Answer:
Yes
Step-by-step explanation:
The octopus chose the rectangles 68% of the time. From this observation you can tell that the octopus has learned there is food under the rectangular shape. Its cognitive abilities are less than a human's, but they are able to discern a rectangle from a circle with success.
Good luck ^^
F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight

Answer:
32
Step-by-step explanation:
Our total is x.
Maysa took half of the cherries, so there is .5x left.
Nabilla took half of the remaining, so that is .5*0.5x, which is .25x
Abdulla took 3.
Your equation is:
.25x-3=5
.25x=8
x=32
So there are 32 cherries
