</h2>
First option is the correct option.
Step-by-step explanation:
Factor out X from the expression
Using , factor the expression
Write all numerators above the Least Common Denominators x ( x - 3 ) ( x + 3 )
Multiply the parentheses
When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression
Distribute -x through the parentheses
Using , simplify the product
Collect like terms
Subtract the numbers
Distribute x through the parentheses
Write 7x as a sum
Factor out X from the expression
Factor out 2 from the expression
Factor out x + 5 from the expression
Hope this helps...

Answer:
The degrees of freedom are given by:
The p value for this case would be given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes
Step-by-step explanation:
Information given
represent the sample size
represent the confidence level
represent the sample variance
represent the value that we want to verify
System of hypothesis
We want to test if the true deviation for this case is lesss than 5minutes, so the system of hypothesis would be:
Null Hypothesis:
Alternative hypothesis:
The statistic is given by:
And replacing we got:
The degrees of freedom are given by:
The p value for this case would be given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes
C: 15,938 + 427 is 4 times as large as (15,938 + 427) /4
Given:
Speed = 6 miles per second
If the Saturn revolves 6 miles in 1 second then the speed is:
So speed in minutes is 360 miles per min.
In 3 minutes traveling distance is:
