A 13 foot long ramp rises 5 feet from the first floor to the second floor. What is the distance from the base of the ramp to the
1 answer:
Answer:
The answer to your question is base = 12 feet
Step-by-step explanation:
Data
Length = 13 ft
height = 5 ft
base = ?
Formula
c² = a² + b²
Solve for b
b² = c² - a²
Substitution
b² = 13² - 5²
Simplification
b² = 169 - 25
b² = 144
b =
Result the distance from the base to the bottom of the first floor is
b = 12 ft

So,
The probability of drawing a yellow marble is
.
Since he replaces the marble after it is drawn out, the probability of drawing another yellow is the same:.
The probability of drawing a red marble is
.
In order to get the probability of drawing 2 yellow marbles and 1 red marble, given that each marble is replaced after it is drawn out, we must multiply the fractions together.
Because the order of the marbles doesn't matter, we will multiply the probability by 3.
