Answer:
x< -8.125
Step-by-step explanation:
7(x+4) < 2(x-5) -3(x+9)
distribute 7, 2, -3 to the parentheses to the right
7x+28<2x-10-3x-27
add like terms
7x+28<x-37
add x to 7x and subtract -28 to -37
8x<-65
divide both sides by 8
x<-8.125 or (-65/8)
Answer:
The answer is 0.105
Step-by-step explanation:
Let cars =C and motorcycles=M.
now, P(C)=76 percent =0.76
P(M)=12 percent=0.12
P(C∩M)=8 percent =0.08
Then, the probability that a person owns a motorcycle, given they own a car, is a conditional probability given by the definition
P(M/C)=
=
=0.105
Therefore, the answer is 0.105
I believe it is well understood.

Answer:
78.5 km
Step-by-step explanation:
Measured at the airport, the angle between the two planes is ...
180° -60° -50° = 70°
The law of cosines tells us the distance between the planes is ...
d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km
The planes are about 78.5 km apart.
