you have n items and how many ways are there to chose r of them
nCr=

remember than n! means n times all numbers before like
3!=3*2*1, 5!=5*4*3*2*1

Answer:x+12
Step-by-step explanation:
-15+9=-6 --------> -6-12=-18
15 represents where he started, then he rises upward 9 and then gets to 6. Afterwards he goes down 12 and ends up at 18 which is 3 feet lower then where he originally started.<span />
Answer:y=44°
Step-by-step explanation:
Sin y =cos [90°-y]
It is Given that sin y =cos (y+2°)
Cos[90°-y]=Cos(y+2°)
90°-y=y+2°
88°=2y
y=44°
Answer:
The distribution is Poisson distribution
Step-by-step explanation:
From the question we are told that
An expected number of fish was caught per hour is 1.5
The distribution that best characterize the number of fish you catch in one hour of fishing is the Poisson distribution
This because generally the Poisson distribution is a distribution that shows the number of times a given event will occur within a defined period of time
