An internet startup launched a new website last month. They already have 3000 users, and the site has been growing by 17% each week. If this growth continues: a) Write an equation for
N
, the number of users,
t
weeks from now.

An equation for  N , the number of users, t  weeks from now is

Step-by-step explanation:

An internet startup launched a new website last month.

Initial number of users = 3000

We are given that the site has been growing by 17% each week.

Formula:

Where N(t)= Number of users after t weeks

= initial population =3000

r = rate of growth = 17% = 0.17

t = No. of weeks

Substitute the values in the formula :

So,an equation for  N , the number of users, t  weeks from now =

Hence an equation for  N , the number of users, t  weeks from now is

f

step-by-step explanation:

f

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
