Step-by-step explanation:
Remember that when solving for the median, Order the numbers from least to greatest. The middle number in the set is your median:
1 , 2 , 4 , 4, 6
4 is your answer.
~
Here we are given with some numbers:
• 1, 2, 4, 6, 4
We have to find the median. For this, we have to arrange the data in ascending or descending order. So, let's arrange it in required order.
➝ 1, 2, 4, 4, 6
As the total no. of numbers is 5, the median will be the middle term that is 4. Because when the number of terms is odd, then median is n/2 and when the number of terms is even, the median is n/2 + n + 1/2 /2 th term.
Correct answer is 4.

An investment of $500 earns interest at an annual interest rate of 13%. The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years. Write an equivalent equation that displays the effective monthly interest rate. A) B = 500(1.10)12t B) B = 500(1.12)12t C) B = 500(1.010)12t D) B = 500(1.012)12t
Answer: C) [tex]B= 500(1.101)^{12t}[/tex]
Step-by-step explanation:
Given : The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years.
For monthly interest , Rate = [tex]\dfrac{r}{12}[/tex]
Time = 12 t [ 1 year = 12 months ]
As r = 0.13 , so rate = [tex]\dfrac{0.13}{12}\approx0.010[/tex]
Now, the equation will be :
[tex]B=500 (1+0.101)^{12t}[/tex]
[tex]\Rightarrow\ B= 500(1.101)^{12t}[/tex]
Correct option : C) [tex]B= 500(1.101)^{12t}[/tex]
what is angle D? i don't know how to do the math due to being absent on a friday
Answer:
∠ D = 110°
Step-by-step explanation:
Assuming the quadrilateral is a parallelogram.
• Consecutive angles sum to 180° , then
∠ B + ∠ C = 180 , that is
5x + 3x + 4 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
Then
∠ B = 5x = 5 × 22 = 110°
• Opposite angles are congruent
∠ D = ∠ B = 110°

On the ceiling of a cavern, a stalactite grows downward 0.01 inches per year. Ten feet directly below on the cavern's floor, a stalagmite grows upward 0.005 inches per year. How many years will it take them to meet? Express your answer to the nearest hundredth. Your answer
Answer:
666.66 years
Step-by-step explanation:
In this scenario, we need to find at what year both of the stalagmite crystals are at the exact elevation in the cave. So we need an algebraic formula to calculate this. Since the crystal in the ceiling is at a height of 10 feet (height of the cave) and is growing down we need to subtract its growth from its starting position of 10ft. The second crystal is starting at an elevation of 0 and growing upward so we simply need to chart its growth and equal both equations together to find its meet-up point. In this algebraic equation, x will equal the number of years that we need to find.
[tex]10 - 0.01x = 0.005x[/tex] ... add 0.01x to both sides.
[tex]10 = 0.015x[/tex] ... divide both sides by 0.015
[tex]666.66 = x[/tex]
Finally, we can see that both crystals will meet-up after 666.66 years. If we plug this value into the equation we see that the crystals will meet-up at a point 3.33 ft above the cave floor.

Calculate the bearing of Y from X
Answer:
bearing of Y from X is 074°
Step-by-step explanation:
the bearing of Y from X is the clockwise measure of the angle from the northline N to Y , that is
180° - 106° = 74°
the 3- figure bearing of Y from X is 074°
The value of the bearing of Y from X will be 74°.
What is Supplementary angle?
The sum of two or more angle is 180 degree then the angle is called the Supplementary angle.
Given that;
The value of measure of ∠X = 106°
Now,
Since, The value of the bearing of Y from X will be calculated as;
∠X + ∠Y = 180°
106° + ∠Y = 180°
∠Y = 180° - 106°
∠Y = 74°
Thus, The value of the bearing of Y from X will be 74°.

A membership sales person at a gym is given a choice of two different compensation plans. One plan offers a weekly salary of $300 plus a commision of $15 for each membership sold. The other plan offers no salary but pays $30 commission on each membership sold. How many memberships must the salesperson sell to make the same amount of money under both plans? FAST PLS
Answer: The salesperson must sell 20 memberships to make the same amount of money under both plans.
Step-by-step explanation:
Let x be the number of memberships.
In first plan,
Weekly salary of $300 plus a commission of $15 for each membership sold.
i.e. Earning (weekly) = 300+15x
In second plan,
The other plan offers no salary but pays $30 commission on each membership sold.
i.e. earning = 30x
According to the question, when [tex]300+15x=30x[/tex]
[tex]\Rightarrow\ 300=30x-15x\\\\\Rightarrow\ 300=15x\\\\\Rightarrow\ x=\dfrac{300}{15}\\\\\Rightarrow\ x=20[/tex]
Hence, the salesperson must sell 20 memberships to make the same amount of money under both plans.
Aplicando el teorema de Tales elige la opción que determine la altura de una torre que proyecta una sombra de 14 m, tomando en cuenta que Kevin tiene una estatura de 1.75 m y proyecta una sombra de 3.5m
Utilizando el teorema, veremos que la altura de la torre es 7 metros.
¿Cual es la altura de la torre?
El teorema de Tales nos dice que para triangulos similares, la razon entre los catetos debe ser igual.
Esto significa que la razon entre la altura y el largo de la sombra de un objeto debe ser una constante.
Sabemos que Kevin tiene una estatura de 1.75m y proyecta una sombra de 3.5m
El cociente es:
3.5m/1.75m = 2
Es decir, la sombra tiene una longitud de dos veces la altura.
Entonces si la sombra de la torre es de 14m y la altura es h, tendremos:
14m/h = 2
h = 14m/2 = 7m
La altura de la torre es de 7 metros.

Proof using Discrimant:
[tex]3 { x}^{2} - 2x + \frac{1}{3} = 0[/tex]
The discrimant is
[tex] \sqrt{ {b}^{2} - 4ac} [/tex]
B is -2, A is 3 and C is 1/3 so we get
[tex] \sqrt{ {2}^{2} - 4( 3)( \frac{1}{3}) } [/tex]

Since the discrimant equal zero, there is one real distinct zero.
This zero will also have a multiplicity of 2, so the zero is technically equal to each other.
To get better at solving, let solve for zero.
[tex]3 {x}^{2} - 2x + \frac{1}{3} = 0[/tex]
[tex]3( {x}^{2} - \frac{2}{3} x + \frac{1}{9} )[/tex]

Answer:
Exact volume = 30,000 + 5,000pi cubic mm
Approximate volume = 45,700 cubic mm
========================================================
Explanation:
Break the figure into two pieces.
The top part is a half-cylinder with radius r = 20/2 = 10 mm and height h = 100 mm.
The volume of this half-cylinder is
V = 0.5*(full cylinder volume)
V = 0.5*pi*r^2*h
V = 0.5*pi*10^2*100
V = 5000pi
This is exact in terms of pi.
The lower part is a 20 mm by 100 mm by 15 mm rectangular block. It has volume of length*width*height = 20*100*15 = 30,000 cubic mm.
---------
We'll add the two volumes found earlier to get the overall volume.
The total exact volume is 30,000+5,000pi cubic mm.
To get an approximation, you can use something like pi = 3.14
30000+5000pi = 30000+5000*3.14 = 45,700 cubic mm is the approximate volume when using pi = 3.14

Answer:
follow directions. h represents a horizontal shift, + shifts to the right. k represents a vertical shift, + shifts up.
Step-by-step explanation:
Modern math instruction often tends toward giving you a task that is intended to help you discover for yourself particular mathematical relationships. This is one such task.
Here, you're intended to follow the instructions: using the technology provided (a graphing tool at the link) to discover the effect of changing the values of h and k in the function.
__
The first attachment shows plots from my graphing tool for different values of h. The red curve shows h=-2, the blue curve shows h=0, and the green curve shows h=1. If you look for the marked upward zero crossing, you see that it is unshifted for h=0, shifted left 2 units for h=-2, and shifted right 1 unit for h=1.
You are intended to conclude that the value of h represents the amount by which the function is shifted to the right.
__
The second attachment shows plots from my graphing tool for different values of k. As before, the red curve shows k=-2, the blue curve shows k=0, and the green curve shows k=1. Again, the upward zero crossing has been marked to show the effect. For k=-2, the curve is shifted down 2 units; for k=1, it is shifted up 1 unit. There is no shift when k=0.
You are intended to conclude that the value of k represents the amount by which the function is shifted upward.
__
If you do what the problem tells you to do, you can see these effects in real time, watching changes as they occur. You are expected to describe them. Only you know what the "vocabulary from 9/21-922" is.

Math instruction builds on previously seen concepts. This is not a subject in which you can be successful adopting the strategy of "test and forget." You're better off with a strategy of "learn it thoroughly and remember," working as many problems as necessary to keep it fresh in your mind.

Solve for the value of x in the figure below.
Solve for the value of y in the figure below.
Answer:
x=37
y=125
Step-by-step explanation:
97+28+x+18=180 (sum of the interior angles of a triangle is 180)
143+x=180
x=180-143
x=37
y+x+18=180 (sum of the angles on a straight line is 180°)
y+37+18=180
y+55=180
y=180-55
y=125
or
y=97+28(exterior angle of a triangle= 2 interior opposite angles)
y= 125

Answer:
D. the product of x and a factor not depending on x
Step-by-step explanation:
The equation for the given expression is:
[tex]x (2y+7z)^{2}[/tex]
According to the expression, there are two factors:
the first factor is x, and
the second factor is [tex](2y+7z)^{2}[/tex]
Since, the second factor do not contain x, therefore it is independent of x.
Hence, the expression for the given equation will be the product of x and a factor not depending on x.
