Since there are only two sides (heads & tails) to a coin:
Probability (as fraction) - 1/2
Probability (as percent) - 1/2 x 100 = 50%
Probability (as decimal) - 1 x 50/2 x 50 = 50/100 = 0.5


(P.S. Please mark this answer as the brainliest answer... Thank You)

<u>→ Chapter : Probability ←</u>
<u><em>≡ We know that:</em></u>
⇔ There is only 2 option in one coin, Those are head and tails 
⇔ n(A)=1
⇔ n(S)=2

<u><em>≡ Solution:</em></u>
⇒ P(A)= \frac{n(A)}{n(S)}= \boxed{\frac{1}{2}} [In form of fraction]
⇒ (\frac{1}{2}).(100)=\boxed{50}Percent [In form of percent]
⇒ \frac{1}{2}=\frac{50}{100}=\boxed{0,5} [In form of decimal]

Answer:

A proportional relationship is there.

Step-by-step explanation:

Here in the table, the values of y are given corresponding to the values of x.

There are four sets of values of x and y.

We have to check whether the relationship is proportional or not.

Now, rate of change of y with respect to x will be from the first two pair of values is = \frac{3.5 - (-1)}{-2 - (-8)} =0.75

Again, rate of change of y with respect to x will be from the second two pair of values is = \frac{12.5 - 3.5}{10 - (-2)} =0.75

And, rate of change of y with respect to x will be from the third two pair of values is = \frac{20-12.5}{20 - 10} =0.75

So, the rate is always 0.75.

Therefore, a proportional relationship is there. (Answer)

Determine algebraically whether the function is even, odd, or neither even nor odd.
m_a_m_a [10]
For a function (fn) to be odd:
f(x) = - f(-x)
For a fn to be even:
f(x) = f(-x)
For a fn to be neither even nor odd
f(x) != f(-x)  [No Relation]

(-x)^n = x^n   for n -> even
(-x)^n = -x^n  for n -> odd
In your example:

f(x) = -4x^3 + 4x
f(-x) = -4 (-x)^3 + 4 (-x)^1  ( 3 and 1 are odd powers )
f(-x) = 4x^3 - 4x   (take -1 common to do the check)
f(-x) = -( -4x^3 + 4x ) = - f(x)  [between the bracket was the original fn]

f(x) = - f(-x)   
so the function is odd also called symmetric about the origin

NEED URGENT HELP
AnnyKZ [126]

Answer:

32.5

Step-by-step explanation:

If CED is 65, then AEB is 65, therefore we can calculate that CEA is 115 because 180 - 65 = 115. Then we do 180 - 115 = 65 which is the sum of angles ACE and CAE so 65 / 2 = 32.5 which is CAE.

Hope this helped!

REAL LIFE A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet. Abo
aivan3 [116]

Answer:

It can hold up to 1.256ft^3 of waste

<em></em>

Step-by-step explanation:

Given

D = 1.5ft -- Diameter

h = 1.6ft -- height

Required

Determine the amount of waste it can hold

This simply means that we calculate the volume of the cylindrical container.

And this is calculated using:

Volume = \pi r^2h

Where

\pi = 3.14

and

r = \frac{D}{2}

r = \frac{1.5}{2}

r = 0.75

So, we have:

Volume = 3.14 * 0.5^2 * 1.6

Volume = 1.256ft^3

<em>Hence, it can hold up to </em>1.256ft^3<em> of waste</em>
