Amani computed in a two-way table the relative frequencies of sales of homes listed with two different real estate companies.
Advocard [28]

The answer the third option.

When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.

In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.

1) Alice is a truck driver who drives the same route every day for 5 days. On the
s2008m [1.1K]

Answer:

Alice drives 168.26 miles daily and 841.3 miles per 5 days on her regular route when there is no detour.

Step-by-step explanation:

First, we need to <em>divide</em> 927.8 miles by 5.

927.8 ÷ 5 = 185.56 is her daily mileage, including the detour.

Since her detour <em>added </em>17.3 miles to her <em>daily mileage</em>, we need to <em>subtract </em>this from her current daily mileage.

185.56 - 17.3 = 168.26 is her daily mileage when there is no detour.

Now, in order to find her mileage for 5 days, we need to <em>multiply</em> this number by 5.

168.26 x 5 = 841.3

Therefore, Alice drives 168.26 miles daily and 841.3 miles per 5 days on her regular route when there is no detour.

Oduvanchick [21]

Answer:

Step-by-step explanation:

Using the mean concept, it is found that the average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.

-----------------

The mean of a data-set is given by the sum of all observations divided by the number of observations.

Adrian looked the scores every 10 minutes in 2 hours, thus 12 times, as .

4 times ahead by 3 points, thus  

4 times behind by 4 points, thus  

At the other moments, the game was tied, thus the observation is 0.

Thus, the mean is of:

The average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.

Jorge has saved $15.50. Janet saved 1/5 of the amount that Jorge saved. Rob saved 12 times as much of Janet. What is the total s
KiRa [710]

Answer:

$55.80

Step-by-step explanation:

First, find how much Janet saved by finding 1/5 of 15.50:

15.50/5

= 3.1

Find how much Rob saved by multiplying 3.1 by 12:

3.1(12)

= 37.2

Then, find the total saved amount by adding them all together:

15.50 + 3.1 + 37.2

= 55.8

So, they saved $55.80 in total
