If the perimeter is 200 ft and the area is 2100 square feet...
P = 2l + 2w
A = l * w
The dimensions would be 30 ft by 70 ft.
Answer:
Part 1) The y-intercept is the point 
Part 2) The x-intercepts are the points 
Step-by-step explanation:
we have

This is a vertical parabola open upward
step 1
Find the y-intercept
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0


The y-intercept is the point (0,-3)
step 2
Find the x-intercepts
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0

solve for x
Adds 3 both sides


take square root both sides

so
The x-intercepts are the points 
Answer:
P (T) = 1/4
P ( T | F ) = 1/2 = P(F)
The events are not independent.
Step-by-step explanation:
Let F the event of picking the white ball first
P (F)= 1/2 ( picking the white ball first)
Let T be the event of getting the white ball twice,
P (T) = P( getting white ball) * P( getting white ball)
=( 1/2)*(1/2)
= 1/4
Here P(T∩F) = P(T) because the probability of getting the white balls is the same as probability of getting the white ball first both the times.
P ( T | F ) = P (T∩F)/ P(F)
= (1/4)/ (1/2)
= (1/2)
= 1/2 = P(F)
For the events to be independent the conditional probability P ( T | F ) must be equal to P(T).
Hence the events are not independent.
The proportional relationship is correctly graphed by graph vs.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the relationship that gives the montant M considering the number of items sold n is:
M = 3n.
Considering that the montant is the vertical axis, the graph is composed by points (n, 3n), that is, points (100, 300), (200, 600) and so on, hence the graph is graph vs.
