Two experiments are to be performed. The first can result in any one of m possible outcomes. If the first experiment results in
Galina-37 [17]

Answer: The first experiment has M probabilities, and the second has I(m) outcomes, that depends on the result of the first.

And lets call m to the result of the first experiment.

If the outcome of the first experiment is 1, then the second experiment has 1 possible outcome.

If the outcome of the first experiment is 2, then the second experiment has 2 possibles outcomes.

If the outcome of the first experiment is M, then the second experiment has M possibles outcomes.

And so on.

So the total number of combinations C is the sum of all the cases, where we exami

1 outcome for m = 1

2 outcomes for m=2

+

+

M outcomes for m = M

C = 1 + 2 + 3 + 4 +...´+M

Expand and simplify (x+5)(x-2)
neonofarm [45]

Answer:

{x}^{2}  + 3x  - 10

Step-by-step explanation:

(x + 5)(x - 2)

utilise the Foil method to expand brackets:

F - mulply the first terms (x and x)

O - multiply the outside terms ( x and -2)

I - multiply the inside terms (5 and x)

L - multiply the last terms (5 and -2)

Then add them as following:

{x}^{2}   - 2x + 5x - 10

Then combine like terms:

{x}^{2}  + 3x - 10

What is the value of c in the equation below?! HELP
prisoha [69]

Note that when dividing, and the base is the same, you can subtract the power signs.

(5^5)/(5^2) = 5^(5 - 2)

5 - 2 = 3

5^3 = a^b

Simplify.

5^3 = 5 x 5 x 5

5 x 5 x 5 = 125

c = 125

----------------------------------------------------------------------------------------------------------------

125 is your answer

hope this helps
