Answer:
x=28
Step-by-step explanation:
|28-x|=0
|28-28|=0
x=28
When two random variables X and Y are considered to be independent, it means that neither X's distribution nor Y's values have any bearing on the other.
<h3>What do you mean by independent random variable?</h3>
A random variable is a variable used in an experiment, such as the number of coin tosses or card draws. An independent random variable is a random variable in your experiment that doesn't affect the other random variables. In other words, it has no impact on the likelihood that another event will occur. For illustration, suppose you randomly selected 50 bags of sugar from various grocery stores in order to determine the average weight of a bag of sugar. The factors are independent since you wouldn't anticipate the weight of one bag having an impact on another. A dependent random variable, on the other hand, does have an impact on the probability of other random variables.

A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure.
Answer:
So on this case the best option for the answer would be:
between .01 and .025
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have 
groups and on each group from 
we have 
individuals on each group we can define the following formulas of variation:
And we have this property
The degrees of freedom for the numerator on this case is given by 
where k =4 represent the number of groups.
The degrees of freedom for the denominator on this case is given by 
.
And the total degrees of freedom would be 
We can find the 
And 
And the we can find the F statistic 
And with that we can find the p value. On this case the correct answer would be 3 for the numerator and 16 for the denominator.
So on this case the best option for the answer would be:
between .01 and .025
Since there are 60 seconds in a minute multiply 8 by 60
The rate is 480 feet per minute.
