The time to failure (in hours) of fans in a personal computer can be modeled by an exponential distribution with l=0.0003
a. What proportion of the fans will last at least 10,000 hours?
b. What proportion of the fans will last at most 7000 hours?
Answer: 0.0497870 ; 0.87754
Step-by-step explanation:
Given that :
λ = 0.0003
Defining a continuous distribution function :
F(x) = 1 - e^-λx = 1 - e^-0.0003x ; x ≥ 0
a. What proportion of the fans will last at least 10,000 hours?
P(x ≥ 10000) = e^-0.0003(10000) = 0.0497870
b. What proportion of the fans will last at most 7000 hours?
P(x ≥ 7000) = 1 - p(x ≤ 7000) = 1 - e^-0.0003(7000)
1 - 0.12245642825 = 0.87754

If (4,-3) is the midpoint of the line segment ST and the coordinates of S are (1,5), find the
coordinates of T.
Answer:
[tex](7,-11)[/tex]
Step-by-step explanation:
Given
[tex]S = (1,5)[/tex]
[tex]M = (4,-3)[/tex]
Required
Determine the coordinates of T
Midpoint is calculated as:
[tex]M(x,y) = \frac{1}{2}(x_1 +x_2,y_1+y_2)[/tex]
Where:
[tex](x,y) = (4,-3)[/tex]
[tex](x_1,y_1) = (1,5)[/tex]
Substitute these values in the above formula:
[tex](4,-3) = \frac{1}{2}(1 + x_2,5+y_2)[/tex]
Multiply through by 2
[tex]2 * (4,-3) = 2 * \frac{1}{2}(1 + x_2,5+y_2)[/tex]
[tex](8,-6) = (1 + x_2,5+y_2)[/tex]
By direct comparison:
[tex]1 + x_2 = 8[/tex] and [tex]5 + y_2 = -6[/tex]
Solving for x2
[tex]1 + x_2 = 8[/tex]
[tex]x_2 = 8 - 1[/tex]
[tex]x_2 = 7[/tex]
Solving for y2
[tex]5 + y_2 = -6[/tex]
[tex]y_2 = -6 - 5[/tex]
[tex]y_2 = -11[/tex]
Hence, the coordinates of T is: [tex](7,-11)[/tex]

The cost of a hotel room during Lacy’s trip is $325. The hotel room tax in the city she is in is 10.5%. What is the total cost of the hotel room?
Answer:
$359.13
Step-by-step explanation:
To find the total cost of her room we have to add the cost of the tax to the cost of the room.
To find the value of the tax, multiply the value of the room(325) by 10.5%:
Convert 10.5% to decimal form: 0.105
0.105 * 325 = 34.125
34.125 rounds up to 34.13.
Now, add the cost of the tax to the room's cost:
34.13 + 325 = 359.13
The total cost of the hotel room is $359.13.
The cost of a hotel room during Lacy’s trip is $325 and the hotel room tax in the city she is in is 10.5%, so the total cost of the hotel room will be $ 359.13.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that the cost of a hotel room during Lacy’s trip is $325. The hotel room tax in the city she is in is 10.5%.
The total cost of the hotel room is,
Total cost = hotel room tax + cost of a hotel room
Total cost = 10.5% of $325 + $325
Total cost = $ 34.12 + $325
Total cost = $ 359.13
Thus, the cost of a hotel room during Lacy’s trip is $325, and the hotel room tax in the city she is in is 10.5%, so the total cost of the hotel room will be $ 359.13.

HELP ASAP ! PLEASE I LOVE YOU MAY GOD BLESS YOU <3 :)
I can't answer the first question because you need to draw lines from one number to another and I'm not sure how to type that. The answer to the second question is choice 1.
Answer:
1) draw a colored in dot right above 0 with an arrow connected to it that points to the left of the graph
2) draw a white uncolored in dot right above 12 connected to an arrow that points to the left of the graph
6) draw a colored in dot right above -4 with an arrow connected to it that points to the right of the graph
7) draw a colored in dot right above 2 with an arrow connected to it that points to the left of the graph
For question 1 on the second image, the answer is Option 1. We would color in the dot right above 36 because the child an be 36 inches and still ride the ride, and we would leave the dot right above 48 uncolored because in order to ride the ride the child must be less than 48 inches they cannot be 48 inches or taller if they want to ride the ride.
Step-by-step explanation:
The inequality for the first question can be simplified to p [tex]\leq \\[/tex] 0, so just draw a colored in dot right above 0 with an arrow connected to it that points to the left of the graph (indicating that all values of p are less than or equal to 0)
The inequality for the second equation can be simplified to g < 12, so just draw a white uncolored in dot right above 12 connected to an arrow that points to the left of the graph (indicating that all values of g are less than 12)
The inequality for the problem that says 6), can be simplified to -4 [tex]\leq \\[/tex] c, so just draw a colored in dot right above -4 with an arrow connected to it that points to the right of the graph (indicating that all values of c are equal to or greater than -4)
The inequality for the problem that says 7), can be simplified to j [tex]\geq[/tex] 2, so just draw a colored in dot right above 2 with an arrow connected to it that points to the left of the graph (indicating that all values of j are equal to or greater than 2)
You've developed a protein drink that you think cures arthritis. to test it, you find 200 volunteers (100 men and 100 women) and test them to measure the amount of discomfort they feel from their arthritis. then you give the treatment to half the subjects and a placebo to the others. you then test them all at regular intervals and measure their improvement. you find that the subjects who received the treatment show marked improvement. the people performing the tests are not told that they're studying an arthritis medication. you excitedly report your findings in an infomercial that is seen by millions of people, and sales skyrocket. but were the test results truly useful for determining the effectiveness of the treatment? why or why not? a. no, there was no control. b. yes, it's a blind-study. c. yes, it's a valid before-and-after design. d. can't be determined without knowing how much improvement was measured. e. no, there was no replication.
Answer:
I would say C
Step-by-step explanation:
In this experiment the subjects do not know whether they are being given the real treatment or a placebo. Also the testers do not know that treatment for arthritis has been given. The subjects being given the treatment "show marked improvement" according to the tests. Therefore this is a valid double blind experiment, making C the correct choice.

Suppose the price of one item was $12, and the price of another item was $20. What would figuring out a common multiple of 12 and 20 tell you?
Answer:
hi
Step-by-step explanation:
I think the answer is a number
Figuring out a common multiple of 12 and 20 we can say with the help of the factor that,
The cost of 5 one-item is equal to the cost of 3 another-item.
The cost of 10 one-item is equal to the cost of 6 another-item.
What is a factor?A factor is a number that divides another number, leaving no remainder
We have,
Cost of one-item = $12
Cost of another-item = $20
We can find out some common multiple of both the numbers 12 and 20.
12 x 1 = 12 20 x 1 = 20
12 x 2 = 24 20 x 2 = 40
12 x 3 = 36 20 x 3 - 60
12 x 4 = 48 20 x 4 = 80
12 x 5 = 60 20 x 5 = 100
12 x 7 = 84 20 x 6 = 120
12 x 8 = 96
12 x 9 = 108
12 x 10 = 120
We see that we have two common multiples from the above multiples.
i,e 60 and 120
Now,
The factor in the multiples are:
12 x 5 = 60
12 x 10 = 120
20 x 3 = 60
20 x 6 = 120
This means that,
The cost of 5 one-item is equal to the cost of 3 another-item.
The cost of 10 one-item is equal to the cost of 6 another-item.
Thus,
Figuring out a common multiple of 12 and 20 we can say with the help of the factor that,
The cost of 5 one-item is equal to the cost of 3 another-item.
The cost of 10 one-item is equal to the cost of 6 another-item.
