Does sadness cause anger or anger cause sadness??

by my experiance i would say that its sadness that causes anger

yes it does but it depends on the scenario. Let's imagine a person crying and is in grief as someone important to them died. There sadness of this person's death causes anger by the growth of questioning why the person has died. Through this vengeance may also be lead through mixed emotions.

Vice versa, if you imagine a person being angry of being jailed, they might feel sadness to why they've done what they've done.

However, one can stay angry and one can stay sad without having any cause of sadness or anger.

This is theoretically speaking.

the answer is bags.

for this case, we must find the number of deaths per day of the year 2015, in automobile accidents, knowing that 32,400 people died.

knowing that the year 2015 had 365 days we have the following division:

where "x" represents the number of deaths per day.

rounding off we have:

approximately, 89 people per day died in 2015

answer:

89 people per day
