A machine has four components, A, B, C, and D, set up in such a manner that all four parts must work for the machine to work pro

olchik [2.2K]

Answer:

0.756

Step-by-step explanation:

It is given that a machine has four components, A, B, C, and D.

$P(A)=P(B)=0.93, P(C)=0.95,P(D)=0.92$

If these components set up in such a manner that all four parts must work for the machine to work properly.

We need to find the probability that the machine works properly. It means we have to find the value of $P(A\cap B\cap C\cap D)$ .

If two events X and Y are independent, then

$P(X\cap Y)=P(X)\times P(Y)$

Assume the probability of one part working does not depend on the functionality of any of the other parts.

$P(A\cap B\cap C\cap D)=P(A)\times P(B)\times P(C)\times P(D)$

Substitute the given values.

$P(A\cap B\cap C\cap D)=0.93\times 0.93\times 0.95\times 0.92$

$P(A\cap B\cap C\cap D)=0.7559226$

$P(A\cap B\cap C\cap D)\approx 0.756$

Therefore, the probability that the machine works properly is 0.756.

An initial investment of $100,000 at 12% interest is compounded weekly (use 52 weeks in a year). What will the investment be wor

ozzi

Answer:

$3644675.9

Step-by-step explanation:

The initial investment is $100000. The interest rate is 12%.

We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.

The weekly interest rate is $\frac{12}{52} = 0.231$ %.

Assuming 1 year equivalent to 52 weeks.

Hence, using the formula of compound interest the final sum will be

$100000(1 + \frac{0.231}{100} )^{(30 \times 52)}$

= $3644675.9 (Approximate)

Joe would be paying $700 in 5 years time.

Explanation:

($2,000)(0.07/year)(5 years)
= ($2,000)(0.07)(5)
= $700
