According to the rational root theorem, the numbers below are some of the potential roots of f(x) = 10x3 + 29x2 – 66x + 27. select all that are actual roots. a) -9/2 b)-9/10 c) 3/5 d) 1 e) 3

answer : A , C , D

WE plug in each root in f(x)  and check whether we get value =0

When f(a) =0  then  'a' is the actual root

Lets start with -9/2, plug in -9/2 for x

Hence -9/2 is one of the actual root

now plug in -9/10 for x

Hence -9/10 is not an actual root

now plug in 3/5  for x

So 3/5 is one of the actual root

Now plug in 1 for x

So 1 is one of the actual root

Now plug in 3 for x

So 3 is not the actual root

Answer is -9/2  , 3/5  and 1

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
