Answer:
approx 193200
Step-by-step explanation:
As known for normal distribution is correct the rule 95.4% of the results are situation within mean+-2*s ( where s is a standard deviation)
So the border is 100+-2*15=70 and that is approx=67.
95.4% of 84000000 citizens are= 8 400 000*0.954=8013600 persons
So the residual number of the citizens =8400000-8013600=386400 citizens
Because of the simmetry of normal distribution to find the number of the citizens that have IQ below 67 we have to divide 386400 by 2.
N=386000/2=193200

Answer: He will have $1721.28. after 4 years.
Step-by-step explanation:
The formula we use to find the compounded amount A is :
, where P= principal value, r = rate of interest , t= time.
As per given , we have
P=$1500 , r=3.5%=0.035 , t= 4 years
Money he will have after 4 years = 

Hence, he will have $1721.28. after 4 years.
It’s gonna be radical 10x/ 4x.
