A linear system can have infinite solutions if both systems represent the same line. if a linear system down not represent the same line then it can only have one or no solutions. No solution is if the system is representing parallel lines and one solution represents an intersection of the two lines. in a nonlinear system you can have infinite or up to a maximum of intersections as the highest degree of the systems.
Answer:
0.71 to 2 decimal places.
Step-by-step explanation:
The Probability that a letter A through G is drawn in 1 draw = 7/26.
The probability that a different draw other A-G is made = 1 - 7/26 = 19/26.
Probability ( No A-G drawn in 4 draws) = (19/26)^4 = 0.2852.
Therefore, the probability that A-G is drawn at least once = 1 - 0.2852.
= 0.71 to 2 decimal places.

Answer:
Solution given:
x. 
f. fx
13. 15. 195
14. 42 588
15. x. 15x
16. 10. 160
17. 3. 51
. n=70+x. 
=994+15x
we have
mean=sum/n
14.44=
14.44=
doing crisscrossed multiplication
(70+x)*14.44=994+15x
1010.8+14.44x=994+15x
15x-14.44x=1010.8-994
0.56x=16.8
x=16.8/0.56
x=30
