Which of the following functions has the function rule y= x +4
Answer:
Where are the following functions at?
Step-by-step explanation:
Answer:
what is the following
Step-by-step explanation:
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.

a lot measuring 240 ft by 400 ft is selling for $400 a front foot. what is the price
The price of the given 240 ft by 400 ft for selling $400 will be $96000.
What is the selling price of any item?The selling price is also known as the list price, which is the price that a seller tells of good to the buyer while selling price is the price that the seller actually gets from the buyer after a deal. Sometimes, the selling price is different than the marked price. However, sometimes the selling price and the marked price could be related also. A fixed price shop, meaning that the shopper that does not have any kind of discount.
Given that the lot measuring 240 ft by 400 ft is selling for $400 a front foot so 2400 × 400 = 96000.
Hence, $96000 will be the price.

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

on a map with a scale 1: 25000,the area of a lake is 33.6 square centimeters. calculate the actual area of the lake, giving your answer in square kilometers
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.
