The length of a rectangle is 4 times its width. If the
perimeter of the rectangle is 90 feet, write an
equation in terms of w, the width of the rectangle.

Answer:

y=-4x-1

Step-by-step explanation:

x-4y=24

-x      -x

-4y=-x+24

Divide -4

y=-1/-4x-6

Simplify the slope.

y=1/4x-6

Perpendicular slope

m = 1/4

m = -4

The point is (-2,7)

-2 is the x intercept

7 is the y intercept

Slope Point Form is y-y1=m(x-x1)

Plug it in

y-7=-4(x+2)

Solve and put it into slope intercept form

y-7=-4x-8

 +7      +7

y=-4x-1

M+=108 is a technique to indicate a compound's molecular formula; it only contains simple numbers for each type of atom in a molecule and no structural information.

An organic chemical molecule that only contains hydrogen and carbon atoms is referred to as a hydrocarbon. Natural hydrocarbons are the building blocks of coal, natural gas, crude oil, and other significant energy sources. They burn easily and emit heat, water, and carbon dioxide when they are burned. As a result, hydrocarbons constitute a very efficient fuel source. The concerned hydrocarbon molecule contains 12 hydrogen atoms and 8 carbon atoms. The resulting chemical is C8H12. C8H12 is composed of one ring and two double bonds.

a = 5 and a = 4 are the sum of both digits, of either of two two-digit numbers.

What is square number in math?

This can also be solved algebraically. Let the 2 digits be a and b, going left to right.  The number itself is then

N = 10a + b.  And it's given that a + b = 9, and a2 - ab + b2 = 21.  Substitute for b = 9 - a, combine all terms of a2 and a, and you get

3a2 - 27a + 60 = 0.  Divide by 3

a2 - 9a + 20 = 0.  Factor

(a - 5)(a - 4) = 0.  So the roots are a = 5 and a = 4.

The actual numbers N are 54 and 45.

The digits can be changed since the equations including only a and b are symmetric. (If a = 5, then b must be 4; inverse)

The points X(6,7), Y(2,3), Z(4,1) can be plotted as given below. From the obtained graph ∠XYZ is the right angle.

The given coordinates are X(6,7), Y(2,3) and Z(4,1).

We need to classify ∠XYZ whether it is right, acute, or obtuse.

A cartesian plane or coordinate plane can be defined as a plane formed by the intersection of two coordinate axes that are perpendicular to each other. The horizontal axis is called the x-axis and the vertical one is the y-axis. These axes intersect with each other at the origin whose location is given as (0, 0). Any point on the cartesian plane is represented in the form of (x, y). Here, x is the distance of the point from the y-axis and y is the distance from the x-axis.

Now, X(6,7), Y(2,3), Z(4,1) can be plotted as given below:

All points X(6,7), Y(2,3), Z(4,1) have the positive x and y coordinates.

So, all the points X(6,7), Y(2,3) and Z(4,1) lie in the first quadrant.

From the graph, we can see at the two lines are perpendicular to each other.

The length of segment MN rounded to the nearest tenth is 6.7 units.

The distance formula used in finding the distance between two points is expressed as;

D = √( (x₂-x₁)² + (y₂-y₁)² )

Given the data in the question;

Point N(-1, 2)

Point M(-4,-4)

Plug these values into the above equation.

D = √( (x₂-x₁)² + (y₂-y₁)² )

D = √( ( (-4) - (-1))² + ( (-4) - 2)² )

D = √( ( -4 + 1 )² + ( -4 - 2)² )

D = √( ( -3 )² + ( -6 )² )

D = √( 9 + 36 )

D = √45

D = 3√5

D = 6.7 units

In the given question, we have 11 terms in Hours, So we get N = 11, and the formula can calculate the Median for the allotted Hours  [tex]\frac{n+1}{2}[/tex]

Since the Median is 6th term i.e.  we get Middle Quartile Q2 = 1300Hours

Q1 is the Lower quartile of the graph and the Median divides the graph into 8 equal parts. And we get the value of Q1 = 1100 Hours. Whereas, The upper quartile is the upper quarter. So, Q3 = 1400 Hours.

We have the formula to calculate the Interquartile range :

  IQR = Q3 - Q1

Putting values of Q3 and Q1 into the formula, We get :

         IQR = 1400 - 1100

Emily claims that a tree height of 43 inches is an outlier for the distribution.

What is the 1.5 IQR rule for outliers?

Add 1.5 to the interquartile range (IQR) (a constant used to discern outliers). The third quartile is increased by 1.5 times (IQR). Any figure above this is thought to be an outlier.

The starting and the end of the box in box plot are first and third quartile respectively.

From the given box plot it is clear that, Q₁ = 34  and Q₃ = 38

IQR = Q₃ -  Q₁

IQR = 38 - 34

IQR = 4

According to 1.5x IQR rule for outliers, all the data values lies outside the interval [ Q₁  - 1.5 × IQR , Q₃ + 1.5 × IQR ] are outliers..

Q₃ + 1.5 × IQR = 38 + 1.5(4)

Q₃ + 1.5 × IQR = 38 + 6

Q₃ + 1.5 × IQR = 44

We know that, 43<44.

Since, 43 is not greater than Q₃ + 1.5 × IQR  therefore, 43 is not an outlier and there is no evidence to support the claim.
