Answer:

8 = r

Step-by-step explanation:

69 = 9r -3

Add 3 to each side

69+3 = 9r -3+3

72 = 9r

Divide each side by 9

72 / 9 = 9r/9

8 = r

Hi there
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r)^(-n))÷r]
So we need to solve for pmt (the amount of the annual withdrawals)
PMT=pv÷ [(1-(1+r)^(-n))÷r]
Pv present value 65000
R interest rate 0.055
N time 10 years
PMT=65,000÷((1−(1+0.055)^(
−10))÷(0.055))
=8,623.40....answer

Hope it helps

Answer:

Y' = (-2, 4\frac{2}{3})

Step-by-step explanation:

Given

Y = (-3,7)

Scale\ Factor = (\frac{2}{3}x,\frac{2}{3}y)

Required

Determine Y'

Y' can be solved by multiplying the scale factor by Y

i.e.

Y' = Scale\ Factor * Y

For, the x coordinates.

Y' = \frac{2}{3}x

Where

x = -3

Y' = \frac{2}{3} * -3

Y' = \frac{-6}{3}

Y = -2

For the y coordinates:

Y' = \frac{2}{3}y

Where

y = 7

Y' = \frac{2}{3} * 7

Y' = \frac{14}{3}

Y' = 4\frac{2}{3}

Hence:

Y' = (-2, 4\frac{2}{3})

22% of the customers visiting the suit department of a certain store will purchase a suit, 30% will purchase a shirt and 28% wil
Ulleksa [173]

Answer:

If there are 1000 customers in the store one week, how many will purchase exactly one of these items

1000 CUSTOMERS*28%=280

Step-by-step explanation:

A The event that a persons buys a suit  

B The event that a person buys a shirt  

C The event that a person buys a tie  

 

P(A)=  22%

P(B)=  30%

P(C)=  28%

P(AB)= 11%

P(AC)= 14%

P(BC)= 10%

P(ABC)= 6%

A u B u C Is the event that any item is bougth

AC u AC u BC Is the event that any two events occured

So the wanted probability is

P[(A u B u C )(AB u AC u BC)^c

P[(A u B u C )=P(AB)+ P(BC)+P(BC)

P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06

                      =0,51

0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c

        =0,28

1000 CUSTOMERS*28%=280
