One of the same side interior angles of two parallel lines is 20* less than the other same side interior angle. Find the measures of the two angles
Answers
The measure of both the angles will be x = 80° and y = 100°.
What is Parallelogram? What are parallel lines?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. Two lines are said to be parallel if they have same slope. These lines never intersect each other and have no common point of intersection.
Given is the same side interior angles of two parallel lines is 20° less than the other same side interior angles.
Same side interior angles are supplementary, we can write -
x + x + 20 = 180
2x = 160
x = 80°
Other angle will be -
y = x + 20 = 100°
y = 100°
Therefore, the measure of both the angles will be x = 80° and y = 100°.

what would happen to the width of a confidence interval if the size of the population being sampled was doubled, from 25 million to 50 million?
Answers
50 million people instead of 25 million people make up the population. The degree of assurance is reduced from 95% to 90%.
What is confidence interval?
A confidence interval in frequentist statistics is a range of estimates for an unknown parameter. A confidence interval is calculated at a specified degree of confidence; the most popular level is 95%, but other levels, such 90% or 99%, are occasionally used.
Because the standard error is reduced as sample size increases, confidence intervals are narrower.
Therefore, we may state that when the population standard deviation rises, the width of the confidence interval will also rise.
Hence, 50 million people instead of 25 million people make up the population. The degree of assurance is reduced from 95% to 90%.

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 3 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
The slope of the line we want to find will be the negative reciprocal of this slope, which is -4/3
Slope m = -4/3
Now , the equation of line is y - y₁ = m ( x - x₁ )
y - 3 = ( -4/3 ) ( x - 0 )

a worn, poorly set-up machine is observed to produce components whose length x follows a normal distribution with mean 14 centimeters and standard deviation 3 centimeters. find the probability that the length of a component lies between 19 and 21 centimeters. round your answer to four decimal places.
Answers
The probability that the length of a component lies between 19 and 21 centimeters is 0.0376.
What is probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Given:
Population mean, µ = 14
Population standard deviation, σ = 3
Probability that the length of a component lies between 19 and 21 centimeters
= P(19 < X < 21)
= P( (19 - 14) / 3 < (X - µ) / σ < (21 - 14) / 3)
= P(1.67 < z < 2.33)
= P(z < 2.33) - P(z < 1.67)
Using excel function:
= NORM.S.DIST(2.33,1) - NORM.S.DIST(1.67,1)
= 0.9901 - 0.9525
= 0.0376
Hence, the probability that the length of a component lies between 19 and 21 centimeters is 0.0376.

A.) Give a linear equation in the form Cmn + b that gives the total cost, C, to produce n of these toys Preview
B.) The total cost to produce n 3000 toys is S
C.) With $32500, a total of toys can be produced.
Answers
a)The linear equation is C=25n + 2500 to produce n 3000 toys, b) The total cost to produce 3000 toys is $77,500, c) With $32500, a total of 1200 toys can be produced in Pinwheel Industries.
What is meant by the term linear equation?An equation is a mathematical statement with an equal symbol (=) between the algebraic expression. Equations with a degree of one are called linear equations. It is the straight line's equation. Whenever values are substituted for the unknown values in linear equations, the solutions produce values that make the equation true. Since there is only one variable, there is only one solution. For instance, the equation x + 2 = 0 has just one solution, which is x = -2. In the case of the two-variable linear equation, however, the solutions are determined as the Cartesian coordinates of a point on the Euclidean plane.
The three different types of linear equations are: 1) Standard Form
2) The slope intercept form
3)Point Slope Form
How to solve?
A) Linear equation y=mx+b,
C (total cost) = y and n (number of toys) =x.
C=25n + 2500
B) Put n=1750
C= 25(3000) + 2500
C= $77,500
C)
32500= 25n +2500

if an open rectangular box is to have a fixed volume v, what relative dimensions will make the surface area a maximum
Answers
Relative dimensions which will make the surface area a maximum is
x=y = \sqrt{area/3 }
z = 1/2( \sqrt{area/3 })
Volume = 2xh
Let the box have dimensions x,y,z>0.
The surface area is A=xy+2xz+2yz
The volume is V=xyz
The Lagrangian is L=V−λ(A−constant)=xyz−λ(xy+2xz+2yz−constant).
∂L∂x=yz−λ(y+2z)=0
∂L∂y=xz−λ(x+2z)=0
∂L∂z=xy−λ(2x+2y)=0
Hence, λ=yzy+2z=xzx+2z=xy2x+2y
On cross multiplication,
xyz+2yz2=xyz+2xz2which implies x=y.
Cross-multiplying the middle and the right expressions ,2x2z+2xyz=x2y+2xyzwhich implies z=12y.
So, optimal volume with fixed surface area is to have the width and the depth equal and the height to be half the width and depth.
To find x,y,z given a fixed surface area Area one would use x=y=2z in the equation
Area=xy+2xz+2yz=x2+x2+x2 so
x=y = \sqrt{area/3 }
z = 1/2( \sqrt{area/3 })
Volume is a measurement of three-dimensional space that is occupied. Numerous imperial units or SI-derived units, such as the cubic metre and litre, are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship.

Monica deposits $200 into a savings account that pays a simple interest rate of 3.7%. Paul deposits $300 into a savings account that pays a simple interest rate of 2.9%. Monica says that she will earn more interest in one year because her interest rate is higher, is she correct? justify your response.
Answers
Paul earns more interest than Monica does.
What is simple interest?Simple interest can be defined as a form of interest in which the percent rate is applied on the same principal for a given period of time.
Given that,
Money deposited by Monica is $200 at simple interest of 3.7%.
Money deposited by Paul is $300 at simple interest of 2.9%.
The expression to calculate simple interest is given as,
(P × r × t)/100
Substitute the corresponding values to obtain the simple interest for both cases as follows,
Interest gained by Monica is (200 × 3.7 × 1)/100 = $7.4.
Interest gained by Paul is (300 × 2.9 × 1)/100 = $8.7.
Hence, monica is not correct as the interest earned by Paul is greater than that of monica.

Answers
The equation which is equivalent to 60% of 25 is x = 0.6 * 25
1. Equivalent equations: Equivalent equations are algebraic equations that are having identical roots or solutions. By adding or subtracting the same number or expression to both side of an equation we get an equivalent equation. Also by multiplying or dividing both sides of an equation by the same non zero number we get equivalent equation.
2. How to find equivalent equation : Steps to find weather the equations are equivalent are:
Distribute the coefficients Combine any like term on both side.Arrange the term in same order.If all the terms in two expressions are same then the equations are equivalent.An equation is used to show the relationship between variables, numbers.
Let x represent the value of 60% of 25. Hence:
