I)
The Midpoint M of the line segment AB is found using the Midpoint formula:

ii)
the slope of the line through A and B is found by the slope formula:

iii)
the product of the slopes of 2 perpendicular lines is -1, so the slope of the line perpendicular to the line through A and B is -1/(-1)=1
iv)
the equation of the line with slope 1, which contains point M(3, 9) is found by the slope point form equation of a line:
y-9=1(x-3)
y-9=x-3
y=x+6
Answer: y=x+6
Answer:
The test statistic is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The The level of significance is 
The sample size is n = 18
The null hypothesis is 
The alternative hypothesis is 
The sample mean is 
The standard deviation is 
Generally the test statistics is mathematically represented as

substituting values


Answer:
to graph an inequality you need a variable. your question does not have a variable. please rewrite the question.
The answer is 76.99 but rounded would make it 77.00 which is C
