<span>A) 4x − 2y − z = −5
B) x − 3y + 2z = 3
C) 3x + y − 2z = −5
Looking at ALL 4 solutions, x =0 in all of them.
So, let's say x = 0, eliminate the "x's" and just keep equations B and C
</span>
<span>B) -3y + 2z = 3
C) y − 2z = −5
</span>Add B) and C)
-2 y = -2
y = 1
<span>1 − 2z = −5
</span>-2z = -6
z = 3
and x = 0
Answer:
0.40951
Step-by-step explanation:
P(none in five years) = 1 - 0.1 = 0.9
P(at least one) = 1 - P(none in five years)
= 1 - 
= 1 - 0.59049
= 0.40951
So the probability of a hurricane hit at least once in the next 5 years is 0.40951
Answer:Tony's gross salary for the week is $2352.2
Step-by-step explanation:
Tony works has a salesclerk in a department store. He earns a base salary of $215 per week plus 15% commission on his weekly total sales. The total sales for last week was $ 14,250.00. It means that his commission would

Therefore, Tony's gross salary for the week would be
215 + 2137.5 = $2352.2
