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
Answers
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

canning operation is designed to fill cans with 14.5 oz of ingredients, on average, with a standard deviation of 0.1 oz. Nine cans are selected at random from the process, and the weights of the nine cans averaged 14.52 oz with a standard deviation of 0.075 oz. The standard error of the sample mean is:
Answers
Answer:
SE = 0.025
Step-by-step explanation:
We are given;
Sample mean; x¯ = 14.52
Sample standard deviation; s = 0.075
Sample size; n = 9
Now,formula for standard error of sample mean is;
SE = s/√n
SE = 0.075/√9
SE = 0.075/3
SE = 0.025

Steve opens a bank account. The amount, in dollars, in the account x weeks after the account is opened can be modeled by function f. If Steve has $5,000 in the account 20 weeks after the account is opened, which TWO of the following must be true?
Answers
The missing options are:
[tex]A.\ f(20) =5,000[/tex]
[tex]B.\ f(5000) = 20[/tex]
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
D. In the xy plane, point (5,000,20) is on the graph y = f(x)
Answer:
[tex]A.\ f(20) =5,000[/tex]
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
Step-by-step explanation:
Given
Represent amount with y and weeks with x
So, we have:
x = 20 when y = 5000
Required
Select 2 correct options
A point on a graph can be illustrated using [tex](x,y)[/tex]
So, when x = 20 and y = 5000 ----- given
[tex](x,y)[/tex] implies that:
[tex](x,y) = (20,5000)[/tex]
We got [tex](20,5000)[/tex] by substituting 20 for x and 5000 for y
From the list of given options, the above represented of (x,y) is illustrated in option C
Represent (x,y) as a function, we have:
[tex]y = f(x)[/tex]
Substitute values for x and y
[tex]5000 = f(20)[/tex]
Reorder
[tex]f(20) = 5000[/tex]
The above is illustrated in option A
Hence, A and C answers the question
A store orders 22 boxes of light bulbs. Each box has 148 bulbs.
Which is the best estimate of the total number of bulbs the store orders?
Answers
Answer:
3,256bulbs
Step-by-step explanation:
From the question, we can see that;
Total number of boxes ordered = 22boxes
If each box contains 148 bulbs, then;
1 box = 148bulbs
To get the total bulbs we have we will say;
22boxes = x bulbs
solve this two expressions for x:
1box = 148bulbs
22boxes = x bulbs
Cross multiply
1×x = 22×148
x = 3256bulbs
Hence the best estimate of the total number of bulbs the store orders is 3,256bulbs

Pauline Romer has taken a $100000 mortgage loan on her house at an interest rate of 3 percent per year. If the mortgage calls for 20 equal annual payments, what is the amount of each payment?
Answers
Answer:
5000
Step-by-step explanation:
Using the mortgage interest principle, the amount of equal payment to be made ls $8000
Mortgage payment = $100000
Interest rate = 3%
The total amount to repayed can be calculated thus :
Mortgage payment × interest rate × timeNumber of annual payments = 20
Total repayment = 100000(1 + (0.03 × 20))
Total repayment = 100000 + 60000 = $160,000
Amount of each payment = $160000 / 20 = $8000
Therefore, the amount to be repayed annually is $8000
