The radian measure of an angle theta is the length of the arc that subtended angle 2Pi
We can measure angles in two forms degrees or Radians.
Radian can be described as a measure of the angle subtended by a circular arc. It can be defined as the ratio of the arc length subtending angle to the radius of the circle.
One radian is the measure of the angle subtended by an arc that is equal to the radius of the circle.
Therefore, the radians measure an angle theta the length of the arc.
Θ =s/r ,
where theta is the angle subtended, s is the arc length and r is the radius of the circle.
We know that the 2π radians = 360 degrees.
That subtends the angle in a circle of radius 2Pi
Therefore, The radian measure of an angle theta is the length of the arc that subtended angle 2 Pi

How do you find the mean and standard deviation of a population distribution?.
The standard normal distribution (z distribution) is a normal distribution with a mean of 0 and a standard deviation of 1. Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z = (x-mean) / standard deviation.
In information, the standard deviation is a degree of the quantity of variation or dispersion of a fixed of values. A low standard deviation indicates that the values tend to be near the implied (additionally called the predicted price) of the set, whilst an excessive preferred deviation suggests that the values are spread out over a wider variety.
Popular deviation can be abbreviated SD, and is maximum commonly represented in mathematical texts and equations by means of the decrease case Greek letter σ (sigma), for the population standard deviation, or the Latin letter s, for the sample general deviation.
The standard deviation of a random variable, pattern, statistical population, statistics set, or possibility distribution is the square root of its variance. it's miles algebraically easier, even though in exercise less sturdy, than the common absolute deviation.

Writing linear equations given two points can be a useful skill when graphing linear equations.
Write a linear equation that passes through the given two points?To write a linear equation given two points, you need to first find the slope of the line. You can do this by finding the change in the y-value and dividing it by the change in the x-value. From there, you can use the slope to solve for the y-intercept and write the equation.For example, if the two points are (3, 4) and (0,5), you would find the slope by calculating the change in the y-value (5-4 = 1) and dividing it by the change in the x-value (0-3 = -3).The slope would then be 1/-3, which can be simplified to -1/3. To solve for the y-intercept, you can plug in one of the points and solve for b. In this case, you would plug in (3, 4) and solve for b, giving you b = 5. Now that you have the slope and y-intercept, you can write the equation as y = -1/3x + 5.y = -1/2xy = 5/3x + 5/3y = 3/5x + 1y = -1/2x - 2y = 6/5x + 5y = -4/4x - 8y = -3/5x - 7/5y = -2x - 4y = 5/6x + 7y = -1/2x + 4To learn more about linear equation refer to:

Kate has a Major Medical Plan with a 75/25 coinsurance and a deductible of $25. How much will she have to pay if she, not having met any of her deductible, visits the doctor and receives a bill for $125?
Kate will have to pay $56.25 out of pocket for her doctor visit.
The formula for calculating coinsurance is Coinsurance = (Cost of Service x Coinsurance Percent) / 100.If Kate has not met her deductible yet, she will need to pay the full $25 deductible plus 25% of the remaining bill.
The formula for calculating the amount Kate needs to pay is as follows:
Cost to Patient (C) = Deductible (D) + Coinsurance (C) * (Bill – Deductible) In this case, Kate would need to pay (125 x 25) / 100 = $31.25. The extra $25 is the deductible, which is the amount she must pay before her insurance kicks in.This amount is due immediately upon the visit, regardless of whether or not she has met her deductible So in total, Kate would have to pay $25 + $31.25 = $56.25.

The second term of a G.P is 6, and the fifth term is 48, find the common ratio and the 3rd term of the G.P.
Answer:
Common ratio = 2, Third term = 12
Step-by-step explanation:
ar⁴ = 48........ equation 1
ar = 6.......... equation 2
divide equation 1 by equation 2
r³ = 8
r = ³√8
r = 2
To get the third term we must first get the first term
Since ar = 6 and r = 2, then 2a = 6 and a = 3
3rd term = ar²
3 × 2² = 3 × 4 = 12
Answer:
r = 2 and a₃ = 12
Step-by-step explanation:
the nth term of a GP is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
given a₂ = 6 and a₅ = 48 , then
a₁r = 6 → (1)
a₁[tex]r^{4}[/tex] = 48 → (2)
divide both sides of (2) by (1) to eliminate a₁
[tex]\frac{a_{1}r^{4} }{a_{1}r }[/tex] = [tex]\frac{48}{6}[/tex] ( cancel r and [tex]r^{4}[/tex] by r )
r³ = 8 ( take cube root of both sides )
r = [tex]\sqrt[3]{8}[/tex] = 2
substitute r = 2 into (1) and solve for a₁
a₁ × 2 = 6 ( divide both sides by 2 )
a₁ = 3
a₂ = a₁ × r = 3 × 2 = 6
a₃ = a₂ × 3 = 12

The temperature changed at a constant rate between noon and 3:30 p.m. At what rate, in degrees F per hour, did the temperature change between noon and 3:30 p.m.? Show your work or explain your answer.
Answer:
To solve this problem, we need to calculate the change in temperature between noon and 3:30 p.m. and then divide that by the number of hours between noon and 3:30 p.m.
Let's say the temperature at noon was 70 degrees F and the temperature at 3:30 p.m. was 75 degrees F.
The change in temperature between noon and 3:30 p.m. is 75 - 70 = 5 degrees F.
The number of hours between noon and 3:30 p.m. is 3.5 hours.
Therefore, the rate of change in temperature between noon and 3:30 p.m. is 5 degrees F / 3.5 hours = 1.43 degrees F per hour.

What is the slope and y-intercept of the function y =- 5x 4?.
Due to the absence of an x in the issue, the y-intercept is -4. At the conclusion, it stands on its own and directs you to begin at (0,-4). The slope is -5/1 because the slope of the equation is toward the value of x in the equation.
How steep a slope does Y = - 5x 4 have?y = 5x - 4 has a 5 slope. The line's equation, y = 5x - 4, is expressed in the form y = mx + b, as you can see. It is therefore in slope-intercept form. When a line's equation is written in slope-intercept form, we may determine that the slope of the line equals m, the x-coefficient.
How do you calculate a function's slope and y-intercept?Y = mx + b, where m denotes the slope and b the y-intercept, is how the equation of the line is expressed in the slope-intercept form. We can see that the y-intercept of the line in our equation, y = 7 x + 4, is 4.
