A friend of yours claims to be able to ride a bicycle 20 feet per second, is this a reasonable
speed for a bicycle? Help
Answers
Answer:
No and yes
Step-by-step explanation:
If the bike is at a sudden hault (A FULL STOP) its physically impossible for the sudden speed of his weight and laws of inertia to pull him forwar that quick.
NOW - if the bike is already in motion and going downhill the gravitational down force will haul his speed at 45MPH and would make him reach the lenght of 66feet per second.

4. Calculate the values for the ASN curves for the single sampling plan \( n=80, c=3 \) and the equally effective double sampling plan \( n_{1}=50, c_{1}=1, r_{1}=4, n_{2}=50, c_{2}=4 \), and \( r_{2}
Answers
Single Sampling Plan: AQL = 0, LTPD = 3.41, AOQ = 1.79 Double Sampling Plan: AQL = 0, LTPD = 2.72, AOQ = 1.48
The values for the ASN (Average Sample Number) curves for the given single sampling plan and double sampling plan are:
Single Sampling Plan (n=80, c=3):
ASN curve values: AQL = 0, LTPD = 3.41, AOQ = 1.79
Double Sampling Plan (n1=50, c1=1, r1=4, n2=50, c2=4, r2):
ASN curve values: AQL = 0, LTPD = 2.72, AOQ = 1.48
The ASN curves provide information about the performance of a sampling plan by plotting the average sample number (ASN) against various acceptance quality levels (AQL). The AQL represents the maximum acceptable defect rate, while the LTPD (Lot Tolerance Percent Defective) represents the maximum defect rate that the consumer is willing to tolerate.
For the single sampling plan, the values n=80 (sample size) and c=3 (acceptance number) are used to calculate the ASN curve. The AQL is 0, meaning no defects are allowed, while the LTPD is 3.41. The Average Outgoing Quality (AOQ) is 1.79, representing the average quality level of outgoing lots.
For the equally effective double sampling plan, the values n1=50, c1=1, r1=4, n2=50, c2=4, and r2 are used. The AQL and LTPD values are the same as in the single sampling plan. The AOQ is 1.48, indicating the average quality level of outgoing lots in this double sampling plan.
These ASN curve values provide insights into the expected performance of the sampling plans in terms of lot acceptance and outgoing quality.

A spinner with the words grape(G), apple(A), orange (O), and pear(P) is spun 30
times. What is the experimental probability of landing on the word apple(A)?
P(apple)
Answers
Answer:
To calculate the experimental probability of landing on the word apple (A), you need to know how many times the spinner landed on apple (A) out of the 30 spins. Experimental probability is calculated by dividing the number of times the event occurred by the total number of trials.
In this case, the formula for calculating the experimental probability of landing on apple (A) would be:
P(apple) = (Number of times spinner landed on apple) / (Total number of spins)
Without knowing how many times the spinner landed on apple (A), it is not possible to calculate the experimental probability.

a school is running a fundraiser by selling 2000 raffle tickets for various cash prizes. Each raffle ticket costs $5. There are two prizes worth $10, two prizes worth $20, two prizes worth $100, and one grand prize ticket worth $500. Assuming all raffle tickets are sold and that you only buy one ticket, find your expected winnings
Answers
Your expected winnings from buying one raffle ticket are approximately $0.38.
To find your expected winnings, we need to calculate the probability of winning each prize and multiply it by the corresponding prize amount. Since you are only buying one ticket, we can calculate the expected winnings as follows:
Expected winnings = (Probability of winning $10) * $10 + (Probability of winning $20) * $20 + (Probability of winning $100) * $100 + (Probability of winning $500) * $500
The probability of winning each prize depends on the total number of tickets sold and the number of tickets available for each prize.
Given that there are 2000 raffle tickets sold and the distribution of prizes, we can calculate the probabilities as follows:
Probability of winning $10 = (Number of $10 prizes) / (Total number of tickets sold) = 2 / 2000 = 0.001
Probability of winning $20 = (Number of $20 prizes) / (Total number of tickets sold) = 2 / 2000 = 0.001
Probability of winning $100 = (Number of $100 prizes) / (Total number of tickets sold) = 2 / 2000 = 0.001
Probability of winning $500 = (Number of $500 prizes) / (Total number of tickets sold) = 1 / 2000 = 0.0005
Now, we can calculate the expected winnings:
Expected winnings = (0.001) * $10 + (0.001) * $20 + (0.001) * $100 + (0.0005) * $500
Expected winnings = $0.01 + $0.02 + $0.1 + $0.25
Expected winnings = $0.38
Therefore, your expected winnings from buying one raffle ticket are approximately $0.38.

I would like an explanation how to do it too, IF you dont mind.
Answers
Answer:
Phoebe has £180, Andy has £60, and Polly has £30.
Step-by-step explanation:
Ok, to start of let's establish some variables! We'll give Phoebe the variable "p", Andy the variable "a", and Polly the variable "o". By giving each person a variable we can create an equation and solve for it!
So, what do we know?
Well we know the following information...
p + a + o = 270
(Phoebe + Andy + Polly = £270)
p = 3a
(Phoebe = 3 times more than Andy)
a = 2o
(Andy = 2 times more than Polly)
To be able to solve this equation we have to solve for just one variable first.The only one we can use is "o" for Polly!
3(2o) + 2o + o = 270
6o + 2o + o = 270 (Distribute 3 to get like terms)
9o = 270 (Combine like terms [6+2+1])
o = 30 (Divide by 9 on both sides to get "o" by itself)
Now that we have how much Polly has, we have to solve for Andy and Phoebe. (To do this we will input our value, 30, where our variable is "o")
Andy
a = 2(30) (Input term)
a = 60 (Multiply by 2 to get final answer)
(Since we now know what Andy has we can input 60 into our "a" variable to solve for Phoebe)
Phoebe
p = 3(60) (Input term)
p = 180 (Multiply by 3 to get final answer)
Now! Just to check we are going to input our variables into our original equation to be sure we have the right variables.
p + a + o = 270
180 + 60 + 30 = 270!!
Hope this Helps! :)

Step-by-step explanation:
Each year, Knight Motors surveys 7,600 former and prospective customers regarding satisfaction and brand awareness. For the current year, the company is considering outsourcing the survey to RBG Associates, which has offered to conduct the survey and summarize results for $35,000. Craig Knight, the president of Knight Motors, believes that RBG will do a higher-quality job than his company has been doing but is unwilling to spend more than $10,000 above current costs. The head of bookkeeping for Knight has prepared the following summary of costs related to the survey in the prior year:
Mailing $17,500
Printing (done by Lester Print Shop) 6,000
Salary of Pat Fisher, part-time employee who stuffed envelopes and summarized data when surveys were returned (130 hours × $16) 2,080
Share of depreciation of computer and software used to track survey responses and summarize results 1,200
Share of electricity/phone/etc. based on square feet of space occupied by Pat Fisher vs. entire company 600
Total $27,380
REQUIRED
What is the incremental cost of going outside vs. conducting the survey as in the past? Will Craig Knight accept the RBG offer?
Answers
The incremental cost of outsourcing the survey to RBG Associates is $25,000. Based on Craig Knight's spending limit, he will not accept the RBG.
1. Determine the current cost of conducting the survey in-house. To do this, add up all the costs provided in the question.
2. Calculate the incremental cost by subtracting the current cost from the cost of RBG Associates' offer: $35,000 - $10,000 (current cost) = $25,000.
3. Compare the incremental cost with Craig Knight's spending limit. In this case, $25,000 is more than the $10,000 limit he is willing to spend, so he will not accept the RBG offer.
Since the incremental cost of outsourcing the survey is less than Craig Knight's budget constraint of $10,000, he will accept the RBG offer if he believes that RBG will do a higher-quality job than his company has been doing.
Therefore, outsourcing the survey to RBG Associates appears to be a viable option for Knight Motors as it would result in higher quality survey results at a relatively low incremental cost.

Answer:
(5, -2), or x = 5 and y = -2.
Step-by-step explanation:
We can solve the two equations algebraically by eliminating a variable:
2x + 5y = 0
3x - 4y = 23
Eliminate the x variable by finding the least common multiple and multiplying both equations:
3(2x + 5y = 0)
2(3x - 4y = 23)
Distribute and subtract the bottom equation from the top:
6x + 15y = 0
6x - 8y = 46
------------------
0x + 23y = -46
23y = -46
y = -2.
Plug in y into an equation to solve for x:
2x + 5(-2) = 0
2x - 10 = 0
2x = 10
x = 5. Therefore:
The solution to this equation is (5, -2), or x = 5 and y = -2.
Answer:
x = 5; y = -2
Step-by-step explanation:
2x + 5y = 0
3x - 4y = 23
Let's eliminate y. Multiply the first equation by 4. Multiply the second equation by 5. Then add them.
8x + 20y = 0
(+) 15x - 20y = 115
------------------------------
23x = 115
x = 5
Now we substitute 5 for x in the first equation and solve for y.
2(5) + 5y = 0
5y = -10
y = -2
Solution: x = 5; y = -2
