When flipping a coin three times, what is the probability of landing on heads all three times?

A coin has 2 sides....heads and tails....so the probability of it landing on heads is 1/2....the same as the probability of it landing on tails is 1/2.

Therefore, the probability of it landing on heads on 1 coin flip is 1/2.

so the probability of it landing on heads on 3 coin flips is :
1/2 * 1/2 * 1/2 = 1 / 8 <==

Show all work to identify the discontinuity and zero of the function f of x equals 4 x over quantity x squared minus 16
Leto [7]

Answer:

Discontinuity of function occurs when x = 4 or x = -4

zero of function is when x=0

Step-by-step explanation:

We are given:

f(x) = \frac{4x}{x^2 - 16}

Discontinuity of the function occur when the denominator is equal to zero.

So, we need to find the values of x that makes the denominator zero.

The denominator is x^2 - 16

x^2 - 16 =0

x^2 = 16

x = ± 4

So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.

Zero of the function i.e f(x)=0

So, Putting the function equal to zero and finding the value of x

\frac{4(x)}{(x)^2 - 16}=0\\4x =0((x)^2 - 16)\\4x=0\\x=0

So, zero of function is when x=0

If y = 3 when x = 2. find x when y = 5.
ahrayia [7]
Y = 3   x = 2
if y = 1  x = ?

x = 3/2
x = 1.5
x = 5*1.5 ( y = 5  x = ?)
x = 7.5       
(IF THE ANSWER IS WRONG)
may be this can be that answer

x = 2/3
x = 0.67
x = 0.67*5
x = 3.35

check the answer either first or second method is correct

Need help with 61. Show steps please.
skelet666 [1.2K]
Just do 3x+5+2x=90 And solve for x.

So, 5x+5=90
5x=85
x=85/5 = 17

now you know the value of x, so you can calculate the angles.

Btw the total angle of a triangle is 180, and since this is a right angle triangle, you know that the two angles added together needs to equal 90.
