To find the mean, you add all the elements together, then divide by the number of elements.
Like this:
(45+48+49+40+53)/5=47
in other words the correct answer is 47 inches.
EDIT: Did the foolish mistake, of using the wrong numbers the first time. Fixed now and the answer is correct.
Answer:
x = - infinity to 99
Step-by-step explanation:
The values of x must less than 100.
(x,y)
to be a function
for every x, ther must be only 1 y to corespond to it
basically, x must NEVER repeat with a different y
list them
ah, we see (1,1) an d(1,-1)
also (4,2) and (4,-2)
double offense
1 repeats with 1 and -1
4 repeats with 2 and -2
not a function
domain is all x values
range is all y values
if they repeat, don't list them
domain=(0,1,4)
range=(-2,-1,0,1,2)

Answer:
m = 35
n = 110
Step-by-step explanation:
Adjacent angles in a parallelogram are supplementary.
n° = 180° -70°
n = 110
Opposite angles in a parallelogram are congruent.
2m° = 70°
m = 35 . . . . . . divide by 2°
