We can write it down like this:
4%*x=56
where we want to find the x
first, i would change the % into fraction.
multiply both sides by 100
divide by four:
and that's our answer, 1400!
This situation represents inverse variation.
The difference between direct and inverse variation is in direct variation, as one variable goes up the other does too, while in inverse, as one variable goes up the other falls.
In this case, as you donate to more charities, the amount you donate to each charity falls, because you donate an equal amount. This means it's inverse variation.
Hope this helps!
Answer with explanation:
By definition of mean life we know that on an average the respective phones will last for 2.5 years or 3 years respectively but for each model there will be phones which last less than the mean life and phones which last for greater than the mean life.A lower standard deviation means that all the phone batteries have life close to mean life while as a larger standard deviation means that the lives of the batteries are spread out. The Percentage of such phone which last for time greater or lesser than mean depends on the standard deviation of the data.
Since we will get a phone at random from the samples we need to maximize our chances of getting a better phone which can be obtained only if we know the standard deviation of the data.
Part b)
Yes it changes our opinion of the given batteries since for the battery with life of 2.5 years has a lesser deviation thus we infer if we choose any battery from this sample at random we have larger chances that the battery has the specified or greater life span while as the chances in the second type of battery are lower.
Answer:
The percent increase in the advance-purchase deadline is 30% because if you divide $90 by 10 you get 9 and multiply that by 3 and you will get an 30% increase
