Determine if the statements below are true or false. (a) the area vector a of a flat, oriented surface is parallel to the surface. true false (b) if s1 is a rectangle with area 1 and s2 is a rectangle with area 2, then 2 f · da s1 = f · da s2 . true false (c) if s is the unit sphere oriented outward and f · da s = 0 then f (x, y,z) is perpendicular to x i + y j + z k at every point of s. true false

TRUE TRUE FALSE TRUE FALSE TRUE TRUE TRUE

Step-by-step explanation:

i can't see the picture : /

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
