Answer:
3c + 14d
Step-by-step explanation:
Hello There!
We can simplify this expression by combining like terms
Now what are like terms?
They are terms that have the same variable ex. 4a and 2a are like terms as they have the same variable (a)
Now lets look back at the expression and see if there are any like terms
which there are (4c and -c) and (6d and 8d)
so lets combine them
4c - c =3c
6d + 8d = 14d
so the simplified version would be 3c + 14d
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
