Answer:
The slope of FG is -1
Step-by-step explanation:
Given
Square EFGH
EF: 
Required
Determine the slope of FG
First, we calculate the slope of EF
Make y the subject
The general equation has the form: 
Where
Compare to
<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>
<em />
The relationship between perpendicular lines is:
Where
-- Slope of EF
and
m2 = slope of FG
Substitute 1 for m1 in
<em>Hence, the slope of FG is -1</em>
6 cups.
2/5 of the mixture would be lemon juice, and 2/5ths of 15 is 6
The degree of a line is 180, so..
Put it into an equation form: 5x + 75 = 180
1st combine like terms by subtracting 75 from 180
now your equation looks like this: 5x = 105
next you divide 5 from both sides, 105 divided by 5 is 21, so your answer is: x=21
I hope this helps!♥
Answer:
C. becomes narrower
Step-by-step explanation:
If the confidence level is reduced from 95% to 90%, then, the confidence interval for u becomes narrower, i.e., we are less sure that the true value of u is contained inside the new interval. With a 95% confidence interval there is a probability of 0.95 that the parameter u is inside the interval and with a 90% confidence interval there is a probability of 0.90 that the parameter u is inside the interval.
