The value of E(x2) is p.

Bernoulli's Random Variable:A Bernoulli Random Variable is a random variable that takes on a value of 1 with probability p, and 0 with probability 1 – p.Let x = 1 if a randomly selected vehicle passes an emissions test and x = 0 otherwise.

Then, x is a Bernoulli RV with pmf p(1) = p and p(0) = 1 – p.

Compute E(x2):Given, pmf p(1) = p and p(0) = 1 – p.Now, E(x2) = E(x * x) = P(x = 1) * 1^2 + P(x = 0) * 0^2 = p * 1 + (1 - p) * 0 = p..

E(x2) = p.

The computed answer for E(x^2) is p, which means it takes a value of 1 with probability p.

To convert kilometers per liter to miles per gallon, we need to use conversion factors. There are approximately 3.785 liters in a gallon, and there are approximately 1.609 kilometers in a mile.

So, first we convert the fuel efficiency of the hybrid vehicle from kilometers per liter to kilometers per gallon:

1 km/liter * 3.785 liters/gallon = 3.785 km/gallon

Then, we convert kilometers per gallon to miles per gallon:

3.785 km/gallon * 1 mile/1.609 km = 2.35 miles/gallon

Therefore, the gas mileage of the hybrid vehicle is approximately 2.35 miles per gallon.

It's worth noting that the mileage rating of a hybrid vehicle can vary depending on factors such as driving conditions and habits, so the actual gas mileage may differ from the stated rating. Additionally, the conversion factors used here are approximate, so the exact gas mileage may vary slightly depending on the specific conversion factors used.

By using the simulated results and the law of large numbers, we can estimate that the probability of answering exactly 15 questions correct on a 30-question exam with a 35% chance of getting each question correct is approximately 7.2%.

Based on the simulated results, we can estimate the probability of answering exactly 15 questions correct on a 30-question exam with a 35% chance of getting each question correct. To do this, we first need to look at the histogram or table of the simulated results to see how many of the 1000 exams scored 15.

If we look at the histogram or table, we can see that there were 72 out of 1000 exams that scored exactly 15. This means that the proportion of exams that scored 15 is 72/1000 or 0.072.

Using the law of large numbers, we can estimate that this proportion is the same as the probability of answering exactly 15 questions correctly on a 30-question exam with a 35% chance of getting each question correct. Therefore, the estimated probability of answering exactly 15 questions correct is 0.072 or 7.2%.

    a) Gas has a volume of 12 liters.

    b) 12 liters of oxygen gas will be consumed during the reaction.

Step-by-step explanation:

Moles of Substances:

We measure the quantity of atoms and molecules in moles, which is equal to 6.022 ×10²³, Avogadro's number, because they are too small to be counted or weighed individually. A substance's atomic mass is multiplied by Avogadro's number to get its mass in grams.

Here, Half a mole of carbon is equal to six grams of carbon. since 12 grams make up one mole of carbon. Since carbon dioxide has the chemical formula CO2, when a mole of carbon is fully combusted, it will result in the production of a mole of carbon dioxide gas.

a) Half a mole of gas has a volume of 12 liters because one mole of gas at RTP consumes 24 liters.

b) Due to the fact that each oxygen molecule contains two oxygen atoms and each carbon dioxide molecule contains two oxygen atoms, 12 liters of oxygen gas will be consumed during the reaction.

Answer: <BOC and <COD are supplementary. The sum of their angle measures is 180 degrees.

Step-by-step explanation:

Since angles BOC and COD both form a horizontal line (line BOD) when added together, the two angles are supplementary. Supplementary angles always equal 180 degrees when added together because they form a straight line, or half of a circle.

Therefore, <BOC and <COD are supplementary, and the sum of their angle measures is 180 degrees.

Anurag walks 2 km every day on his way back.

i. To find the distance Anurag walks every day on his way back, we need to calculate the distance covered by walking.

Given that Anurag takes an auto to travel 1/6 of the total distance and covers 4/5 of the remaining distance by bus, the remaining distance he has to walk can be found by subtracting the distance covered by the auto and bus from the total distance.

Total distance = 12 km

Distance covered by auto = 1/6 * 12 km = 2 km

Remaining distance = Total distance - Distance covered by auto = 12 km - 2 km = 10 km

Distance covered by bus = 4/5 * 10 km = 8 km

Distance walked = Remaining distance - Distance covered by bus = 10 km - 8 km = 2 km

Therefore, Anurag walks 2 km every day on his way back.

ii. If Anurag goes to the office 5 days in a week, the total distance he walks every week can be calculated by multiplying the distance walked every day by the number of days he goes to the office.

Distance walked every week = Distance walked every day * Number of days

Distance walked every week = 2 km/day * 5 days/week = 10 km/week

Therefore, Anurag walks 10 km every week.

iii. Anurag walks some distance daily because the office is not directly accessible by auto or bus. Walking the remaining distance is necessary to reach his destination. Walking provides physical exercise and can also be a convenient and cost-effective mode of transportation for shorter distances. It allows Anurag to maintain an active lifestyle and may have additional benefits such as reducing carbon emissions and contributing to his overall health and well-being.

Therefore, the control represented by the decimal value 15 is the one with all four bits set to 1.

In digital electronics, binary digits (bits) are used to represent numbers and control various devices. Each bit can have a value of either 0 or 1, and by combining multiple bits, we can represent larger numbers or control signals. The decimal system, which we are most familiar with, uses 10 digits (0-9) to represent numbers. In contrast, the binary system uses only 2 digits (0 and 1) to represent numbers or controls. To convert a decimal number to binary, we repeatedly divide the number by 2 and keep track of the remainders. The binary representation of a number is the sequence of remainders read in reverse order.

The decimal value 15 can be represented as a control with four binary digits (bits), as follows:

1 1 1 1

Each bit represents a power of 2, from right to left: 2^0, 2^1, 2^2, 2^3. Adding up the powers of 2 where there is a 1 in the binary representation gives us the decimal value.

So, in this case, we have:

1x2^0 + 1x2^1 + 1x2^2 + 1x2^3 = 1 + 2 + 4 + 8 = 15

Step-by-step explanation:

a negative exponent means 1/...

the number in the numerator means "to the power of".

the number in the denominator means take the root of that power.

so, we have to take the third root of the expression, or this then to the power of 4, and finally build 1/... if the whole result.

and the sequence is not making a difference.

the third root of of 27/8 = 3/2

this to the power of 4 = 81/16

The presence of the term 2ny(n−1) violates the homogeneity property because it contains a nonlinear term with a coefficient dependent on 'n'. Therefore, the system does not satisfy both superposition and homogeneity, making it nonlinear.

To determine whether the system described by the equation

y(n−2) + 2ny(n−1) + 10y(n) = u(n)

is linear or not, we need to check two properties: superposition and homogeneity.

1. Superposition: A system is linear if it satisfies the superposition property, which states that the response to the sum of two inputs is equal to the sum of the individual responses to each input.

Let's consider two inputs u1(n) and u2(n) with corresponding outputs y1(n) and y2(n) for the given system:

For input u1(n):

y1(n−2) + 2ny1(n−1) + 10y1(n) = u1(n)

For input u2(n):

y2(n−2) + 2ny2(n−1) + 10y2(n) = u2(n)

Now, let's consider the sum of the inputs u1(n) + u2(n):

u(n) = u1(n) + u2(n)

The corresponding output for the combined input should be y(n):

y(n−2) + 2ny(n−1) + 10y(n) = u(n)

To determine linearity, we need to check whether y(n) is equal to y1(n) + y2(n). If the equation holds, the system is linear.

2. Homogeneity: A system is linear if it satisfies the homogeneity property, which states that scaling the input signal scales the output signal by the same factor.

Let's consider an input signal u(n) with output y(n) for the given system:

y(n−2) + 2ny(n−1) + 10y(n) = u(n)

Now, if we scale the input signal by a constant α, the new input becomes αu(n). We denote the corresponding output as y_alpha(n):

y_alpha(n−2) + 2ny_alpha(n−1) + 10y_alpha(n) = αu(n)

To determine linearity, we need to check whether y_alpha(n) is equal to αy(n). If the equation holds for any α, the system is linear.

Now, let's analyze the given system:

y(n−2) + 2ny(n−1) + 10y(n) = u(n)

The presence of the term 2ny(n−1) violates the homogeneity property because it contains a nonlinear term with a coefficient dependent on 'n'. Therefore, the system does not satisfy both superposition and homogeneity, making it nonlinear.
