Triangulation is the method of finding the location of an object based on the measurements made from the two other locations. The above statement is true statement.

Triangulation is the division of a face or plane polygon into a series of triangles, usually with the limitation that each side of a triangle is fully shared by two adjacent triangles. In geometry, triangulation is the division of planar objects into triangles, or more broadly, the division of high-dimensional geometric objects into simplifications. Triangulation of a 3D volume involves subdivision into packed tetrahedra that directly measure distances to points. It is a method for finding the location of the object.

This month's forecast using exponential smoothing with alpha = 0.2, if August's forecast was 145 is  148..

The exponential window function is a general method for smoothing time series data known as exponential smoothing. In contrast to the ordinary moving average, which weights previous data equally, exponential functions use weights that decrease exponentially with time.

The exponential smoothing with an alpha of .2 can be expressed as

F(t) = α*D(t) + (1-α)*F(t-1)

α = 0.2

F(t) = forecast for this month (October)

D(t) = actual demand for the last month (September) = 160

F(t-1) = forecast for last month (August) = 145

Then this can be expressed as ;

0.2*160 + (1-0.2)*145

= 32 + 116

The sample in this example is D) the small group of college students who are observed. The correct option is D.

The researcher has identified college students as her group of interest, but it is not feasible or practical to observe or study all college students. Therefore, she needs to select a subset of college students, which is known as a sample. In this case, she has chosen to observe a small group of local college students, which is the sample. It is important to note that the sample needs to be representative of the larger population of interest, in this case, all college students, in order for the results to be applicable to the larger group.

While the sample in this example is only a small group of local college students, the researcher would need to ensure that they are representative of all college students in order for the results to be generalizable.

Statistical process control (SPC) is a technique used in quality control to monitor and control a process over time

What is used to periodically check that a process is in statistical control?

a. sampling

b. scrap parts

c. the process is only measured in the beginning 100 percent inspection.

a. Sampling is used to periodically check that a process is in statistical control.

Statistical process control (SPC) is a technique used in quality control to monitor and control a process over time. SPC involves collecting and analyzing data on the process, and using statistical methods to determine whether the process is in statistical control (i.e., producing consistent and predictable results) or is out of control (i.e., producing inconsistent or unpredictable results).

One way to monitor a process using SPC is to use sampling. This involves taking a sample of parts or products from the process at regular intervals, and measuring certain characteristics of the sample (such as dimensions, weight, or color). The data collected from the samples can then be analyzed using statistical methods to determine whether the process is in control or out of control.

If the data collected from the samples indicates that the process is out of control (i.e., producing inconsistent or unpredictable results), corrective action can be taken to bring the process back into control. By regularly monitoring and adjusting the process using SPC techniques like sampling, organizations can ensure that their processes are producing consistent and high-quality results.

Step-by-step explanation:

The value of the definite integral ∫ [sinx+cosx]dx over the interval 0 to 2π, where [] represents the greatest integer function, is equal to 2.

The greatest integer function [x] returns the largest integer less than or equal to x. To evaluate the given integral, we need to split the interval [0, 2π] into subintervals where the values of sinx and cosx change.

For each subinterval, we evaluate the integral of [sinx+cosx] over that interval. Since the greatest integer function only takes integer values, [sinx+cosx] will take different constant values for different subintervals.

In the interval [0, π/2), both sinx and cosx are positive, so [sinx+cosx] = 1. Therefore, the integral over this interval is equal to π/2 – 0 = π/2.

In the interval [π/2, π), sinx is positive and cosx is negative, so [sinx+cosx] = 0. The integral over this interval is 0 – (π/2) = -π/2.

In the interval [π, 3π/2), both sinx and cosx are negative, so [sinx+cosx] = -1. The integral over this interval is equal to 0 – (-π/2) = π/2.

In the interval [3π/2, 2π], sinx is negative and cosx is positive, so [sinx+cosx] = 0. The integral over this interval is (π/2) – 0 = π/2.

Adding up the integrals over each subinterval, we get (π/2) + (-π/2) + (π/2) + (π/2) = 2π/2 = 2.

Therefore, the value of the definite integral ∫ [sinx+cosx]dx over the interval 0 to 2π is equal to 2.

The range in a set of data is the difference between the maximum and minimum values in the set.

To find the range of snowfall amounts, we need to look at the line plot and identify the highest and lowest amounts of snowfall that were recorded.

Let's say that the highest amount recorded was 30 inches and the lowest amount recorded was 5 inches. Then the range would be:

range = highest amount - lowest amount

range = 30 - 5

An appropriate statement of the null hypothesis, H₀ is that: A. The proportion of contaminated wrist-watches from medical personnel is the same as the proportion of contaminated wrist-watches from security guards, i.e., H0: p = 46.6%.

In Mathematics, a null hypothesis (H₀) can be defined the opposite of an alternate hypothesis (Ha) and it asserts that two (2) possibilities are the same.

For an experiment to test the contamination of medical personnel wrist-watches at a New York hospital, the appropriate null hypothesis and alternative hypothesis would be given by this mathematical expression:

H₀: p = 10.

To find the coefficient of x² in the expansion of (1-4x+x²/2)⁴, we can use the expansion of (2-p)⁴ and substitute p with (1-4x+x²/2).

The expansion of (2-p)⁴ is given by 1 - 8p + 24p² - 32p³ + 16p⁴. We can substitute p with (1-4x+x²/2) to get the expansion of (1-4x+x²/2)⁴. By replacing p with (1-4x+x²/2) in each term of the expansion, we obtain the following expression:

1 - 8(1-4x+x²/2) + 24(1-4x+x²/2)² - 32(1-4x+x²/2)³ + 16(1-4x+x²/2)⁴.

To find the coefficient of x², we need to identify the term that contains x². In this case, the term containing x² is 24(1-4x+x²/2)². Expanding this term further, we get: 24(1-8x+8x²/2-16x²+16x³/2+x⁴/4).

Simplifying this expression, we obtain: 24 - 192x + 96x² - 96x³ + 12x⁴.

Therefore, the coefficient of x² in the expansion of (1-4x+x²/2)⁴ is 96.

The evaluation of the logarithmic expression log6 21 is approximately 1.70.

To evaluate the logarithmic expression log6 21, we need to determine the exponent to which 6 must be raised to obtain 21. In other words, we need to find the value of x in the equation 6ˣ = 21. To solve for x, we can use the logarithmic property that states log base b of a equals x if and only if be  = a. In this case, we have log6 21 = x, so 6ˣ  = 21.

To find the value of x, we can rewrite the equation using exponential notation: 6ˣ  = 21. Taking the logarithm of both sides with base 6, we get: log6 (6ˣ ) = log6 21 Using the logarithmic property, we can simplify the equation to: x = log6 21. Therefore, the value of x is equal to the logarithm of 21 with base 6. To evaluate this expression, we can use a calculator or logarithmic tables. The approximate value of log6 21 is 1.70.

Hence, the evaluation of the logarithmic expression log6 21 is approximately 1.70.

When 2 men pushes car with mass 1800 kg and their combined horizontal forces are 1000 N, then frictional force acting on the car is 550 N.

The situation can be depicted in the attached picture. F1 and F2 are the horizontal forces of both men, while Fr is the frictional force. Remember that a frictional force is always the opposite of the direction of velocity.

Apply the 2nd Newton law of motion:

∑F = m.a

Where:

∑F = resultant of forces

m = mass of object

a = acceleration

In this situation, ∑F = F1 + F2 - Fr

The given parameters:

m = 1800 kg

a =  0.25 m/s²

F1 + F2 = 1000 N

Substitute these parameters into the  2nd Newton law:

F1 + F2 - Fr = m.a

1000 - Fr = 1800 . (0.25)

1000 - Fr  = 450

Fr = 1000 - 450 = 550 N
