Answer: 0.393 ; 0.9933
Step-by-step explanation:
Given that :
Mean lifetime follows an exponential distribution (m) = 6
a. What is the probability that the CPU fails in the next three years?
Using the poisson distribution formula :
1 - e^-λt
λ = 1/m = 1 / 6 = 0.1667
Probability of failure in next 3 years :
P(X < 3) = 1 - e^-λx
P(X < 3) = 1 - e^-0.1667*3
P(X < 3) = (1 - e^-0.5)
P(X < 3) = 1 - 0.6065306
P(X < 3) = 0.3934693
= 0.3935
b. Assume that your corporation has owned 10 CPUs for three years, and assume that the CPUs fail independently. What is the probability that at least one fails within the next three years?
Number of pc owned = 10
CPU failure is indepndent
Probability of atleast one fails :
1 - P(X ≥ 3)^n
P(X ≥ 3) = 1 - P(X < 3)
P(X ≥ 3) = 1 - 0.3935 = 0.607
Hence,
1 - P(X ≥ 3) = 1 - 0.6065^10
1 - P(X ≥ 3) = 1 - 0.0067345
1 - P(X ≥ 3) = 0.993265
= 0.9933

There are 23 red shirts and 16 white shirts they will be put onto shelves in piles of 8 how many shirts will not fit evenly into 8 piles
Given :
There are 23 red shirts and 16 white shirts they will be put onto shelves in piles of 8.
To Find :
How many shirts will not fit evenly into 8 piles.
Solution :
We need to find the number of shirts which will not fit evenly into 8 piles.
What we need is the remainder of 23 divided by 8.
23 = 8×2 + 7
So, their are 7 shirts which will not fit evenly.
Hence, this is the required solution.

If g(x) = 3x - 1 and if g(a) = 7, then which of the following is the value of a?
Answer:
So,
[tex]g(x) = 3x - 1[/tex]
And,
[tex]g(a) = 3a - 1[/tex]
But, given g(a) = 7
So, from 2nd and 3rd step,
3a-1=7
3a=6
Therefore, a = 2
Answer:
8/3
Step-by-step explanation:
So if a=x then 3a-1=7 therefore 3a=8 and a=8/3

Jennifer and two friends went out to eat. Their bill was $54.25 and they need to pay tax of 8% and leave a 17% tip. If they split the bill evenly, how much will they each pay?
Answer: $22.8501
Step-by-step explanation:
Since their bill was $54.25 and they need to pay tax of 8% and leave a 17% tip, the total amount that will be paid will be:
= $54.25 + (8% × $54.25)
= $54.25 + (0.08 × $54.25)
= $54.25 + $4.34
= $58.59
We then add the 17% tip. This will be:
= $58.59 + (17% × $58.59)
= $58.59 + (0.17 × $58.59)
= $58.59 + $9.9603
= $68.5503
Since they want to split the bill evenly, we divide the total amount gotten by 3. This will be:
= $68.5503 / 3
= $22.8501
Each person will pay $22.8501

In a probability experiment, Craig rolled a six-sided die 64 times. The die landed on a number greater than three 39 times. What is the ratio of rolls greater than three to rolls less than or equal to three?
A.
B.
C.
D.
Answer:
The ratio is 34/22, or in simplest form, 17/11.
Step-by-step explanation:
We write the ratio with the number of rolls greater than three on top and the number of rolls less than or equal to 3 on bottom:
34/(56-34)
We have to subtract 34 from 56 to find out how many rolls were less than or equal to 3.
34/22
Both are divisible by 2, so we have 17/11.
Hey, people so I have a question, so my sister is scared of toilet paper and gets mad at me when I make fun of her. She says it might be that she has OCD and gets upset saying I mock her but, but she literally has no signs of OCD and I think she's being weird. So like can yall tell me your opinions if she has issues or she just being weird.
I Googled the symptoms. They are as follows:
Behavioural: compulsive behaviour, agitation, compulsive hoarding, hypervigilance, impulsivity, meaningless repetition of own words, repetitive movements, ritualistic behaviour, social isolation, or persistent repetition of words or actions
Mood: anxiety, apprehension, guilt, or panic attack
Psychological: depression or fear
Also common: food aversion, nightmares, or repeatedly going over thoughts
I think she is just being wierd. I myself sometimes get scared by looking in the sky. I think that what if I leave the Earth and wander in the space and I don't have any oxygen to breathe. Ask your sister what makes her scared of toilet paper. Don't make fun of her or she will not share her thoughts with you.

It takes 4 pounds of apples to make 6 cups of applesauce. At this rate, how much applesauce can you make with 7 pounds of apples?
Answer:
10 1/2 cups.
Step-by-step explanation:
4 pounds of apples make 6 cups apple sauce.
So 1 pound apples makes 6/4 = 1 1/2 cups of sauce.
7 pounds will make 1 1/2 * 7
= 10 1/2 cups sauce.
10 and 1/2 cups sauce can be made with 7 pounds of apples.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
4 pounds of apples = 6 cups apple sauce.
So, 1 pound apples makes = 6/4
Now, 7 pounds will make 1 1/2 * 7
= 7 x 6/4
= 7 x 3/2
= 21/2 cups sauce.
Hence, 10 and 1/2 cups sauce can be made with 7 pounds of apples.

During the Lakers game, Kobe made 19 shots; some were 2-pointers and the others were 3-pointers. If he scored 45 points, how many were 2 pointers. How many 3-pointers?
Five 3 pointers and two 2 pointers
Step-by-step explanation:
The required expression that represents the number of 2 pointers and 3 pointers scored is 2x + 3y = 45 where x represents the number of 2 pointers and y tend the number of 3 pointers.
Given that, During the Lakers game, Kobe made 19 shots; some were 2-pointers and the others were 3-pointers. If he scored 45 points, how many were 2 pointers. How many 3-pointers is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number of 2 pointer be x and the number of 3 pointer be y,
According to the question,
2x + 3y = 45
where x represents the number of 2 pointers and y tend the number of 3 pointers.
Thus, the required expression that represents the number of 2 pointers and 3 pointers scored is 2x + 3y = 45.
