For this case we substitute the point in each of the equations and verify if the equality is met:
Option 1:

It is not true
Option 2:

It is not true
Option 3:

Is fulfilled
Option 4:

Answer:
The point belongs to the equation of the third option.
The answer is 2 because if the diameter is the full length of the circle From one side of the circle to the other and you’re trying to find the radius which is from the center of the circle to any point on the circumference of the circle you would difrom one side of the circle to the other and you’re trying to find the radius which is from the center of the circle to any point on the circumference of the circle you would divide the diameter by 2.
Answer:

Step-by-step explanation:
Hello,
for any real x different from 1

if f(x)=2x
f'(x)=2
if g(x)=-ln(1-x)

So antiderivative of

Is
2x-ln(1-x)
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
Step-by-step explanation:
In this question, the sample space contains 8 elements and has been given as;
HHT HHH THH HTH HTT TTT TTH THT
1. For event A:
Outcomes of alternating tail and head = THH HTH HTT THT
= 4 outcomes
Pr(alternating tail and head (with either coming first)) = 
= 
2. For event B:
Outcomes of no tails on the first two tosses = HHT HHH
= 2 outcomes
Pr (No tails on the first two tosses) = 
= 
For event C:
Outcomes of a tail on both the first and the last tosses = THT TTT
= 2 outcomes
Pr(A tail on both the first and last tosses) = 
=
