Parallel because they have the same slope
Answer:
x=-1
Step-by-step explanation:
The axis of symmetry is along the vertex
The vertex is at (-1,-2)
The x coordinate is -1
x=-1
Answer:
The test statistic would be given by:
(1)
And replacing we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
t would represent the statistic
System of hypothesis
We want to test if the true mean is lower than 25, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The test statistic would be given by:
(1)
And replacing we got:
Answer:
- 3r + 18
Step-by-step explanation:
7r - 8r - 2r + 13 + 5 = 7r - 10r + 18
I think its 3,600, because you usually have to multiply the numbers.
