Direction: Opens up
Vertex: (0,0)
Focus: (0,2)
Axis of Symmetry: x=0
Directrix: y=-2
Answer:
a) 
b) 
Step-by-step explanation:
a) Lets denote 
the cumulative distribution function of X. Note that for any value a between 0 and I/2, we have that 
is the probability for the stick to be broken before the length a is reached following the stick from one starting point plus the probability for the stick to be broken after the length I-a from the same starting point. This means that 
b) Note that, as a consecuence of what we calculate in the previous item, X has a uniform distribution with parameter I/2, therefore, the probability density function f is
f(x) = 1/(I/2) = 2/I
Answer:
88059595400 hectares
Step-by-step explanation:
Convert 340 million square miles into hectares.
1 square mile = 258.99881 hectares
340,000,000 square miles = 88059595400 hectares
The forest is 88059595400 hectares.
let
x-------> walnuts that Mario eats in a week
y-------> walnuts that Yolanda eats in a week
we know that
x=2y-------> equation 1
y=6*7-------> y=42 walnuts
substitute the value of y in equation 1
so
x=2*42-----> x=84 walnuts
therefore
the answer is
Mario eat in a week 84 walnuts
Answer:
The total amount paid by Jill = $ (3 d)
Step-by-step explanation:
Here, the cost of 1 book = $ d
Now, the number of books purchased by Jill = 3
So, the total cost of 3 books = 3 x ( Cost of 1 book)
= 3 x ($d) = 3 d
So, if Jill purchased 3 books, the total amount paid by her = $ (3 d)
