notka56 [123]

Answer:

Javier rode bike 34 minutes before lunch.


Step-by-step explanation:


Let the number of minutes Javier rode the bike after lunch be = x minutes


Then according to question number of minutes he rode the bike after lunch

= 5x-1


Total number of minutes he rode bike = 41 min

Therefore,

x+5x-1 =41


On solving


6x= 41+1 =42


Divide both side by 6 we get

x= 7


Number of minutes he ride before lunch

= 5(7)-1 = 35-1=34 min

When rolling a number cube 600 Times, predict the relative frequency of rolling a 3 or 6
Flauer [41]

Answer:

The frequency of rolling a 3 or a 6 would be the same even if you try thousands or millions times.

The probability of rolling a 3 is: 1/ total outcomes probability = 1/6

The probability of rolling a 6 is: 1/ total outcomes probability = 1/6

The probability of rolling a 6 or a 3 = 2/ total outcomes probability = 2/6 = 1/3

Therefore, if you rolling the cube 600 times, the probability of rolling a 3 or a 6 is still 1/6. If 3 and 6 are both allowed, the probability would become 1/3

Hope this helped :3
