y = 1, 9.
Step-by-step explanation:
They are the y values of the points of intersection of the 2 parabolas.
y = 1, 9.
Let the width be x
The length would be 2x-5
So, 2(x+2x-5)=80
3x-5=40
3x=45
x=15.
So the width is 15 and the length would be 25.
Answer:
1. no
2. no
3. yes
4.yes
Step-by-step explanation:

The solutions of x are 1 and
Step-by-step explanation:
Given,quadratic equation is
[ here a =2, b= 3 and c= -5]
Either x =1 or,
A sample of size <em>n</em> taken from a normally distributed population with mean <em>µ</em> and standard deviation <em>σ</em> has a sample mean of <em>µ</em> and standard deviation of <em>σ</em>/√<em>n</em>.
So the sample mean would still be 180.1, while the sample standard deviation would be 100/√94 ≈ 10.31.
