Answer:
C
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, so n = 6
sum = 180° × (6 - 2) = 180° × 4 = 720° → C
3/5 of an hour (0.6 hours)
First, find how many words Nick types in an hour by multiplying 275 * 60.
Nick types 16,500 words per hour.
Now just divide 9,900 by 16,500.
It takes Nick 3/5 of an hour to type 9,900 words. (0.6 hours)

The scatter plot has been attached
Answer:
Options C, D & E are true
Step-by-step explanation:
Option A is wrong because from the scatter plot, only four athletes were faster in the second race than in the first one.
Option B is wrong because only 1 athlete had his second race time differing from the first race time by exactly 2 seconds.
Option C is true because exactly 9 of the times for the first race were at least 16 seconds
Option D is true because there are exactly 3 athletes who had the same time in both races
Option E is true because 8 of the times for the second race were less than 17 seconds
(2,225)(5,480)
slope = (480 - 225) / (5 - 2) = 255/3 = 85
y = mx + b
slope(m) = 85
use either of ur points...(2,225)...x = 2 and y = 225
now sub and find b, the y int
225 = 85(2) + b
225 = 170 + b
225 - 170 = b
55 = b
equation is : y = 85x + 55...but we need this in standard form
y = 85x + 55
-85x + y = 55...multiply by -1 to make x positive
85x - y = -55 <== ur standard form equation
===============
function notation : f(x) = 85x + 55
===============
to graph : y = 85x + 55
ur slope is 85...ur y int is (0,55)...ur x int is (-11/17,0)
ur gonna start at (-11/17), and since ur slope is 85, u will go up 85 units and to the right 1 unit and up 85, and to the right 1...and u should cross the y axis (0,55)...I suggest going to desmos graphing calculator so u can see the graph
401 ÷ 6 = 66.83 so id probably round it up to 66
