Answer:
0.86
Step-by-step explanation:
The z-score we need to make the comparison is given by
where
= the standard deviation established in the study
n = the sample size
and for the Normal distribution N(0,1) we want to find
<em>P(X > -1.0801)
</em>
By using a spreadsheet or the table attached, we find that
P(X > -1.0801) = 0.86
(See picture attached)
9.3 and were closest to another.
<u><em>Explanation</em></u>
First we will convert each given fractions into decimal form. So....
Then the scores are: 9.30, 9.50, 9.80, 9.95 and 9.25
So, 9.30 and 9.25 are closest to another as their difference is (9.30-9.25)=0.05
That means , 9.3 and were closest to another.
Answer:
-200 isn't higher than 450 but 450 is:
450 is 250 higher than -200
Step-by-step explanation:
Selection A seems appropriate.
It is of the form k*f(x), where f(x) is an exponential function and k > 1.
