The probability a randomly selected household owns corporate stock is 0.54. The probability a randomly selected household has no

34kurt

Answer:

30% probability a randomly selected household has no Internet access given the household owns corporate stock

Step-by-step explanation:

I am going to say that we have two events.

Event A: Owning corporate stock. So P(A) = 0.54.

Event B: Having no internet access. So P(B) = 0.3.

Since they are independent events, we can apply the conditional probability formula, which is:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probabilitty of event B happening given that A happened. We want to find this.

$P(A \cap B)$ is the probability of both events happening.

Since they are independent

$P(A \cap B) = P(A)P(B) = 0.54*0.3$

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.54*0.3}{0.54} = 0.3$

30% probability a randomly selected household has no Internet access given the household owns corporate stock

Helloooo can someone help meeeeeeeee

Liono4ka [1.6K]

Answer:

Option B, $(48x^{8}y^{5})$

Step-by-step explanation:

<u>Step 1: Simplify the exponent</u>

$(12x^{2}y^{3})(2x^{3}y)^{2}$

$(12x^{2}y^{3})(2^{2}x^{3*2}y^{1*2})$

$(12x^{2}y^{3})(4x^{6}y^{2})$

<u>Step 2: Simply the expression</u>

$(12x^{2}y^{3}*4x^{6}y^{2})$

$(48x^{2+6}y^{3+2})$

$(48x^{8}y^{5})$

Answer: Option B, $(48x^{8}y^{5})$

1. A study of college freshmen found that students who watched TV for more than one hour each night gained 15 pounds in the firs

umka21 [38]

Answer:

C. They most likely used an observational study asking students to keep track of their TV habits and weight.

A. This is an experiment because a treatment was applied to a group.

Step-by-step explanation:

According to our question:

1. The study concluded that there is a relation between watching TV and the weight gain in college freshmen.

Now, this is possible when a group of college students were asked to participate to watch TV for more than 1 hour for a specific amount of time and have a record of their weights.

So, the study is an observational study where the habits and weights of college students were observed.

Hence, option C is correct.

2. The students were divided onto two groups where one group used the computer program and the other did not to check the improvement in the reading levels.

This means that the students were given a procedure to follow during the study in order to see the results..

So, the study is an experiment where a treatment is applied to the group of students.

Hence, option A is correct.
