Answer:

Step-by-step explanation:

The answer is graph D because in the word problem it says, "more than three copies". We can also see that we need to find how many copies are made in 4 hours. Since it says more than and we do not have another number, we will multiply 3 and 4.

3 x 4 = 12

This is a line graph. An enclosed circle on a number would mean that this line includes the number. This circle is open, not enclosed so 12 is not a part of the line for graph D.

Since it says more than, this open circle makes sense, because it was more than 3 books, but not 4 books. This means it can range anywhere after 3. (examples: 3.1 books, 3.5 books, 3.8 books) this means it can also range anywhere after twelve.

This combined shows us that graph D is the answer.

Identity the composite number represented by the prime factorization below

Korolek [52]

Answer:look below

Step-by-step explanation: The prime factorization of number is the break down into factors which are prime numbers (numbers without factors except 1 and itself). The factors 22 and 32 are composite numbers since they have more than 1 and itself as factors. They are not prime.

However, the factorization of 22 * 32 * 5 will equal a number. 22*32*5 = 3, 520. But it does not match the solutions given.

If 90 percent of automobiles in Orange County have both headlights working, what is the probability that in a sample of eight au

Marta_Voda [28]

Answer:

$P(X \geq 7) = P(X=7) +P(X=8)$

And we can find the individual probabilities using the probability mass function

$P(X=7)=(8C7)(0.9)^7 (1-0.9)^{8-7}=0.3826$

$P(X=8)=(8C8)(0.9)^8 (1-0.9)^{8-8}=0.4305$

And replacing we got:

$P(X \geq 7) = P(X=7) +P(X=8)=0.3826 +0.4305=0.8131$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest "number of automobiles with both headligths working", on this case we now that:

$X \sim Binom(n=8, p=0.9)$
