Mathematics
1 answer:
MArishka [77]3 years ago
5 0

1/2 (2n+6) = 5n - 12 - n

n + 3 = 4n - 12

n + 15 = 4n

15 = 3n

n = 5

(Essay Question 7 Points)
Irina18 [472]

Well I don't know.
Let's think about it:

-- There are 6 possibilities for each role.
    So 36 possibilities for 2 rolls.
    Doesn't take us anywhere.

New direction:
-- If the first roll is odd, then you need another odd on the second one.
-- If the first roll is even, then you need another even on the second one.
This may be the key, right here !

-- The die has 3 odds and 3 evens.

-- Probability of an odd followed by another odd = (1/2) x (1/2) = 1/4
-- Probability of an even followed by another even = (1/2) x (1/2) = 1/4

I'm sure this is it.  I'm a little shaky on how to combine those 2 probs.

Ah hah ! 
Try this:

Probability of either 1 sequence or the other one is (1/4) + (1/4) = 1/2 .

That means ... Regardless of what the first roll is, the probability of
the second roll matching it in oddness or evenness is 1/2 .

So the probability of 2 rolls that sum to an even number is 1/2 = 50% .

Is this reasonable, or sleazy ?

Sellus Evaluate the expression when m=25. m + 2(m-5) = [?]​
stiv31 [10]

Answer:

65

Step-by-step explanation:

So we have the expression:

m+2(m-5)

And we want to evaluate it for m=25.

So, substitute 25 for m:

=(25)+2((25)-5)

Subtract:

=25+2(20)

Multiply:

=25+40

Add:

=65

So, our answer is 65.

And we're done!

Does anyone know the answer to this? I can't understand why it isn't -7.​

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7

Which is greater, |-6.3| or |-19\20|
MrMuchimi
|6.3| because the lines mean absolute value. Take the positive number values of each number and compare them. 6.3 vs 19/20. 19/20 is 0.95 so 6.3 is bigger.
