Answer from: KallMeh

Set 1

10 cm, 26 cm, 24 cm

Step-by-step explanation:

Set 1

10 squared + 24 squared = 26 squared

100 + 576 = 676

676 = 676

Set 2

4 squared + 2 squared = 6 squared

16 + 4 = 36

20 = 36

not equal to

Set 3

14 squared + 13 squared = 15 squared

196 + 169 = 225

365 = 225

not equal to

Set 4

10 squared + 20 squared = 30 squared

100 + 400 = 900

500 = 900

not equal to

Therefore Set 1 only makes a right angle

Answer from: silasjob09

The answer is Set 1,

this is because you can do Pythagoras' theorem and say that 10^2 + 24^2 must equal 26^2, so:

100 + 576 = 676

√676 = 26

And therefore Set 1 is a right-angled triangle because Pythagoras' theorem only works on right-angled triangles

Answer from: Quest

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

Answer from: Quest

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b): y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4 perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

Which equation represents a line perpendicular to the line shown on the graph?
