Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
Answer: 8
Step-by-step explanation:
The degree of freedom for t-distribution of testing the differnce between the two population mean is given by :-
, where 
= Size of first sample.
= Size of second sample.
As per given ,
Veterinarian selects five horses that are known to have enteroliths and compares the number of flakes of alfalfa they have eaten over a month with the number of flakes eaten by five horses free of enteroliths.
i.e. 
and 
Now , If she calculates a two-sample confidence interval by hand for the difference in the mean number of flakes fed to horses with and without enteroliths the degrees of freedom she should use are
Hence, the correct answer is 8.
Answer:
<h2>x = -1</h2>
Step-by-step explanation:
According to the given table, we see that for <em>x = -1</em>, the function is not defined, that means that the rational function has a restriction there, and such restriction is shown as an asymptote in the graph of the function.
So, basically, we could say that the given rational function has one asymptote and it's at x = -1, which is a vertical asymptote, because all forms like x = k, are vertical lines, that is, they are parallel to the vertical axis.
Therefore, the right answer is the third choice.

Answer:
Object 1 is the heaviest object.
Step-by-step explanation:
The first column of the table tells you ...
Object 1 is heavier than the 10 kg weight
The second column of the table tells you ...
Object 2 weighs 10 kg
The third column of the table tells you ...
Object 3 is lighter than the 10 kg weight
Then the relative weights are ...
Object 1 > Object 2 > Object 3
That is, Object 1 is the heaviest object.
Ruby wants to <u>start</u> her own <u>business</u> taking photographs. She has to <u>purchase</u>
- photo printer for $251.99;
- lights for $150.00;
- photo paper for $30.98.
In total, she will use
$251.99 + $150.00 + $30.98 = $432.97.
If she has $840.32 in savings, then
$840.32 - $432.97 = $407.35 will remain.
Answer: she will use $432.97 - correct answer A
