Answer:
$23780
Step-by-step explanation:
Given data
Let the original price be x
discount= 20%
price= $19,024
so that
20/100*x=x-19,024
0.2x= x-19,024
19,024=x-0.2x
19,024=0.8x
x= 19,024/0.8
x=23780
Hence the original price is $23780

Answer:
60 Degree,30 degree
Step-by-step explanation:
BD is bisector of ∠ABC
=> ∠ABD = ∠DBC
=> 3x = x + 20
=> 3x - x = 20
=> 2x = 20
=> x = 20/2
=> x = 10
Now,
∠ABD = ∠DBC = x + 20 = 10 + 20 = 30 Degree
∠ABC = ∠ABD+∠DBC = 30+30 = 60 Degree
Events are said to be mutually exclusive if they can not occur at the same time, that is, the probability of those events occurring at the same time is zero.
In the question given above,
P (A) = .2
P (B) = .3
P (C) = .3
P (A U B U C) = .2 + .3 + .3 = .8
Therefore, P (A U B U C) = 0.8.<span />
well, in order to solve this we can put each marble into a fraction.
so for blue it would be 5 over 15 (5/15)
because there are 15 marbles in the bag but only 5 of them are blue!
but if you need a % then just divide the top by bottom
then you get a 33% chance of picking blue! hope this helps!
