53:45 All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample
to make a statistical inference about the mean of the normally distributed population from which it was drawn?

O The margin of error is multiplied by V0.5.
The margin of error is multiplied by V2
The margin of error is multiplied by 0.5.
O The margin of error is multiplied by 2.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

113.42

i hope that is right.

step-by-step explanation:

4932,9180,7625 are divisible by 9
