Answer:
a.(10,23)
b.(7,30)
e.(20,20)
Step-by-step explanation:
We are given that
x=Width of garden
y=Length of garden
According to question
Perimeter of rectangle=
Where x=Width of rectangle
y=Length of rectangle
Fencing used =
First we change inequality into equality
...(1)
...(2)
...(3)
Substitute x=0 in equation (3)
Substitute y=0 in equation (3)
Substitute x=0 and y=0 in equation (3)
It is true. Therefore, the shaded region below the line.
These are false equation .Therefore, the shaded region above the line.
Substitute x=5 in equation (3)
Substitute y=20 in equation (3)
Intersection point of equation (1) and (3) is (5,35) and intersect point of equation (2) and (3) is (20,20).
Now,
a.(10,23)
Substitute in
10>5 and 23>20
it satisfied all inequality.
Hence, it is a solution.
b.(7,30)
7>5
30>20
it satisfied all inequality.
Hence, it is a solution.
c.(18,25)
18>5
25>20
It does not satisfied third inequality
Hence, it is not a solution.
d.(8,35)
8>5
35>20
It does not satisfied third inequality
Hence, it is not a solution.
e.(20,20)
20>5
20=20
it satisfied all inequality.
Hence, it is a solution.
Binomial distribution can be used because the situation satisfies all the following conditions:1. Number of trials is known and remains constant (n)2. Each trial is Bernoulli (i.e. exactly two possible outcomes) (success/failure)3. Probability is known and remains constant throughout the trials (p)4. All trials are random and independent of the othersThe number of successes, x, is then given by
where
Here we're given
p=0.10 [ success = defective ]
n=3
(a) x=0
(b) x=2
(c) x ≥ 2
