84/4= 21 students/ teacher
21*25= 525 students/ 25 teachers
Answer:
We conclude that:
Yes; Each input has only one output.
Step-by-step explanation:
From the given arrow diagram, we can easily determine the table
x y
2 24
4 8
6 16
8 32
10 32
From the table, it is clear that each input has only one output, in other words, each possible x value is leading to exactly one y value.
Meaning there is no repetition of any domain (x) value.
Therefore, we conclude that:
Yes; Each input has only one output.
Answer:
1 / 1365
Step-by-step explanation:
Given that :
Number of employees to choose from = 15
Number of employees to be chosen = 4
Probability of choosing You, Kyle, Carol and Adam
Recall ;
P(A) = number of required outcome / Total possible outcomes
Number of required outcome = 4C4
Total possible outcomes = 15C4
nCr = n! ÷ (n-r)!r!
Using calculator to save computation time :
15C4 = 1365
4C4 = 1
P(choosing you, Kyle, Carol and Adam) :
1 / 1365
