Answer:
e= -5.41
Step-by-step explanation:
Hello!
In linear regression, a residual value is a distance between the observed values and the regression line.
The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).
e= Y - ^Y
e= 15.92 - 21.33 = -5.41
I hope it helps!
Answer : The correct option is, (B) 1500 cubic yards.
Step-by-step explanation :
Formula used to calculate the volume of square pyramid is:
where,
V = volume of pyramid
a = base edge of pyramid
h = height of pyramid
Given:
Base edge of pyramid = 15 yards
Height of pyramid = 20 yards
Now putting all the given values in the above formula, we get:
Therefore, the volume of pyramid is 1500 cubic yards.
Answer:
A) The parallelogram is a rhombus
Step-by-step explanation:
A rhombus is an equally 4-sided figure with two acute angles and two obtuse angles opposite of each other.
Answer:
AB represents a line segment because the points limit the line from continuing on either end.
If you include the ray on the left side, then it would be considered a ray.
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
