Step-by-step explanation:
1-2 that went up once
2-5 that went up 3 times
5-10 that went up 5
and so on
Answer:
the mean number of days absent is 0.72 days ( since 0.72 is not an integer, we can say that is the average number of days absent is close to 1 day)
Step-by-step explanation:
given a random variable X= number of days absent , the mean is calculated as:
mean = ∑ x * p(x) , for all the x possible
where x = number of days absent and p(x) the probability of "x" number of days absent
therefore
mean = 0 * 0.60 + 1 * 0.20 + 2*0.12 + 3*0.04 + 4* 0.04 + 5* 0.00 = 0.72 days
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.
Answer:
No
Step-by-step explanation:
Use the Pythagorean Theorem to check on this.
Does 8^2 + 8^2 = 12^2? Does 64 + 64 = 144? NO. So this is not a right triangle.
