Answer:
Step-by-step explanation:
x is clearly 42° because WU is an angle bisector of YWZ (which is 84, and bisecting means half of 84, that is 42)
now, for m of WYL
notice, YLW = 90°
also, UWL = 42°
name the intersection point of YL and WU as O in your mind
Apply angle sum property of a triangle for triangle WOL
angle WOL + angle UWL + angle YLW = 180
angle WOL + 90 + 42 = 180
angle WOL = 180 - 132
angle WOL = 48
now focus on line LOY
since LOY is a line, the angles a line intersecting it forms a linear pair, i.e
angle WOL + angle YOW = 180
48 + YOW = 180
angle YOW = 132
Now, apply angle sum property for triangle YOW
angle YOW + angle YWO (x) + angle WYO (or WYL) = 180
132 + 42 + WYO (or WYL) = 180
WYO (or WYL) = 6°

12 Bags of concrete will weight about 276.923 pounds. You need to do 600 divided by 26 for an individual bag. Then multiply the answer you get from it by 12 to find out the amount for 12 bags.
Answer:
Option C) 0.1804
Step-by-step explanation:
We are given the following information in the question:
Mean customers enter the tellers’ queue every five minutes = 2
Thus, the number of customers that enter the tellers’ queue is Poisson distributed
Formula:
We have to evaluate:
0.1804 is the probability that exactly three customers enter the queue in a randomly selected five-minute period.
Thus, the correct answer is
Option C) 0.1804
Answer:
f(5) = 5
Step-by-step explanation:
To evaluate f(5) , substitute x = 5 into f(x), that is
f(5) = 5² - 20 = 25 - 20 = 5
