Answer:
n= -3
Step-by-step explanation:
-3n+(-4)=5

Answer:
D
Step-by-step explanation:
What we need to do is find the operation between f(x) and g(x) that results in h(x).
Notice how there's a pattern, the value of h(x) is always equal to the values of g(x) and f(x) added together.
This can be represented by the expression (g+f)(x), the expression in D.
Answer:
2.897
Step-by-step explanation:
Let us find the mean and variance for the sample first.
105 104 110 112
114 106 108 109
Mean = sum/8 = 108.5
Variance = 12
Std dev = sq rt of variance = 3.464
Std error = std dev/ sq rt n
since n =8, we get std error = 1.225
Since sample size is small, df =8-1 =7
For 95% confidence intervals, t critical value for two tailed=2.365
Margin of error = std error x t critical = 1.225(2.365)
=2.897
Here is what I got
