The mean wages of 200 workers working in 3 shifts in a factory is 520.The average of 90 workers working in the first shift is Rs 500. The average of 60 workers working in the second shift is Rs 450.what is the average of workers working in the 3rd shift?
(with solution please)
Answers
Answer:
Rs 640
Step-by-step explanation:
Since, Mean wages of 200 workers = Rs 520
Therefore, total money earned by 200 workers = 200 × 520 = Rs 104000
Average of 90 workers in first shift = 500
Total earning of 90 workers = 90 × 500 = Rs 45000
Average earning of 60 workers in second shift = Rs 450
Total earning of these workers = 60 × 450 = Rs 27000
Remaining number of workers in 3rd shift = 200 - (90 + 60) = 50
Let the average earning of 50 workers in 3rd shift = x
Total earning of these workers = Rs 50x
Now total earning of 200 workers = Total earnings of workers working in different shifts
104000 = 45000 + 27000 + 50x
50x = 104000 - 72000
x = [tex]\frac{32000}{50}[/tex]
x = 640
Therefore, average earnings of the workers working in 3rd shift is Rs 640.

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

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

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

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

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
