General line, perpendicular to 6x+5y=-3: y=5/6x+b
Steps:
1: Compute the slope of 6x+5y=-3: m= -6/5
2: Compute the slope of the perpendicular line: mp= 5/6
3: Line with slope m= 5/6: y= 5/6x+b
Description:
To find the slope perpendicular first you need to compute the slope of the equation. Then compute the slope of the perpendicular line. Then you will get the half answer: Line with slope m. You will now get your full answer. That is y=5/6x+b.
Answer: y=5/6x+b

Answer:
D. 9990 possible combinations
Step-by-step explanation:
The first digit has 10 choices (can be all of them), the second digit also has 10 choices. The third and fourth digits also have 10 choices.
Multiply them together you get 10*10*10*10 = 10000 possible combinations.
But since all 4 characters cannot be the same, we subtract 10 from 10000 (there are 10 combinations which the 4 characters are the same: 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, and 0000) and we get 9990.
No, that would be an invalid inference because he actually sampled from only half of the total population not the entire population.
so 12% of the 50% he sampled would be valid, but since he did not use the entire population, the results cannot affect all of them.<span />
