55% were in the rest of the train. it says "d" though, so I can't tell you the exact number.
Answer: 1/3
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal.
For example, if slope of line A is a/b, then slope of line B which is perpendicular will be -b/a.
Substitute 1 and 3 for a and b. Apply the formula and get 1/3.
To find the difference of numbers, all you have to do is subtract them
827 - 533
Subtract
Final Answer: The difference between 827 and 533 is 294
People who never develop symptoms or are not yet showing symptoms (pre-symptomatic) might not know that they are infected but can still spread rona to others. Masks also offer protection to the wearer.
Mean = (total of contributors) / (number of contributors)
For the 6 people in the room, you have
40 = (total of contributors) / 6
(total of contributors) = 6*40 = 240
A 60-year-old left the room, decreasing the total of contributors by 60.
(new total of contributors) = (total of contributors) - 60
(new total of contributors) = 240 - 60 = 180
Then the new mean is
(new mean) = (new total of contributors) / (new number of contributors)
(new mean) = 180 / 6 = 36
The mean age of the remaining 5 people is 36.
