Answer:
A²
Step-by-step explanation:
The prior probabilities for events A1, A2, and A3 are P(A1) = 0.50, P(A2) = 0.20, and P(A3) = 0.30. The conditional probabilities of event B given A1, A2, and A3 are P(B | A1) = 0.50, P(B | A2) = 0.40, and P(B | A3) = 0.20. (Assume that A1, A2, and A3 are mutually exclusive events whose union is the entire sample space.)
Required:
Compute P(B â© A1), P(B â© A2), and P(B â© A3).
Answer:
P( B∩ A₁ ) = 0.25
P( B∩ A₂ ) = 0.08
P( B∩ A₃ ) = 0.06
Step-by-step explanation:
As we know that
P( B∩ A₁ ) = P( B| A₁) × P(A₁)
P( B∩ A₂ ) = P( B| A₂) × P(A₂)
P( B∩ A₃ ) = P( B| A₃) × P(A₃)
As we have
P(A₁) = 0.50, P(A₂) = 0.20, and P(A₃) = 0.30.
P(B | A₁) = 0.50, P(B | A₂) = 0.40, and P(B | A₃) = 0.20
⇒P( B∩ A₁ ) = P( B| A₁) × P(A₁)
= 0.50(0.50)
= 0.25
⇒P( B∩ A₁ ) = 0.25
Now,
⇒P( B∩ A₂ ) = P( B| A₂) × P(A₂)
= 0.40(0.20)
= 0.08
⇒P( B∩ A₂ ) = 0.08
Now,
⇒P( B∩ A₃ ) = P( B| A₃) × P(A₃)
= 0.20(0.30)
= 0.06
⇒P( B∩ A₃ ) = 0.06
∴ we get
P( B∩ A₁ ) = 0.25
P( B∩ A₂ ) = 0.08
P( B∩ A₃ ) = 0.06
Area of the Composite Figure:
in 2
llin
4in
15 in
Answer:
58.3 in^2
Step-by-step explanation:
The shape is made of a rectangle, a triangle and a semi-circle. We can find the area of each section and then add them together to get the area of the whole shape.
The area of a rectangle is length x width.
The length of the rectangle is 11 inches and the width is 4 inches
11 times 4 is 44
so the area of the rectangular section is 44 inches squared
To find the semi circle, I would find the area of a circle with an equal radius, and then divide that by 2.
The area of a circle is pi times the radius squared.
The radius here is 2 inches because it says diameter is 4 inches
2 squared is 4 and 4 times pi is ~12.6
So the area of the semi-circle section is ~6.3 inches squared
The area of a triangle is 1/2 base x height
Both the base and height of this triangle are 4 inches long (15-11=4)
so 1/2(4) times 4 is 8
so the area of the triangle section is 8 inches squared
Add them all together and you get 58.3 inches squared

IN YOUR ANSWER.
eb9th
m 12:00
Your answer:
Answer:
156 pages.
Step-by-step explanation:
Ophelia's reading speed is 104 pages / 2 hours = 52 pages/hour. So in 3 hours she will have read 3 * 52 = 156 pages.

Car repairs: Let be the event that a new car requires engine work under warranty and let be the event that the car requires transmission work under warranty. Suppose that ,P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.
Answer:
a) 0.11 = 11% probability that the car needs work on either the engine, the transmission, or both.
b) 0.9 = 90% probability that the car needs no work on the engine.
Step-by-step explanation:
P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
This means that:
Only engine: 0.1 - 0.01 = 0.09
Only transmission: 0.02 - 0.01 = 0.01
Both engine and transmission: 0.01
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
0.09 + 0.01 + 0.01 = 0.11
0.11 = 11% probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.
Probability of needing work on engine:
0.09 + 0.01 = 0.1
Not needing:
1 - 0.1 = 0.9
0.9 = 90% probability that the car needs no work on the engine.

Together, Rahman and Elissa have 120 DVDs. Rahman's collection has 5 times as many DVDs as Elissa's collection. Which
equation can be used to determine the number of DVDs in Elissa's collection?
Answer:
B
Step-by-step explanation:
rahman's collection represents the 5x and Elissa's represents the singluar x. Rahman has five times as many as Elissa, 5x is five timas as big as x. this means x=20. Rahman has 5x20=100 DVDs and Elissa has just 20.

the a
possible answers are 1/18
2/9
1/9
1/2
Answer:
1/18
Step-by-step explanation:
The spinner has 6 sections.
There are 2 vowels, A and U.
There is only one section with a K.
p(event) = (number of desired outcomes)/(total number of outcomes)
p(vowel) = 2/6 = 1/3
p(k) = 1/6
Each spin is an event. The two events are independent, so the probability of the two events is the product of the individual probabilities.
p(vowel, then K) = p(vowel) * p(k)
p(vowel, then K) = 1/3 * 1/6 = 1/18

Find Linear Functions using Graphs: y = 6x - 4
Answer:
[tex]x=\frac{y+4}{6}[/tex]
Step-by-step explanation:
y=6x−4
Swap sides so that all variable terms are on the left hand side.
6x−4=y
Add 4 to both sides.
6x=y+4
Divide both sides by 6.
[tex]\frac{6x}{6}=\frac{y+4}{6}[/tex]
Dividing by 6 undoes the multiplication by 6.
[tex]x=\frac{y+4}{6}[/tex]
Divide y+4 by 6.
[tex]x=\frac{y}{6} +\frac{2}{3}[/tex]
ANSWER:
x=1/6y + 2/3
y= 6x - 4
