Answer:
0.1056 = 10.56% probability that the concentration exceeds 0.60
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability that the concentration exceeds 0.60?
This is 1 subtracted by the pvalue of Z when X = 0.6. So
has a pvalue of 0.8944
1 - 0.8944 = 0.1056
0.1056 = 10.56% probability that the concentration exceeds 0.60
Answer: C.
Step-by-step explanation: y=mx+b
y=-3/4xx+5
<span>Actually, every square is a rectangle, since the angles in a square
are always right angles. That's more than saying that a square can be
a rectangle; it is one.
</span><span>
And since squares are rectangles, you know that some rectangles are
squares--namely, the squares are!
</span>
<span>We teach children "this is a
rectangle, that is a square. The rectangle's sides are different
lengths". But when you grow up, it's important to think of the square
as a SPECIAL rectangle, because it is all that a rectangle is, and
more.
</span>
A square is still a rectangle, but it's not just a rectangle, it's a (pedigreed) square.
In summary, yes a rectangle can be a square.
Hope this helped :)
Jared is correct. 10 stands for y, which needs to be tested by the other y factor on the other side, thus making this equation possible.
