Answer:
y^2(y^4)=y^6
(2y)^2=4y^2
(y/4)^2=y^2/16
2(y^3)^3=2y^9
Step-by-step explanation:
Answer:
Paired samples t- test is appropriate for Dean's hypothesis
Step-by-step explanation:
Given Data :
Student 1 2 3 4 5 6 7 8
Marketing 82 86 74 93 90 76 87 100
Finance 76 91 70 79 96 70 85 81
We are supposed to find the test which is appropriate for Dean's hypothesis
We are given the grades of two different subjects for same student
We perform the paired t test because the final grades for the Marketing and Finance is taken for the same student.
So, Option B is correct
Hence Paired samples t- test is appropriate for Dean's hypothesis
Answer:
<h2>
A. 1 and 1
</h2><h2>
D. 6 and 1/6
</h2><h2>
E -4/7 and -7/4</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Which pairs of numbers represent a number and its reciprocal?
A. 1 and 1
B. 2/3 and -3/2
C. 1/2 and 5
D. 6 and 1/6
E -4/7 and -7/4
Reciprocal of a number is simply 1 divided by such number. For example the reciprocal of a is 1/a where is any number.
Based on the definition, the following pair of numbers represent a number and its reciprocal
1 and 1
The reciprocal of 1 is 1/1 which is equal to 1
6 and 1/6;
Since I can divide 1 by 6 to get 1/6 , this means that 1/6 is the reciprocal of 6. The pair 6 and 1/6 therefore represent a number and its reciprocal.
-4/7 and -7/4
reciprocal of -4/7 will be 1/(-4/7) = 1 * 7/-4 = -7/4. This shows that -7/4 is the reciprocal of -4/7 hence -4/7 and -7/4 represents a number and its reciprocal.
