Finally, we can integrate each term of this expression to obtain the solution to the original indefinite integral. The final solution is (1/2)x - (1/2)ln(x² + 1) + C, where C is the constant of integration.

To solve the indefinite integral of the given function, we need to make use of substitution. One of the most appropriate substitutions for this integral is u = x² + 1. By making this substitution, we can simplify the integral to the point where we can apply the power rule of integration. The derivative of u with respect to x is du/dx = 2x. Therefore, we can express dx in terms of du by multiplying both sides of this equation by dx/2. This gives us dx = du/2x. Substituting this into the original integral, we get ∫(x²)/(x²+1) dx = ∫(u-1)/(2u) du. We can simplify this expression to get ∫(1/2) - (1/2u) du.  Overall, this substitution allows us to simplify the integral and arrive at a more manageable form. This demonstrates the power and utility of using substitution when dealing with complex integrals.

The least number of households that should be surveyed to obtain an estimate within a certain confidence interval of the true mean household income cannot be determined without knowing the desired confidence level and the desired margin of error.

To determine the least number of households that should be surveyed, we need to consider the desired confidence level and the desired margin of error. The confidence level represents the level of certainty we want in our estimate, and the margin of error determines the range within which we want the estimate to fall.

The formula to calculate the minimum sample size required for a given confidence level and margin of error is:

n = (Z^2 * σ^2) / (E^2)

Where:

n = minimum sample size

Z = Z-score corresponding to the desired confidence level

σ = standard deviation of the population (unknown in this case)

E = margin of error

Since the standard deviation of the population is unknown, we often use a conservative estimate by assuming a large value or using a pilot study to estimate it. However, without specific values for the confidence level and margin of error, we cannot determine the exact minimum sample size.

In summary, to determine the least number of households that should be surveyed, we need to know the desired confidence level and the desired margin of error. These values will determine the appropriate sample size needed to estimate the mean household income with the desired level of confidence.

Given :

x|  0      1     2      

p| 0.2 0.6  0.2

The expected value of x, E(x) =Σ xp

where x = number of classes and p = probability

E(x) = (0×0.2) + (1×0.6) + (2×0.2)

E(x) = 0 + 0.6 + 0.4

E(x) =  1.0

Step-by-step explanation:

Box B has the smaller range of masses, with a range of 49 grams, compared to Box A's range of 97,649 grams.

The question asks which of the boxes has the smaller range of masses and what is the value of this range in grams (g).
To find the range, we need to subtract the smallest value from the largest value in each box.
In Box A, the smallest value is 4 and the largest value is 97653. So, the range in Box A is 97653 - 4 = 97649 g.
In Box B, the smallest value is 2 and the largest value is 8762. However, we are given that key 35 represents a mass of 53 g and key 51 represents a mass of 51 g. So, the actual largest value in Box B is 51. Therefore, the range in Box B is 51 - 2 = 49 g.
Comparing the ranges, we can see that the range in Box B (49 g) is smaller than the range in Box A (97649 g).

Answer:D

beacuse it is correct  just trust me i have done this class and its correct

The first law of thermodynamics is a fundamental principle in physics that states energy cannot be created or destroyed, only converted from one form to another. It can be expressed in terms of heat and work through the equation:

ΔU = q - w

where ΔU represents the change in internal energy of a system, q represents the heat added to the system, and w represents the work done on or by the system.

Now, let's address when the quantities q and w would be negative numbers.

1) When q is negative: This occurs when heat is removed from the system, indicating an energy loss. For example, when a substance is cooled, heat is extracted from it, resulting in a negative value for q.

2) When w is negative: This occurs when work is done on the system, decreasing its energy. For instance, when compressing a gas, work is done on it, leading to a negative value for w.

In both cases, the negative sign indicates a reduction in energy or the transfer of energy from the system to its surroundings.

In summary, the first law of thermodynamics can be expressed as ΔU = q - w, and q and w can be negative numbers when energy is lost from the system through the removal of heat or when work is done on the system.

Answer: 20% Chance

Step-by-step explanation:

Probability of flipping heads on a coin is 50% and this wheel landing on a even number is 40% you multiply .50 and .40 and you get .20.

Probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).

" Probability is a mathematical expression which represents ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability= (Number of favourable outcomes) / (Total number of outcomes)

For Independent Event

P(A∩B) = P(A)×P(B)

According to the question,

'A' represents the probability of spinning an even number

'B' represents the probability of flipping heads

Possible outcomes on spinner = { 1, 2, 3, 4, 5}

Favourable outcomes of spinning an even number = 2

Total number of outcomes = 5

Substitute the value in the formula we get,

P(A) = ( 2 / 5)

Possible outcomes of flipping a coin = { head , tail}

Total outcomes of flipping a coin =2

Favourable outcomes flipping heads = 1

P(B) = (1 / 2)

Probability of spinning an even number and flipping heads P(A∩B)

A and B are independent events

Substitute the value of P(A) and P(B) in the formula we get,

P(A∩B) = ( 2/ 5)×(1/2)

            = 2 /10

Hence, probability of spinning an even number and flipping heads P(A∩B) = (2 / 10).

Step-by-step explanation:

The error involved in approximating the sum of the given series by the sum of the first five terms of the series is `R5 = 1/6³ + 1/7³ + ...`.

To estimate the error that is made by approximating the sum of the given series by the series the first 5 terms 1/k³, we can use the remainder term of a convergent series.

The given series is ∑ 1/k³ from k = 1 to infinity.We have to find the error involved in approximating the sum of the given series by the sum of the first five terms of the series.

That is, we need to find the difference between the actual sum of the series and the sum of the first five terms of the series.

The sum of the series is given by: `S = 1/1³ + 1/2³ + 1/3³ + 1/4³ + ... + 1/n³ + ...` We can use the remainder term of the series to find the error in approximation.

The remainder term `Rn` is given by: `Rn = Sn - S` where `Sn` is the sum of the first `n` terms of the series. Thus, we have to find the remainder term for `n = 5`.

The remainder term `Rn` is given by: `Rn = S - Sn = 1/6³ + 1/7³ + ...` Since the given series is convergent, the remainder term `Rn` tends to zero as `n` tends to infinity.

So, if we take the sum of the first five terms of the series, the error involved in approximation is given by the remainder term `R5`.

The error involved in this approximation is very small and can be neglected.

Answer:

how much hours and where is it going.

Step-by-step explanation:

The most appropriate type of graph for graphing heart rate data over the time period of 120 seconds would be a line graph or a scatter plot.

A line graph is useful when we want to show the trend or changes in a variable over time. It would allow us to plot the heart rate on the y-axis and the time on the x-axis, connecting the data points with a line to represent the change in heart rate over the 120-second period.

A scatter plot can also be used to display heart rate data over time. In a scatter plot, each data point represents a heart rate measurement at a specific time point. By plotting the heart rate on the y-axis and the time on the x-axis, we can observe the distribution of the data points and any potential patterns or trends.

Ultimately, the choice between a line graph and a scatter plot depends on the specific nature of the data and the purpose of the graph. If the heart rate data is continuous and measured at regular intervals, a line graph would be a suitable choice. If the heart rate data is more discrete or irregularly measured, a scatter plot would be more appropriate.
