Step-by-step explanation:
Top right = Quadrant I
Top left = Quadrant II
Bottom left = Quadrant III
Bottom right = Quadrant IV
I think you can figure it out from there.
Let the width be called x inches, so the length is x+9 inches (width is 9in shorter than length) and x>0
So the area = w*l = x(x+9)
=> x^2+9x=252
=> x^2+9x-252=0
=> x^2 - 12x + 21x - 252 = 0
=>x(x-12) + 21(x-12) = 0
=> (x-12)(x+21)=0
=> x = 12 or -21
but x>0
=> x = 12 in
=> width = 12 in
=> length = 12+9 = 21 inches

Answer:Use a calculator
Explanation:it’s easier
Given the information, we shall proceed as follows:
The given problem is a binomial problem.
n=10 and p=0.48
thus, the probability that the number who consider themselves baseball fans is:
a] exactly five
P(x=5)=10C5(0.48)^5(0.52)^5=0.244
b] at least 6
P(x>=6)=1-P(x<8)
=P(6)+P(7)+P(8)+P(9)+P(10)
=10C6(0.48)^6(0.52)^4+10C7(0.48)^7(0.52)^3+10C8(0.48)^8(0.52)^2+10C9(0.48)^9(0.52)^1+10C10(0.48)^10
=0.1878+0.0991+0.0343+0.0070+0.0007
=0.3289
The answer: 0.3289
c] Less than 6
P(x<6)=1-P(x>=6)
=1-0.3289
=0.6711
