there are 27 more green cars than black cars in the parking lot. What percentage of the cars in the parking lot are green? What
Yanka [14]

Answer:

Black is 3.57%

Green is 96.43%

Step-by-step explanation:

Since 27 green than black

Let the black car be b

So green cars which 27 more than black means 27b

So to calculate the percentage of green we will have

27b/27b+b ×100

27b/28b ×100

Let's eliminate the b

27/28×100

2700/28

96.43%

So let's calculate for Black

b/27b+b ×100

b/28b ×100

Eliminate b

1/28 ×100

100/28

3.57%

Therefore the percentage for Black is 3.57% and for green is 96.43%

Act scores for the 1,171,460 members of the 2004 high school graduating class who took the test closely followed the normal dist
Alborosie
We can rewrite the asked question like this:
E(X_1-X_2)
wherein X_1 and X_2 are random variable with the same given  normal distribution. Then mean of (X_1-X_2) is zero and the variance 
can be computed like this: 4.8+4.8=9.6
So, the random variable X_1-X_2 follows a normal distribution 
with means 0 and standard deviation 9.6. 
The median of the law N(0,9.6) is 0. 
So the expected difference of the score is 0.
