Answer:
(x, y) = (5, 2)
Step-by-step explanation:
<u>Given</u>:
LP = x
MP = 2y+3
NP = y+3
KP = 3x -8
KP = MP, LP = NP
<u>Find</u>:
x, y
<u>Solution</u>:
The given relations between the segment lengths let us write two equations:
KP = MP
3x -8 = 2y +3 ⇒ 3x -2y -11 = 0 [eq1]
LP = NP
x = y +3 ⇒ x -y -3 = 0 [eq2]
__
Subtracting 3 times [eq2] from [eq1] gives ...
(3x -2y -11) -3(x -y -3) = 0
y -2 = 0 . . . . . . . . simplify
y = 2 . . . . . . . . . . add 2
Substituting this value into [eq2] gives ...
x = 2 + 3 = 5
The values of x and y are ...
x = 5, y = 2

Answer:
90%
Step-by-step explanation:
Probability of households with one TV = 35% or 0.35
Probability of households with two sets = 39% or 0.39
Probability of households with three or more = 16% or 0.16
The probability of a household with no TV set = 0.10 or 10% (1 - 0.35 - 0.39 - 0.16)
Therefore, the probability of a household with at least one or more sets = 90% (35% + 39% + 16%) or 100% - 10%.
Probability is the chance that something may occur out of many events. To calculate probability, we divide the number of events by the number of possible outcomes.
make a probability tree it will really help so much
