First You would rewrite the equation:
M^2-m+3+m-1
Second: rewrite equation to Combine like terms
M^2-m+m+3-1
Answer:
M^2+2
A=number of seats in section A
B=number of seats in section B
C=number of seats in section C
We can suggest this system of equations:
A+B+C=55,000
A=B+C ⇒A-B-C=0
28A+16B+12C=1,158,000
We solve this system of equations by Gauss Method.
1 1 1 55,000
1 -1 -1 0
28 16 12 1,158,000
1 1 1 55,000
0 -2 -2 -55,000 (R₂-R₁)
0 12 16 382,000 (28R₁-R₂)
1 1 1 55,000
0 -2 -2 -55,000
0 0 4 52,000 (6R₂+R₃)
Therefore:
4C=52,000
C=52,000/4
C=13,000
-2B-2(13,000)=-55,000
-2B-26,000=-55,000
-2B=-55,000+26,000
-2B=-29,000
B=-29,000 / -2
B=14,500.
A + 14,500+13,000=55,000
A+27,500=55,000
A=55,000-27,500
A=27,500.
Answer: there are 27,500 seats in section A, 14,500 seats in section B and 13,000 seats in section C.
Answer:
5.wy
6.?
7.?
Step-by-step explanation:
sorry i dont have that book
maybe too the other
They are not equivalent expression because 3^2 is 9 since 3*3 is 9 but 3*2 is 6, so the expressions are not equivalent. <span />
Answer:
d. is the sum of the probabilities of the sample points in the event.
Step-by-step explanation:
Suppose we have a fair coin then the the sample space S is given by {(H), (T)}
the head and tail are the sample points.
the probability of sample space will be given by the sum of probability of head and tail. P(S)= P(A) + P(B)
1= 1/2+ 1/2
The total probability of the sample space always equals 1
The individual probabilities add up to to give the probability of the sample space.
