I’m not sure if you were using exponents, but if you were, this is it simplified.
Formula of determinant is ad - bc
= 2 x 9 - 4 x 3
= 18 - 12
= 6
So the required determinant of given matrix is 6
Answer:
9.87%
Step-by-step explanation:
We know that the clock must ring 4 times, but there must be 7 rings. The only way for this to happen is that of the 4 times, 3 that the bell rings 2 times and 1 that rings only once. So it would be:
2 + 2 + 2 + 1 = 7
So the final probability would be the multiplication of these events, therefore:
(2/3) * (2/3) * (2/3) * (1/3) = 0.0987
In other words, the probability is 9.87%
y=f(x³y-3),(y-2)
Step-by-step explanation:
(x,y)>(x-2+y3)
(x,y)(x+3,y-3) or (x+y)
hope it's help
Step 1) 2x-5y+x+y=2x+x-5y+y
step 2) 2x+x-5y+y=3x-4y
by putting together like terms you get the answer 3x-4y so your answer should be A
