Answer: There are 10 sides
---------------------------------------------
x = measure of each interior angle
y = measure of each exterior angle
We know that x = 4y as "each interior angle is four times the measure of each exterior angle"
The interior and exterior adjacent angles are supplementary
x+y = 180
4y+y = 180
5y = 180
5y/5 = 180/5
y = 36
If y = 36, then
n = 360/y
n = 360/36
n = 10
The answer would be "both groups show about the same average time"
Well, Since every 1 person throws away 4.5 × 10² g trash each day (365 days in each year), You would times 3.2×1063.2×106 by the 4.5 × 10² g to get how much trash was thrown away each day and then times that by 365 to figure how much trash was thrown away the entire year

Answer:
20
Step-by-step explanation:
to find the mean, it means to find the average.
steps:
first, you add up all the numbers.
then you divide that total number by the total number of numbers you have.
and that is ur answer!!
17+19+21+23=80 add up all numbers
80÷4=20 divide total by the amount of numbers
The average/mean is 20.
plz give brainliesttttt
