why do most object-oriented programming languages mandate that i/o operations involving secondary storage such as disk are to be done in a try and catch block?

Answer:

In the case of the production Line, we know that,

No of gasoline cans = 5

probability that 1st can is out of tolerance = 0.03

probability that 2nd can is out of tolerance = 0.03

.

.

probability that the 5th can is out of tolerance = 0.03

Therefore,

probability of 1st can out of tolerance + probability of 1st can not out of tolerance = 1

Probability of 1st can not out of tolerance = 1 -- 0.03 = 0.97

probability of 2nd can not out of tolerance = 0.97

.

.

probability of 5th can not out of tolerance = 0.97

Question A:

Probability that they are all out of tolerance

= P(1st can out of tolerance) * P(2nd can out of tolerance) * P(3rd can out of tolerance) * P(4th can out of tolerance) * P(5th can out of tolerance)  

= (0.03 ) * (0.03) * (0.03) * (0.03) * (0.03) =  2.43 E⁻⁸   (2.43 ˣ 10⁻⁸)

Question B:

Probability that exactly two are out of tolerance

= P(1st can is out of tolerance) * P(2nd can is out of tolerance) * P(3rd can is not out of tolerance) * P(4th can is not out of tolerance) * P(5th can is not out of tolerance)

= (0.03) * (0.03) * (0.97) * (0.97) * (0.97) = 0.0008214057

Explanation:

Answer:

Answer is explained in the explanation section below.

Explanation:

Solution:

Note: This question is incomplete and lacks necessary data to solve. But I have found the similar question on the internet. So, I will be using the data from that question to solve this question for the sack of concept and understanding.

Data Given:

x = 27 , 44 , 32 , 47, 23 , 40, 34, 52

y = 30, 19,  24,  13 , 29,  19,  21,  14

It is given that,

∑x = 299

∑y = 167

∑\(x^{2}\) = 11887

∑\(y^{2}\) = 3773

We are asked to verify the above values manually in this question.

So,

1. ∑x = 299

Let's verify it:

∑x = 27 + 44 + 32 + 47 + 23 + 40 + 34 + 52

∑x = 299

Yes, it is equal to the given value. Hence, verified.

2. ∑y = 167

Let's verify it:

∑y = 30 + 19 +  24 + 13 + 29 + 19 +  21 +  14

∑y = 169

No, it is not equal to the given value.

3. ∑\(x^{2}\) = 11887

Let's verify it:

For this to find,  first we need to square all the value of x individually and then add them together to verify.

∑\(x^{2}\) = \(27^{2}\) + \(44^{2}\) + \(32^{2}\) + \(47^{2}\) + \(23^{2}\) + \(40^{2}\) + \(34^{2}\) + \(52^{2}\)

∑\(x^{2}\) = 11,887

Yes, it is equal to the given value. Hence, verified.

4. ∑\(y^{2}\) = 3773

Let's verify it:

Again, for this we need to find the squares of all the y values and then add them together to verify it.

∑\(y^{2}\) = \(30^{2}\) + \(19^{2}\) +  \(24^{2}\) + \(13^{2}\) + \(29^{2}\) + \(19^{2}\) +  \(21^{2}\) +  \(14^{2}\)

∑\(y^{2}\)  = 3,845

No, it is not equal to the given value.

Answer:

P=11 kW

Explanation:

Given that

Number of poles= 8

I.E.C. 180L motor frame

From data book , for 8 poles motor at 50 Hz

Speed = 730 rpm

Power factor = 0.75

Efficiency at 100 % load= 89.3 %

Efficiency at 50 % load= 89.1 %

Output power = 11 kW

Therefore the rated output power of 8 poles motor will be 11 kW. Thus the answer will be 11 kW.

P=11 kW

The power of the old car is half that of the new car. Therefore, the correct alternative is "The new car has more power than the old one."

A) If the moments of inertia of a disk and a cylinder are I1 and I 2 respectively, then the moment of inertia of the disk-cylinder system is 11+12. (True or False)This statement is false. According to the parallel axis theorem, the moment of inertia of the disk-cylinder system is I1 + I2 and not 11 + 12.B) An old model of car changes speed from 0 to 2v in a time interval Δt. A new sports car changes from 0 to v in the same period. Compare the power of the two cars. Consider that both cars have a similar mass.The formula for power is given by P = W/t, where P is the power, W is the work, and t is the time taken. We can assume that the mass of both cars is m.Both the cars have similar masses, but they have different velocities. The work done is given by W = (1/2)mv^2, where m is the mass, and v is the velocity.Substituting the values of W, and t into the formula for power, we have:P1 = W/Δt1 = (1/2)mv^2/Δt1P2 = W/Δt2 = (1/2)m(2v)^2/Δt2 = 2mv^2/Δt2Therefore, the power of the old car is P1 = (1/2)mv^2/Δt1 = 1/2P2

(a) Var[M_9(X)] = 25/9.

(b) P[X1>7] = e^(-7/5).

(c) Using central limit theorem  P[M_9(X)>7] ≈ 1 - Φ((7-5)/(5/3)).

(a) The variance of the sample mean based on nine trials is Var[M_9(X)] = Var[X]/n, where Var[X] is the variance of a single exponential random variable. For an exponential distribution with expected value 5, the variance is equal to the square of the expected value, so Var[X] = 5^2 = 25. Therefore, Var[M_9(X)] = 25/9.

(b) The probability that one outcome exceeds 7, P[X1>7], can be calculated using the exponential distribution's survival function. Since the expected value of an exponential distribution is 5, the survival function is given by S(x) = e^(-x/5). Therefore, P[X1>7] = S(7) = e^(-7/5).

(c) By applying the central limit theorem, we can approximate P[M_9(X)>7] using the normal distribution. The sample mean of nine trials, M_9(X), follows a normal distribution with mean 5 and standard deviation 5/sqrt(9) = 5/3. We can standardize the variable and calculate the probability using the standard normal distribution, which can be approximated as P[M_9(X)>7] ≈ 1 - Φ((7-5)/(5/3)), where Φ represents the cumulative distribution function of the standard normal distribution.
