Answer:
9- 8
Step-by-step explanation:
3 Rd side would be
13sq=12sq+xsq
Xsq=169-144
X=5
Cot theta = adj side/opp side= 5/12
Part a: what you have to do is add up all of the vehicles and you get 150. Then it says "approximate probability of a passenger car..." so you would take the number of passenger cars (which is 112) and put that number over 150. 112/150. you would get 0.746666666667 and round that up and you would get 75% (B)
Part b: you do the same thing but change the passenger car number into light truck number. (which is 18) 18/150 0.12 which is 12% (B)
Answer:
5:7
Step-by-step explanation:
Answer:
k<3.5 or k>3.5
Step-by-step explanation:
k²-7k+12.25>0
(k-3.5)²
k²-7k+12.25
k²-2k·3.5+(√12.25)²
(k-3.5)²
k-3.5<0 or k-3.5>0
k-3.5 or k-3.5
