8 red, 6 green......14 total
P(green) = 6/14 which reduces to 3/7
replaced
if the ball is being replaced each time, the sample size does not change
therefore, the probability of all 5 balls being green is (3/7)^5 = 3^5/7^5 =
243/16807 = 0.014 <==
Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
the total number of marbles in the bag is 12 . so the probability of getting a green marble at random is 4/12 which resluts to 1/3
Answer:
Step-by-step explanation:
3x=2, 8+4=12,30-6=24,27/3=9,6x5=30,14
Answer:
y = 3x -31
Step-by-step explanation:
y=mx+b
m=3
5 = 3*12 +b
b = 5 - 36
b = -31
y = 3x -31
