Answer:
6:05 PM
Step-by-step explanation:
There are 10 seniors in the class, from which 4 should be chosen by the teacher. The order of the chosen students does not matter. This means that we speak of combinations. THe equation for calculating the number of possible combinations is:
C=N!/R!(N-R), where N is the total number of objects and R is the number of objects we select from the N
In our case, N=10, R=4.
C= 10!/4!*6!=10*9*8*7*6!/6!*4*3*2*1=<span>10*9*8*7/24=5040/24=210
There are 210 different ways for the teacher to choose 4 seniors in no particular order.</span>
Answer:
95⁰
Step-by-step explanation:
next time you want to figure this out, here's how
- they are supplementary angles, so you just subtract 45⁰ from 180⁰
180-45=95
so, you would get the answer 95⁰
for next time, you might not have as much information as you do in this equation so be careful
hope this helps!
