Answer:
1,5 is your answer
Y=5 and X=1
Insert it in the equation
5=3(1)+2
5=3+2
5=5
Hence proved!
Answer:
Step-by-step explanation:
The line will not pass through the origin.
Instead, the graph will cross the y-axis at a point known as the y-intercept.
Answer:

Step-by-step explanation:
The equation of the given line:

This equation is in the form
. Therefore, 1/3 is the slope.
To find a perpendicular line, take the opposite reciprocal of the slope (-1/old slope). Therefore, the slope of the perpendicular line is -3.
The equation of the perpendicular line: 
Answer:
So on this case the 95% confidence interval would be given by (155.301;159.299)
And the best option would be:
B. (155.3, 159,3)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n=234 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The Confidence level is is 0.95 or 95%, the significance is
and
, the critical value for this case would be
And replacing we got:
So on this case the 95% confidence interval would be given by (155.301;159.299)
And the best option would be:
B. (155.3, 159,3)
