A certain shop repairs both audio and video components. Let A denote the event that the next

alexdok [17]

Answer:

0.12 is the required probability.

Step-by-step explanation:

We are given the following in the question:

A: next component brought in for repair is an audio component

B: event that the next component is a compact disc player

$B \in A$

$P(A)= 0.6\\P(B) =0.05$

We have to evaluate:

$P(B|A) = \dfrac{P(B\cap A)}{P(A)}\\P(B|A) = \dfrac{P(B)}{P(A)}\\\\P(B|A) = \dfrac{0.05}{0.6} = 0.12$

0.12 is the required probability.

John takes out a loan for $ 10 , 000 at a simple interest rate of 5 % to be paid back in 36 monthly installments.

andrew-mc [135]

The monthly principal and interest payment John will pay monthly is $3,750.04

<h3>What is the amount of principal and interest repayment?</h3><h3 />

Given:

P = 10,000
i = 5% / (12 months) = 0.375
L = 36 months

$M = 10000 \times \frac{0.375}{ {1 - (1 + 0.375)}^{ - 36} }$

$M = 10000 \times \frac{0.375}{ {1 - (1.375)}^{ - 36} }$

$M = 10000 \times \frac{0.375}{ {1 - (0.00001049791)} }$

$M = 10000 \times \frac{0.375}{ 0.99998950208 }$

$M = 10000 \times 0.37500393675$

$M = 3750.03936758$

Approximately,

M = $3,750.04

Therefore, John will be be repaying $3,750.04 monthly including principal and interest

Solve the system of linear equations by elimination. <br> 9x−2y=34 <br> 5x+2y=−6

slava [35]

Answer:

x = 2

y = -8

Step-by-step explanation:

9x−2y=34 -------------------(I)

5x+2y=−6 -------------------(II)

Add equation (I) & (II) and so y will be eliminated and we could find the value of x.

(I) 9x - 2y = 34

(II) <u>5x + 2y = -6</u> {add}

14x = 28

x = 28/14

x = 2

Plug in x = 2 in equation (I)

9*2 - 2y = 34

18 - 2y = 34

-2y = 34 - 18

-2y = 16

y = 16/-2

y = -8
