International travel is usually more expensive than domestic travel. A recent survey found that the average per-person cost of a 12-day internationalvacation is $1,755. This includes transportation, food, lodging, andentertainment. a. If the data are normally distributed with standard deviation $390, find thepercentage of vacationers who spent less than $1,200 per day. Round to thenearest hundredth of a percent. b. Find the per-day expense for one of these travelers who had a z-score of-2.1.c. If the data are normally distributed with standard deviation $490 instead of$390, would the answer to question 7b become lower or higher?

can you hlep me do homework?

step-by-step explanation:

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

the answer is 31.27mph

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
