The roots “per” and “cent” in “percent” together mean “for each 100.” “40 percent of 100” translates to “add 40 for each 100.” Since we only have 100, we only need one 40, so our answer is 40.

Answer:
POISSON DISTRIBUTION
Step-by-step explanation:
When dealing with the number of occurrences of an event over a specified interval of time or space, the poisson distribution is often useful.
Poisson distribution is applicable if:
The probability of the occurrence of the event is the same for any two intervals of equal length.
The occurrence or nonoccurrence of the event in any interval is independent of the occurrence or nonoccurrence in any other interval.
The probability that two or more events will occur in an interval approaches zero as the interval becomes smaller.
Therefore, the appropriate probability distribution is POISSON PROBABILITY DISTRIBUTION.
Answer:
= -1 1/5
Step-by-step explanation:
-3 3/5 ÷ 3
change -3 3/5 into an improper fraction
-3 3/5 = - (5*3+3) /5 = -18/5
-18/5 ÷ 3
copy dot flip
-18/5 * 1/3
rewrite to make the math simple
-18/3 * 1/5
-6 * 1/5
-6/5
now change this back to a mixed number
5 goes into 6 once with 1 left over
=-1 1/5
Answer:
15,20,25,30
Step-by-step explanation:
f (n) = 5 (n + 2)
Let n=1
f (1) = 5 (1 + 2)
= 5(3) = 15
Let n=2
f (2) = 5 (2 + 2)
= 5(4) = 20
Let n=3
f (3) = 5 (3 + 2)
= 5(5) = 25
Let n=4
f (4) = 5 (4 + 2)
= 5(6)=30
