Answer: 0.12 per minute
Step-by-step explanation: I actually had to reread this one a couple times, as the setup is a bit confusing. Here's how I would solve it personally:
1. Since it's leaking 2ml per second, and there are 60 seconds in a minute, multiply 2ml times 60 seconds to get 120ml every minute.
2. 1ml equals 0.001 liters, so multiply 120ml by 0.001 to find out how many liters that is. 120(0.001)=0.12.
Hope this helps,

Answer:
y= 13/4x - 21
Step-by-step explanation:
What we need to do is find the slope first. We know the slope formula is
y_1 minus y_2/ x_1 minus x_2. I am assuming that one point is (8,5) the other is (4,-8). So when we insert these coordinates into the equation,
[5-(-8)/8-4] we result with 13/4 as the slope. We can now use the slope-intercept form! ( y=mx+b) 13/4 can be put into this equation as m, because its the slope. So, now we have y=13/4x+b. The last step to find the equation is inserting the first coordinates given.(8,5) 5= 8(13/4)+b. 8 times 13 divided by 4 is 26. This is what we factored to so far: 5= 26+b. We are trying to solve for b! So lastly, 5-26= -21 and that is b. Once again, we can use the slope intercept formula since we know both b and the slope. FINAL ANSWER: y=13/4x-21. I hope this can help!

A market sells 7 oranges for2.45 how muck will 8 oranges cost
Answer:
17.15
step by step explanation
2.45 divided by seven equals .35.
So each oranges is .35¢
So now multiply .35 by 8 and you’ll get a total of $2.80
$2.80 for 8 oranges.
The value of one score in a distribution is changed from X = 20 to X = 30. Which measure(s) of central tendency is (are) certain to change?
Answer:
Mean
Step-by-step explanation:
The three basic measures of central tendencies are mean, median and mode.
Mean can be described as the average value of a set of numbers or scores in a distribution.
One of the ways the mean can be calculated is by dividing the sum of the scores in a distribution by the number of scores in the distribution. This can be represented mathematically as follows:
Mean = Sum of the scores in a distribution / Number of scores in the distribution ........ (1)
Median is the middle number when the scores in a distribution is arranged in ascending or descending order.
Mode is the most frequent number or score in a distribution.
Out of the three basic measures of central tendencies only the mean will certainly change when there is a change in one of the scores. This is because, we can still have the same score as the most frequent and the same number as the median but the mean will change.
For example, we can prove that the mean will certainly change if we assume that the sum of the scores in a distribution is 200 and number of scores in the distribution is 10, wee can substitute this into equation (1) and have:
Mean = 200 / 10 = 20
Now, as given in the question, if the value of one score in the distribution is changed from X = 20 to X = 30. We can obtain the difference as follows:
Difference in score = 30 - 20 = 10
The new mean can be calculated as follows:
New mean = (200 + Diffrence in score) / 20 = (200 + 10) / 20 = 210 / 20 = 21
Therefore, the mean changed by 1 from 20 to 21. This therefore proves that the mean will certainly change.
Of the measures of central tendency, the measure which will certainly change is the mean.
Measures of central tendency include mean, median and mode of a distribution.
The mean refers to the average, hence, the a change in one value in the distribution would certainly change the mean of the distribution.
The mode refers to the highest occurring value in the distribution.
Median denotes the number at the middle of a distribution once it is arranged in order of magnitude.
For instance :
2, 2, 10, 15, 20The mean = (2 + 2 + 10 + 15 + 20) / 5 = 49/5 = 9.8
Mode = 2 (highest occuring)
Median = 10 (middle value)
If X = 20 is changed to X = 30
2, 2, 10, 15, 30The mean = (2 + 2 + 10 + 15 + 30) = 59/5 = 11.8
Mode = 2 (highest occuring)
Median = 10 (middle value)
Therefore, the measure which would certainly change is the mean.

Decide if the situation involves permutations, combinations, or neither. Explain your reasoning. The number of ways 13 people can line up in a row for concert tickets. Does the situation involve permutations, combinations, or neither? Choose the correct answer below.
Step-by-step explanation:
The situation involves permutation. Permutation deals with arrangements of objects. It talks about ways peoples or objects can be arranged with or without restriction. According to the question,
The number of ways 13 people can line up in a row for concert tickets can be expressed as
13! = 13 * 12 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
13! = 6,227,020,800 ways
Hence the number of ways 13 people can line up in a row is 6,227,020,800 different ways and the situation involves permutation.

The time until recharge for a battery in a laptop computer under common conditions is normally distributed with mean of 270 minutes and a standard deviation of 50 minutes. a) What is the probability that a battery lasts more than four hours
Answer:
The answer is below
Step-by-step explanation:
The time until recharge for a battery in a laptop computer under common conditions is normally distributed with mean of 270 minutes and a standard deviation of 50 minutes. a) What is the probability that a battery lasts more than four hours b) What are the quartiles (the 25% and 75% values) of batterylife? c) c) What value of life in minutes is exceeded with 95% probability? (Roundthe answer to the nearest integer.)
Solution:
The z score is used to determine by how many standard deviations the mean is above or below the raw score. If the z score is positive then the raw score is above the mean while if the z score is negative then the raw score is below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean, \sigma=standard\ deviation[/tex]
Given μ = 270 minutes, σ = 50 minutes
a)
P(x > 4 hours) = P(x > 240 minutes)
[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{240-270}{50} =-0.6[/tex]
From the distribution table, P(x > 240) = P(z > -0.6) = 1- P(z < 0.6) = 1 - 0.2743 = 0.7257
c) P(z > z*) = 0.95
1 - P(z < z*) = 0.95
P(z < z*) = 0.05
This corresponds to a z score of -1.645
[tex]z=\frac{x-\mu}{\sigma}\\ \\-1.645=\frac{x-270}{50} \\\\x=187.75 \ minutes[/tex]
For 75%, P(z < z*) = 0.75
This corresponds to a z score of 0.68
[tex]z=\frac{x-\mu}{\sigma}\\ \\0.68=\frac{x-270}{50} \\\\x=304 \ minutes[/tex]
c) For 25%, P(z < z*) = 0.25
This corresponds to a z score of -0.67
[tex]z=\frac{x-\mu}{\sigma}\\ \\-0.67=\frac{x-270}{50} \\\\x=236.5 \ minutes[/tex]
What is the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI
Complete Question
Super Bowl XLVI was played between the New York Giants and the New England Patriots in Indianapolis. Due to a decade-long rivalry between the Patriots and the city’s own team, the Colts, most Indianapolis residents were rooting heartily for the Giants. Suppose that 90% of Indianapolis residents wanted the Giants to beat the Patriots. What is the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI?
Answer:
The value is [tex]P(X < 0.95) = 0.95224[/tex]
Step-by-step explanation:
From the question we are told that
The proportion that wants Giants to win p = 0.90
The sample size is n = 100
Generally the mean of this sampling distribution is
[tex]\mu_{x} = 0.90[/tex]
Generally the standard deviation is
[tex]\sigma = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{ 0.90 (1- 0.90)}{100} }[/tex]
=> [tex]\sigma = 0.03[/tex]
Generally the probability that from a sample of 100 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI is mathematically represented as
[tex]P(X < 0.95) = P(\frac{ X - \mu_{x}}{\sigma} < \frac{0.95 -0.90}{0.03} )[/tex]
[tex] \frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 0.95) = P(Z < 1.667 )[/tex]
=> [tex]P(X < 0.95) = 0.95224[/tex]
