Answer:
D. scalene triangle
Step-by-step explanation:
This triangle has sides that all have different lengths. Therefore, this triangle is a scalene triangle.
Tips:
Isosceles triangle - two sides have equal lengths
Equilateral triangle - all three sides have equal lengths
I hope this helped! :)
Answer:
max 151.02
after 6.04
Step-by-step explanation:
You would need the table to figure this problem out, but here we go!
15000×.018= 270
15000×.020= 300
15000×.023= 345
270+300+345= $915
Answer:
The average number of days that will pass between measurable rain is 7.5.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
The expected period between the event happening is 
During the dry month of August, one U.S. city has measurable rain on average only 4 days per month. Assume all months have 30 days.
This means that

(a) If the arrival of rainy days is Poisson distributed in this city during the month of August, what is the average number of days that will pass between measurable rain? *

The average number of days that will pass between measurable rain is 7.5.
