Answer:
548 ft
Step-by-step explanation:
70+70+84+84+120+120
P(arrives on time given leaves on time)=
P(B | A)= P(B n A) / P(A)
= P(A n B) / P(A)
= 0.36 / 0.9
= 0.4
2x-y=3
use the substitution method
2(2)-y= 3
4-y= 3
move 4 to the other side
sign changes from +4 to -4
4-4-y= 3-4
-y= 3-4
-y=-1
mutiply both sides by -1 to get +y
(-1)(-y)= (-1)(-1)
y= (-1)(-1)
Answer: y= 1
Methodically:
1 = 1*1 = 1 factor
2 = 1*2 = 2 factors
3 = 1*3 = 2 factors
4 = 1*4 = 2*2 = 3 factors
Therefore, 4 is the lowest number with 3 different factors
