Therefore, slope of line DC = slope of line AC = -0.4.
Answer:
A)0.5
Step-by-step explanation:
We can see in the graph , that it is bell-shaped along x =2. A bell-shaped graph along one value is called symmetric graph and it represents a normal distribution.
Since, the give graph is symmetric around x=2, so the mean of the data is 2.
The point immediate left to the mean represents x-σ
so,
2 - σ = 1.5
So,
σ = 0.5
The sigma represents standard deviation.
Hence, Option A is correct ..
Answer:
option C. Defined, 3 x 3
Step-by-step explanation:
The order of matrix A is 3 x 2 i.e 3 rows and 2 columns
The order of matrix B is 2 x 3 i.e. 2 rows and 3 columns
Two matrices can be multiplied if and only if the number of columns of 1st matrix is equal to the number of rows of 2nd matrix. Since the number of columns in matrix A is equal to the number of rows in matrix B, the product AB is defined.
The product AB will have number of rows equal to the rows of 1st matrix i.e. matrix A and number of columns equal to the columns of 2nd matrix i.e. matrix B.
So the order of AB will be 3 x 3 .
Therefore, the correct answer is option C. Defined 3 x 3
-9/4, -2.1 , -26/13, -13/8 you can double check by inserting all these into a calculator so u can see in decimal form and basically the bigger the number that’s negative the less value it is (sorry that’s kind of a bad explanation but i hope this helps :) )
