(21 + 34 + x + 25 + 37 + 22) / 6 = 30
(139 + x) / 6 = 30 .....multiply both sides by 6
139 + x = 30 * 6
139 + x = 180
x = 180 - 139
x = 41......so during week 3, she rode her bike 41 miles

Which measure of central tendency is least appropriate for describing the given data set?. 6, 6, 6, 7, 8, 8, 29. . a. mode. b. m
maksim [4K]
Mode is which number appears the most. Mean is adding up all the numbers and dividing by the amount of numbers. Median is the middle number of the ordered numbers from least to greatest. Look at the set. they are in order so median is off. Numbers appear more than once so mode is off. However, mean is not there. We don't have an average. (adding up the numbers and dividing by amount.) So the answer should be mean. 

good luck!

hjlf
Given that o<span>ne Friday night, Roman and Malou are busy studying for their Logic exam. Meanwhile, Hadji just tweeted a picture of himself eating crispy pata and sisig. Jeff is sound asleep in his dorm room.

Part A:

The truth value of </span>"Either Roman has a date with Malou, or Jeff is sleeping or Hadji is eating." is obtained as follows:

From the scenario, the truth value of the individual statements are as follows:

<span>Roman has a date with Malou is True
</span>
<span>Jeff is sleeping is True
</span>
<span>Hadji is eating is True

Thus, the truth value of "True" or "True" or "True" is True.

Therefore, the truth value of "</span><span>Either Roman has a date with Malou, or Jeff is sleeping or Hadji is eating." is True.



Part B:

</span>The truth value of "Either Jeff is sleeping or Hadji is not eating" is obtained as follows:

From the scenario, the truth value of the individual statements are as follows:

<span>Jeff is sleeping is True
</span>
<span>Hadji is not eating is False

Thus, the truth value of "True" or "False" is True.</span>

Therefore, the truth value of "Either Jeff is sleeping or Hadji is not eating" is True.



Part C:

The truth value of "Roman and Malou are on a date and Jeff is sleeping, or Hadji is not eating." is obtained as follows:

From the scenario, the truth value of the individual statements are as follows:

Roman and Malou are on a date is True

<span>Jeff is sleeping is True
</span>
<span>Hadji is not eating is False

The truth value of "True" and "True" is True.
The truth value of "True" or "False" is True.

Thus, the truth value of ("True" and "True") or "False" is True.
</span>
Therefore, the truth value of "Roman and Malou are on a date and Jeff is sleeping, or Hadji is not eating." is True.
