Answer:60
We may write the solution symbolically as LCM(12, 20) = 60. This says "the least common multiple of 12 and 20 is 60.
Step-by-step explanation:
4
The common factors of 12 and 20 are 1, 2 and 4. The greatest common factor of 12 and 20 is 4. To find the Greatest Common Factor (GCF) of two or more whole numbers, follow this procedure: Make a list of factors for each whole number.
Hope this helps you out ツ
Answer
(a)
(b)
Step-by-step explanation:
Remember that when you want to solve a problem like this, you express the equation as following
So, if you know the inverse of then
For this case
Now for this case the inverse of A would be
Then when you multiply with the vector solution
So from that information you can conclude that the solution to the system of equations is x = 500/7 y = 2400/7 and z = 2700/7
Answer:
196
Step-by-step explanation:
Formula of degree of freedom for simple regression = n-2
Formula of degree of freedom for multiple regression = n-k-1
We are given the case of multiple regression and there are three independent variables.
So, k = 3
n = 200
So, Degree of freedom for multiple regression =
=
=
So, Option A is true .
Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196
Try this explanation:
1. if to re-write the given function as:
then it is possible to define its range:
2)
answer: (0;1)
If we intersect the circle of radius 1 around (4,-4) and the circle of radius 1 around (4,-6) they'll intersect at the center of circle radius 1 that has both those points.
Here we don't really have to do any math. It's clear that the midpoint (4,-5) is 1 away from both (4,-4) and (4,-6) so that's our answer:
Answer: (4,-5)
