Answer: 23498.935

Step-by-step explanation:

this helped me in middle school so please remember this equation

A=P(1+R/N)NT

A=AMOUNT

P=PRINCIPAL

R=INTEREST RATE

N=NUMBERS OF TIMES THE INTEREST IS COMPOUNDED

NT=TIME(YEARS

So now we have this... right...

A=P(1+R/N)NT

you have to fill it in and you will get

a=22,150(1+3/1)^2

put that in your handy dandy calculator and you will get your answer

Answer:

$\large\boxed{\bold{Q1}\ -\dfrac{128}{9}}\\\boxed{\bold{Q2}\ 2^{25}}$

Step-by-step explanation:

$\bold{Q1}\\\\\dfrac{-2(3^2\cdot3^3)^2}{3^{12}\cdot2^{-6}}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=-\dfrac{2(3^{2+3})^2}{3^{12}\cdot2^{-6}}=-\dfrac{2(3^5)^2}{3^{12}\cdot2^{-6}}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=-\dfrac{2\cdot3^{5\cdot2}}{3^{12}\cdot2^{-6}}=-\dfrac{2\cdot3^{10}}{3^{12}\cdot2^{-6}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=-2^{1-(-6)}\cdot3^{10-12}=-2^{7}\cdot3^{-2}\qquad\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=-2^7\cdot\dfrac{1}{3^2}=-\dfrac{2^7}{3^2}=-\dfrac{128}{9}$

$\bold{Q2}\\\\\dfrac{4^2}{4^{-7}}\cdot(2^4\cdot2^3)\cdot(3^{-2})^0\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m},\ a^n\cdot a^m=a^{n+m},\ a^0=1\\\\=4^{2-(-7)}\cdot2^{4+3}\cdot1=4^{9}\cdot2^7=(2^2)^{9}\cdot2^7\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=2^{2\cdot9}\cdot2^7=2^{18}\cdot2^7\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=2^{18+7}=2^{25}$

1.Your primary job’s gross income is $3,500.00/month, and your second job’s realized income is $368.49/month. Deductions are FIC

bazaltina [42]

Part 1
Total income per month = $3,500+$368.49 = $3,868.49
Total deductions = 7.65%+10.75%+8.35% = 26.75% = 0.2675

Net income = Total income - Deductions = Total deductions (1-0.2675) = $3,868.49 (1-0.2675) = $2,833.67

Part 2
Fixed expenses = $1,035.65 which is 36% of realized income.

Then, if realized income is 100%;
$1,035.65 ------------------ 36%
$ Realized income ----- 100%
Therefore,
Realized income = 1,035.65*100/36 = $2,876.81

We are given the following in the question:

Sample size, n = 148

Number of people who sleep for 8 hours or longer, x = 58

$\hat{p} = \dfrac{x}{n} = \dfrac{58}{148} = 0.3918$
