The ages of members of an online gaming group are normally distributed with a mean of 23 years and a standard deviation of 4 yea

Lelechka [254]

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

suppose that a certain basketball athlete earned $23,000,000 to play 80 games, each last 48 min. how much did the athlete earn p

Anit [1.1K]

He earns 23 000 000 per 80 games for 48min
Per game he earns
$23000000 \div 8 0 = 782500$
If he earns 782 500 per game he earns 5 989,5833 per minute

$782500 \div 48 = 5989.5833$
If he played 2/3 of the time he played 32min which means he earned...

$782500 \div 32 = 24453.125$
So he trained 35hours for a 48min match
Together that is 35.8hours

But I dont think this really matters here you just have to multiply 24453.125 with 60

And you get his hourly salary which is 1 467 187.5
