Answer: a) 0.2 b) 0.6
c) The event of selecting red tulip is not likely to occur.
The event of selecting purple tulip is likely to occur.
Step-by-step explanation:
Given : Total number of tulips = 100
The number of red tulips = 20
The number of purple tulips =60
The probability that a randomly selected tulip bulb is red :-

Since 0.2 is less than 0.5.
It means that the event of selecting red tulip is not likely to occur.
The probability that a randomly selected tulip bulb is purple :-

Since 0.6 is more than 0.5.
It means that the event of selecting purple tulip is likely to occur.
Answer:
p=2/3
Step-by-step explanation:
3/4p+1/6=4/6
3/4p=4/6-1/6
3/4p=3/6
3/4p=1/2
p=2/3
D)a Because the square root and square cancel
The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches
Answer:
15
Step-by-step explanation:
For 1 house, the charge just to go to a house is $12.
In each house you made $57.
$57 - $12 = $45
The charge per house just for raking was $45.
You charge $9/hour.
$45/($9/hr) = 5 hours
You shoveled 5 hours in each house.
3 * 5 hours = 15 hours
Answer: 15 hours
