If 22000 is invested at 12% interest compounded quarterly, find the interest earned in 12 years.

Answers

Answer:

Interest earned in 12 years = 57178

Step-by-step explanation:

$A=P(1+rn)n⋅t$

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

then

P=22000 , r=12% , n=12 and t=12 years

putting these value

$A=22000(1+0.12/12) 12⋅8$

= 22000(2.5992729255593856)

= 57178

MathematicalUse Number Sense Duane and Mick are savingtheir money to build a tree house. Duane adds $5 to their piggybank every other week. Mick adds $2 every week. So far they havesaved $45. How many weeks have they been saving their money?

Answers

assuming they start saving at 0 dollars

45=total=duanesavings+micksavings
duanesavings=confusing, I will explain
mick savings =amount saves per week times number of weeks

duane saves 5 dollars every other week, aka 2.5 dollars per 1 week
DS=2.5w
MS=2w

since they save at same time and at that week, when the weeks are equal (w=w), 45 it total

DS+MS=45
2.5w+2w=45
4.5w=45
divide by 4.5 both sides
w=10

10 weeks

What is the answer to the equation7/8(x - 1/2)=-49/80

Sajia has 30 Books in her library. she sold 9 books at the thrift store on Saturday. Write and solve and inequality to determine how many more books she can sell if she comes back on sunday?

Answers

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is $9 + x \leq 30$

Solution:

Given that Sajia has 30 Books in her library

She sold 9 books at the thrift store on Saturday

To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday

Let "x" be the number of more books she can sell if she comes back on sunday

We can write a inequality as:

$\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }$

$9 + x \leq 30$

Now moving 9 from L.H.S to R.H.S we get,

$x \leq 30 - 9$

On solving 30 - 9 = 21,

$x \leq 21$

So Sajia can sell 21 books she can sell if she comes back on sunday

What's different with census and sample?

Answers

A census is a study of every unit, everyone or everything, in a population. It is known as a complete enumeration, which means a complete count. A sample is a subset of units in a population, selected to represent all units in a population of interest.

I know when you do a census, you cover the entire population but when you take a sample, you select a group from the population. There can be only one census but there can be many different samples from the same population. Hence, the latter results in sampling error (because it is just one aspect of the population)
