Answer:
width =5.5ft
length =18
Step-by-step explanation:
w=x
L=2x+7
area=w*L
99 = x(2x+7)



2x(x+9)-11(x+9)=0
(2x-11)(x+9)=0
2x-11=0
2x=11
x=11/2
x=5.5
L=2x+7=2*5.5+7=11+7=18
Answer: ![(-9, 16]](https://tex.z-dn.net/?f=%28-9%2C%2016%5D)
This is the interval from -9 to 16. Exclude -9 but include 16.
=====================================================
Work Shown:
The idea is to multiply all sides by 5, then add 1 to all sides





This converts to the interval notation ![(-9, 16]](https://tex.z-dn.net/?f=%28-9%2C%2016%5D)
note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
Answer:
You should perform x trials until you observe a success.
Step-by-step explanation:
By process of elimination:
A binomial experiment is a statistical experiment that must meet certain requirements:
Each outcome is either a success (P) or a failure (Q).
All trials are independent.
There are a fixed number of "n" trials.
The probability of success, p, is the same for each trial.
