The median for city A is 4 and the median for city B is 5.25.
Answer:
No Real Solutions.
Step-by-step explanation:
√(x-5)=8√(x-2)
Square on both sides,
(√(x-5))^2=(8√(x-2))^2
or,(x-5)=64(x-2)
or,x-5=64x-128
or,-5+128=64x-x
or,123/63=x
Therefore, x=41/21
If you plug x=41/21 in √(x-5)=8√(x-2) you do not get equals, so the problem has no real solutions.
Answer:
Yes, the events silver and black are mutually exclusive.
Step-by-step explanation:
We are given;
the probability that car was mainly white;P(W) = 0.24
the probability that it was mainly silver;P(S) = 0.22
the probability that it was mainly black; P(B) = 0.19
We can say that while a car can certainly be black and silver, a car cannot be mainly silver and mainly black at the same time. This is because one color is going to be dominant. Thus, they cannot happen at the same time. We can therefore conclude that;
Yes, the events silver and black are mutually exclusive.
A) 20.6 x 11.4 : 21 x 11 = 252
6.9 x 3.6 : 7 x 4 = 28
252/28 = 9
b) Each number has been multiplied by 10 so for 4 numbers 9 x 10000 = 90000
