Answer:
The probability that it will take fewer than six customer contacts to clear the inventory is 0.8%.
Step-by-step explanation:
We have a probability of making an individual sale of p=0.15.
We have 4 units, so the probability of clearing the inventory with n clients can be calculated as:
As we see in the equation, n has to be equal or big than 4.
In this problem we have to calculate the probability that less than 6 clients are needed to sell the 4 units.
This probability can be calculated adding the probability from n=4 to n=6:
Answer:
6,8,
Step-by-step explanation:
X = 2 + 4y....with x being the larger number and y being the smaller number
OR
y = 2 + 4x....with y being the larger number and x being the smaller number
Answer:
x=-1
Step-by-step explanation:
-4x-6-1+x^2-5+3
-3x^2-9=0
-3x^2=9
√-3x^2=√9
-3x=3
x=-1
Let's see.
4x/5 + 4/3 = 2x
First we have to make each denominator the same, so I'll multiply 4x/5 by 3/3, 4/3 by 5/5, and 2x by 15/15
Now we have 12x/15 + 20/15 = 30x/15
With everything in the same denominator we can solve the new equation of
12x + 20 = 30x
20 = 18x
10 = 9x
X= 10/9
