Answer:
3
Step-by-step explanation:
We have given , and SP =30
We have to find the slope for regression on Y from X
The slope on Y from X is given by
As we have given the value of SP =30 and value of
So slope for regression will be
Answer:
Table A
Step-by-step explanation:
y = 3x^2 +2x -8
The quadratic is in the form
y = a x^2 +bx+c
a = 3 b = 2 c = -8
Since a > 0 it opens up
The y intercept is c so the y intercept is -8
Answer:
Step-by-step explanation:
we know that
The given figure is a triangular pyramid
The volume of the triangular pyramid is equal to
where
B is the area of the triangular base
h is the height of the pyramid
Find the area of the base
The base is an equilateral triangle
Applying the law of sines to determine the area
Remember that
substitute
Find the volume
we have
substitute
Answer: 2 fl oz
Step-by-step explanation:
Division with remainders
128/6=21.33333..
128-126=2
2 fl oz was left in the jug
If r=13cm, the d is double that so it is 26cm.
