The table shows the heights of students in a group. student height (in inches) a 49 b 48 c 41 d 45 e 47 what is the mean height of the students in the group? 41 inches 43 inches 46 inches 49 inches

Answer with Step-by-step explanation:

We are given height of students in inches as:

49,48,41,45 and 47

We have to calculate the mean height.

Mean is calculated by sum of all observations over number of observations.

i.e. Mean=sum of all observations/number of observations

Mean height=(49+48+41+45+47)/5

Mean height=230/5

Mean height=46

Hence, mean height of students is:

46 inches

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.

b is the answer that makes most sense
