Step-by-step explanation: then u round up to 3 singnificant figures
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.
1/2x - 3 = 3/2x + 4
-4 - 3 = 3/2x - 1/2x
-7 = x <===
Answer:
Bar Chart
Step-by-step explanation:
The Bar graph is has immense capability in the aspect of data visualization. It is capable of grouping data into different categories, such as in the scenario above, where fishes are grouped based on species. These groups are then represented as vertical bars displaying the number of these species of fish. With this we can make comparison and inferences regarding the maximum, minimum and other summary statistics about the distribution.
