Answer:
-3t - 33
Step-by-step explanation:
Distribute -3 to all terms within the other parenthesis:
(-3)(t + 11) = (-3)(t) + (-3)(11)
Simplify by multiplying:
(-3)(t) + (-3)(11)
-3t + (-33)
-3t - 33 is your answer.

The correct statement that can be made about the means is a. There is not enough evidence to suggest that the means are different.
<h3>What is true about the means?</h3><h3 />
Given that α = 0.01, we can use an ANOVA analysis to determine the p-value of the means.
When we run the means through an ANOVA software, the p-value can be found to be 0.1142.
This figure is greater than α = 0.01.
This means that we do not have the evidence to reject the null hypothesis that the means are different.
Options for this question:
- a. There is not enough evidence to suggest that the means are different.
- b. The mean age of middle school teachers is different from the mean age of high school teachers.
- c. The mean age of middle school teachers is different from the mean age of college teachers.
- d. The mean age of high school teachers is different from the mean age of college teachers.

The results of the 100 rolls with the number cube are such that the probability of rolling a 2 is<u> 32%.</u>
<h3>What is the probability of rolling a 2?</h3>
This refers to the chances that the number cube rolls a 2 when thrown.
This can be found by the formula:
= Number of times 2 was rolled / Total number of times number cube was rolled
Solving gives:
= 32 / 100
= 32%

A small outlier could affect the whole data set because it could reduce the mean, or make the average of the whole data set smaller.
An example would be the data set could be 1, 8, 9, 10
To find the mean you would add everything together then divide it by the number of numbers you just added together. The mean of this set would be 28/4 which equals 7. Now, if the outlier were -8 instead of 1, then the mean would be much different.
~Hope this helped!~
