The probability of two events A and B happening simultaneously is 0.17. The probability of only event A happening is 0.34. Find the probability of event B happening, if event A has already happened
Answer:
because is the probability is 0.17 and 0.34 is fair
You can use the multiplication rule of probability.
The probability of event B happening if event A has already happened is 0.5
What does general multiplication rule of probability says for 2 events A and B?[tex]P( A \: \rm and \: B) = P(A)P(B|A) = P(B)P(A|B)[/tex]
Since we've to find the probability of B given that A has already happened, we need [tex]P(B|A)[/tex]
Since the probability of both event A and event B happening simultaneously is 0.17, thus:
[tex]P(A \: \rm and \: B) = 0.17\\
[/tex]
Since the probability of only event A happening is 0.34, thus:
[tex]P(A) = 0.34[/tex]
Thus, from the multiplication rule, we have:
[tex]P(A \: \rm and \: B) = P(A)P(B|A)\\
0.17 = 0.34 \times P(B|A)\\\\
\dfrac{0.17}{0.34} = P(B|A)\\\\
P(B|A) = \dfrac{1}{2} = 0.5[/tex]
Thus, we have the probability of event B happening when A has already happened as 0.5

A study of 800 homeowners in a certain area showed that the average value of the homes was $82,000, and the standard deviation was $5000. How many of these homes have a value greater than $83,500.
Round to a whole number.
I got 62 it says that is wrong answer.
Answer:
400
Step-by-step explanation:
it says average which probably means 400
33.36% of these homes have a value greater than $83,500.
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x \ is\ raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
Given that μ = $82000, σ = $5000.
For x > 83500:
[tex]z=\frac{83500-82000}{5000} =0.43[/tex]
From the normal distribution table, P(x > 83500) = P(z > 0.43) = 1 - P(z < 0.43) = 1 - 0.6664 = 33.36%
33.36% of these homes have a value greater than $83,500.

One month Jenny rented 6 movies and 2 video games for a total of $30. The next month she rented 3 movies and 5 video games for a total of $36. Find the rental cost for each movie and each video game.
Answer: The rental cost for each movie is $3.25 and each video game is $5.25.
Step-by-step explanation:
Let x = rental cost for each movie
y = rental cost for each video game.
As per given , we have
6x+2y= 30 (i)
3x+5y = 36 (ii)
Multiply 2 on both sides of (ii)
6x+10y=72 (iii)
Eliminate (i) from (iii)
8y=42
⇒ y= 5.25
Put y=5.25 in (ii)
3x+5(5.25)=36
⇒ 3x+26.25 =36
⇒ 3x = 36-26.25
⇒ 3x =9.75
⇒ x = 3.25 [Divide both sides by 3]
Hence, the rental cost for each movie is $3.25 and each video game is $5.25.
Answer:
2.25 movie
5.25 video game

Whatever is in parentheses you do first. So 7 to the power of 6 is multiplying 7 by itself 6 times using the sum of the previous answer. You would get 117649. In other words, use a calculator. Now, you have (117649)^2. So just use a calculator and get 13481287201

i need help with these 9 questions they’re pretty simple
Answer:
1. n = 4
2. n = -29
3. n = -28
4. n = -48
5. n = -22
6. n = 97
7. n = 220
8. n = -18
9. n = 36
Step-by-step explanation:
1. -n = -4
Multiply both by -1 to get n = 4
2. 12 + n = -17
Subtract 12 from both sides of the equation to get n = -29
3. -n/14 = 2
Multiply by 14 on both sides of the equation to get -n = 28
Multiply -1 on both sides of the equation to get n = -28
4. -42 = n + 6
Subtract 6 from both sides of the equation to get -48 = n or n = -48
5. -4n = 88
Divide -4 on both sides of the equation to get n = -22
6. n + -3 = 94
Add 3 to both sides of the equation to get n = 97
7. 11 = -n/-20
Multiply by -20 on both sides of the equation to get -220 = -n or -n = -220
Multiply -1 on both sides of the equation to get n = 220
8. -108 = 6n
Divide by 6 on both sides of the equation to get -18 = n or n = -28
9. 67 = 31 + n
Subtract 31 from both sides of the equation to get 36 = n or n = 36

(6.4)
DE=3.2cm
Answer:
AD=BE
Step-by-step explanation:
Because AB and BC are equal, their lengths are also equal and also it is an Isosceles triangle. Therefore the midpoint of AB or the half of AB which is either AD or DE are equal. Vice versa for BC. So AD=BE
