What is median?The median is the value in the middle of a data set, which indicates that 50% of the data points have a value less than or equal to the median, and 50% have a value greater than or equal to the median. The median is the number in the middle of a set of numbers. The median represents the 50th percentile of the set of numbers. In other words, the median is the value in the center of a set of numbers where half are less than the median and half are more than the median.

Graph the line y = 6x + 8
Answer:
The answer is in the explanation
Step-by-step explanation:
I hope this helps you
Write the equation using the table and graph pictured above
(Hint: this is a 2 step equation )
Answer:
y = -2x + 12
Step-by-step explanation:
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
I will use the first point (1, 10) and the last point (5, 2)
Plug in these values:
(2 - 10) / (5 - 1)
Simplify the parentheses.
= (-8) / (4)
Simplify the fraction.
-8/4
= -2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the last point (5, 2). Plug in the x and y values into the x and y of the standard equation.
2 = -2(5) + b
To find b, multiply the slope and the input of x(5)
2 = -10 + b
Now, add 10 to both sides to isolate b.
12 = b
Plug this into your standard equation.
y = -2x + 12
This is your equation.
Check this by plugging in the other point you have not checked yet (1, 10).
y = -2x + 12
10 = -2(1) + 12
10 = -2 + 12
10 = 10
Your equation is correct.
Hope this helps!

Christopher's backyard is in the shape of a trapezoid. The bases of his backyard are 30 and 40 feet long. The height is 8 feet long. What is the area of Christopher's backyard.
the formula for area of a trapezoid is 1/2h•(b+b)
so let's plug in the numbers
1/2h•(70)=525
so divide both sides by 70
1/2h=7.5
now divide both sides by 0.5
h=15
so the area is 150.

Terri gets most of her exercise by walking briskly. Last year she walked an average of 4.2 miles per day with a standard deviation of 1.2 miles per day. April swims for exercise last year she swam for a mean of 40 minutes per day with a standard deviation of 8 minutes per day. For the new year, both girls have resolved to exercise more. In January Terri walked an average of 6 miles per day while April swam for an average of one hour per day. Which girl is off to a better start relation to their results from the previous year?
Terri walked in her own 93rd percentile, while April swam in her own 99th percentile. April is off to a slightly better start.
En una jornada cultural los grupos de 3.° de ESO van a grabar un cortometraje y un clip musical. Al principio se inscribió para el corto el triple de alumnos que para el clip. A última hora, 5 alumnos se cambian del corto al clip y ahora el número de alumnos para el clip es la mitad que para el corto. ¿Cuántos están ahora en cada actividad?
Respuesta:
20 estudiantes
Explicación paso a paso:
Dejar :
número de estudiantes que firmaron para el clip = x
Número de estudiantes que firmaron para cortometraje = 3x
En el último minuto ;
Se convierte en cortometraje; 3x - 5 y el clip se convierte en; x + 5
Por eso ; la ecuación se convierte en;
x + 5 = 1/2 (3x - 5)
x + 5 = 1,5 x - 2,5
x - 1,5x = - 2,5 - 5
- 0.5x = - 7.5
x = 7,5 / 0,5
x = 15
Por lo tanto ;
Cortometraje: 1/2 (3x - 5)
1/2 (3 (15) - 5))
1/2 (45 - 5)
1/2 (40)
= 20
Por tanto, hay 20 alumnos en cada actividad.

Given:
The figure of two quadrilaterals.
In [tex]ABCD,AB=18,BC=20,CD=22,AD=24[/tex]
In [tex]EFGH,EF=27,FG=30,GH=34, EH=36[/tex]
To find:
Whether the figures are congruent, similar or neither.
Solution:
Ratio of corresponding sides are:
[tex]\dfrac{AB}{EF}=\dfrac{18}{27}[/tex]
[tex]\dfrac{AB}{EF}=\dfrac{2}{3}[/tex]
Similarly,
[tex]\dfrac{BC}{FG}=\dfrac{20}{30}[/tex]
[tex]\dfrac{BC}{FG}=\dfrac{2}{3}[/tex]
[tex]\dfrac{CD}{GH}=\dfrac{22}{34}[/tex]
[tex]\dfrac{CD}{GH}=\dfrac{11}{17}[/tex]
And,
[tex]\dfrac{AD}{EH}=\dfrac{24}{36}[/tex]
[tex]\dfrac{AD}{EH}=\dfrac{2}{3}[/tex]
Clearly, [tex]\dfrac{AB}{EF}=\dfrac{BC}{FG}=\dfrac{AD}{EH}\neq \dfrac{CD}{GH}[/tex].
All corresponding sides are not proportional.
Therefore, the figures are neither similar nor congruent. Hence, third option is correct.

Answer:
[tex]V=868.13\ ft^3[/tex]
Step-by-step explanation:
Given that,
The side length of the base of the pyramid, a = 14.1 ft
The height of the pyramid, h = 13.1 ft
We need to find the volume of the pyramid. The formula for the volume of the square base pyramid is given by :
[tex]V=\dfrac{a^2h}{3}[/tex]
Put all the values,
[tex]V=\dfrac{(14.1)^2\times 13.1}{3}\\\\V=868.13\ ft^3[/tex]
So, the volume of the pyramid is equal to [tex]868.13\ ft^3[/tex].

Answer:
22.50%
Step-by-step explanation:
Rate of return = ( Return on stocks / price at which it is bought) x 100
Return on stocks = (price at which it is sold - price at which it is bought )
Price at which 20 stocks are bought = 20 x 20 = $400
Return = $490 - $400 = $90
($90 / $400) x 100 = 22.50%
For which equation does it make the most sense to solve by using the zero product property? 4x2−2=15 2x2+2x−9=0 x² + 11x +30 = 0 x² + 2x = 119
Answer:
It makes more sense to apply the zero product property on x² + 11x + 30 = 0.
Step-by-step explanation:
The zero product property simply states that if ab = 0, then a = 0 or b = 0 or both are zeros.
Given 4x² – 2 = 15, 2x² + 2x – 9 = 0, x² + 11x + 30 = 0, x² + 2x = 119; let's see which of the above is easiest to apply the zero product property.
1. 4x² – 2 = 15
4x² – 2 – 15 = 0
4x² – 17 = 0
It's not so easy to express the result as a product equal to zero.
2. 2x² + 2x – 9 = 0
This is not factorisable easily and can't be expressed as a product equal to zero easily.
3. x² + 11x + 30 = 0
This is factorisable easily. On factorising we have:
x² + 5x + 6x + 30 = 0
(x + 5)(x + 6) = 0. The zero product property can be applied here easily since x = 5 or x = 6 or both.
4. x² + 2x = 119
x² + 2x – 119 = 0
This is not easily factorisable and cannot be expressed easily as a product equal to zero.
Therefore, it makes more sense to apply the zero product property on
x² + 11x + 30 = 0

Answer:
B. [tex]A(h) =3h^3 -h[/tex]
Step-by-step explanation:
Given is the figure of a trapezoid with following descriptions.
[tex] b_1=2h^2 +2[/tex]
[tex] b_2 =2h^2 +2+ 2h^2-6=4h^2 - 4[/tex]
[tex] height = h[/tex]
Now, by formula of area of trapezoid, we have:
[tex]A(h) =\frac{1}{2} (b_1+b_2)h[/tex]
[tex]A(h) =\frac{1}{2} (2h^2 +2+4h^2 - 4)h[/tex]
[tex]A(h) =\frac{1}{2} (6h^2 -2)h[/tex]
[tex]A(h) =\frac{1}{2} (6h^3 -2h)[/tex]
[tex]A(h) =\frac{1}{2} \times 2(3h^3 -h)[/tex]
[tex]A(h) =(3h^3 -h)[/tex]
[tex]A(h) =3h^3 -h[/tex]

Andre earns $4,000 a month at his new job in order to track his spending and saving he created a monthly budget. Andre divided his income into five categories and created the following circle graph to represent the budget he created for himself use this circle graph to answer the following questions.
a) Andre is planning on renting a new apartment but he wants to stay within his Budget on rent and the utilities. Andre is looking for an apartment the apartment cost $1,450 per month plus $250 for utilities will this apartment fit with an Andres budget? explain your reasoning
b) how much more money does Andre budget for savings than for groceries and utilities? write answer as a dollar amount
Answer:
If Andre plans on staying within his budget, he should choose Apartment 1.
Step-by-step explanation:
Apartment 1: $1100 rent + $250 utilities = $1350 Total Monthly
Apartment 2: $1350 rent + $100 utilities = $1450 Total Monthly
Andre can spend up to $1320 on rent & $320 on utilities, totaling at $1640. In this situation, Andre needs to save as much money as possible. Either on one of these apartments stay below the budget for monthly cost, but Apartment 2's rent goes $30 higher than his budget allows. In the end, this makes apartment 1 the best option for rent, utilities, and ultimate cost.
If Andre plans on staying within his budget, he should choose Apartment 1.
Tamia uses 9.9 pints of white paint and blue paint to paint her bedroom walls. 1/4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
7.425 pints
Step-by-step explanation:
Given that Tamia uses white and blue paint and 1/4 of the amount is white paint then the fraction of blue paint
= 1 - 1/4
= 3/4
Given that the total quantity of paints is 9.9 pints, the number of blue pints used to paint her bedroom walls
= 3/4 * 9.9
= 29.7/4
= 7.425 pints
