If the measures of two angles of a triangle are 87 and 17 , what is the measure of the third angle
Answer:
76 degrees
Step-by-step explanation:
The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180
180 - 87 = 93
93 - 17 = 76
The third angle is 76 degrees because then all angles will add up to 180

The best fitting line minimizes the sum of the squared errors when using ______. Multiple choice question. the high-low method scattergraph analysis least-square regression
The best fitting line minimizes the sum of the squared errors when using least-square regression.
When trying to find the best fitting line to a set of data points, the goal is to minimize the differences between the observed data and the predicted values on the line.
The least-square regression method achieves this objective by minimizing the sum of the squared errors, which is the sum of the squared vertical distances between each data point and the corresponding point on the line.
By using the least-square regression approach, we can determine the line that provides the best overall fit to the data by minimizing the total squared differences. This method takes into account all the data points and calculates the line that best represents the relationship between the variables of interest.
The least-square regression line is often referred to as the "best fitting" line because it provides the most accurate prediction of the dependent variable based on the independent variable(s). It is widely used in various fields, including statistics, economics, and social sciences, to analyze and model relationships between variables.

The measure of an angle is 175. 5°. What is the measure of its supplementary angle?
If we have an angle equal to 175.5°, then its supplementary angle is equal to 4.5°.
To solve this problem we must know that an angle and its supplementary add up to 180º, that is, the following equality must be satisfied:
β + α = 180º
The measure of a supplementary angle is the difference between 180° and the given angle. In this case, the given angle is 175.5°. To find the measure of the supplementary angle, we will subtract 175.5° from 180°.
α = 180° - 175.5° = 4.5°
Therefore, the measure of the supplementary angle is 4.5°.

Determine the ideal system sensitivity of a strain gage system expressed in
millivolts per microstrain, given the following: Sg = 2.130, Ei = 1.5 Vdc, G = 3200. Also, determine the ideal slope of the calibration equation in microstrain per millivolt.
The ideal system sensitivity is 0.001003125 mV/με (millivolts per microstrain), and the ideal slope of the calibration equation is 996.875 με/mV (microstrain per millivolt)
How to find ideal system sensitivity ?
Given:
Sg = 2.130
Ei = 1.5 Vdc
G = 3200
We can use the formula:
System Sensitivity = (Excitation Voltage * Strain Gage Sensitivity) / (Gain of the Signal Conditioning System)
to calculate the ideal system sensitivity of the strain gage system expressed in millivolts per microstrain.
Plugging in the values, we get:
System Sensitivity = (1.5 Vdc * 2.130) / 3200 = 0.001003125 mV/με (millivolts per microstrain)
This means that a change of 1 microstrain in the strain gage will produce a change of 0.001003125 mV in the output voltage.
How to find ideal slope of the calibration equation?
To determine the ideal slope of the calibration equation in microstrain per millivolt, we simply take the reciprocal of the system sensitivity. So we get:
Ideal Slope = 1 / System Sensitivity = 1 / 0.001003125 = 996.875 με/mV (microstrain per millivolt)
This means that a change of 1 mV in the output voltage will produce a change of 996.875 microstrain in the strain gage.
Therefore, the ideal system sensitivity of the strain gage system expressed in millivolts per microstrain is 0.001003125 mV/με (millivolts per microstrain), and the ideal slope of the calibration equation in microstrain per millivolt is 996.875 με/mV (microstrain per millivolt).

Ideal slope ≈ 0.0978 micro strain per millivolt
How to determine the ideal system sensitivity of a strain gage system expressed in millivolts per micro strain?We need to use the following formula:
Sensitivity = (Sg × Ei × G) / 1000
where:
Sg = 2.130 (gage factor)
Ei = 1.5 Vdc (input voltage, in volts)
G = 3200 (instrumentation amplifier gain)
Now, let's calculate the sensitivity:
Sensitivity = (2.130 × 1.5 × 3200) / 1000
Sensitivity = 10224 / 1000
Sensitivity = 10.224 millivolts per microstrain
How to determine the ideal slope of the calibration equation in micro strain per millivolt? We need to find the inverse of the sensitivity:
Ideal slope = 1 / Sensitivity
Ideal slope = 1 / 10.224
Ideal slope ≈ 0.0978 micro strain per millivolt

Write the equation of the line that passes through (4, 2) and is parallel to the line y = 2x – 1.
Answer:
Step-by-step explanation:
We will look for a line that has the general form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
A line parallel to y=2x-1 will have the same slope, 2.
We can write y = 2x + b for the new line. We need to find b. We can use the given point in this equation and solve for b:
y = 2x + b
2 = 2(4) + b for (4,2)
2 = 8 + b
x = -6
The parallel line to y=2x-1 that goes through point (4,2) is:
y = 2x-6

We are asked to write the equation of the line that passes through (4, 2) and is parallel to y=2x-1.
\(\triangle~\fbox{\bf{KEY:}}\)
Parallel lines have the same slope.Since the slope of the given line is 2, the slope of the line parallel to this one is also 2.
Now, figure out the y-intercept, c:y=2x+c
We're given a point: (4, 2).Where: 2 is the y-coordinate of the point, and 4 is the x-coordinate.
Now, substitute 2 for y and 4 for x:
\(\longmapsto\sf{2=2(4)+c}\)

\(\longmapsto\sf{2=8+c}\)
Subtract 8 from both sides of the equal sign:

the graph of F(x), shown below, has the same shape as the graph of G(x)=x^2. but it is shifted up 4 units and to the right 2 units. What is its equation
Answer:
Step-by-step explanation:
The graph of \(y=x^2\) in vertex form is \(y=(x-h)^2+k\) where h and k, the vertex, is (0, 0). If we shift the parabola right or left, or up or down, the h and k values take on that reflection. If we move up 4, k goes from a value of 0 to a value of 4; if we move right 2 units, h goes from a value of 0 to a value of 2. Putting that together in work (aka vertex) form:
\(y=(x-2)^2+4\)
A group contains n men and n women. How many ways are there to arrange these people in a row if the men and women alternate? Justify.
So, there are (n!)^2 ways to arrange n men and n women in a row if they alternate genders.
We need to use the principle of multiplication. We first choose the position of the first person in the row, which can be any of the n men or n women. Without loss of generality, let's say we choose a man. Then, for the next position, we need to choose a woman since we are alternating genders. There are n women to choose from. For the third position, we need to choose another man, and there are n-1 men left to choose from (since we already used one). For the fourth position, we need to choose another woman, and there are n-1 women left to choose from. We continue this pattern until all n men and n women are placed in the row.
Using the principle of multiplication, we can find the total number of ways to arrange the people by multiplying the number of choices at each step. Therefore, the total number of ways to arrange the people in a row if the men and women alternate is:
n * n-1 * n * n-1 * ... * 2 * 1
This can be simplified to:
(n!)^2
So, there are (n!)^2 ways to arrange n men and n women in a row if they alternate genders.

(round your answer to the nearest whole number.) 430 incorrect: your answer is incorrect. mi/h
The rate at which the distance from the plane to the station is increasing when it is 5 mi away from the station is 421 mi/h.
Given information:
A plane flying horizontally at an altitude of "1" mi and a speed of "430" mi/h passes directly over a radar station.
z = 1
\(\frac{dx}{dt} = 430\)
We need to find the rate at which the distance from the plane to the station is increasing when it is 5 mi away from the station.
y = 5
According to Pythagoras
\(hypotenuse^2 = base^2 + perpendicular^2\\\\y^2 = x^2 + 1^2\\\\y^2 = x^2 + 1\).... (1)
Put z=1 and y=5, to find the value of x.
\(5^2 = x^2 + 1^2\\\\25 = x^2 + 1\\\\25 - 1 = x^2\\\\24 = x^2\)
Taking square root both sides.
\(\sqrt{24} = x\)
Differentiate equation (1) with respect to t.
\(2y\frac{dy}{dt} = 2x\frac{dx}{dt} + 0\)
Divide both sides by 2.
\(y\frac{dy}{dt} = x\frac{dx}{dt}\)
Put \(x = \sqrt{24}\), y=5, \(\frac{dx}{dt} = 430\) in the above equation.
\(2\frac{dy}{dt} = \sqrt{24}(430)\)
Divide both sides by 2.
\(\frac{dy}{dt} = \frac{\sqrt{24}(430) }{5} \\\\\frac{dy}{dt} = 421.312\\\\\frac{dy}{dt} = 421\)
Hence the answer is the rate at which the distance from the plane to the station is increasing when it is 5 mi away from the station is 421 mi/h.

The distance between the points is equal to 26 units.
How to calculate the distance between the two points?Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Where:
x and y represents the data points (coordinates) on a cartesian coordinate.
Substituting the given parameters into the distance formula, we have the following;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(-9 - (-9))² + (-18 - 8)²]
Distance = √[0² + 26²]
Distance = √[0 + 676]
Distance = √676
