PVAO=p [(1-(1+I/k)^(-kn) /(I/k)]
P payments 165
I interest rate
K compounded monthly
N time 9

165×((1−(1+0.027÷12)^(−12×14))÷(0.027÷12))
=23,061.76

165×((1−(1+0.029÷12)^(−12×14))÷(0.027÷12))
=24,446.65...correct

165×((1−(1+0.025÷12)^(−12×14))÷(0.027÷12))
=21,637.39

165×((1−(1+0.021÷12)^(−12×14))÷(0.027÷12))
=18,665.68 .....correct

Solve the equation. Write your answer as an integer or simplified fraction.
saw5 [17]

<u>Corrected question :</u>

Solve the equation. Write your answer as an integer or simplified fraction.

  • 8n - 7 (n - 2) = 18

<u>Required Solution :</u>

The given equation,

  • 8n - 7 (n - 2) = 18

★ Multiplying -7 into (n - 2),

>> 8n - 7 × (n - 2) = 18

>> 8n - 7n + 14 = 18

★ On substracting 7n from 8n we gets,

>> n + 14 = 18

★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14),

>> n = 18 - 14

>> n = 14

★ Therefore,

  • Value of n is 14.

sergij07 [2.7K]

Answer:

a) sample size is 40

Step-by-step explanation:

(a)

\sigma=4 minutes

Margin of error, E is 75 seconds E=75/60= 1.25 minutes.

The level of significance \alpha= 0.05 for 95% level of significance

For 95% confidence interval z_{\frac{\alpha}{2}}=1.96 from standard deviation table

Sample size required, n

n=\left (\frac{z_{\frac{\alpha}{2}}\cdot \sigma}{E} \right )^{2}=\left (\frac{1.96\cdot4}{75/60} \right )^{2}=39.337984

Rounding off, n=40

Sample size =40

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.
Law Incorporation [45]

Answer:

Question 1: A)we need to use the CIRCUMFERENCE.

B) Circumference of a Circle  = 2 π R

c)The distance traveled in 1 rotation  =  628 ft

2(a)AREA of a CIRCLE   = π  R²

(b)Area the wheel takes up is 31,400 sq ft

Step-by-step explanation:

Question 1:

Diameter  = 200 ft

Now,as Diameter = 2 x Radius

So, R  = D/2 =200/2 = 100 ft

A) Distance around the wheel = The length of the boundary of the wheel.

So, we need to use the CIRCUMFERENCE.

B) Circumference of a Circle  = 2 π R

Here R = Radius and use π =  3.14

C) The distance traveled in 1 rotation = 1 completer length of  boundary

Now, Circumference  = 2 π R = 2 x (3.14)  x (100 ft)  = 628 ft

Question 2:

A) Space the Ferris Wheel takes up   = Area of the wheel

AREA of a CIRCLE   = π  R²

B) AREA of a CIRCLE   = π  R²

=  (3.14) (100 ft ) (100 ft)  = 31,400 sq ft

So, the area the wheel takes us is 31,400 sq ft
