vova2212 [387]

Answer:

<u>Based on the results the boutique could be located there.</u>

<u>Step-by-step explanation:</u>

Note: The average income (the mean) is calculated by summing the total incomes then divided by the total sample–9.

The mean ù (average income) = $28,000 + $24,000 + $26,000 + $25,000 + $23,000 + $27,000 + $26,000 + $22,000 + $24,000= $225,000/9= $25,000 (which is ≥ $25,000.

Based on the results of the p-value, using the 5% significant level <em>we fail to reject the null hypothesis</em> (ú≥25,000).

Alexandra invested $20,000 in an account paying an interest rate of 6.2%
bazaltina [42]

Answer:

5.1

Step-by-step explanation:

Compounded Annually:

A=P(1+r)^t

A=P(1+r)  

t

 

A=27200\hspace{35px}P=20000\hspace{35px}r=0.062

A=27200P=20000r=0.062

Given values

27200=

27200=

\,\,20000(1+0.062)^{t}

20000(1+0.062)  

t

 

Plug in values

27200=

27200=

\,\,20000(1.062)^{t}

20000(1.062)  

t

 

Add

\frac{27200}{20000}=

20000

27200

​  

=

\,\,\frac{20000(1.062)^{t}}{20000}

20000

20000(1.062)  

t

 

​  

 

Divide by 20000

1.36=

1.36=

\,\,1.062^t

1.062  

t

 

\log\left(1.36\right)=

log(1.36)=

\,\,\log\left(1.062^t\right)

log(1.062  

t

)

Take the log of both sides

\log\left(1.36\right)=

log(1.36)=

\,\,t\log\left(1.062\right)

tlog(1.062)

Bring exponent to the front

\frac{\log\left(1.36\right)}{\log\left(1.062\right)}=

log(1.062)

log(1.36)

​  

=

\,\,\frac{t\log\left(1.062\right)}{\log\left(1.062\right)}

log(1.062)

tlog(1.062)

​  

 

Divide both sides by log(1.062)
