I think you need to retype this one. The formatting makes this question difficult to understand.

Answer:

standard deviation- you can see how far each number varies, on average, from the average value of the list

median- calculates the average of the two numbers in the middle of a set of even count of numbers

mode- this function shows the most frequency occurring number in a set of numbers

rank- with this function you can determine the position of a number in an unarranged array or set

Answer: $\frac{8}{17}$ or 8:17

Step-by-step explanation:

For any angle x (other than right angle) in a right triangle ,the trigonometric ratio of sin x is given by :-

$\sin x=\frac{\text{side opposite to x}}{\text{Hypotenuse}}$

Given: A right triangle with hypotenuse = 68 units

The side adjacent to S = 60

Let h be the side opposite to S, then using Pythagoras in the given right triangle, we get

$(68)^2=60^2+h^2\\\\\Rightarrow\ h^2=68^2-60^2\\\\\Rightarrow\ h^2=1024\\\\\Rightarrow\ h=\sqrt{1024}=32$

Thus, the side opposite to S = 32 units

Now, the trigonometric ratio for sin S is given by :-

$\sin S=\frac{\text{side opposite to S}}{\text{Hypotenuse}}\\\\\Rightarrow\sin S=\frac{32}{68}=\frac{8}{17}$

Hence, the trigonometric ratio for sin S = $\frac{8}{17}$ or 8:17

1.Find the zeros of f(x) = x2 - 9

Marat540 [252]

So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket

the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well

Sam puts $500 in the bank and does not put any more money in or take any out for eight years. He receives 6% interest yearly, co

drek231 [11]

Answer:

$894

Step-by-step explanation:

0.06 x 500 x 8^1.25 (-9)= 500+ 403 = $903-9= $894

1.25 = 1/8 of 1 (-9)

1=each power.

8th year = $843.75

9th year = $894

Semi annually you can do the same as 16/1 -17
