Mathematics

Lets use this set of data as an example:
2,2,3,3,3,3,4,4,5

Median is the data number that is in the middle of all of the numbers when arranged from least to greatest.
The median would be 3 since its in the middle. THINK: Median=Medium

Range is the highest number minus the lowest number. This is easy.
5-2=3
So the range is 3.

The mode is the number that you see the most often. 3 is the most since there are four 3s. There can be more than one mode or even no mode. THINK: Mode=Most

The mean is all of the numbers added together and then divided by the number of numbers.
2+2+3+3+3+3+4+4+5= 29
29 divided by 9 = 3.2222222222(repeated)
The mean can also be called the average.

I hope this helps!!!

A kite is stuck in a 36-ft tree. If the angle of elevation from the kite and the ground is 12, find the length of the kite.

yanalaym [24]

Answer:

173.15 ft.

Step-by-step explanation:

Please find the attachment.

Let L be the length of kite.

We have been given that a kite is stuck in 36-ft tree. The angle of elevation from the kite and the ground is 12.

We can see from our attachment that kite and tree form a right triangle. height of tree is opposite of angle of elevation and length of kite is hypotenuse.

Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use sine to find the length of kite.

$sin(12)=\frac{36}{L}$

$L=\frac{36}{sin(12)}$

$L=\frac{36}{0.207911690818}$

$L=173.1504364105882792\approx 173.15$

Therefore, the length of kite is 173.15 ft.

Omar grouped the terms and factored the GCF out of the groups of the polynomial 3x3 – 15x2 – 4x + 20. His work is shown.

Phoenix [80]

Answer:

2nd option

Step-by-step explanation:

Given

3x³ - 15x² - 4x + 20

step 1 ( group the first/second and third/fourth terms )

(3x³ - 15x² ) + (- 4x + 20)

step 2 ( factor each group )

3x² (x - 5) - 4(x - 5) ← note factor of - 4 ( not + 4 )

step 3 ( factor out (x - 5) from each term )

(x - 5)(3x² - 4)

Express the given terminating decimal as a quotient of integers. if possible, reduce to lowest terms. 0.66

taurus [48]

.66 is 66 out of 100. "out of" means divide

66/100
We can reduce this by dividing each number by the same amount - 2

33/50

How to find area of parallelogram with coordinates of verticles?

ExtremeBDS [4]

You find a parallelogram area by this formula:
$A=b\cdot h$
Where b is its base and h, its height.
You get b's value applying distance between two points formula.
If A and B points form the base:
$A(x_1,y_1)\;\;\;\;B(x_2,y_2) \\ \\ 
d_{AB}= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} =b$

And h is the perpendicular distance between both bases.

If Josh invests $500 in a 5-year fixed interest savings bond that pays 5% per annum, how much will his entire investment be wort

gizmo_the_mogwai [7]

Answer:

$638.14

Step-by-step explanation:

Our equation is $p*(1+x)^{t}$ , with p being the starting amount, x being the interest rate, and t being the time. Plugging our variables in, we get

$500*(1+0.05)^{5}$ = around 638.14
