For this problem, the working equation would be the one usedfor repeated trials probability.
Probability = n!/r!(n - r)! * p^r * q(n - r)
The probability of success is p. If we treat the error as success, then p = 0.10 and consequently q= 1 - p = 0.9. The n is the number of trials equal to 20. Then, the r i the number of successes.
a. n=20, p = 0.10, q = 0.9, r = 5
Probability = 20!/5!(20 - 5)! * 0.10^5 * 0.9^(20-5) = <em>0.0319</em>
b. n=20, p = 0.10, q = 0.9
For this part, you will have to add when r = 5, r=6, r=7 until r=20. That's a tedious process. So, it would be more reasonable to take r = 4, r = 3, r = 2, r = 1 and r = 0. Then, we will just find the difference.
For r=4,
P = 20!/4!(20 - 4)! * 0.10^4 * 0.9^(20-4) = 0.0898
For r=3,
P = 20!/3!(20 - 3)! * 0.10^3 * 0.9^(20-3) = 0.1901
For r=2,
P = 20!/2!(20 - 2)! * 0.10^2 * 0.9^(20-2) = 0.2852
For r=1,
P = 20!/1!(20 - 1)! * 0.10^1 * 0.9^(20-1) = 0.2702
For r=0,
P = 20!/0!(20 - 0)! * 0.10^0 * 0.9^(20-0) = 0.1216
Total P = 1 - (0.0898+0.1901+0.2852+0.2702+0.1216)
<em>Total P = 0.2332</em>
Answer:
D is the correct answer
Step-by-step explanation:
Given:
Unit base price: $435
Credit Card interest rate, i = 9.4% compounded monthly; i = 0.00783/month comp monthly
n = 1.5 years = 18 months
sales tax = 8.51%
First, determine the actual price of the unit by adding the sales tax to the base price of the unit:
$435 * (1 + 0.0851)
Actual price = $472.0185
So, the total amount paid by Brian should be higher than the actual price since he used his credit card. Use the formula from economics:
F = P (1+i)^n
F = $507.96
Therefore, the total amount paid by Brian is $507.96.

Diagram:
M------------O-------------N
................. ^ midpoint
Obviously if O is the *mid*point, then it is exactly halfway between M and N. That also means it has bisected the segment into two equal parts.
On one side you have MO (or OM, if you like)
On the other side you have ON.
In order for O to be the midpoint:
ON = OM
Hello :
an equation is :
y - 2 = -2(x-1).....(<span>a line parallel to the line y = -2x + 1 ' same slope : -2)
y = -2x+4</span>
The division ➗ ÷ sign will make the expression correct if you correct the question!
