Answer:
y=6,95x+35
y=6,95*5+35=69,75 for 5 hours
for 6 hours y=76,7
for 7 hours y=83.65
for 8 hours y=90,6
Step-by-step explanation:
My answer from your question is 5
If 3, 6, 9, 12, 15, and 18 are multiples of 3 between 1 and 20, and 5, 10, 15 and 20 are multiples of 5 between 1 and 20, then you add the amount of multiples together to get 10.
10 over 20 as a fraction can be simplified to 1 over 2 which is 50%.
This means that there is a 50% chance of drawing out a multiple of 3 or 5.
I hope this helps
