Dude what’s the difference between a blind experiment and a double blind experiment
EITHER WAY UR BLIND LOL
Answer:
b) -9.25
Step-by-step explanation:
-1/4 = -0.25
-9 + -0.25 = -9.25
-10, -9.75, -9.5, -9.25, -9, -8.75, -8.5, -8.25, -8, -7.75, -7.5, -7.25, -7
Hope this helps!
I did a quick search and the web said there are 12 categories! So none of the choices...
"Excel groups functions into 12 categories: Compatibility, Cube, Database, Date and Time, Engineering,Financial, Information, Logical, Lookup & Reference, Math & Trigonometry, Statistical and Text."
There's one other category called "Web functions", mentioned in Microsoft's website.
So the answer is 13.
Answer:
The solution to the system is 
,
and 
Step-by-step explanation:
Cramer's rule defines the solution of a system of equations in the following way:
, 
and 
where 
, 
and 
are the determinants formed by replacing the x,y and z-column values with the answer-column values respectively. 
is the determinant of the system. Let's see how this rule applies to this system.
The system can be written in matrix form like:
![\left[\begin{array}{ccc}5&-3&1\\0&2&-3\\7&10&0\end{array}\right]\times \left[\begin{array}{c}x&y&z\end{array}\right] = \left[\begin{array}{c}6&11&-13\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%26-3%261%5C%5C0%262%26-3%5C%5C7%2610%260%5Cend%7Barray%7D%5Cright%5D%5Ctimes%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%26y%26z%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D6%2611%26-13%5Cend%7Barray%7D%5Cright%5D)
Then each of the previous determinants are given by:
Notice how the x-column has been substituted with the answer-column one.
Notice how the y-column has been substituted with the answer-column one.
Then, substituting the values:
The coordinates of Q are (-1,6)
