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
Let

represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:

. Now, we know that the the cost of materials is 30 dollars and the cost of labor is 0.1 dollars, so the total coast to produce

hard drives will be:

.
Now the only thing left is add t<span>he cost of equipment to complete our function:
</span>

We can conclude that the equation that could represent the cost function for making x hard drives is <span>
f(x)=30.1x+10,000</span>
