Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
Answer:
Step-by-step explanation:
12+x+10=480
22+x=480
x=458
2(12)+2(x+10)=480
24+2x+20=480
44+2x=480
2x=436
x=218
First, you add them all together, and divide them by the number of quantities there are, so:
9+9+8+11+11+12+12+8= <span>80. Then you divide it by 8 (how many numbers there are) to get 10!</span>
Check the table attached.
The first coordinates of each pair represent the 1.roll, and the second coordinates the 2nd, roll.
All the possible outcomes are {(1, 1), (1, 2).... (6, 5), (6, 6)}, a total of 36, as can be seen in the table.
Each outcome has a chance of 1 out 36 total possible outcomes of occurring.
So the probability is 1/36=0.02778
The answer is A I think hope it helps
