Answer:
The probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition is 0.6049.
Step-by-step explanation:
We are given that it is believed that 3% of people actually have this predisposition. The test is 99% accurate if a person actually has a predisposition.
The test is 98% accurate if a person does not have a predisposition.
Let the probability that people actually have predisposition = P(PD) = 0.03
The probability that people do not have a predisposition = P(PD') = 1 - P(PD) = 1 - 0.03 = 0.97
Let A = event that the test is accurate
So, the probability that the test is accurate if a person actually has a predisposition = P(A/PD) = 0.99
The probability that the test is correct if a person actually has a predisposition = P(A/PD') = 1 - 0.98 = 0.02
Now, the probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition = P(PD/A)
We will use Bayes' theorem to calculate the above probability.
P(PD/A) = [tex]\frac{P(PD) \times P(A/PD)}{P(PD) \times P(A/PD) + P(PD') \times P(A/PD')}[/tex]
= [tex]\frac{0.03 \times 0.99}{0.03 \times 0.99+0.97 \times 0.02}[/tex]
= [tex]\frac{0.0297}{0.0491}[/tex] = 0.6049.

(-1, 2[tex]\frac{1}{2}[/tex])
(0, 2)
(1, 1[tex]\frac{1}{2}[/tex])
(2, 1)
Step-by-step explanation:
You just simply substitue the values given into the equation, and the answer worked out will be the value of y.
a = - [tex]\frac{1}{2}[/tex] × -2 + 2 = 1 + 2 = 3
b = - [tex]\frac{1}{2}[/tex] × -1 + 2 = [tex]\frac{1}{2}[/tex] + 2 = 2[tex]\frac{1}{2}[/tex]
c = -[tex]\frac{1}{2}[/tex] × 0 + 2 = 0 + 2 = 2
d = -[tex]\frac{1}{2}[/tex] × 1+ 2 = -[tex]\frac{1}{2}[/tex] + 2 = 1[tex]\frac{1}{2}[/tex]
e = -[tex]\frac{1}{2}[/tex] × 2+ 2 = -1 +2 = 1

assume f(x)=-2x+8 and g(x)=3x. what is the value of (g o f)(3)
Answer:
6
Step-by-step explanation:
(g o f)(3) = g(f(3))
We can find f(3) using its formula with x=3:
f(3) = -2·3 +8 = -6 +8 = 2
Now, we can find g(2) using its formula with x=2:
g(2) = 3·2 = 6
So, the composition value is ...
(g o f)(3) = 6

Roberto and Maria Santanos spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and
dryer would cost them a total of $774. How many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer?
HELP PLEASE!
Answer:
72 weeks
Step-by-step explanation:
If 1 week =$10.75 then $774 will be equal to $774×1 week=774 then divide by $10.75=72 weeks
It will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.
We have - Roberto and Maria Santana's who spend approximately $10.75 per week to wash and dry their family's clothes at a local coin laundry. A new washer and dryer would cost them a total of $774.
We have to determine in how many weeks will it take for the laundromat cost to equal the cost of a new washer and dryer.
If you are saving $5 every day, then in how many days you will save %100?You will save $100 in = [tex]\frac{100}{5}[/tex] = 20 days.
According to question, we have -
Cost of a Laundromat = $10.75/week
Total cost of a new washer and dryer = $774.
The number of weeks it will take for the laundromat cost to equal the cost of a new washer and dryer will be -
n(W) = [tex]\frac{774}{10.75}[/tex] = 72 weeks
Hence, it will take 72 weeks the laundromat cost to equal the cost of a new washer and dryer.

f(x) = 14 – 0.5x f(30)=
Answer: f(30) = -1
You would substitute every X with 30
Answer:
-1
Step-by-step explanation:
First, plug in 30 to your equation (f(x) = 14 - 0.5(30)
0.5 • 30 is 15, so subtract 15 from 14 and you get -1
1. f(x) = x2 + x and g(x) = 2x + 1
a. Evaluate f(g(3))
b. Evaluate g(f(3))
Answer:
f(g(3)) = 56
g(f(3)) = 25
Step-by-step explanation:
fog = f(2x+1)
f(2x+1) = (2x+1)^2 + 2x+1
(2x+1)^2 + 2x+1 = 4x^2+6x+2
f(g(x)) = 4x^2+6x+2
f(g(3)) = 4(3)^2+6(3)+2
f(g(3)) = 56
gof = g(x^2+x)
g(x^2+x) = 2(x^2+x)+1
2(x^2+x)+1 = 2x^2 + 2x + 1
g(f(x)) = 2x^2 + 2x + 1
g(f(3)) = 2(3)^2 + 2(3) + 1
g(f(3)) = 25
