Answer:
Step-by-step explanation:
A.123.50≤20+10(x)
103.50≤10x
10.35 hours at least to equal the 123.50.
10.35 hours *10 an hour is 103.50+20 flat fee=123.50
B. 123.50≤15(x)
8.24 hours or more. 15.00 an hour at 8.24 hours = 123.60
C. He will work less hours if he charges more and does not charge the flat fee.
Answer:
It is not a Type I error neither a Type II error.
Step-by-step explanation:
Let 
be the true mean match score. The null hypothesis is 
and the alternative hypothesis is 
(upper-tail alternative). When the test shows that the mean match score is more than 80 when actually is equal to 80 a Type I error is made. On the other hand, when the test shows that the mean match score is equal to 80 when actually is more than 80 a type II error is made. Therefore, when the test shows that the mean match score is more than 80 when the person does not actually have a fingerprint match, does not correspond to a Type I error neither to a Type II error.
Answer:
it 100
Step-by-step explanation:
firs take the zero then time with the 5 it would give 10 n
then add the zero so 100
<span>The correct answer to your question is... a rational #, because w</span><span>hen you add two rational #'s, each # can be written as a rational #.
</span><span>
Reasoning:
So, adding two rational #'s like adding fractions will result in another fraction of this same form since integers are closed under + and x. Thus, adding two rational #'s produces another rational #.
By the way # means number.
