Hello,
Answer B
2x+y=6 (1)
-4x+3y=8 (2)
2*(1)+(2)==>5y=20==>y=4
==>2x=6-4==>2x=2==>x=1
30% of the chairs are red. 75/250 x x/100
Answer:
Step-by-step explanation:
Given that twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006).
considering the total number of vehicles, probability for a randomly drawn vehicle not covered by insurance = 0.23
Each vehicle can be treated as independent of the other
Hence X no of vehicles not covered by insurance is Binom with n = 35 and p - 0.23
a) the expected number of these automobiles that are not covered by insurance=E(x) =

b) the variance
=
Std dev = square root of variance = 2.4897
40% of the apples are not right. Since only 3/5 are right, the that would leave 2/5 to not be right. Since 2/5=40/100, then the answer is 40%. That's just the eay I remember it, hope this helps
All you have to do is just bring the numbers that are not zero from each digit.
so in this process, the answer you would get is 724,562.
I hope this helped
