On Eduardo's workbench are the following
Maurinko [17]

Answer: 2/5

Step-by-step explanation:

Number of cans of red paint = 3

Number of cans of blue paint = 5

Number of cans of green paint = 8

Number of cans of yellow paint = 4

Total number of cans of paint = 20

The probability that Eduardo will

choose a can of red paint or a can of blue will be:

= P(red) + P(blue)

= 3/20 + 5/20

= 8/20

= 2/5

The probability is 2/5.

A motorboat takes 3 hours to travel 108 kilometers going upstream. The return trip takes 2 hours going
IRISSAK [1]

Answer:

  • 45 km/h and 9 km/h

Step-by-step explanation:

Let the rate of boat in still water be b and the speed of the current be c

  • Speed downstream = b + c
  • Speed upstream = b - c

<u>We got equations for time:</u>

  • 108/(b - c) = 3 ⇒ b - c = 36
  • 108/(b + c) = 2 ⇒ b + c = 54

<u>Add up the equations:</u>

  • b - c + b + c = 36 + 54
  • 2b = 90
  • b = 45 km/h

<u>Then finding the values of c</u>

  • c = 45 - 36 = 9 km/h
