Answer:
D
Step-by-step explanation:
The augmented matrix for the system of three equaitons is
Multiply the first row by 5, the second row by -3 and add these two rows:
Subtract the third row from the second:
Divide the third row by 6:
Now multiply the third equation by 26 and add it to the second row:
You get the system of three equations:
From the third equation
Substitute z=2 into the second equation:
Now substitute z=2 and y=5 into the first equation:
The solution is (1,5,2)
X=4 & y=3

Step-by-step explanation:
We search for red balls (neither yellow or black). There are 6 red balls among all 18 balls. Selecting one ball, there is a chance 6/18 that we pull out a red one. 6/18 is the same as 1/3.
The chance or chance that the lawn mower will hit a chunk of glass that is already cracked is calculated with the aid of dividing the variety of glasses that are cracked by way of the full quantity of glasses. on this item, the unknown may be calculated through . The solution is, therefore, 0.20.
Opportunity is a measure of the chance of an event to arise. Many occasions cannot be predicted with overall reality. We are able to are expecting only the danger of an event to arise i.e. how likely they're to manifest, using it.
The possibility is the branch of arithmetic regarding numerical descriptions of how in all likelihood an occasion is to arise, or how possibly it's miles that a proposition is actual. The possibility of an occasion various between 0 and 1, where, roughly talking, 0 indicates the impossibility of the event and 1 shows reality.
The probability of an event can be calculated by possibility components via surely dividing the favorable range of effects through the full range of possible outcomes.
