A function is an operation you perform to a number or expression. For example, my function could be "add five to the input". Now the input is what you have before you use the function; it's what you put into the function. For example, my input could be the number 7. If I put it through my function of adding five, I get 7+5=12. 12 is the output; what you have after you put it through the function. Hope this helped.

Answer: 1.460

Step-by-step explanation:

Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.

Let $\mu$ represents the population mean .

Then, the set of hypothesis will be:-

$H_0: \mu=15$

$H_a:\mu\neq15$

We assume that this is normal distribution.

Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.

Sample mean : $\overliene{x}=16.2\ lbs$

Standard deviation : $\sigma=2.6$

The test statistic for population mean for small sample is given by :-

$t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t=\dfrac{16.2-15}{\dfrac{2.6}{\sqrt{10}}}=1.45951276623\approx1.460$

Hence , the value of test statistic = 1.460

Tickets for a school jazz concert were sold before the concert and at the door. After reviewing ticket sales, the band director

Alex73 [517]

Answer: The answer is:

d=220, b=300

Step-by-step explanation:

You could solve this problem using a series of equations:

d+b=520

b-80=d

How I solve this is:

If d+b=520, you could divide 520 by 2 and say that d and b's average is 260 (though that is not their value).

Then , you know that the difference between them is 80. Since the average is 260, you could add half of 80 (which is 40) and subtract the same to get 220 and 300, which, as you can see, have a difference of 80 and add up to 520. Now you have to find out which is which.

Since 80 fewer tickets were purchased at the door than before the concert (d+80=b (the second equation)), you know that the number of tickets at the door is the lesser number, making the answer:

d=220, b=300
