It seems there are always three pairs: SSS, side side side; SAS, side angle side; ASA, angle side angle.

For a right triangle (HL, LL) it seems there are only two items needed, but that's because we already know one angle (it's right).

Once we have congruent triangles, all the corresponding parts are congruent.  That's three sides and and three vertices, so I'd answer six.  Of course almost everything about the triangles is the same, the area, the perimeter, etc.

Calvin encoded a secret phrase using matrix multiplication. Using A = 1, B = 2, C = 3, and so on, he multiplied the clear text c
Vlad1618 [11]
Our matrix C is the encoder.  Let X be our secret message and let B be our encoded message.  Therefore the relationship between the 3 can be represented as:

CX = B

So we want to solve for X (our secret message). So using matrix algebra:

X = C^-1*B
where C^-1 is the inverse of C.

C^-1 = | 3 -2 |
           |4 -3 |

So we take C^-1 and multiply it by matrix B to get X.  Matrix B is already given to us.  So just multiply those two.  I used a calculator to get:

X = | 20 8 5 3 15 12 15 |
      | 18 9 19 2 12 21 5 |

And since A = 1, B = 2, C = 3, etc....

We decode our message and it says:

X = | T H E C O L O |
      | R I S B L U E |

So the answer is: The color is blue (D)

sampling distribution is statistical representation of statistics of each sample.  So for a class size of 30,

A. number of samples have to be very large and defined in sampling distribtuion so this option is nullified

B. sample collection in sampling distribution is done without replacement of individuals so this option is nullified

C. this explanation doesn't match with the definition so this option is nullified

D. It is the correct option
