Answer:
7740 degrees.
Step-by-step explanation:
The sum of the exterior angles of all polygons add up to 360 degrees.
So the number of sides and the number of interior angles in this polygon = 360 / 8 = 45.
Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles
= 172 * 45
= 7740 degrees,
Hi!!! So to do this problem, you need to find the mean values for each sample. I will walk you through finding the mean of sample 1: first you want to add all of the values for sample 1, which are 4,5,2,4 and 3. Once you add those values you get 18. Then you must divide that 18 by the number of terms you added. The numbers you added were 4,5,2,4 and 3 like I said earlier which is 5 numbers. You divide 18 by 5 to get your mean, which is 3.6
Answer: (B) Sample 2
sample 1 mean = 3.6
sample 2 mean = 4.2
sample 3 mean = 3.8
sample 4 mean = 4
Answer: .3 as a fraction is 3/10
3/10 and .3 as a percent is 30%
Answer:
arc PST = 254°
Step-by-step explanation:
arc QPT = 180° because it is a diameter
arc PQ = 74°
arc PT = 180° - 74° = 106°
arc PST = 360° - 106° = 254°
You first need to know how much miles it takes on the trail. Then you look 20 x 3 is one hour. And if the 3 group said it takes 2 hours waking for them its like this, the first group takes one hour to go thru the trail, but the second group takes and hour and half the 3 group takes 2 hours.
I wish this helps. :)
