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:
That is an acute angle
Step-by-step explanation:
Its impossible to give measures without a protractor and with so little information, if you supply me with more I may be able to help you find the measures.
2) vertical angles
vertical angles are always across from each other where two lines cross
angle 6 and angle 8 are also vertical
angle 1 and angle 3 are also vertical
angle 4 and angle 2 are also vertical
hope this helps :)

Answer:
(2,1)
Step-by-step explanation:
The solutions are the points located inside the shaded region. The only point not located in that region is the point (2, 1). Therefore, (2, 1) is not a solution to the system of inequalities.
