Answer:
The probability that the first subject to be a universal blood donor is the seventh person selected is 0.0511
Step-by-step explanation:
Let's start defining the random variable X.
X : ''The first success is on the xth trial''
X can be modeled as a geometric random variable with the following probability function :
Where 
is the probability of the random variable X to assumes the value ''x''.
The variable p is the success probability.
For this exercise, we define a success as someone randomly selected is a universal donor and that probability is 
We are looking for : 
The probability function is :
Step-by-step explanation:
240,000 = 24 x 10^4
24 followed by 4 zeros = 24 x 104
Just make the number of zeroes be the exponent for 10
24 = 24 x 10^0
240 = 24 x 10^1
2400 = 24 x 10^2
24000 = 24 x 10^3
240,000 = 24 x 10^4 miles
Answer:
b = 8/3 or b = -9/5
Step-by-step explanation:
Solve for b over the real numbers:
(5 b + 9) (8 - 3 b) = 0
Split into two equations:
8 - 3 b = 0 or 5 b + 9 = 0
Multiply both sides by -1:
3 b - 8 = 0 or 5 b + 9 = 0
Add 8 to both sides:
3 b = 8 or 5 b + 9 = 0
Divide both sides by 3:
b = 8/3 or 5 b + 9 = 0
Subtract 9 from both sides:
b = 8/3 or 5 b = -9
Divide both sides by 5:
Answer: b = 8/3 or b = -9/5
Both Maria and Edwin get the same price on the end.
$26.50*75%/100=$19.875
$19.875*10%/100+$19.875=$21.86
They are purchased copy of the book for $21.86 each.
Theay have $1.14 after purchasing both.
