Answer:
Gery will get 45 £,Eddy will get 135 £ and Bernie will get 270 £ of the total share.
Step-by-step explanation:
Given:
Bernie, Eddy and Gery share £450.
Bernie gets twice as much as Eddy.
Eddy gets three times as much as Gery.
So,
Let Gery gets 'x' share of the amount.
Then,
Eddy's share will be ''
and
Bernie's share will be
According to the question.
Total share summation of total share =
⇒
⇒
⇒
So Gery's share = 'x'
Eddy's share =
Bernie's share =
Gery will get 45 £,Eddy will get 135 £ and Bernie will get 270 £ of the total share.
Answer:
y = - (x - 1)²(x + 2)(x + 6)
Step-by-step explanation:
The roots from the graph are
x = - 6 , then factor is (x + 6)
x = - 2 , then factor is (x + 2)
x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then
y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier
To find a substitute any point on the graph into the equation
Using (0, - 3 ), then
- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )
- = a
Then
y = - (x - 1)²(x + 2)(x + 6)
Answer:
The probability that the sample will contain exactly 0 nonconforming units is P=0.25.
The probability that the sample will contain exactly 1 nonconforming units is P=0.51.
.
Step-by-step explanation:
We have a sample of size n=4, taken out of a lot of N=12 units, where K=3 are non-conforming units.
We can write the probability mass function as:
where k is the number of non-conforming units on the sample of n=4.
We can calculate the probability of getting no non-conforming units (k=0) as:
We can calculate the probability of getting one non-conforming units (k=1) as:
