Your pump empties the water from a swimming pool in 6 hours. when your friend's pump is used together with your pump, the pool is emptied in 1.5 hours. how long (in hours) does it take your friend's pump to empty the pool when working alone? hour(s)

(I'm sorry if this is wrong, I'm bad at math but this one was pretty simple really) 6-1.5=4.5

Hope this helps! Let me know

step-by-step explanation:

i just finished that assignment for properties of probability distributions.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
