I believe that is the commutative property...which basically states that u can move the numbers around and it will not change the result
Answer:
A. -1.6; not significant
Step-by-step explanation:
The z-score of a data set that is normally distributed with a mean of
and a standard deviation of
, is given by:
.
From the question, the test score is:
, the mean is
, and the standard deviation is
.
We just have to plug these values into the above formula to obtain:
.
This simplifies to:
.
.
We can see that the z-score falls within two standard deviations of the mean.
Since
the value is not significant.
The correct answer is A. -1.6; not significant
In order to solve this we need to know the quantity of the 18 inch pizza eaten and the fraction of the minute in which it was eaten.
The graph displays y = -2x + 1
So, f(-1) would be:
f(-1) = -2(-1) + 1
= 2 + 1
f(-1) = 3
Y = 0.5 x X I think that is all you do?
