Answer:
A. Because the sample size is very large.
Step-by-step explanation:
The sample is quite large, so the t test is safe. With a sample size of at least 100, this test is going to be safe.
So the correct answer is:
A. Because the sample size is very large.
Answer:
C complex
Step-by-step explanation:
a+ bi
a is the real part and bi is the imaginary part
Together they make a complex number
It is 101,269 that is the answer for your quistion
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
The first triangle you do 1/2 of 9 x 18 then the second one is 1/2 of 9 x 9 and then you add the two.
