Answer:

$12.79

Step-by-step explanation:

If each minute is $0.99, and Tiffany was there 7 minutes, we can multiply the two to get part of the cost.

$0.99 * 7 = $6.93

Now we add on the $5.86 as the flat rate.

$6.93 + $5.86 = $12.79

1.  What is the most important thing that must be true about a sample so that you can make a valid inference about the populatio
MissTica
<span>1.) The most important thing that must be true about a sample so that you can make a valid inference about the population is that the sample must not be biased.

2.) </span>I<span>t is important to take a random sample of the population you want to study because the population may be too large that it might be impossible or too expensive to conduct a survey on a population.

3.) </span><span>An outlier is an observation point that is distant from other observations. It can be too small or too big compared to other observations.</span>

The measure of center that is more affected by outliers in the data is the mean, because since the mean is obtained by the sum of the data divided by the number of the data set. Any 'too big' number or 'too small' number will affect the sum of the data set.

4.) Given that <span>Sam conducted a survey to find out the favorite weekend activity of the students his middle school. He asked 20 of his classmates. He found out that the favorite weekend activity of his middle school is playing video games because 75% of the students he surveyed liked to play video games.

</span><span>Sam’s sample may not be valid because he drew a sample only from his class to make an inference about the entire middle school students.

</span>For <span>Sam to improve his survey to be more representative of his school he must draw a random sample from all the classes that make up the middle school.</span>

15(2-x)=13(3-x) pls help
schepotkina [342]

Answer:

-4.5

Step-by-step explanation:

15(2-x)=13(3-x)

Expand parentheses:

30-15x=39-13x

Add 15x to both sides:

30=2x+39

Subtract 39 from both sides:

2x=-9

Divide both sides by 2:

x=-4.5

Hope this helps!
