To multiply B and A, the number of columns of B must matc the number of rows of A.
<h3>
When we can multiply two matrices?</h3>
When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.
Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).
To multiply BxA:
Then, a row on matrix B must have the same number of elements than a column in row A.
Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.

Answer:
Step-by-step explanation:
Angle E is one-half the measure of the difference between arc CG and arc DF. Mathematically, that looks like this:
and
44(2) = 160 - DF and
88 = 160 - DF and
-72 = -DF so
DF = 72 degrees, second choice down
Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30
x = 15
Your age is 15 and your sisters is 17

I will draw a rough figure, you can draw it neatly.
Probability =
Probability = No. of favourable outcomes/ Total no. of outcomes
Probability = No. of favourable outcomes/ Total no. of outcomesTotal number of outcomes = 4
So, here:
P(2) = 2/4 = 1/2
P(1) = 1/4
P(3) = 1/4
P(4) = 0
Here, the probability of getting 2 is ½.
Probability of getting 1 is ¼.
Probability of getting 3 is ¼.
Probability of getting 4 is 0.
