german

Answer:

x = 1

y = 30°

is RS is ⊥ to TU then TS = US so we can use this equation to find 'x':

20x-3 = 5x+12

15x = 15

x = 1

we also know that RS intersecting with TU creates a 90° angle

if 3y = 90 then y = 30

mixer [17]

Answer:

So, the probability is P=0.041.

Step-by-step explanation:

We know that 45% of people in Fast-Food restaurants order a diet drink with their lunch.

We conclude that the probaility p=0.45 that a person order a diet drink.

We calculate the probability that the fourth person orders a diet drink.

We get:

$P=p^4\\\\P=0.45^4\\\\P=0.041\\$

So, the probability is P=0.041.
