Applications of Probability Project: Zombie Apocalypse Adapted from "Are You Positive?" Learning Task in the Georgia Frameworks Zombies are on the loose! A group of researchers wants to be able to detect those who have contracted the zombie virus before they turn into zombies. Those who test positive will be quarantined for two weeks. If they show no signs of being a zombie, they will be freed. They have developed a simple test where they swab the person's ear (mouth would be too dangerous). They gathered 200 people of which 50 were known to be have the zombie virus. Of those who had the virus, 48 tested positive. Of those who did not have the virus, 135 tested negative 1. Based on the data presented above, do you think the test for zombieism is effective at detecting future zombies. Why or why not?
Answer:
Yes, it is a very effective test, having almost a 100% detection rate you wouldn't need much to improve upon except testing multiple times.
15) A store is having a sale during which all outdoor furniture is 45% off the original price, p. If
the post-sale price of an outdoor furniture set can be calculated using the expression p
0.45p, which expression also represents the price?
Answer and explanation:
Given that there is 45% off original price of outdoor furniture and price is represented by p
Discount on original price of outdoor furniture = 45% of p=0.45×p=0.45p
Therefore post sale price(after discount) of outdoor furniture can be represented by (1-0.45)p=0.55p

The National Household Travel Survey gathers data on the time of day when people begin a trip in their car or other vehicle. Choose a trip at random and record the time at which the trip started. What probability should replace the "?" in the table?
Time of Day 10PM- 12:59AM 1AM- 5:50AM 6AM- 8:59AM 9AM- 12:59PM 1PM- 3:59PM 4PM- 6:59PM 7PM- 9:59PM
Probability 0.004 0.033 0.144 0.234 0.208 ? 0.123
a. 0.964
b. 0.379
c. 0.752
d. 0.218
Answer:
A probability of 0.254 should replace the "?" in the table
Step-by-step explanation:
We have the probabilities for the time of the day when each person begins a trip, during a 24-hour period.
The sum of these probabilities has to be 100% = 1.
The probabilities are of: 0.004, 0.033, 0.144, 0.234, 0.208, ?, 0.123
Since their sum has to be 1, we can find ?. So
0.004 + 0.033 + 0.144 + 0.234 + 0.208 + ? + 0.123 = 1
0.746 + ? = 1
? = 1 - 0.746
? = 0.254
A probability of 0.254 should replace the "?" in the table

Answer:
D:21
Step-by-step explanation:
Use the vertical angles equation.
4x + 13 = 5x - 8
Subtract 4x from 5x.
5x - 4x = x
13 = x - 8
Add 8 on both dies.
13 + 8 = 21
x = 21

Answer:
x=18.5 y=14.2
Step-by-step explanation:
The unmarked angle for the top/x triangle is 109 (all angles add up to 180, 180-50-21=109)
Use cosine rule:
(a/sina)=(b/sinb)
(x/sin109)=(15/sin50)
(x/sin109)=19.58110934
x=18.51430261
The top-most angle of the bottom/y triangle is 71 (angles on a straight line are 180, 180-109=71)
The righthand angle of the bottom/y triangle is 19 (angles in a triangle add to 180, 180-71-90=19)
Use cosine rule again:
(a/sina)=(b/sinb)
(y/sin71)=(15/sin90)
y/sin71=15
y=14.18277863
A learning experiment requires a rat to run a maze (a network of pathways) until it locates one of three possible exits. Exit 1 presents a reward of food, but exits 2 and 3 do not. (If the rat eventually selects exit 1 almost every time, learning may have taken place.) Let Yi denote the number of times exit i is chosen in successive runnings. For the following, assume that the rat chooses an exit at random on each run.

Find the probability that n = 6 runs result in Y1=3,Y2=1, and Y3=2
=0.823
Step-by-step explanation:
Multinomial distribution
p(y1;y2,y3…..yk) = (n!/y1!,y2!,y3!…y4!) x p1^y1 x p2^y2 x p3^y3 x pk^yk)
The rat chooses of the three exists at random:
p = 1/3
p(3,2,1) = 6! / 3! 1! 2! (1/3)^3 (1/3)^1 (1/3)^2
=20/243
=0.823

Which equation has no solution?

B. -4(1/2x + 2) = -2x - 8 + 4x
C. 7(x + 2) - 3x = 2/3 (6x + 3)
D. -2x + 5 - 3x + 12 = -5(x - 3) + 2
Answer:
C. 7(x + 2) - 3x = 2/3 (6x + 3)
Step-by-step explanation:
ANSWER FROM PLATO
When solving an equation, if the variable terms cancel out leaving different numbers on each side of the equal sign, then the equation has no solution.
Consider the following equation:
7(x + 2) - 3x = 2/3 (6x + 3)
7x + 14 - 3x = 4x + 2
4x + 14 = 4x + 2
14 = 2
Therefore, the equation has no solution.

Step-by-step explanation:
There are 90 passengers on a commuter flight from SFO to LAX, of whom 27 are traveling on business. In a random sample of five passengers, use the binomial model to find the approximate hypergeometric probability that there is at least one business passenger.
Answer:
0.8401 = 84.01% probability that there is at least one business passenger.
Step-by-step explanation:
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
In this question:
Samples of 5, so [tex]n = 5[/tex]
90 passengers, so [tex]N = 90[/tex]
27 traveling on businnes, so [tex]k = 27[/tex]
Probability that there is at least one business passenger.
Either none are on business, or at least one is. The sum of these probabilities is 100% = 1.
Probability of none on business:
[tex]P(X = 0) = \frac{C_{27,0}*C_{63,5}}{C_{90,5}} = 0.1599[/tex]
Probability of at least one business passenger:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1599 = 0.8401[/tex]
0.8401 = 84.01% probability that there is at least one business passenger.
Factor.
