Mathematics
1 answer:
Semenov [28]3 years ago

Answer:

Dan is correct

Step-by-step explanation:

First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

Using this distribution, find the probability
kaheart [24]

Answer:

P = 0.3

Step-by-step explanation:

Here, we are to use the probability distribution in the table to calculate the probability that a children has 4 or more shoes in his or her closet

When we say 4 or more, what we mean by this is that the teenager has 4 shoes or 5 shoes

In probability expressions, when we use the term ‘or’ we are simply talking about adding the terms involved

So what we can do here is to add the probability that the teenager has 4 shoes to the probability that the teenager has five shoes

From the table that would be; 0.1 + 0.2 = 0.3

Don’t really understand it someone help
stich3 [128]

Answer:

<em>n = 8 or n = −2</em> <em>is the correction solution.</em>

Step-by-step explanation:

As the absolute value equation is given:                                      

                                            | n−3 | = 5

We know either n − 3 = 5 or n − 3 = −5

                                               n − 3 = 5            (First Possibility)

                                          n − 3 + 3 = 5 + 3

                                                       n = 8

                                                n − 3 = -5            (Second Possibility)

                                                      n = -5 + 3

                                                      n = -2

                  <em> So, n = 8 or n = −2</em> <em>is the correction solution.</em>
