Multiply by 10^3=1000
You get:
-625y-184=2506y
The correct answer is C) both a and b.
A probability distribution shows all of the possible values of the experiment and the probabilities that go with them.
To get the number of members between 15 years and 30 years we proceed as follows:
z=(x-μ)/σ
where:
mean,μ=23
standard deviation, σ=4 years
thus
P(15<x<31)
when x=15
P(x<15)
z=(15-23)/4
z=-2
thus
P(x<15)=P(z<-2)=0.0228
when x=31
z=(31-23)/4
z=2
thus
P(x<31)=P(z<2)=0.9772
Hence:
P(15<x<31)=0.9544
hence the number of members between that age was:
0.9544×300
=286.32 people
~285 People
Answer: 285 people
Answer:
5
Step-by-step explanation:
2320 - 195 = 2125
2125/425 = 5
Step-by-step explanation:
I'm not sure where a is supposed to be in this equation, but I'm going to assume it's supposed to be written as either 3a x 4b = 54, or 304b = 54a. If it's something else, let me know, but I'll just answer these two for now.
1. 3a x 4b
So we know that b is equal to 9. Therefore, we can rewrite

as

To get rid of a multiplier on one side, divide both sides by the number you want gone. I'll use 4(9), which equals 36.

Then we can divide by 3 to get

0.5 isn't a viable answer, so I'll try the second interpretation.
2. 304b = 54a
This one is a bit easier. All we need to do is divide both sides by 54 to get

304 x 9 = 2736
2736/54 = 50.66...
Again, not a viable answer. Please edit your question to include a and I'll give it another shot!
