For given circle value of arc KT will be 147m.

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

and Area of circle = πr²

The reason is that the absolute value of a number discards the sign, so it can't be negative as the absolute value of a number is the distance of the number from zero.

Mean Absolute Error (MAE) is a measure of the difference between the predicted value and the actual value. It is calculated by taking the absolute value of the difference between each predicted value and the actual value, and then averaging the differences.

MAE is always positive because it is calculated using the absolute value of the errors, which always results in a positive value. The absolute value function removes the negative sign from any negative errors, so all errors are treated as positive. Therefore, the sum of all errors will always be positive regardless of whether the predicted values are greater or less than the actual values.

It's used in regression problems to measure how good the model is by comparing the actual value and the predicted value. Since MAE is a positive value, it gives a clear understanding of how far the predicted value is from the actual value, which helps to understand the model's performance.

Pilot should take reverse bearing, calculated using atan2(East,North),converted in degrees.

What is radian ?

A radian is a unit of measurement for angles. It is defined as the ratio of the length of an arc of a circle to the radius of that circle. One radian is approximately 57.3 degrees. Radians are often used in mathematics, physics, and engineering because they allow for a more natural way of measuring angles and help simplify certain calculations.

To find the bearing, we can use the formula ,

Bearing = atan2(East, North)

Where East is the number of miles east of the airport and North is the number of miles north of the airport.

The atan2 function is a variation of the arctangent function, which returns the angle (in radians) whose tangent is the quotient of its two arguments. This function is defined for all real arguments and returns a value between -π and π.

So you can convert the bearing from radians to degrees using the formula ,

degrees = bearing * (180/π)

Step-by-step explanation:

The radius of the circle is [tex]\sqrt{(-1-(-4))^2 +(\sqrt{108}-0)^2}=\sqrt{117}[/tex].

Using the center-radius form for the equation of a circle, the equation is [tex](x+1)^2+y^2=117[/tex].

Answer:

[tex](x+1)^2+y^2=117[/tex]

Step-by-step explanation:

Equation of the circle: (x - h)² + (y - k)² = r²

(x, y) – any point in the circle

(h, k) – the center of the circle

r – the radius of the circle

(-4, √108) – (x , y)

(-1, 0) – (h, k)

r – ?

[tex](x-h)^2+(y-k)^2=r^2\\\\((-4)-(-1))^2+((\sqrt{108})-(0))^2=r^2\\\\(-4+1)^2+(\sqrt{108}-0 )^2=r^2\\\\(-3)^2+(\sqrt{108} )^2=r^2\\\\9+108=r^2\\\\r^2=117\\\\r^2=9*13\\\\\sqrt{r^2}=\sqrt{9*13} \\\\r=3\sqrt{13}[/tex]

Now that we know what's the r value:

There are many types of functions and each type of function has its own characteristics. This implies that their graph has also its own characteristics.

Based on the graph, the absolute value function has a "V-Shaped" graph.

Every absolute value graph makes a “V”-shaped figure. It consists of two parts: one with a negative slope and one with a positive slope. The point of their intersection is called the vertex. An absolute value graph is symmetrical, meaning that it can be folded in half on its line of symmetry.

An absolute value graph has a distinct V-shape. It is symmetric about the vertical line which passes through its vertex. The vertex of an absolute value function is the point at which the graph changes direction. Since the graph of y=|x-1|+1 changes direction at (1,1), this point is the vertex.

The simple interest for 4 years is Rs 960 and at the end of 4 years, the total amount in the bank account is Rs 2160.

Simple interest is calculated by multiplying the principal amount (initial deposit) by the interest rate and the number of years. In this case, the principal amount is Rs 1200 and the interest rate is 20% per annum (or 0.20) and the number of years is 4.

Simple Interest = Principal x Rate x Time

Simple Interest = 1200 x 0.20 x 4 = 960

So the simple interest for 4 years is Rs 960

To calculate the total amount at the end of 4 years, we add the simple interest to the original deposit.

Total Amount = Principal + Simple Interest

Total Amount = 1200 + 960 = 2160

So, at the end of 4 years, the total amount in the bank account is Rs 2160

Therefore, the simple interest for 4 years is Rs 960 and at the end of 4 years, the total amount in the bank account is Rs 2160.

Answer:

JK = 10 , JL = 14

Step-by-step explanation:

• opposite sides of a parallelogram are congruent

(6)

JK = ML , that is

3x - 2 = x + 6 ( subtract x from both sides )

2x - 2 = 6 ( add 2 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Then

JK = 3x - 2 = 3(4) - 2 = 12 - 2 = 10

• the diagonals of a parallelogram bisect each other

(7)

JL = 2 × JA = 2(2x - 1) = 4x - 2 ( substitute x = 4 )

JL = 4x - 2 = 4(4) - 2 = 16 - 2 = 14

P( X < 9.85 or X > 10.15 ) ≈ 0.3171 up to four decimal places.

P( X < 9.85 or X > 10.15 ) ≈ 0.0027 up to four decimal places.

The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of different outcomes, or how likely they are if we are unclear about how an event will turn out. Statistics refers to the study of occurrences subject to probability.

According to the question

a) Assuming that X is the random variable that takes the place of the number of defectives and has a normal distribution with a mean of 10 ounces and a standard deviation (σ) of 0.15.

The random variable's values deviate from the mean by 1, causing them to either exceed or fall short of (10 + 0.15) and (10-0.15)

= 10.15 or 9.85.

The following formula may be used to determine the likelihood that there will be either more or lesser defects than the range of 10.15 to 9.85:

P( X < 9.85 or X > 10.15 ) = 1 - P [tex](\frac{9.85-10}{0.15} < \frac{X-10}{0.15} < \frac{10.15-10}{0.15} )[/tex]

P( X < 9.85 or X > 10.15 ) = 1 - φ(1) - φ(-1)

Now we calculate the value of z for z = 1 and z = -1; we have: 0.841345 and 0.158655 respectively

P( X < 9.85 or X > 10.15 ) = 1 - (0.841345 - 0.158655)

P( X < 9.85 or X > 10.15 ) = 0.31713

P( X < 9.85 or X > 10.15 ) ≈ 0.3171 up to four decimal places.

b) It is possible to lower the process standard deviation to 0.05 by making modifications to the process design.

The following formula may be used to determine the likelihood that the number of defectives is either larger than 10.15 or lesser than 9.85:

P( X < 9.85 or X > 10.15 ) = 1 - P  [tex](\frac{9.85-10}{0.15} < \frac{X-10}{0.15} < \frac{10.15-10}{0.15} )[/tex]

P( X < 9.85 or X > 10.15 ) = 1 - φ(3) - φ(-3)

Now we calculate the value of z for z = 3 and z = -3; we have: 0.99865 and 0.00135 respectively

P( X < 9.85 or X > 10.15 ) = 1 - (0.99865 - 0.00135)

P( X < 9.85 or X > 10.15 ) = 0.00271

P( X < 9.85 or X > 10.15 ) ≈ 0.0027 up to four decimal places.

(c) What is the benefit of increasing the number of standard deviations from the mean for process control limits by minimizing process variation?

As we can see from the reduction from a to b above, the key benefit of minimizing process variance is that it will decrease the likelihood of receiving a defective item.

Answer:

An exponential function has the form y = ab^x, where a and b are constants and x is the independent variable (in this case, time).

Given the initial condition that there were 4 bacteria in the dish, we know that when x = 0, y = 4.

So we can set up the equation: 4 = a(b^0)

Given the condition that 5 hours later there were 972 bacteria in the dish, we know that when x = 5, y = 972.

So we can set up the equation: 972 = ab^5

We can now solve for b by dividing the two equations:

972/4 = ab^5/a(b^0) = b^5

b = (972/4)^(1/5)

With b calculated, we can substitute it into one of the equations to find a:

4 = a(b^0) = ab^0 = a

So the exponential function that satisfies the given conditions is:

y = ab^x = 4(b^x) = 4( (972/4)^(1/5)^x)

This function models the growth of bacteria in the Petri dish

I don't know exactly what the question was, but I'm guessing it's the bacteria growth rate.

You can use the formula

final amount of bacteria = (initial amount of bacteria)(bacteria growth rate)^number of hours

So,

972 = (4)(x)^5

then simplify this equation to solve for x

x=3

the amount of bacteria increased 3 times more every hour for 5 hours
