If M is the midpoint of AB, A(-3, 4) and M(-1, 2) find the coordinates
of B.

Answer:

42 minutes are not spent on instructions

Step-by-step explanation:

First, we must find out how many minutes is in \(\frac{7}{8}\) hour

\(60*\frac{7}{8}=\frac{60*7}{8} =\frac{420}{8} =52.5\)

In \(\frac{7}{8}\) hour, there is about 52 \(\frac{1}{2}\) minutes

Then we must add up the fractions that are NOT the instructions

\(\frac{1}{2} +\frac{3}{10} =\frac{5}{10} +\frac{3}{10} =\frac{8}{10} =\frac{4}{5}\)

\(\frac{4}{5}\) of the total time (52 \(\frac{1}{2}\) minutes) is not spent on instructions

Then we must multiply the fraction of time spent on other things (\(\frac{4}{5}\)) by total time (52 \(\frac{1}{2}\) minutes) in order to find out how many minutes weren't spent on instructions.

\(\frac{4}{5}*52 \frac{1}{2} =\frac{4}{5}* \frac{105}{2}=\frac{420}{10} =42\)

42 minutes are not spent on instructions

There are 720 permutations of {a, b, c, d, e, f, g} end with a. So the option 4 is correct.

If we choose components without repetition, P(7, 6) would imply that we are attempting to find a 7-permutation on the set {b, c, d, e, f, g}. This is not possible.

The same amount of these permutations finish in "a," "b," "c," and so forth.

The amount of permutations that finish in "a" is therefore just: 5040/7 = 720, the same as 6! = P (6,6)

P(7,6) is incorrect because it is asking for the number of 6-permutations on a set of 7 elements.

Since the last character must be a, there are only 6 elements that can be arranged in any order to form a permutation.

Therefore, the correct answer is P(6,6) = 6! = 720.

So the option 4 is correct.

The absolute uncertainty of the product is the sum of the absolute uncertainties of the individual terms. The answer to (c) is 3.11 ± 0.26 mmol, with a percent relative uncertainty of 8.3%.

The absolute uncertainty of the first term is 1.0 mM, the absolute uncertainty of the second term is 0.2 mL, and the absolute uncertainty of the third term is 0.2 mL. So, the absolute uncertainty of the product is 1.0 + 0.2 + 0.2 = 1.4 mM.

The percent relative uncertainty of the product is the absolute uncertainty divided by the value of the product, multiplied by 100%. So, the percent relative uncertainty of the product is 1.4 / 91.3 * 100% = 1.5%.

The value of the product is 91.3 * 40.3 / 21.1 = 174.379 mM.

Therefore, the answer to (b) is 174.379 ± 1.4 mM, with a percent relative uncertainty of 1.5%.

The absolute uncertainty of the difference is the sum of the absolute uncertainties of the individual terms. The absolute uncertainty of the first term is 0.05 mmol, the absolute uncertainty of the second term is 0.01 mmol, and the absolute uncertainty of the third term is 0.2 mL. So, the absolute uncertainty of the difference is 0.05 + 0.01 + 0.2 = 0.26 mmol.

The percent relative uncertainty of the difference is the absolute uncertainty divided by the value of the difference, multiplied by 100%. So, the percent relative uncertainty of the difference is 0.26 / 3.12 * 100% = 8.3%.

The value of the difference is 4.97 - 1.86 = 3.11 mmol.

Therefore, the answer to (c) is 3.11 ± 0.26 mmol, with a percent relative uncertainty of 8.3%.

The appropriate statistic to use here would be the dependent groups t-test, also known as a paired t-test.

A dependent groups t-test is used when the same subjects are measured under two different conditions, as is the case here with the children taking the IQ test both with and without a prior dose of glucose. The paired t-test compares the means of the two related conditions to determine if there is a statistically significant difference.

By using equivalent forms of the IQ test for both conditions and comparing the scores within each child, the dependent groups t-test can assess whether the strong doses of glucose have a significant effect on IQ test performance.

Therefore, the experimenter should employ the dependent groups t-test to analyze the data and assess the impact of glucose on intelligence test performance.

Answer: The lowest possible product would be -6724 given the numbers 82 and -82.

We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.

Next we'll multiply the numbers together.

x(x+164)

x^2 + 164x

Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2

-b/2a = -164/2(1) = -164/2 = -82

So we know one of the values is -82. We can plug that into the equation to find the second.

x + 164

-82 + 164

These are the parametric equations of the line that passes through the points (6, 2) and (3, 4).

To find the parametrization of the line that passes through the points (6,2) and (3,4), we can use the following steps:Step 1: Find the direction vector of the line.The direction vector can be found by subtracting the coordinates of one point from the coordinates of the other point.(3, 4) - (6, 2) = (-3, 2)The direction vector of the line is (-3, 2).Step 2: Choose a parameter t and find the parametric equations of the line.To find the parametric equations of the line, we need to choose a parameter t. The parameter t will give us the coordinates of all the points on the line. We can choose any value of t.To make the calculations easier, we can choose t = 0 for one of the points. Let's choose t = 0 for the point (6, 2). This means that when t = 0, the coordinates of the point on the line are (6, 2).We can now use the direction vector and the point (6, 2) to find the parametric equations of the line:x = 6 - 3t y = 2 + 2t

Before performing a significance test about a population mean or proportion, the following conditions must be verified:

Sample Size: The sample size should be sufficiently large to allow the application of the normal distribution. A minimum sample size of 30 is required to meet this requirement.

Normality: The sample should be approximately normally distributed. When the sample size is greater than or equal to 30, the central limit theorem ensures normality. For sample sizes of less than 30, the data should be examined for normality. If the distribution is skewed or has outliers, nonparametric tests should be considered.

Independence: The observations in the sample should be independent of one another. This means that the response from one observation does not depend on the response from another observation.

Equal Variance: The variance of the population should be approximately equal to the variance of the sample. If the variances are unequal, a modified t-test should be used instead of the traditional t-test.

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

The rectangular aquarium requires 374,400 cubic centimeters of water to completely fill it.

To calculate the volume of the rectangular aquarium, we multiply its length, width, and height. In this case, the length is given as 4.5 meters, the width is 3.2 meters, and the height is 2.6 meters.

Converting the measurements to centimeters (1 meter = 100 centimeters), the length becomes 450 centimeters, the width becomes 320 centimeters, and the height becomes 260 centimeters.

Now, multiplying these three dimensions together, we get 450 * 320 * 260 = 37,440,000 cubic centimeters. Therefore, 374,400 cubic centimeters of water are needed to completely fill the rectangular aquarium.

The immigration agent is 100% busy on average.

Based on the information provided, we can calculate the arrival rate of entrants as follows:

Arrival rate = 1/6 minutes per entrant = 0.1667 entrants per minute

Next, we can calculate the processing rate of the immigration agent as follows:

Processing rate = 120 entrants per 8 hour shift = 0.05 entrants per minute

Using Little's Law, we can calculate the average number of entrants in the system as follows:

Average number of entrants = Arrival rate x Average time in the system

where Average time in the system = 1/Processing rate

Plugging in the values, we get:

Average number of entrants = 0.1667 x (1/0.05) = 3.333

Therefore, the immigration agent is busy with an average of 3.333 entrants in the system. To determine how busy she is as a percentage, we can use the following formula:

% utilization = (Average number of entrants / Number of servers) x 100%

In this case, there is only one immigration agent, so the number of servers is 1. Plugging in the values, we get:

% utilization = (3.333 / 1) x 100% = 333.3%

Since the maximum utilization cannot exceed 100%, the answer is 100%. Therefore, the immigration agent is 100% busy on average.

The expression for the inverse function f^-1(x) is:

\(`f^-1(x) = (x + 4)^(1/3)`\)

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.

Given function is

\(f(x) = x³ - 4.\)

To find the inverse function, let y = f(x) and swap x and y.

Then, the equation becomes:

\(x = y³ - 4\)

Next, we will solve for y in terms of x:

\(x + 4 = y³ y = (x + 4)^(1/3)\)

d. Expected life in years of the depreciable asset. The acceptable way to express the useful life of a depreciable asset is in terms of the expected life in years.

The useful life refers to the period of time over which the asset is expected to contribute to the revenue-generating activities of a business.

While options a, b, and c may be relevant factors for certain specific assets (such as units produced, hours of productivity, or miles driven), they do not encompass the overall concept of useful life. Useful life is a broader measure that takes into account the anticipated duration of productive use, regardless of specific output or activity metrics.

Expressing the useful life in years provides a common standard for comparison and allows for consistency in depreciation calculations and financial reporting. It is a practical and widely accepted approach to estimating the lifespan of a depreciable asset.

It is worth noting that the estimated useful life in years may vary depending on the nature of the asset and industry practices. It is typically determined based on factors such as technological advancements, physical wear and tear, economic obsolescence, and the intended purpose of the asset.
