Answer: Dim Col A = 4.
Step-by-step explanation:
Since we have given that
Matrix A has 5 rows and 8 columns.
And Nul A = 4
It implies that the rank of A would be
Number of columns - Nul A = 8 - 4 =4
So, rank A = 4
so, it has dim Col A = 4 also.
But the four vector basis lie in R⁵.
Hence, Dim Col A = 4.
Answer:
$276
Step-by-step explanation:
Create a proportion where x is the cost to refinish the larger wood floor:
= ![\frac{x}{207}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B207%7D)
Cross multiply and solve for x:
3x = 828
x = 276
So, to refinish the larger wood floor, it would cost $276
Answer:
1/16
Step-by-step explanation:
Demont made one fourth (
) pound of rock candy
He separates the candy into four sacks equally.
This is done by dividing the total fraction of candy of a pound of candy made by the number of sacks
The fraction of a pound of candy that will be in each sack therefore is:
![\frac{1}{4}\div 4= \frac{1}{4}X\frac{1}{4}=\frac{1}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%5Cdiv%20%204%3D%20%5Cfrac%7B1%7D%7B4%7DX%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B1%7D%7B16%7D)
Therefore, One-Sixteenth of a pound of candy will be in each of the sack.
If there are a total of 12 players and 4 are trumpet players than there are 8 flute players.
Twice are many trumpet players is 8 because you just do
![4 \times 2 = 8](https://tex.z-dn.net/?f=4%20%5Ctimes%202%20%3D%208)
so yes, there are twice as many flute players.
