Answer:
N = 1680
Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
Step-by-step explanation:
Given the word 'champion' which is an 8 distinct Letter word. The number of 4 letter groupings that could be formed from it can be given by the permutation since in this case order of letters are important.
The number of distinct 4 letter groupings can be given as;
N = nPr = 8!/(8-4)!, where n= 8 and r = 4
N = 8P4 = 8!/(8-4)!
N= 8!/4!
N = 1680
Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
Angles in a triangle add up to 180 degrees so
41+71=112
180-112=68
Angle of BAC=68 degrees
Answer:
if each side is 6 millimeters and its a cube what is 6x4
Step-by-step explanation:
Since

, and you have a corresponding term in the given Riemann sum of

, you know the integral is being taken over an interval of length 5, so you can omit the second choice.
Next,

corresponds to

with

. The fact that

alone tells you that the interval of integration starts at 3, and since we know the interval has length 5, that leaves the first choice as the correct answer.
