Answer:

Step-by-step explanation:
The solution is in the image
The best approach to this is to use the formular
Standard error = standard deviation / sqrt( sample size)
standard deviation = 0.75 hours
sample size = 35
Hence, Standard error = 0.75 /sqrt(35) = 0.126 = 0.13
Answer:
The other term is<u> (x-3)</u>
Step-by-step explanation:
The quadratic function is:

Factoring this function we will have:

Therefore, the other term is<u> (x-3).</u>
I hope it helps you!
I would suggest factoring using the grouping method. The answer I got was (2n-1)(n+2)
