Answer:

198

Step-by-step explanation:

rectangular side (9,3)

9x3=27

27x2= 54 (because there's rectangular sides)

Square end(6,3)

6x3=18

18x2=36(two square sides)

top&bottom sides

6x9=54

54xsquared2=108(two sides)

add all together

54+36+108=198cm(squared)

Let A and B are n x n matrices from which A is invertible. Suppose AB is singular. What conclusion can be made about the inverti
Montano1993 [528]

Answer: Matrix B is non- invertible.

Step-by-step explanation:

A matrix is said to be be singular is its determinant is zero,

We know that if a matrix is singular then it is not invertible.    (1)

Or if a matrix is invertible then it should be non-singular matrix.      (2)

Given :  A and B are n x n matrices from which A is invertible.

Then A must be non-singular matrix.                            ( from 2 )

If AB is singular.

Then either A is singular or B is singular but A is a non-singular matrix.

Then , matrix B should be a singular matrix.                   ( from 2 )

So Matrix B is non- invertible.                                     ( from 1 )

Why is sample size important in experimental design? A. Larger sample sizes increase the likelihood that the sample is a good re
nlexa [21]

Answer: A

Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below

Margin of error = critical value × σ/√n.

Where n is the sample size.

As we can see that the critical value is a constant and the population standard deviation.

Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.

If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.

What is the slope of the line that passes through (-2,-3) and (1,1)
kramer
Slope:
m =  \frac{y _{2} - y _{1}}{x_{2} - x _{1}}

Slope is rise over run. It is a ratio of the amount of the y-axis over the amount of x-axis. So, now assign the first group of numbers, (-2,-3) as 1; then the second group, (1,1) as 2. Like this:
first \: group(x _{1} ,y _{1}) \\ second \: group(x_{2},y_{2})
Notice the subscripted numbers designate the group number. Next, plug in the numbers and do the math.
\frac{1 - ( - 3)}{1 - ( - 2)}  =  \frac{1 + 3}{1 + 2}  =  \frac{4}{3}
So, the slope, m, is equal to four thirds.

m = 4/3
