Answer:
1/10
Step-by-step explanation:
P(1st marble yellow) = Number of yellow / total
= 2/5
We keep the marble. Now there are four marbles in a bag. Three are green, and one is yellow.
P(2nd marble yellow) = Number of yellow / total
=1/4
P (1st yellow, keep, 2nd yellow) = 2/5 * 1/4
= 2/20 = 1/10
Answer:

Answer:
1 = 24 degrees
2 = 156 degrees
Step-by-step explanation:
Solve the equation for x:
x - 15 +4x = 180
5x = 195
x = 39
so 1 = (39-15) = 24 degrees
so 2 = (4x39) = 156 degrees
Answer:Smaller value is 4 yards.
The larger value is 6 yards.
Step-by-step explanation:
Let L represent the length or larger value of the rectangular plot.
Let W represent the width or smaller value of the rectangular plot.
The area of the rectangular field is expressed as
LW = 24 - - - - - - - - - - 1
The formula for determining the perimeter of the rectangular fence is expressed as
2(L + W) = 20
L + W = 20/2 = 10
Substituting L = 10 - W into equation 1, it becomes
W(10 - W) = 24
10W - W² = 24
W² - 10W + 24 = 0
W² - 6W - 4W + 24 = 0
W(W - 6) - 4(W - 6) = 0
W - 4 = 0 or W - 6 = 0
W = 4 or W = 6
Substituting W = 4 and W = 6 into
L = 10 - W, it becomes
L = 10 - 4 or L = 10 - 6
L = 6 or L = 4
