You deposit $2000 each year into an account earning 7% interest compounded annually. How much will you have in the account in 30

SVETLANKA909090 [29]

The amount that will be in the account after 30 years is $188,921.57.

<h3>How much would be in the account after 30 years?</h3>

When an amount is compounded annually, it means that once a year, the amount invested and the interest already accrued increases in value. Compound interest leads to a higher value of deposit when compared with simple interest, where only the amount deposited increases in value once a year.

The formula that can be used to determine the future value of the deposit in 30 years is : annuity factor x yearly deposit

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate
n = number of years

$2000 x [{(1.07^30) - 1} / 0.07] = $188,921.57

If 3t-7=5t, then 6t#

Inessa05 [86]

Here, 3t - 7 = 5t
5t - 3t = -7
2t = -7
t = -7/2

Then, 6t = 6(-7/2) = 3(-7) = -21

In short, Your Answer would be -21

Hope this helps!

Answer:

see below

Step-by-step explanation:

a) median : re-arranged the numbers in order. i.e. min to max

gold: 147 , 147 , 175 , 206 , 212 , 227 , 263 , 275 , 440 , 1022

212 + 227 = 219.50

2

silver: 147 , 163 , 165 , 170 , 178 , 241 , 295 , 313 , 357 , 794

178 + 241 = 209.50

2

bronze: 151 , 169 , 179 , 187 , 193 , 260 , 289 , 325 , 349 , 704

193 + 260 = 226.50

2

b) mean : sum of all numbers divide by n, where n=10

gold: = (147 , 147 , 175 , 206 , 212 , 227 , 263 , 275 , 440 , 1022 ) / 10

= 311.40

silver: = (147 , 163 , 165 , 170 , 178 , 241 , 295 , 313 , 357 , 794 ) / 10

= 282.30

bronze: = (151 , 169 , 179 , 187 , 193 , 260 , 289 , 325 , 349 , 704 ) / 10

= 280.60

c) standard deviation on population (STDEV.P)

Australia = 16.44

china = 33.03

france = 19.74

germany = 30.21

great britain = 13.89

hungary = 12.04

italy = 11.44

soviet union = 48.46

sweden = 13.47

united states = 133.84
