Find the area of the triangle.
2 answers:
Answer:
16 Unit
Step-by-step explanation:
With P(-2,1) , Q(6,1) , R(4,-3) , S(4,1) , the triangle and its altitude look like the one attached in figure.
The length of base PQ is the difference in the x-coordinates of P and Q,
6-(-2)=6+2=8 , because the y-coordinates are both the same as 1.
The height (the length of altitude RS is the difference in the y-coordinates of R and S,
1-(-3)=1+3=4 , because the y-coordinates are both the same as 4 .
The area is

Answer:
a) correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
b) probability for only 2 or less than 2 surgeries in a given day is 0.0536
Step-by-step explanation:
Given data:
mean number is given as 6.2
correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
we know that variance is given as
hence, standard deviation is given as
thus standard deviation is 2.49
correct option is
Poisson distribution is 6.2 and standard deviation is 2.49
b) probability for only 2 or less than 2 surgeries in a given day is
= 0.002029 + 0.012582+ 0.039006
= 0.053617
= 0.0536
