Hello,

g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32

h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0

==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s

25=-16*1.25²+v*1.25
==>v=50/1.25=40

Equation h=-16t²+40*t

A piece of buttered toast falls to the floor 17 times. The toast landed buttered side up 6 times. What is the probability that t

kirza4 [7]

Step-by-step explanation:

Given that,

A piece of buttered toast falls to the floor 17 times. The toast landed buttered side up 6 times.

It means that the total number of outcomes are 17

We need to find the probability that the toast lands buttered side down. Favourable oucome is 17-6 = 11

So, probability is given by :

$P(E)=\dfrac{\text{favourable outcomes}}{\text{total no of outcomes}}$

$P(E)=\dfrac{11}{17}$

So, the probability that the toast lands buttered side down is 11/17.
