Hey I need some help on this question

The integral ∫[0 to 1] x² dx evaluates to 1/3.

To evaluate this integral, we can use the power rule for integration. Applying the power rule, we increase the power of x by 1 and divide by the new power. Thus, integrating x² gives us (1/3)x³.

To evaluate the definite integral from x = 0 to x = 1, we substitute the upper limit (1) into the antiderivative and subtract the result when the lower limit (0) is substituted.

Using the Fundamental Theorem of Calculus, the area under the curve is given by the expression A = ∫[0 to 1] f(x) dx. For this case, f(x) = x².

To approximate the area using right endpoints, we can use a Riemann sum. Dividing the interval [0, 1] into subintervals and taking the right endpoint of each subinterval, the Riemann sum can be expressed as lim[n→∞] Σ[i=1 to n] f(xᵢ*)Δx, where f(xᵢ*) is the value of the function at the right endpoint of the i-th subinterval and Δx is the width of each subinterval.

In this specific case, since the function f(x) = x² is an increasing function on the interval [0, 1], the right endpoints of the subintervals will be f(x) values.

Therefore, the area under the curve from x = 0 to x = 1 can be expressed as lim[n→∞] Σ[i=1 to n] (xi*)²Δx, where Δx is the width of each subinterval and xi* represents the right endpoint of each subinterval.

From the question, we have the following parameters that can be used in our computation:

The circle

The measure of angle at the center of the circle is calculated as

Center = 2 * 31

So, we have

Center = 62

The sum of angles in a triangle is 180

So, we have

x + x + 62 = 180

This gives

2x = 118

Divide by 2

x = 59

Answer:

The length of side of patio is 11.27 feet.

Option A is correct option.

Step-by-step explanation:

Area of patio = 127 ft^2

We need to find side length of the patio.

Since the patio is square, the formula used is:

\(Area\: of\: square = l^2\)

where l is the side length of square.

Now, putting value of area we can find area of square.

\(Area\: of\: square = l^2\\127=l^2\\Switching\:sides\:\\l^2=127\\Taking\:square\:root\:on\:both\:sides\\\sqrt{l^2}=\sqrt{127} \\l=11.27\)

So, the length of side of patio is 11.27 feet.

Option A is correct option.

False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.

In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.

When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.

In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.

However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.

Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.

The area of the small sector is about 178.72 cm^2.

Ratio of rise to run between the points (-2, 8) and (4, -3) = -11/6

To find the ratio of rise to run between two points, we need to calculate the difference in the y-coordinates (rise) and the difference in the x-coordinates (run) between the two points.

Given points:

Point 1: (-2, 8)

Point 2: (4, -3)

Rise = difference in y-coordinates = y2 - y1 = -3 - 8 = -11

Run = difference in x-coordinates = x2 - x1 = 4 - (-2) = 6

Therefore, the ratio of rise to run can be calculated as:

Ratio of rise to run = Rise / Run = -11 / 6

Thus, the ratio of rise to run between the points (-2, 8) and (4, -3) is -11/6.

Answer:

The answer is

\( \sqrt[3]{ {x}^{2} } \)

Step-by-step explanation:

\( \frac{ {x}^{ \frac{5}{6} } }{ {x}^{ \frac{1}{6} } } \)

Since they have the same base and are dividing we can use the rules of indices

That's

subtract the exponents

So we have

\( {x}^{ \frac{5}{6} - \frac{1}{6} } \)

\( {x}^{ \frac{4}{6} } \)

\( = {x}^{ \frac{2}{3} } \)

Rewriting it in radical form

Answer:

The slope is -6

Step-by-step explanation:

12x+2y=24

We want to find the slope of a line that is parallel to this line.

Parallel lines have the same slope, so we need to find the slope of this line.

We can get this equation in slope intercept form to find the slope

y = mx+b  where m is the slope

Subtract 12x from each side

2y = -12x+24

Divide each side by 2

y = -12x/2 +24/2

y = -6x+12

The slope is -6

If you increase the confidence level, the confidence interval increases. therefore the correct answer is option D. increases

When you increase the confidence level, the confidence interval increases as well. The confidence level represents the degree of certainty or level of confidence that the true population parameter lies within the calculated interval.

A confidence interval is constructed based on sample data and is influenced by two main factors: the level of confidence desired and the variability within the data.

By increasing the confidence level, you are requesting a higher level of certainty that the population parameter falls within the interval.To achieve a higher level of confidence, the interval needs to widen to encompass a larger range of possible values. This increase in the width of the interval reflects the increased level of certainty desired, allowing for a larger margin of error and a wider range of plausible values for the population parameter.

Therefore, when you increase the confidence level, the confidence interval increases in width.

(a) We have to determine the sample size for the above sample.

The number of participants or observations included in a study is referred to as the sample size. This number is commonly represented by the symbol n.

Sample Size (n) = 15

(b) We have to calculate the sample mean for these data.

Sample Mean = Total Sum of data/Total Number

Sample Mean = (3.4 + 2.5 + 4.8 + 2.9 + 3.6 + 2.8 + 3.3 + 5.6 + 3.7 + 2.8 + 4.4 + 4.0 + 5.2 + 3.0 + 4.8)/15

Sample Mean = 56.8/15

Sample Mean = 3.8

(c) We have to calculate the sample median.

To define the sample median we first represent the data in ascending order.

2.5, 2.8, 2.8, 2.9, 3.0, 3.3, 3.4, 3.6, 3.7, 4.0, 4.4, 4.8, 4.8, 5.2, 5.6

Sample Size(n) = 15

So Median = (n+1)/2th term

Median = (15 + 1)/2th term

Median = 16/2th term

Median = 8th term

So the 8th term in the given data is 3.6. So,

Median = 3.6

(d) We have to compute the 20% trimmed mean for the above data set.

To compute the 20% termed mean, remove 20% of the largest and 20% of the smallest elements from the sample and compute the mean of the new sample.

New sample: 2.9 3.0 3.3 3.4 3.6 3.7 4.0 4.4 4.8

New Mean = 33.3/9

New Mean = 3.7

(e) We have to check is the sample mean for these data more or less descriptive as a center of location than the trimmed mean.

The mean value is 3.8, the median value is 3.6, and the trimmed mean value is 3.7. As a result, the sample mean is less descriptive as the location's center (median) than the trimmed mean.
