Answer:
Detailed steps:
We know that the number of total events is
and that the probability of a certain event E (for example, "<em>the enemy drops two objects</em>") is computed as the number of times event E occurred, divided by the total of events N=80.
Then:
and
We can verify by checking that adding all probabilities sums up to one.
A point on the edge of the roller travels the circumference of the roller in 1 revolution, so that its linear velocity is
(10 rev/s) * (2*(14.25 cm)*pi cm/rev) = 285 pi cm/s
or about 895.4 cm/s.
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
Answer:
A. 26 1/2
Step-by-step explanation:
change denominator so they can be the same
3/4*3 = 9/12
1/3*4 = 4/12
Add the whole numbers : 10 +15=25
9/12+4/12= 13/12 so 1 1/12
26 1/12
