A person with type O blood can donate red blood cells to anybody because type O blood is the universal donor blood type. About 4

4% of the US population has type O blood. You are asked to design a simulation to determine the probability that at least 3 of 10 people will have type O blood.
Part A: Conduct five trials using the following table of random digits:

96299 07196 98642 20639 23185 56282 69929 14125 38872 94168

03272 41230 81739 74797 70406 18564 69273 72532 78340 36699
46376 58596 14365 63685 56555 42974 72944 96463 63530 24152
47352 04266 74017 79319 70170 96572 08523 56025 89077 57678
(5 points)

Answer: (b) 0.8

Step-by-step explanation:

\\Assign 00 - 43 to people will have type O blood and assign 44 - 99 to people will not  have type O blood

\\Trial 1 :

\\Blood group O - 4

\\Not Blood group O - 6

\\Trial 2 :

\\Blood group O - 4

\\Not Blood group - 6

\\Trial 3:

\\ Blood group - 5

\\Not Blood group - 5

\\Trial 4:

\\Blood group: 5

\\Not Blood group - 5

\\Trials 5 :

\\Blood group - 2

\\Not Blood group - 8

\\(b) Out of the 5 trials it was in the fifth trial that the number of blood group O is not up to 3,so,  the probability that at LEAST 3 of 10 people will have type O blood?

\\= 4/5

\\= 0.8

Which pair of funtions is not a pair of inverse functions? please help!!
antiseptic1488 [7]

Answer:

f(x)=\frac{x}{x+20} , g(x)=\frac{20x}{x-1}

Step-by-step explanation:

we know that

To find the inverse of a function, exchange variables x for y and y for x. Then clear the y-variable to get the inverse function.

we will proceed to verify each case to determine the solution of the problem

<u>case A)</u> f(x)=\frac{x+1}{6} , g(x)=6x-1

Find the inverse of f(x)

Let

y=f(x)

Exchange variables x for y and y for x

x=\frac{y+1}{6}

Isolate the variable y

6x=y+1

y=6x-1

Let

f^{-1}(x)=y

f^{-1}(x)=6x-1

therefore

f(x) and g(x) are inverse functions

<u>case B)</u> f(x)=\frac{x-4}{19} , g(x)=19x+4

Find the inverse of f(x)

Let

y=f(x)

Exchange variables x for y and y for x

x=\frac{y-4}{19}

Isolate the variable y

19x=y-4

y=19x+4

Let

f^{-1}(x)=y

f^{-1}(x)=19x+4

therefore

f(x) and g(x) are inverse functions

<u>case C)</u> f(x)=x^{5}, g(x)=\sqrt[5]{x}

Find the inverse of f(x)

Let

y=f(x)

Exchange variables x for y and y for x

x=y^{5}

Isolate the variable y

fifth root both members

y=\sqrt[5]{x}

Let

f^{-1}(x)=y

f^{-1}(x)=\sqrt[5]{x}

therefore

f(x) and g(x) are inverse functions

<u>case D)</u> f(x)=\frac{x}{x+20} , g(x)=\frac{20x}{x-1}

Find the inverse of f(x)

Let

y=f(x)

Exchange variables x for y and y for x

x=\frac{y}{y+20}

Isolate the variable y

x(y+20)=y

xy+20x=y

y-xy=20x

y(1-x)=20x

y=20x/(1-x)

Let

f^{-1}(x)=y

f^{-1}(x)=20x/(1-x)

\frac{20x}{1-x}\neq \frac{20x}{x-1}

therefore

f(x) and g(x) is not a pair of inverse functions

Explanation:

As a road of

4
