Mean = 78
x - mean         squared

80-78 = 2              4
74-78= -4            16
77-78 = -1             1
75-78 = -3             9
91-78 = 13        169

  Total               199

standard deviation  = square root  (199/6) =  5.8 to nearest tenth

For the function f(x)=-3x+2, find f(2)=
dsp73

Answer: f(2) = -4

Step-by-step explanation: Here we're given the function f(x) = -3x + 2 and we are asked to find f(2).

In other words, if we put an <em>x</em> into our function, we get a -3x + 2 out so what happens when we put a 2 into the function?

Well if we put a 2 into the function,

that's f(2) and we get -3(2) + 2 out.

Now all we have to do is simplify on the right side.

-3(2) is -6 so we have -6 + 2 which is -4.

So f(2) is -4.

A UCF graduate has 3 bank overdrafts per year, and the bank charges $35 per overdraft. The bank pays the graduate 1% interest pe
Elena L [17]

Answer:

$33

Step-by-step explanation:

First we calculate the cost of the overdrafts:

3 overdrafts * $35 = $105

Then, if he maintains an average monthly balance of $600, we can calculate = $600*12 months = $7200 (average yearly balance). And the bank pays him 1% interest per annum:

$7200 * 1% = $72 (this is what the bank pays the graduate per year)

So if the bank charges him $105 and pays him $72, then the net annual cost is = $105-$72= $33
