Answer:
Step-by-step explanation:
20 cupcakes will cost $49.60. You divide 44.64 by 18 and get 2.48. Multiply 2.48 by two getting 4.96. Then you add 44.64 and 4.96 together and get your answer.
Answer:
63%
Step-by-step explanation:
This is a problem of conditional probability.
The two events that are given are:
- Car stuck in the snow - Let it be event S. P(S) = 70% = 0.70
- Require a tow truck - Let it be event T.
We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)
We are also given the conditional probability, which is P(T | S) = 90% = 0.90
Using the given formula for our case we can modify the formula as:


Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out
Answer:
C
Step-by-step explanation:
The inverse of a matrix is the transpose of the cofactor matrix, divided by the determinant. The determinant is (4)(3) -(1)(-5) = 17, eliminating choice B.
In a 2×2 matrix, the transpose of the cofactor matrix swaps the diagonal elements, and negates the off-diagonal elements. That is, the transpose of the cofactor matrix will look like the matrix of B. When that is divided by 17, you get the matrix of answer choice C.
