A company produces only one type of light bulbs. The light bulbs are being manufactured two factories: Factory A and Factory B. Factory A produces 10, 000 bulbs every year, while Factory B produces 2, 000. Also 2% of bulbs from Factory A are defective while 1% of bulbs from Factory B are. After production all bulbs are brought to the same facility and shipped to retail stores.

Required:
a. What is the probability that a bulb bought from a store is defective?
b. Given that the bulb is defective, what is the probability that it was produced by Factory A?
c. Given that the bulb is functional, what is the probability that it was produced by Factory A?

Answers

Answer 1

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

Given values:

[tex]P(\frac{D}{A})=0.02 \\\\P(\frac{D}{B})=0.01\\\\P(A)=\frac{10,000}{10,000+2000} =\frac{10}{12} =\frac{5}{6} \\\\P(B)=\frac{1}{6}\\\\[/tex]

For point a:

[tex]P(D) =p(D\cap A) +P(D \cap B)\\\\[/tex]

         [tex]=P(\frac{D}{A}) \times P(A) + P(\frac{D}{B}) \times P(B)\\\\=0.02 \times \frac{5}{6} + 0.01 \times \frac{1}{6}\\\\=\frac{0.1}{6} + \frac{0.01}{6}\\\\=\frac{0.1+0.01}{6} \\\\=\frac{0.11}{6} \\\\=\frac{11}{600} \\\\=0.0183[/tex]

For point b:

[tex]P(\frac{A}{D})= \frac{P(\frac{D}{A}) \times P(A)}{P(D)}\\\\[/tex]

         [tex]= \frac{0.02 \times \frac{5}{6}}{\frac{11}{600}}\\\\= \frac{0.02 \times \frac{5}{6}}{0.0183333333}\\\\= \frac{0.02 \times 0.833333333}{0.0183333333}\\\\= \frac{0.0166666667}{0.018}\\\\=0.9090 \approx 0.0991[/tex]

For point c:

[tex]P(\frac{A}{D^C})=\frac{P(\frac{D^c}{A}) \times P(A)}{P(D^c)}\\\\[/tex]

           [tex]= \frac{1-0.02 \times \frac{5}{6}}{1- \frac{11}{600}}\\\\= \frac{0.98 \times \frac{5}{6}}{0.98}\\\\=\frac{5}{6}\\\\=0.833[/tex]

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 4,335 square feet. The width of the basement is
3/5 its length. What is the length of Louis's basement? The length is blank feet.

Answers

Answer:

The length of Louis's basement is 85 feet.

Step-by-step explanation:

The area of the basement, A = 4,335 square feet

The width of the basement is  3/5 its length.

Let length be l.

Width = (3/5)l

The area of the basement is given by :

[tex]A=l\times b\\\\4,335 =l\times \dfrac{3}{5}l\\\\4,335 =\dfrac{3}{5}l^2\\\\l^2=\dfrac{4,335 \times 5}{3}\\\\l=\sqrt{\dfrac{4335\times5}{3}}\\\\l=85\ ft[/tex]

So, the length of Louis's basement is 85 feet.

The seventh-grade class is putting on a variety show to raise money. It costs $150 to rent the auditorium that they are going to use. If they charge $5 per ticket, how many tickets do they need to see in order to raise at least $750?

Answers

Answer:

180 tickets

Step-by-step explanation:

750 + 150 = 900 they will have to make

900/5 = 180 tickets

To raise at least $750, the seventh-grade class needs to sell a minimum of 180 tickets, priced at $5 each, to cover the fundraising goal and the $150 auditorium rental cost.

Given that,

Seventh-grade class is putting on a variety show to raise money.

The auditorium rental cost is $150.

Each ticket is priced at $5.

The goal is to raise at least $750.

Denote the number of tickets they need to sell as "x".

The revenue generated from ticket sales can be calculated by multiplying the number of tickets sold (x) by the ticket price ($5),

Which gives us 5x dollars.

Now since,

Total revenue from ticket sales - Auditorium rental cost ≥ Fundraising goal

Therefore,

5x - 150 ≥ 750

Add 150 to both sides:

5x ≥ 900

Divide both sides by 5 to solve for x:

x ≥ 180

Since the seventh-grade class cannot sell a fractional number of tickets,

Hence,

They need to sell at least 180 tickets to raise at least $750 and cover the auditorium rental cost.

The point (4, 3) is on the graph of this exponential model.

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can use the given information to form two equations with two unknowns (a and b) and solve for them.

From the first data point (2, 3 km):

y = a b^x

3 = a b^2

From the second data point (3, 9 km):

y = a b^x

9 = a b^3

Dividing the second equation by the first equation:

9/3 = (a b³) / (a b²)

3 = b

Substituting b = 3 into the first equation:

3 = a x 3²

a = 1/9

So the exponential model is y = (1/9) x 3^x.

To find another point on the graph of this exponential model, we can choose a value for x and calculate y.

Let's try x = 4:

y = (1/9) x 3^4

y = 1 x 3/3 x 3/3 x 3/3 x 3/9

y = 3

Therefore,

The point (4, 3) is on the graph of this exponential model.

What is the probability of rolling a six on a fair die?

Answers

Answer: 1/6

Step-by-step explanation: To find the probability of rolling a six,

let's use our ratio for the probability of an event.

number of favorable outcomes / total number of outcomes

Since only one side of a die has a six on on it, the number of favorable

outcomes for rolling a six is 1 and since there are six sides to a die and it's

equally likely that the die will landy on any of these sides, the total number

of outcomes is 6.

So the probability of rolling a six is 1/6.
