Answer:

Step-by-step explanation:

Using the recursive formula with a₁ = k , then

a₂ = 2a₁ = 2k

a₃ = 2a₂ = 2(2k) = 4k

balu736 [363]

Answer:

y = 3 - 4x

To find the y intercept let x = 0

y = 3 - 4(0)

y = 3 or ( 0 ,3)

Hope this helps.

Y is a random variable that is distributed N(-16, 1.21). Find k such that Prob(-15.043 < Y ≤ k) = 0.1546. (Round your answer

IgorLugansk [536]

Transform Y to Z, which is distributed N(0, 1), using the formula

Y = µ + σZ

where µ = -16 and σ = 1.21.

Pr[-15.043 < Y ≤ k] = 0.1546

Pr[(-15.043 + 16)/1.21 < (Y + 16)/1.21 ≤ (k + 16)/1.21] = 0.1546

Pr[0.791 < Z ≤ (k + 16)/1.21] ≈ 0.1546

Pr[Z ≤ (k + 16)/1.21] - Pr[Z < 0.791] = 0.1546

Pr[Z ≤ (k + 16)/1.21] = 0.1546 + Pr[Z < 0.791]

Pr[Z ≤ (k + 16)/1.21] ≈ 0.1546 + 0.786

Pr[Z ≤ (k + 16)/1.21] ≈ 0.940

Take the inverse CDF of both sides (Φ(x) denotes the CDF itself):

(k + 16)/1.21 ≈ Φ⁻¹ (0.940) ≈ 1.556

Solve for k :

k + 16 = 1.21 • 1.556

k ≈ -14.118

Suppose you are given that p = 2q+1 and that p = 8.

iVinArrow [24]

Answer:

We conclude that the following statements can be proved such as:

$2q+1 = 8$

Step-by-step explanation:

Given the expression

$p = 2q+1$

Given

$p = 8$

IF WE SUBSTITUTE p=2q+1 in p=8

Now, substituting p = 2q+1 in the expression p=8

$p = 8$

$2q+1 = 8$ ∵ p = 2q+1

Therefore, we conclude that the following statements can be proved such as:

$2q+1 = 8$
