The Pythagorean Theorem is what you probably mean. It is basically to solve for the sides of a triangle. The equation is a^2+b^2=c^2. Plug in at least two of the variables and you will get any side.

I believe you are asking about the Pythagorean theorem? If you are, here's what it is:
In mathematics, the Pythagorean theorem, aka Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It says that the square of the hypotenuse (the side opposite the right angle) is equivalent to the sum of the squares of the two other sides.

An incomplete distribution is given below:Variable You are given that the median value is 70 and the total number of items is 20

expeople1 [14]

Answer:

The missing frequencies are x = 8 and y = 43.

Step-by-step explanation:

Median Value =70

Then the median Class =60-80

Let the missing frequencies be x and y.

Given: Total Frequncy = 200 , Median = 46

$\left|\begin{array}{c|ccccccc}Value&0-20&20-40&40-60&60-80&80-100&100-120&120-140\\Frequency&12&30&x&66&y&27&14\\$Cumu.Freq&12&42&42+x&108+x&108+x+y&135+x+y&149+x+y\end{array}\right|$

From the table

$\sum f_i =149+x+y$

Here, n = 200

n/2 = 100

Lower Class Boundary of the median class, l=60

Frequency of the median class(f) =66

Cumulative Frequency before the median class, f=42+x

Class Width, h=10

$Median = l + \dfrac{\dfrac{n}{2} - c.f }{f} \times h$

$70 = 60+ \dfrac{100- 42+x }{66}\times 10\\70 = 60+ \dfrac{58+x }{66}\times 10\\70-60=\dfrac{58+x }{66}\times 10\\10*66=10(58+x)\\58+x=66\\x=66-58\\x=8$

200=149+x+y

200=149+8+y

y=200-(149+8)

y=43

Hence, the missing frequencies are x = 8 and y = 43.

3x+8=15 find try the value of x

dimaraw [331]

Answer:

x = 7/3

Step-by-step explanation:

To find the of x, isolate it from the other numbers (moving everything to the other side)

What you do to one side, you must do to the other:

3x + 8 = 15

3x + 8 - 8 = 15 - 8 (subtract 8 on both sides to rid of the "+ 8")

3x = 7

3x/3 = 7/3 (divide by 3 on both sides to rid of the 3 attached to "x")

x = 7/3
