8 0

This formula is used to find the median in a group data which is located in the median class. Median, m = L + [ (N/2 – F) / f ]C

L means lower boundary of the median class N means sum of frequencies F means cumulative frequency before the median class.

Hope this helps :))

50 POINTS PLEASE HELP

Answer:

$perimeter= 5\sqrt{15} + 5\sqrt{5}$

Step-by-step explanation:

Given ,

A right angle triangle ΔABC with right angle at C and ∠A=30° and AC=5√5 units .

Let ∠A=A,∠B=B∠C=C and AC=b,BC=a,CA=b .

Implies perimeter of triangle = a+b+c .

now

$tanA=\frac{a}{b} \\\a=b*tanA\\a= 5\sqrt{5} *tan30^0\\a=\frac{5\sqrt{5}}{\sqrt{3}}$

and

$cosA=\frac{b}{c} \\\c=\frac{b}{cosA} \\c=\frac{10\sqrt{5}}{\sqrt{3} }$

implies ,

$perimeter = \frac{5\sqrt{5}}{\sqrt{3}} + 5\sqrt{5} +\frac{10\sqrt{5}}{\sqrt{3} }\\perimeter= 5\sqrt{15} + 5\sqrt{5}$

Answer:

slope = - 3 y-intercept = 36

Step-by-step explanation:

12x + 4y = 144 , will allow this to be done.

so 4y = - 12x + 144

now dividing both sides of the equation by 4 will give

y = - 3x + 36 , which is now in the required form

slope = - 3 and y-intercept = 36
