The probability of the event of a wafer to be conforming and from lot A are as follows;
(a) P(A) ≈ 0.15541
(b) P(C) ≈ 0.84
(c) P(AC) ≈ 0.159
(d) P(A|C) ≈ 0.86
(e) P(C|A) ≈ 0.185
(f) E1 and E2 are independent events
How can the probability of an event be determined?Probability is given by the ratio of the number of required outcomes divided by the number of possible outcomes.
(a) The number of wafers from lot A = 79 + 13 = 92
79+13+157+43+260+40 = 592
Which gives;
The probability that the wafer is from lot A is therefore;
P(A) = 92/592 ≈ 0.15541(b) The conforming wafers = 79+157+260 = 496
Which gives;
P(C) = 496/592 ≈ 0.84(c) The conforming wafers in lot A are 79
Therefore;
The probability that the wafer is from lot A and conforming is therefore;
P(AC) = 79/496 ≈ 0.159(d) The probability that the wafer is conforming, given that it is from lot A is therefore;
P(A|C) = 79/92 ≈ 0.86
(e) The number of conforming wafers = 496
The probability that the wafer is from lot A given that it is conforming is therefore;
P(C|A) = 92/496 ≈ 0.185(f) Independent events are events such that the occurrence of one does not impact the probability of the other.
Given that the occurrence of E1 changes the probability of event E2 if the wafer is not replaced, the events are not independent events.

The required angle measure for the condition of the proportion of angles m∠RPS is 212.35°.
Given that,
m∠QPS = 88
m∠RPS = 5x+34
m∠QPR=8x+15
The measure of the angle m∠RPS is to be determined.
The angle can be defined as the one line inclined over another line. the measure of an angle is measured in two units of degrees and in radiants.
Here,
m∠QPR = m∠QPS + m∠RPS
8x + 15 = 88 + 5x + 34
8x - 5x = 88 + 34 - 15
3x = 107
x = 107 / 3
x = 35.67
Now,
m∠RPS = 5x+34 = 5 * 35.67 + 34 = 212.35°
Thus, the required angle measure for the condition of the proportion of angles m∠RPS is 212.35°.

You want to earn a total of $500 per week. Write and solve an equation to find out how many hours you must mow lawns to reach your goal. Let x= # of hours you mow lawns
Answers
The required equation for how many hours I have to work mowing lawns is f(x) = 10x + 200 and the required no. of hours is 30 hours.
What is a function ?A function can be thought of as an output for the given set of inputs.
According to the given question I work for 25 hours per week at the twist ice-cream shop and earn 8.00 dollars per hour.
∴ My total earning in a week will be (25×8) = 200 dollars.
But i want to earn 500 per week so need (500 - 200) = 300 dollars to reach my goal.
I also mow lawns in my neighbourhood for 10 dollars per hour.
∴ I need (300/10) = 30 hours to earn the amount i need which is 500 dollars.
An equation can be written as
f(x) = 10x + 200, where x is the no. of hours and f(x) = 500.
500 = 10x + 200.
10x = 500 - 200.
10x = 300.

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2
Part c: Is it possible for the company to make a profit of $15,000 ?
Answers
It is not possible for a company to make a profit of $15,000 with the revenue function as 100 x − 0.5 x² and the cost function as 60 x + 300.
We know that:
Profit = Revenue - Cost
Here, we have:
Revenue function = 100 x − 0.5 x²
Cost function = 60 x + 300
Profit = $ 15,000
Substituting the values, we get that:
100 x − 0.5 x² - 60 x - 300 = 15,000
40 x - 0.5 x² - 300 = 15,000
80 x - x² - 300 = 15,000
x² - 80 x + 300 + 15,000 = 0
x² - 80 x + 15,300 = 0
No, it is not possible for a company to make a profit of $15,000 as the above equation has no real solution.
Therefore, it is not possible for a company to make a profit of $15,000 with the revenue function as 100 x − 0.5 x² and the cost function as 60 x + 300.

x : y = 3 : 7
Then,
(x / y) = ( 3 / 7)
7x = 3y
(a) HCF of ( 9y + x) and ( 3y + 4x)

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given information:
A charity-event manager counted 54 ticket receipts the day after an event. The price for an adult ticket was $21, and the price for a student ticket was $5. The register confirms that $974.
Then
Let number of adult tickets = x
Let number of student tickets = y
And charity-event manager counted 54 ticket receipts
=> x + y = 54 -(1)
The price for an adult ticket was $21
price for a student ticket was $5
Total Amount = 21x + 5y
The register confirms that $974 was taken in.
=> 21x + 5y = 974 -(2)
The system of equations represents matters :
