Answer:
a) 11% probability that the first patient with heart failure that enters the emergency room has the conditions due to outside factors.
b) 0.0871 = 8.71% probability that third patient with heart failure that enters the emergency room is the first one due to outside factors.
c) The mean number of heart failure patients with the condition due to natural causes that enter the emergency room before the first patient with heart failure from outside factors is 9.09.
Step-by-step explanation:
We have these following probabilities:
89% probability that a patient has heart failure due to natural occurrences.
11% probability that a patient has heart failure due to outside factors.
A) What is the probability that the first patient with heart failure that enters the emergency room has the conditions due to outside factors?
We assume that causes of heart failure between individuals are independent, which means that the probabilities are the same for each patient. So:
11% probability that the first patient with heart failure that enters the emergency room has the conditions due to outside factors.
B) What is the probability that third patient with heart failure that enters the emergency room is the first one due to outside factors?
First two due to natural occurrences, each with 89% = 0.89 probability.
Third due to outside factors, with 11% = 0.11 probability. So
0.89*0.89*0.11 = 0.0871
0.0871 = 8.71% probability that third patient with heart failure that enters the emergency room is the first one due to outside factors.
C) What is the mean number of heart failure patients with the condition due to natural causes that enter the emergency room before the first patient with heart failure from outside factors?
11% with outside factors, so the mean number of patients before the first with outside factors is given by
m = 1/0.11 = 9.09
The mean number of heart failure patients with the condition due to natural causes that enter the emergency room before the first patient with heart failure from outside factors is 9.09.

Decrease 18000 by 6%
Answer:
16920
Step-by-step explanation:
6% of 18000 is 1080 so 18000-1080 is 16920
Answer:
16920
Step-by-step explanation:
18000-6% of 18000
=18000-6/100*18000
=18000-1080
=16920

An entrepreneur faces many bureaucratic and legal hurdles when starting a new business. The World Bank collects information about starting businesses throughout the world. They have determined the time, in days, to complete all of the procedures required to start a business. The data for business start time, in days, for a sample of 24 countries is given. Data Set
13 66 36 12 8 27 6 7 5 7 52 48
15 7 12 94 28 5 13 60 5 5 18 18
The total for the given data is 567 days.
Later, we realize that we had not included the data for the South American country of Suriname in the sample. The start time for Suriname is 694 days.
a) What is the mean of the sample data including the country of Suriname? Give your answer to two decimal place.
b) Find the median time to start a business for 24 countries in our data set:
c) Which measure do you prefer for describing the center of this distribution? Explain your answer.
d) Compute the quartiles (Q1, Q2, Q3), and find the IQR for these data. Are there outliers in the time to start a business data set? If so, identify and name any outliers.
e) Compute the standard deviation of time to start a business for 24 countries in the data set:
f) Which measure do you prefer for describing the spread of this distribution? Explain your answer.
g) Make a boxplot for these data and explain & describe the distribution using only the information in the boxplot.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data :
Rearranged data:
5, 5, 5, 5, 6, 7, 7, 7, 8, 12, 12, 13, 13, 15, 18, 18, 27, 28, 36, 48, 52, 60, 66, 94
Start time for Suriname = 694
Mean = ΣX / n
Mean = (567 + 694) / (24 + 1) = 1261 / 25 = 50.44
B.) median start Time for initial 24 values
0.5(n+1)th term
0.5(25) = 12.5th term
(13 + 13) / 2 = 13
C.) preferred measure of center for the distribution will be the median as it shapes well in the middle of the distribution. The mean is overestimated
d) Compute the quartiles (Q1, Q2, Q3), and find the IQR for these data. Are there outliers in the time to start a business data set? If so, identify and name any outliers.
Using calculator :
Lower quartile Q1 --> 7
Median Q2 --> 13
Upper quartile Q3 --> 42
IQR = (Q3 - Q1) = 42 - 7 = 35
OUTLIER:
Lower bound : Q1 - 1.5(IQR) ; 7 - 1.5(35) = - 45.5
Upper bound : Q3 + 1.5(IQR) = 42 + 1.5(35) = 94.5
Outlier : values below - 45.5 and above 94.5
Hence, Surimanes start time is the only Outlier.
e)
Standard deviation for 24 countries :
Standard deviation = sqrt[Σ(X - mean)^2 / (N - 1)]
Usibg calculator :
Standard deviation for the 24 countries is 23.83
f)
Standard deviation

*Ms.Wilson ate 1/4 of a pizza in 12 minutes.*
1. If the pizza has 8 slices, how many slices will she eat in 18 minutes?
2. What fraction of the pizza will she eat in 30 minutes?
Problem 1
Answer: 3 slices-------------------------------------
Explanation:
1/4 = 0.25
She eats 25% of a pizza in 12 minutes
We can form the ratio 0.25/12
This ratio is then set equal to x/18. The value of x represents what proportion of the pizza is eaten after 18 minutes.
Solve for x
0.25/12 = x/18
0.25*18 = 12x ..... cross multiply
4.5 = 12x
12x = 4.5
x = 4.5/12
x = 0.375
x = 375/1000
x = (125*3)/(125*8)
x = 3/8
She ate 3/8 of the whole pizza in 18 minutes.
There are 8 slices in a full pizza, so (3/8)*8 = 3 means that she ate 3 slices.
Or you could say "eating 3 slices out of 8 total means she ate 3/8 of the full pizza".
===================================================
Problem 2
Answer: 5/8-------------------------------------
Explanation:
We'll use the same idea as before. Though now we're setting 0.25/12 equal to x/30
Solving for x leads to...
0.25/12 = x/30
0.25*30 = 12x
7.5 = 12x
12x = 7.5
x = 7.5/12
x = 0.625
x = 625/1000
x = (125*5)/(125*8)
x = 5/8
She will eat 5/8 of the pizza in 30 minutes.

A system may become infected by some spyware through the internet or e-mail. Seventy percent of the time the spyware arrives via the internet, thirty percent of the time via e-mail. If it enters via the internet, the system detects it immediately with probability 0.6. If via e-mail, it is detected with probability 0.8. What percentage of times is this spyware detected
Answer:
This spyware is detected 66% of times.
Step-by-step explanation:
We have these following percentages:
Seventy percent of the time the spyware arrives via the internet, and in this case is detected 60% of the time.
Thirty percent of the time the spyware arrives via e-mail, and in this case is detected 80% of the time.
What percentage of times is this spyware detected
0.7*0.6 + 0.3*0.8 = 0.66
This spyware is detected 66% of times.
Roberto has $200 in spending moneyHe wants to buy some video games that cost $25.50 eachWrite solve an inequality to find the number games, that Roberto can buy Enter your answer in the box
x>24 or x<24
Answer:
Roberto can buy 7 videogames.
Step-by-step explanation:
Given that Roberto has $ 200 in spending money and he wants to buy some video games that cost $ 25.50 each, to determine the number of games he can buy, the following inequality must be resolved:
25.50X = 200
X = 200 / 25.50
X = 7.84
Thus, since the whole number is 7, with $ 200 you can buy 7 video games, and there will be $ 21.5 (200 - 178.5) left over.
India is the second most populous country in the world, with a population of over 1 billion people. Although the government has offered various incentives for population control, some argue that the birth rate, especially in rural India, is still too high to be sustainable. A demographer assumes the following probability distribution for the household size in India. Household Size Probability 1 0.05 2 0.09 3 0.12 4 0.24 5 0.25 6 0.12 7 0.07 8 0.06 a. What is the probability that there are less than 5 members in a household in India
Answer:
[tex]P(At\ least\ 5) = 0.50[/tex]
Step-by-step explanation:
Given:
[tex]\begin{array}{cc}{Size} & {Probability} & {1} & {0.05} & {2} & {0.09} \ \\ {3} & {0.12} & {4} & {0.24} & {5} & {0.25} & {6} & {0.12} & {7} & {0.07} & {8} & {0.06}\ \end{array}[/tex]
Required
Determine the probability that there are at least 5 members in a household
At least 5 means 5 to 8.
So, the probability is:
[tex]P(At\ least\ 5) = P(5) + P(6) + P(7) + P(8)[/tex]
[tex]P(At\ least\ 5) = 0.25 + 0.12 + 0.07 + 0.06[/tex]
[tex]P(At\ least\ 5) = 0.50[/tex]
The probability is 0.50
