Matrix tossed three coines wat is the probability that all three coins will land on the same side

Mathematics
1 answer:
Anna35 [415]2 years ago

Answer: 1/4

Step-by-step explanation:

This problem is very interesting, because it does not specify which side the coin must land on.  Thus, the first flip has a 100% of landing on one side, then the next two have a 50% chance of landing on the same side.  Thus, the probability is 1*.5*.5, or .25, or 1/4

Find the quotient. 28 over 0
Jlenok [28]
I am assuming 28/0.  The short answer is that it is infinity.  (Or they may want undefined)

Here is a bit longer explination:
Let's start by taking 28/1, that gives 28. What about 28/0.5 that gives 56, and as we keep decreasing the denominator closer to zero then the quotient will become larger and larger.  We we reach zero, the quotient becomes so large that it is considered infinity.

<h3>Answer:</h3>

f(x) = 0 \text{ when } x = \bold{1}

f(-7) =\bold{224}

<h3>Step-by-step explanation:</h3>

Solving for the input, \bold{x}, given the output:

Given:

f(x) = 4x -4

Solving for x from the equation, f(x) = 0:

f(x) = 0 \\ 4x -4 = 0 \\ 4x = 4 \\ x = \frac{4}{4} \\ x = 1

Solving for the output, \bold{f(x)}, given the input.

Given:

f(x) = 4x^2 -4x

Solving f(-7):

f(-7) = 4(-7)^2 -4(-7) \\ f(-7) = 4(49) -4(-7) \\ f(-7) = 196 +28 \\ f(-7) = 224

A machine needs 2 of its gears replaced. You find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago.
Tcecarenko [31]
Probability that gear 1 will fail = 5/100 (upto 10 years) 
and 8/100 (after 10 years)

Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %
