A sixth number will be added to the list. What must it be in order for the mean to be 12?

Vlad1618 [11]

Answer:

Step-by-step explanation:

7+16+11+12+10= 56

In order to find the 6th number, you must multiply 12 and 6.

12*6= 72

72-56= 16

Double check your work:

7+16+11+12+10+16= 72

72/6= 12

the population of a local species of dragonfly can be found using an infinite geometric series where a1=30 and the common ratio

diamong [38]

The sum of any geometric sequence (if it converges, r^2<1) is of the form:

s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=number of terms...

s(n)=30(1-0.4^n)/(0.6)

s(n)=50(1-0.4^n)

Since r<1 the sum of the infinite series is just:

s=50

Describe the relationship between compound interest and exponential growth

Gennadij [26K]

Answer:

Relationship between compound interest and exponential growth

C.I = $P[(1 + \frac{R}{100})^{n} - 1]$

where, P =Principal

R =Rate of interest, n= Duration i.e time interval for which money has been taken, C.I =Compound Interest

Exponential growth = A $(1+\frac{K}{100})^s$

Where , A=Initial value of population, K= Rate at which population is declining in percentage, s=total time between starting population and final population

Now , If you compare between Exponential growth and compound interest

P→(Replaced by)→A,

R→(Replaced by)→K,

n→(Replaced by)→s,

As C.I is calculated for money, and Exponential word is used for both money as well as increase in population.

So, just replacing keeping the meaning same

C.I = $P[(1 + \frac{R}{100})^{n}]$ - P

→Compound Interest = Exponential growth - Initial Value(either money or any population considered)
