Answer:

Since BD bisects Angle ABC, Angle ABD = Angle DBC

3x+6=7x-18

Subtract 6 from both sides:

3x+6-6=7x-18-6

3x=7x-24

Subtract 7x from both sides:

3x-7x=7x-24-7x

-4x=-24

Divide both sides by -4:

\frac{-4x}{-4}=\frac{-24}{-4}

x=6

Angle ABD=3x+6=3(6)+6=18+6=24

Angle CBD=7x-18=7(6)-18=42-18=24

Angle ABC=ABD+CBD=24+24=48

What is the probability that a two-digit number selected at random has a tens digit less than its units digit
Reika [66]

The probability that a two-digit number selected at random has a tens digit less than its units digit is 0.2667 (4/15).

A=24B=90\\\\P=A/B\\\\P=24/90\\p=4/15

There are 90 two-digit numbers (99-9). Of these, six numbers are divisible by 15 (15, 30, 45, 60, 75, 90). This is also divisible by 5. Therefore, the preferred case is 30-6 = 24. Therefore, the required probability is 24/90 = 4/15.

The probability of an event can be calculated by simply dividing the number of favorable results by the total number of possible results using a probabilistic expression. Whenever you are uncertain about the outcome of an event, you can talk about the probability of a particular outcome, that is, its potential.
