Answer:
RS = 4.8
OT = 3.6
From the Pythagorean Theorem we know:
OR^2 = ST^2 + OT^2
OR^2 = 4.8^2 + 3.6^2
OR ^2 = 23.04 + 12.96
OR^2 = 36
OR = 6
Step-by-step explanation:
Answer:
The total number of ways are 168.
Step-by-step explanation:
Consider the provided information.
There are 7 junior and 3 senior coders in her group.
The first project can be written by any of the coders. The second project must be written by a senior person and the third project must be written by a junior person.
For second project we have 3 choices and for third project we have 7 choices.
Now there are 2 possible case:
Case I: If first and second coder is senior, then the total number of ways are:

Case II: If first and third coder is junior, then the total number of ways are:

Hence, the total number of ways are: 42+126=168
The percent of change is 73.33 percent
