A company is divided into 50,000 shares. An investor purchases 1,000 shares. What percent of the company does the investor own?
AnnZ [28]

Answer:

Step-by-step explanation:

percentage is per 100.

If we have to find x as percentage of y then

formula for percentage is given by = x/y*100

_______________________________________________

Given

total no. of shares = 50,000

Share bought by investor = 1,000

Percentage of share bought by investor

= Share bought by investor/total no. of shares *100

= (1000/50000)*100 = 2%.

It means that if  there are 100 shares for company then investor owns 2 shares of the company. This makes the qualitative analysis easy.

2% percent of the company does the investor own.

What is the probability that five randomly selected students will have a mean score that is greater than the mean achieved by th
katrin2010 [14]

Answer:

the probability that five randomly selected students will have a mean score that is greater than the mean achieved by the students = 0.0096

Step-by-step explanation:

From the five randomly selected students ; 160, 175, 163, 149, 153

mean average of the students = 160+175+163+149+153/5

= mean = x-bar = 800/5

mean x-bar = 160

from probability distribution, P(x-bar > 160) = P[ x-bar - miu / SD > 160 -150.8 /3.94]

P( Z>2.34) = from normal Z-distribution table

= 0.0096419

= 0.0096

hence the probability that five randomly selected students will have a mean score that is greater than the mean achieved by the students = 0.0096

where SD = standard deviation = 3.94 and Miu = 150.8
