Answer:
-3 and 3/2
Step-by-step explanation:
6x^3 - 2x^2 + x + 3
possible roots are p/q where p = factors of 3 and q are factors of 6
So from the 4 choices possible roots are -3 and 3/2

Answer:
The mean of X is 2
Step-by-step explanation:
Given the data in the question;
set of 10 cards consist of 5 red card and 5 blacks
cards are chosen, replaced and shuffled four times;
number of independent trials n = 4
now, since its is replaced, the probability of getting a red card in each trial will be;
p = 5/10 = 0.5
let X rep the number of red cards observed in the four trials.
the random variable follows binomial distribution where
n = 4 and p = 0.5
so
E(X) = ∑xP( X = x )
E(X) = np
we substitute
E(X) = 4 × 0.5
E(X) = 2
Therefore, The mean of X is 2
I got 6.49204 but you will need to round so D 6.5
I added all of the numbers up
