Notice that the box has a total os 4 + 5 + 3 = 12 balls, since there are 4 that are yellow, then, the probability to randomly obtaining a yellow ball in a single draw is:
therefore, the probability is 0.33 = 33%
If bd=bc,bd=5x-26,bc=2x+1,and ac=43 find ab
2 answers:
Given
bd=bc , bd=5x-26, bc=2x+1,and ac=43
find out the value of ab.
To proof
As given in question
bd=bc
put the value as given in the question
5x - 26 = 2x +1
5x - 2x = 26 +1
3x = 27
x = 9
Put the value of x in the bc equation
bc = 2× 9 + 1
= 19
as shown in diagram given below
ac = ab + bc
putting the value as given above
43 = ab + 19
ab = 43 -19
ab = 24
Hence proved

Answer: C) 0.833%
Step-by-step explanation:
Given: Cost price of house = $120,000
The rate of increase of its cost = 10%
Therefore, the increase amount of house per year =10% of $120,000
Now, the amount increase each month=
Let r be the rate of growth each month, then
r% of $120,000=1000
