For all 3 questions, we will use the section formula.

1) \left(\frac{(4)(2)+(3)(-5)}{7}, \frac{(4)(6)+(3)(-8)}{7} \right)=\boxed{(-1, 0)}

2) \left(\frac{(2)(4)+(3)(-6)}{5}, \frac{(2)(6)+(3)(1)}{5} \right)=\boxed{(-2, 3)}

3) \left(\frac{(1)(5)+(5)(-1)}{6}, \frac{(1)(-6)+(5)(6)}{6} \right)=\boxed{(0, 4)}

Answer:

Variance Σ i=1 (1 - Pi) /Pi^2

Expected value= π(1/1 + 1/2 .......... 1/n) = π.Hn

Step-by-step explanation:

From the information given, we can get

E(T) = E(t1) + E(t2) ......... +E(tn)

1/P1 + 1/P2.......... 1/Pn

-π/r + π/ r-1 +........... π/1

π(1/1 + 1/2 .......... 1/n)

To find the variance,

Variance= var (x1 + x2......... +xr)

E i=1 var (Xi)

Where,

x1, x2, x3 ........... are all independent of each other.

In case of xi : var (xi) = E(xi^2) - E(xi^2)

Probability of the ith term of coupon that would be observed

Pi = (n - i - 1)/n

Therefore,

i-1 coupons out of a total of n coupons.

To calculate Exi, probability Pi

The expected number of coupons required should be = 1

In probability, 1 - Pi expected number of coupons required E (Xi +1)

E(Xi) = Pi + (1- Pi) E(xi + 1)

E(Xi) = 1/Pi

Due to the above,

E(Xi)^2= Pi + (1- Pi) E(xi + 1)^2

E(Xi)^2= Pi + (1- Pi) E(xi^2 + 1 + 2xi)

E(Xi)^2= 2/Pi^2 - 1/Pi

Var (Xi) = 2/Pi^2 - 1/Pi - 1/Pi^2

= (1 - Pi) /Pi^2

Variance Σ i=1 (1 - Pi) /Pi^2

Indicate whether the lines are parallel, perpendicular, or neither. Justify your answer.
sveticcg [70]
Note that when two lines have slopes of m₁ and m₂, then
(i) If m₁ = m₂, then the lines are parallel.
(ii) If m₁*m₂ = -1, then the lines are perpendicular.

Let us evaluate the given lines.
a. y = 4x - 1 and 12x = 3y + 7
    y = 4x - 1  => m₁ = 4
    Write the second equation in standard form.
    3y = 12x - 7
      y = 4x - 7/3 => m₂ = 4.
    m₁ = m₂.
    Answer: PARALLEL

b. x - 7y = 10 and 2x + 14y = 21
   In standard form,
   7y = x - 10 or y = (1/7)x - 10/7      => m₁ = 1/7
   14y = - 2x + 21  or y = -1/7 + 3/2  => m₂ = -1/7
   m₁ ≠ m₂ and m₁*m₂ ≠ -1.
   Answer: NEITHER

c. 5x + 6y = 18 and 18x - 15y = 36
    In standard form,
    6y = -5x + 18 or  y = -(5/6)x + 3     => m₁ = -5/6
    15y = 18x - 36 or y = (6/5)x - 12/5  => m₂ = 6/5
    m₁*m₂ = -1
    Answer: PERPENDICULAR

d. x =1 and y = 1
    x = 1 => m₁ is undefined
    y = 1  => m₂ = 0
    m₁ ≠ m₂ and m₁*m₂ ≠ -1
   Answer: NEITHER

$3,250 is withdrawn at the end of every month from an account paying 4.1% compounded monthly. Determine the previous value of th
kirill [66]
The amount needed such that when it comes time for retirement is $2,296,305. This problem solved using the future value of an annuity formula by calculating the sum of a series payment through a specific amount of time. The formula of the future value of an annuity is FV = C*(((1+i)^n - 1)/i), where FV is the future value, C is the payment for each period, n is the period of time, and i is the interest rate. The interest rate used in the calculation is 4.1%/12 and the period of time used in the calculation is 30*12 because the basis of the return is a monthly payment.

FV = $3,250*(((1+(4.1%/12)^(30*12)-1)/(4.1%/12))
