Answer:
0(no real solutions)
Step-by-step explanation:
1) write the equation
8n^2-n=-12
1) bring "-12" to left to factor
8n^2-n+12
2) multiply 12 and 8
12*8=96
So what*what=96
But what+what=1
Nothing, there are no real solutions
Answer:
And we can find this probability with this difference:
Step-by-step explanation:
Let X the random variable that represent the temperatures of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And using the z score formula given by:
And using this formula we got:
And we can find this probability with this difference:
We know that our function is
; the only thing we need to find
is replace
with
in our original function:
Now, lets simplify our function:
After simplify our function, we can conclude that
the two consecutive numbers are 56 and 57
x+x+1=113
2x+1=113
2x=113-1
2x=112
x=112/2
x=56
therefore, x=56
x+1= 56+1= 57
