After talking with you here are two different options I think you are trying to ask:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are talking about:
Answer: -62
Explanation:
PEMDAS tells us we need to do the exponent first:
-12³ = (-12)³ = -1728
<em>The parentheses are important so you cube the negative sign as well!</em>
3³ = 27
-1728 / 27 = -62
simplified is -62
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are talking about (-1)³
Answer: -
Explanation:
First, let us turn -1 and two thirds into a mixed number:
Ignoring the negative for now, we can 1 times 3 is 3. 3 plus 2 is 5. 5/3 is 5/3. Adding in the negative we get
To cube it we must do:
()(
)(
)
3 times 3 (9) times 3 is 27
5 times 5 (25) times 5 is 125
So we have 125/27
For the negative, we have three - - -
Two cancel each other out, and we are left with one (-) so our answer is negative
(-1)³ simplifed is -
Based on the information given, the true statement true about their gas-price data is A. Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
<h3>Solution to the gas-price data.</h3>It should be noted that a standard deviation simply measures how dispersed the data will be in relation to the mean.
From the complete question, the mean of Raquel's data is given as 3.42 while the standard deviation is given as 0.07. On the other hand, the mean of Van's data is given as 3.78 while the standard deviation is given as 0.23.
Therefore, it can be deduced that Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
