Solution :


= 0.0836
P(B)= P(coin
chosen and 4 heads in 10 trails) + P(coin
chosen and 4 heads in 10 trail) + P(coin
chosen and 4 heads in 10 trail)



P(A|B) = 


Answer:
c
Step-by-step explanation:
The slope of the line is 4/10
remember: rise over run
Ok, so from previous question
(x-h)^2=4p(y-k)
distance from focus to directix is 2
2/2=1=p
1>-1
focus is above the vertex
1 unit down from (0,1) is (0,0)
vertex at (0,0)
since focus is above, p is positive
(x-0)^2=4(1)(y-0)
x^2=4y
4y=x^2
divide both sides by 4
y=(1/4)x^2
f(x)=1/4x^2
2nd one is answer
Speed of Bob = 5/1.25 = 4miles/h
Speed of Stan = 3/ (5/6) = 3 * 6 / 5 = 18/5 = 3.6 miles/ h#
Bob runs faster than Stan
