Answer:
She did not qualify the exam.
Step-by-step explanation:
Given data
Total no of question in a test = 20
No. of question answered correctly = 16
Percentage of question answered correctly

But in order to get in the exam the student must have to score at least 90 %. But she got only 80 % so she did not qualify the exam.
20 and 45x
We look for a number that can go into both numbers.
5 into 20 is 4 and 5 into 45x is 9x.
5: 20 45x
4 9x
So no other number can go into 4 and 9x again.
So the GCF of 20 and 45x is 5.
Hope this explains it.
Answer:
3
Step-by-step explanation:
Answer:
C: p < 0.01
Step-by-step explanation:
We are given;
Spearman rank Correlation Coefficient: rs = 0.53
sample size: n = 13 pairs
Now, from the table attached, tracing n = 13 and locating a corresponding value of rs = 0.53 which falls in between 0.484 and 0.56. Thus, we can see that p is greater than the nominal significance value of 0.05 but less than 0.01.
Thus, correct answer is p < 0.01
