Answer:

assumption:

drinks are selected with replacement from refreshment stand

note:

i think "choosing" is poorly worded in the problem

use complement of everyone selecting a unique drink:

1-(8*7*6*5)/8^4 = 151/256 = 0.5898

answer -> D 0.59

0.54723 divided by 2<br> Pls show steps
Nina [5.8K]

Answer:

0.54723 divided by 2 = 0.273615

Step-by-step explanation:

0.54723/2 = 0.273615

There is not much to show regarding steps, but this might help:

Dividing something by 2 means spliting the original value in half. This means that the product of the number of the original value that was divided by two is half of the orginial value. This means that <u>0.273615 + 0.273615 = 0.54723(the original value)</u> because two halves make a whole.

-5c/8 = 20 what is the value of c
lorasvet [3.4K]

Please try to follow me, as I demonstrate a method of solution. 
This could get complicated.  I'll try to go slowly, and you must
stop me if I do anything that's not clear.

Ready ?

You said that                    -5c/8  =    20

Multiply each side by  8:  -5c     =  160

Divide each side by  5 :   - c      =    32

Multiply each side by -1 :   c      =  -32

A ball is launched upward from the ground with an initial velocity of 20 ft/s. The height of the ball at time t is represented b
Anastaziya [24]

Answer:

1.-t₁  =  0,625 s

2.-h(max)  =  6,25 f

3.-t = 1,25 s

Step-by-step explanation:

V₀  =  20 f/s

h(t)  =  - 16*t² + 20*t

h(max)  =  ??

h´(t)  = - 32*t + 20

h(max) will occurs when  V = 0   dh/dt  = 0  then

- 32*t  + 20  = 0

- 32*t  =  -20

t  =  20/32

t₁  =  0,625 s

h(max) = h(0,625)    =  - 16*(0,625)² + 20*0,625

h(max)  =  - 6,25  +  12,5

h(max)  =  6,25 f

c) The ball will hit the ground

t = 2*t₁

t  = 2*0,625

t = 1,25 s
