$x^2+y^2=169$
$y^2=169 -x^2$
$y= \sqrt{ 169 -x^2}$
$f(x)= \sqrt{ 169 -x^2}$

What is the experamental probability that the coin lands on heads?

sammy [17]

Answer:

The experamental probability that the coin lands on head is 50 %

Step-by-step explanation:

Given:

Experiment:

A coin is Toss

Let the Sample Space be 'S' that is total number of outcomes for a coin has been tossed = { Head, Tail }

∴ n ( S ) = 2

Let A be the event of getting a Head on tossing a coin i.e { Head }

∴ n( A ) = 1

Now,

$\textrm{Probability} =\frac{\textrm{outcomes for the experiment}}{\textrm{total number of outcomes}}$

Substituting the values we get

$P(A) = \frac{n(A)}{n(S)} \\\\P(A) = \frac{1}{2} \\\\P(A) = 0.5\\\\P(A) = 50\%$

The experamental probability that the coin lands on head is 50 %

Suppose y varies inversely as x, and y = 16 when x = 1/2. Find y when x = 17.

MArishka [77]

Finding the proportionality constant :

y = k/x
16 = k/(1/2)
k = 8

Finding y when x = 17 :

y = 8/(17)
y = 8/17

The value of y is 8/17 when x = 17.
