Using error concepts, it is found that the option that represents a Type I error is:
- d. Saying that the student is a music industry management major when in fact the student is a finance major.
The definitions of each type of error are as follows:
- A Type I error happens when a <u>true null hypothesis is rejected.</u>
- A Type II error happens when a <u>false null hypothesis is not-rejected.</u>
In this problem, the Hypothesis are:
- Null: Student is a finance major.
- Alternative: Student is a music industry management major.
By the definition of a Type I error, in this problem, it would consist in saying that a finance major student is a music industry management major student, hence option d is correct.

Each of the linear factors occurs precisely once, so the sign of the given rational expression will change at each of the points where one of the linear factors is zero. That is at:
x
=
−
3
,
−
1
,
2
,
4
Note that when
x
is large, the
x
2
terms will dominate the values of the numerator and denominator, making both positive.
Hence the sign of the value of the rational expression in each of the intervals
(
−
∞

and
(

follows the pattern

. Hence the intervals

and
(

)
are both part of the solution set.
When
x
=
−
1
or
x
=
4
, the denominator is zero so the rational expression is undefined. Since the numerator is non-zero at those values, the function will have vertical asymptotes at those points (and not satisfy the inequality).
When
x
=
−
3
or
x
=
2
, the numerator is zero and the denominator is non-zero. So the function will be zero and satisfy the inequality at those points.
Hence the solution is:

Answer:
60%
Step-by-step explanation:
24/40 is 3/5
3 divide by 5 is 0.6
0.6 is 60%
In order to get the answer for this question you need to times 2 by 10, which equals 20 since it's $2 for each guest. That now leaves her with $20. $26+$20 <u>equals </u><u>$46</u> for the total cost of the retirement party.
