Divide by 3 on both sides:

Square root both sides:

Take away 3 from both sides:

Divide by 2 on both sides:

Answer:
Total number of balls = 50
Balls numbered as multiple of 10 = 5
Balls with red dot on them = 6
Balls numbered as multiple of 10 and having red dot on them = 1 (i.e. Ball with number 40 on it)
Probability of Ball being numbered as multiple of 10 = P(T) = 5/50 = 1/10
Probability of Ball being marked by the dot = P(D) = 6/50 = 3/25
Probability of Ball being numbered as multiple of 10 and having a red dot on it = P (T ∩ D) = 1/50
The "or" ,"union" of two events can be expressed as:
P(T ∪ D) = P(T) + P(D) - P (T ∩ D)
Using the values, we get:
P(T ∪ D) =
Thus, the probability that the ball is numbered with a multiple of 10 or has a red dot is 1/5 or 0.2
Answer:
3x−4>11
Step 1: Add 4 to both sides.
3x−4+4>11+4
3x>15
Step 2: Divide both sides by 3.

x>5
Answer:
Speed of Charles = 12 Km per hour
To convert it into meters per minute, we follow the following procedure
1 Km =1000 meter
1 hour = 60 minute
Now 12 Km per hour = 
= 12,000 ÷ 60
= 200 meter per minute
Answer:
A rational exponent is an exponent that is a fraction. If the fraction has an even denominator, the root will be of an even number (like the square root, the 4th root, etc.). Think about it when you square something: -2 • -2 = 4, 2 • 2 = 4. No matter the sign, any number multiplied by itself an even number of times will make a positive number. So, you can't take the square root of a negative number because it is impossible to get a negative number when squaring! This applies to ALL even roots/exponents. So, (-1)^½ does not exist! Look: (-1)^½ becomes √(-1) which is an imaginary number!
