Answer:
Correct V100 is right
Step-by-step explanation:
The area of the rectangle is 
units.
Step-by-step explanation:
Step 1:
The area of a rectangle is obtained by multiplying the length with the width of the rectangle.
Considering this a whole rectangle, the length of the rectangle is 5 units and the width is the sum of 
, 
, and -6.
So the length of the rectangle = 5 units and
the width of the rectangle 
units.
The area of a rectangle = (length)(width).
Step 2:
By substituting the known values, we get
The area of the rectangle 
So the area of the rectangle is units.
Answer:
see below
Step-by-step explanation:
prove: sin²x cos²y - cos²x sin²y ≡ sin²x - sin²y
we notice that the Right side only has sin² functions, hence we can start by trying to remove the cos² functions from the Left side.
Recall the identity: sin²α + cos²α = 1 , can be rearranged to give us:
cos²α = 1 - sin²a.
If we apply this to the left side of our equation, then
cos²y = 1-sin²y, and cos²x = 1-sin²x
Substituting these into the left side of the equation:
sin²x cos²y - cos²x sin²y
= sin²x (1-sin²y) - (1-sin²x ) sin²y
= sin²x - (sin²x sin²y) - sin²y + (sin²x sin²y)
= sin²x - sin²y
= Right Side of equation (Proven!)
The values cannot be labeled as dependent or independent without a givin equation
The odds against selecting a red marble is =2/11
<h3>Calculation of probability</h3>
The number of marbles which were red = 9
The number of marbles which were blue = 2
The total amount of marbles in the Box = 11
When one marble is picked at random from the box, the odds against selecting a red marble can be gotten through the blue marble.
That is, the number of blue marble/ total marble
= 2/11
