Answer:
B
Step-by-step explanation:
Answer:
(2,3)
Step-by-step explanation:
The given system is
y=3x-3
y=2x-1
We equate both equations and solve for x.
Group like terms to get:
We put x=2 into y=3x-3 to get:
As an ordered pair the solution is (2,3)
Answer:
If isomorphism exists between two groups, then the identities correspond, i.e. if f:G→G′ is an isomorphism and e,e′ are respectively the identities in G,G′, then f(e)=e′.
The probability that a candidate chosen at random from among these two sets of candidates will have selected questions 1, 2 and 3 is 0.4179.
<h3>How to calculate probability?</h3>
The probability that a candidate chosen at random from among these two sets of candidates will have selected questions 1, 2 and 3 will ba calculated thus:
= [(9C6 /12C9) × 1/2] + [(9C7)/12C10) × 1/2]
= 42/220 + 18/66
= 0.1909 + 0.2727
= 0.4179
In conclusion, the probability is 0.4179.

Answer:
12/99
Step-by-step explanation:
x=0.121212
100x=12.121212
100x-x=12.1212-0.1212
99x=12
x= 12/99
