Answer:
Step-by-step explanation:
probability of selecting a girl from students is
probability of girl wearing sneaker from girls is or
hence, probability of selecting a girl wearing a sneaker will be,
⇒ probability = probability of delecting a girl from students × probability of girl wearing sneakers from girls
⇒ probability =
⇒ probability =
Answer:
a) 0.1829
b) 0.6823
c) 0.0413
Step-by-step explanation:
We are given the following information:
We treat adult having little confidence in the newspaper as a success.
P(Adult have little confidence) = 62% = 0.62
Then the number of adults follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 10
a) exactly 5
0.1829 is the probability that exactly 5 out of 10 U.S.adults have very little confidence in newspapers.
b) atleast six
0.6823 is the probability that atleast 6 out of 10 U.S. adults have very little confidence in newspapers.
c) less than four
0.0413 is the probability that less than 4 out of 10 U.S. adults have very little confidence in newspapers.
Answer:
No. James didn't have enough ticket takers to process the average number of patrons hat usually attend the events.
He need to hire 2 more ticket taker (i.e 20 ticket takers) in order to process the average number of patrons hat usually attend the events.
Step-by-step explanation:
Given:
Average amount of patron per event= 7000
Each ticket taker can process = 350
Number of ticket takers hired = 18
We need to find the whether he hire enough to process the average number of patrons that usually attend the events.
Solution:
We will find the Average amount of patron ticket takers can process.
Now we can say that
Average amount of patron ticket takers can process is equal to Each ticket taker can process multiplied by Number of ticket takers hired.
framing in equation form we get;
Average amount of patron ticket takers can process =
Hence With the required hires James cannot fully process the patrons usually attending the event.
To find how many ticket takers required we will divide average number of patrons with Each ticket taker can process.
framing in equation form we get;
ticket takers required =
hence In order t process the the average number of patrons that usually attend the events James will require 20 ticket takers.
Answer:
For First Solution:
is the solution of equation y''-y=0.
For 2nd Solution:
is the solution of equation y''-y=0.
Step-by-step explanation:
For First Solution:
In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.
First order derivative:
2nd order Derivative:
Put Them in equation y''-y=0
e^t-e^t=0
0=0
Hence is the solution of equation y''-y=0.
For 2nd Solution:
In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.
First order derivative:
2nd order Derivative:
Put Them in equation y''-y=0
cosht-cosht=0
0=0
Hence is the solution of equation y''-y=0.
