17) from least to greatest
1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, 1
Answer:
(3, -8)
Step-by-step explanation:
-3*3 - 3y = 15
-9 -3y = 15
3y = -24
y = -8
Answer:
(a) 
and 
(b) The sample variance is 
and the sample standard deviation is 
Step-by-step explanation:
(a)
The sum of these 17 sample observations is
and the sum of their squares is
(b)
The sample variance, denoted by 
, is given by
where 
Applying the above formula we get that
The sample standard deviation, denoted by <em>s</em>, is the (positive) square root of the variance:
Applying the above formula we get that
Answer:
It's true.
Explanation:
2(segment ST) = RT
divide both sides by two
ST = RT/2
You would have two equal halves of RT. One half equals RS. The other half equals ST.
Here's a rough picture of the line.
R _____________S_____________ T
S is in the middle of the line which makes it the midpoint.
It's true. S is the midpoint of RT.
The vertex will be a maximum because the equation is negative, meaning the parabola opens downwards and will have a maximum point but no minimum point as it will get infinitely smaller.
