Given :
On a map with a scale 1: 25000 .
The area of a lake is 33.6 square centimeters.
To Find :
The actual area of the lake.
Solution :
Let, actual area of lake is A.
So,
[tex]\dfrac{33.6}{A}=\dfrac{1}{25000}\\\\A = 840000\ cm^2[/tex]
We know , [tex]1 \ cm^2 = 10^{-10}\ km^2[/tex]
Area in km² is :
[tex]A = 840000\times 10^{-10}\ km^2\\\\A = 8.4 \times 10^{-5}\ km^2[/tex]
Hence, this is the required solution.

Brianna answers 5 questions for each chapter of a book she reads in English class.
Write an equation to represent the total number of questions, q,Brianna answers based on the number of chapters, C,
in the book she reads.
Enter your equation in the box.
Answer:
q=5c
Step-by-step explanation:
q is the total number of questions, so the other numbers/variables must be multiplied together to equal q.
c is the number of chapters read, so that must be multiplied by 5 (questions per chapter) in order to equal q.

The data shows an exponential function because the domain values are at regular intervals and the range values have a common factor 4.
What are exponential functions?Exponential functions are functions in which the independent or input variable x occurs as an exponent or power.
In the given data, the domain values x, are at regular intervals and the range values y, have a common factor of 4.
This shows an exponential growth in the range values.
Therefore, the data shows an exponential function because the domain values are at regular intervals and the range values have a common factor 4.

Twenty-five percent of the customers entering a grocery store between 5 P.M. and 7 P.M. use an express checkout. Consider five randomly selected customers, and let x denote the number among the five who use the express checkout. Find the probability that 2 of the customers use the express checkout.
Answer:
The required probability = 0.2637
Step-by-step explanation:
Let X represents the no of customers that uses the express checkout.
[tex]X \sim Binomial (n =5, p= 0.25)[/tex]
The probability mass function is given by:
[tex]P(X =x) = \dfrac{5!}{x!(5-x)!}(0.25)^x (1-0.25)^{5-x} \ \ ; for \ x =0,1,2,3,4,5[/tex]
To find:
[tex]P(X =2) = \dfrac{5!}{2!(5-2)!}(0.25)^2 (1-0.25)^{5-2} \ \[/tex]
[tex]P(X =2) = \dfrac{5!}{2!(3)!}(0.25)^2 (0.75)^{3} \ \[/tex]
[tex]P(X =2) = \dfrac{5\times 4 \times 3!}{2!(3)!}(0.25)^2 (0.75)^{3}[/tex]
[tex]P(X =2) = \dfrac{20}{2!}(0.25)^2 (0.75)^{3}[/tex]
P(X = 2) = 0.2637
Thus, the required probability = 0.2637
The prevalence of a certain disease is 0.09. A diagnostic test has been developed to test for the disease in question which returns a positive reading with probability 0.9 amongst those where it is known they have the disease and returns a negative result with probability 0.96 for those that are known not to have the disease. A person is suspected to have the disease, takes the test and the test comes back positive. What is the probability that they have the disease given that the test came back positive ?
Answer:
The probability that they have the disease given that the test came back positive is 0.6899.
Step-by-step explanation:
Let A represent the event that the prevalence of a certain disease is 0.09
Let D be the event in which those patients are tested who already have the disease then the probability of B
P (D) = 0.9
Let F be the event in which those patients are tested who do not have the disease then the probability of F
P (F) = 0.96
The tree diagram helps explain the events and their probabilities.
A 0.09 -----------0.9 (D)= P(D/A) (positive test)
⇅------------0.1 ( negative test)
⇅
1----- ⇅
⇅
⇅
B 0.91 ------------0.96 (F)= P(F/ B) (negative test)
----------------0.04 P (G/B) (positive test)
By Bayes Theorem
P (A/ D)= P (A). P(D/A)/ P (A). P(D/A)+P (B) P(G/ B)
P (A/ D)= 0.09 (0.9)/ 0.09 (0.9)+ (0.91)(0.04)
P (A/ D)= 0.081/ 0.081+0.0364
P (A/ D)= 0.081/ 0.1174
P (A/ D)= 0.6899
The probability that they have the disease given that the test came back positive is 0.6899.
