A) 180-125 =55
B) both bottom angles are 55 and the triangle's angles should add up to 180, so 55 + 55 + x = 180. X = 70
C) CAE and CBD are equal so the bottom angle (that was calculated in A) will be the base acute angle —>55
The average speed of the truck is calculated by dividing the total distance traveled in a span of the total time given. From the given above, the total distance traveled is
total distance = 203 mi + 243 mi = 446 mi
and the total time it took for the whole trip is
total time = 3.5 h + 4.5 h = 8 h
The average speed is therefore,
average speed = 446 mi/8 h = 55.75 mi/h
Thus, the answer is letter A.
Let's put all of these into percent form.
P(Guilty) = 0.25 = 25%
P(Innocent) = 55%
P(Retrial) = 1/5 = 0.2 = 20%
Next, we need to order them from least to most likely. The least likely event to occur would be the smallest percent, then the next smallest, etc.
Order: Retrial, Guilty, Innocent
Hope this helps! :)
A negative times a negative is a positive so...
( - ) ( - ) ( - ) ( -10x ) = -5
10x = -5
x = -5/10
x = -1/2
I believe it would be B observational sampling
