To find the mean:
Take <span>3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together
=83
Now you divide 83 by the number of terms in the sample set, which is 20.
83/20 = 4.15
For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.
final answer= 4.2 </span><span />
Answer:
9 sides
Step-by-step explanation:
Each interior angle of a regular polygon is 100 degrees larger than the exterior angle determine the number of sides of the polygon
Interior angle + exterior angle =
180°
Let x be the exterior angle.
Exterior angle = 180-x = 100 + x
= 180 - 100 = x + x
80 = 2x
x = 80/2
x = 40
Number of sides of the polygon =
= 360°/Exterior angle
Exterior angle = 40°
= 360/40 = 9 sides
From zero, rise(up) one and run(right) four with the y intercept being on -4 :)
