Answer:
D
Step-by-step explanation:
If there is a 2x2 matrix as ![\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5C%5C%5Cend%7Barray%7D%5Cright%5D)
The determinant is given by ![\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bad-bc%7D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dd%26-b%5C%5C-c%26a%5C%5C%5Cend%7Barray%7D%5Cright%5D)
<em>Now, if we calculate the value of "ad - bc", we see that:</em>
We can't calculate the inverse, the inverse doesn't exist. The answer is D.
The pythagorean theorem equation is a^2 (a squared) + b^2 (b squared) = c^2 (c squared)
so a^2+b^2=c^2
12-4=8 which means 12-8=4 which means now you have the difference of 4 and 8+4=12 which means now you have the sum of 12
It is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.
As given in the question,
Number of cards are unknown.
Number of red cards are unknown in the starting of experiment.
Number of times process done =10
For binomial random variable number of red cards should be known.
Therefore, it is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.

The slope is three because the x goes up 1 and y goes up 3 so it’s 3/1 which makes the slope 3
