Answer:
units.
Step-by-step explanation:
The given functions are:
and
The function has y-intercept ,
.
The function has y-intercept,
If we shift the graph of g(x) up to obtain f(x), then the y-intercept must move from to
.
This means that the graph will move up by;
units.
Answer:
We just add numerators and rewrite denominator.
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
Step-by-step explanation:
You mean unlike denominators and like denominators.
Adding like dominators: We just add numerators and rewrite denominator :
Example :
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
For example :
LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :
Answer: 1.303639
Step-by-step explanation:
The t-score for a level of confidence is given by :_
, where df is the degree of freedom and
is the significance level.
Given : Level of significance :
Then , significance level :
Sample size :
Then , the degree of freedom for t-distribution:
Using the normal t-distribution table, we have
Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639
