Her total amount of pencils is b+y
Answer:
The statement in the question is wrong. The series actually diverges.
Step-by-step explanation:
We compute
Therefore, by the series divergence test, the series 
diverges.
EDIT: To VectorFundament120, if 
is a sequence, both 
and 
are common notation for its limit. The former is not wrong but I have switched to the latter if that helps.
Answer:
z-score = 1
Step-by-step explanation:
Given
Mean= μ=240
SD= σ=32
In order to find the z-score of a value, the mean is subtracted from the value and then divided by standard deviation.
The formula for z-score is:
z-score=(x-μ)/σ
Here x is the value whose z-score is to be found.
In the given question, x = 272
So,
z-score=(272-240)/32
=32/32
=1
So , the z-score for 272 is 1..
-6+3-3(-18)
Okay.
Work from left to right.
-6 plus 3 equals -3.
(Think of it as in a number line, from the spot of -6, move right three units. This will give you -3. Anyways..)
Now you have -3-3
The result is -6.
-6(-18)
Negative six times negative eighteen equals positive 108.
The answer is 108.
