EXPERIMENTAL probability is what was found in the experiment lands on five 4 out of 20 times 4/20 = 1/5
the EXPECTED probaility would be 1/6 * 20 = 20/6 = 3 1/3 times out of 20 rollls
Find inverse of f(x)
y = (x+5)/3 switch x's and y's then solve for y
x = (y+5)/3
y = 3x -5 this is f-1(x)
then g ( x ) = 1 / [(3x-5) +1 ]
and g(3 ) = 1 / [ (3*3 -5) + 1] = 1/5
Coulomb's Law
F = kc q1 q2 / (r^2)
9 = (9 x109) (.0005) (q2) / ( 102) N
q2 = ( 9* 102) / [(9x109)(.0005)] C Since it is an ATTRACTIVE force q2 will be positive (since q1 is negative) You can finish !
3 out of 11 are red First marble red : 3/11
now there are 10 marbles left of which 8 are blue Second marble blue : 8/10
3/11* 8/10 = 12/55
What is your question??
Need an image...or more info o/w the width can be any value !
If Alvin keeps 1/3 then the remainder that Alvin gives away is 2/3 of the total
Joyce gets 5/8 of the remainder......Sean gets 3/8 of the ramiander
2/3 * 3/8 = 6/24 = 1/4 of the total is what Sean gets
Zeroes at -2 and 3
a (x+2)(x-3) = 0
f(x) = a ( x*2 -x -6) When x = 5 f(x) = 10
10 = a ( 5^2 -5-6)
a = 5/7
f(x) = 5/7 (x^2-x-6)
Volume starts as 400 then it is compressed to 50 cm3
400/50 = 8 compression ratio is 8:1
TEN years ago : 4+3+1 = 8 TEN years ago (102-30) = 72 72/8 = 9
Randy was 3 * 9 = 27 ten years ago now he is 37 y/o
