Carlton is using the following data samples to make a claim about the house values in his neighborhood:House ValueA $100,000B $600,000C $650,000D $700,000E $900,000Based on the data, should Carlton use the mean or the median to make an inference about the house values in his neighborhood?He should use the median because there is an outlier that affects the mean.He should use the mean because there are no outliers that affect the mean.He should use the mean because it is in the center of the data.He should use the median because it is in the center of the data.
The option A "He should use the median because there is an outlier that affects the mean." is correct.
It is clear from the data that option E's house is much more expensive than those in the other options. A $9,00,000 price is therefore an outlier in this set of data.
In symmetrically distributed data, an inference is made using the mean. Due to the inclusion of an outlier, the data is not symmetrical. As a result, the mean won't accurately depict the data's centre. As a result, we shall refrain from drawing conclusions about the pricing of the residences using the mean.
Therefore, since the median is unaffected by outliers, we shall use it.
Therefore, since there is an outlier that influences the mean, we will utilise the median. The answer is (A).
Your sincere criticism is crucial for better outcomes.

A circular table has a diameter of 3 feet. Kristin is taping a piece of border around the edge of the table. Exactly how much border does Kristin need?
Exact length of border required by Kristin is calculated to be 9.42 ft.
This question can be solved using the concept of circumference of a circle.
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were expanded out and straightened out to a line segment, the circumference would be the length of the arc. The curve/arc length around any closed figure is more often referred to as the perimeter. The term "circumference" can also refer to the circle's actual location, which corresponds to a disk's edge. A sphere's circumference is equal to the length of any one of its great circles.
Circumference of a circle is given by 2πr.(r is the radius of the circle)
In the given question,
diameter= 3ft
radius= half times of diameter
radius= 1.5 ft.
Circumference= 2πr
= 2×3.14×1.5
=9.42 ft
Kristin will require 9.42 ft of border around the edge of the table.

In the diagram below lines p and r are parallel. Line s is a Transversal that is not perpendicular to lines p and r
which angle is not congruent to <5
(Geometry)
Answer: Any of the following angles are not congruent to angle 5.
angle 2angle 4angle 6angle 8The only exception being that if angle 5 is 90 degrees, then so are the remaining four angles shown above (in fact, all 8 angles are right angles).
========================================================
Explanation:
Angles 2 and 5 are supplementary since line p is parallel to line r. This means angle 2 and angle 5 add to 180 degrees. The two angles are only congruent if both are right angles (aka 90 degree angles); otherwise, they are not congruent angles.
Angle 2 = angle 4 because they are vertical angles. So because these two angles are congruent, and angle 2 does not have the same measure as angle 5, this consequently leads to angle 4 also not being the same measure as angle 5 (unless both are right angles).
Angle 2 = angle 8 because they are alternate interior angles. Following the same logic path as the last paragraph, we see that angles 8 and angle 5 aren't the same measure. Or we could note that angle 5 and angle 8 form a straight angle, so they must add to 180 degrees. The two angles are only congruent if they were 90 degrees each, or otherwise not congruent at all.
Similar logic can also show that angle 6 is not congruent to angle 5.
---------------------------
An alternative path is to find all the angles that are always congruent to angle 5 and they are...
angle 1 (corresponding angles)angle 3 (alternate interior angles)angle 7 (vertical angles)And everything else is not congruent to angle 5.
Diaz has a company car that allows him to drive up to 1,500 miles each month. He averages 28 miles each day.

Which of the following statements is true?
The remaining miles are 660 miles.
This month, Diaz drives 28 miles each day using the car allotted to him by his company.
But the company allows him to drive up to 1500 miles each month by his car.
To calculate the remaining miles that Diaz has not traveled this month, we have to use the formula m = 1500 - 28d, where d is the number of days in that particular month.
A month general consists of 30 days.
So, this month Diaz has traveled 28×30 miles = 840 miles ( using multiplication)
Therefore, the remaining miles(m) that Diaz has not traveled this month comes to 1500 - 840 = 660 miles.

How do you graph a slope of 3 4?
if the y-intercept is (0,5), you have:
y = (3/4)x + 5
How to slope a graph?To graph a line with a slope of 3/4, you can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.
Since the slope is 3/4, the equation of the line is y = (3/4)x + b.
To find the y-intercept, you can plug in the coordinates (0,b) into the equation. So if the y-intercept is (0,5), you have:
y = (3/4)x + 5
You can then plot the point (0,5) on the graph, and use the slope of 3/4 to find the next point by going up 3 and right 4.
Another way is to pick two points on the line and plot them, you can use the slope formula (rise over run) to find the next point on the line.

Un vendedor ambulante compra camisetas a 6 € y las vende a 11 €. ¿Cuántas camisetas debe vender para obtener una ganancia de 400 €?
Answer:
El vendedor ambulante debe vender 80 camisetas para obtener una ganancia de 400 €.
Step-by-step explanation:
La ganancia que obtiene el vendedor es el resultado de restar el costo total menos las ventas totales. El costo total es igual al costo por camiseta por el número de camisetas y las ventas totales son iguales al precio de venta por el número de camisetas vendidas, lo que se puede expresar de la siguiente forma:
x=11y-6y
x=5y, donde:
x es la ganancia
y es el número de camisetas
Dado que se quiere obtener una ganancia de 400, este valor sería x, y debes despejar y:
400=5y
y=400/5
y=80
De acuerdo a esto, la respuesta es que el vendedor ambulante debe vender 80 camisetas para obtener una ganancia de 400 €.

Por ejemplo: el chico ordenado / la chica artística
Answer:
The correct translation fo the sentences for each case is:
Una chica seria.El chico talentoso.Una chica extrovertida.El helado sabroso.Un libro gracioso.Step-by-step explanation:
In Spanish, the phrases regularly have the next order:
Article / Noun / AdjectiveBy this reason, in all of the phrases I put the adjective at the end, and the noun in the middle. By other side, you must pay attention that the adjective agree with the noun, how you can see in the answer, I show you how, when it's a masculine noun, finished in vowels as "o," the adjective finishes in a masculine form too ("o" in the exercises), by last, when the noun ends in a feminine form, the adjective finishes in a femenine form too (in the exercise you can see the noun and the adjective finishes in "a").
f(x) = -1/2x^2 + 3/2x - 2 I need to find the zeros
Answer:
{-1, 4}
Step-by-step explanation:
In the given f(x) = -1/2x^2 + 3/2x - 2
set f(x) = 0 and then multiply all the numeric terms by -2 to remove the fractions:
f(x) = -1/2x^2 + 3/2x - 2 = 0 => 1x^2 - 3x - 4 = 0
This factors into (x - 4)(x + 1) = 0, whose roots are {-1, 4}. These are the zeros.
