Answer:You can put this solution on YOUR website!

The numbers are between +/- 2 sd s of the mean

With Chebyshev's inequality, at least 3/4 of the numbers would be between these two.

For the one with 3 standard deviations, it would be 8/9.

----------------------

For the second part, this is 3.5 sd s on either side

1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49.

----------------

The second one would be wishing 18/8 or 2.25 sd s and that fraction would be 1/(9/4)^2=1/81/16 or 16/81 or 0.1975.

F you have $18 and a 15% markup, what is the retail price?

Serggg [28]

OK so first I like to find what 10% is which in this case would be 1.8 and to find the other 5% you divide 1.8 by 2 which gets you .9 if you and 1.8 and .9 you get 2.7 and if you add 2.7 to 18 you get 20.7 which is your retail price

Which could be the function graphed below?

iren [92.7K]

9514 1404 393

Answer:

(a) f(x) = √x -2

Step-by-step explanation:

The square root function has no horizontal shift, so the expression under the radical is simply x with no added terms. There is only one such answer choice, which also shows the necessary translation downward by an added negative constant.

$f(x)=\sqrt{x}-2$
