Step-by-step explanation:
With each draw, the probability of selecting a green marble is 2/3 and the probability of selecting a yellow marble is 1/3.
To pick two of the the same color, they can either pick green twice or yellow twice.
P = (2/3)(2/3) + (1/3)(1/3)
P = 5/9
To pick two different colors, they can either pick green first then yellow, or yellow first then green.
P = (2/3)(1/3) + (1/3)(2/3)
P = 4/9
Expected value for Derek is:
D = (5/9)(-1) + (4/9)(1)
D = -1/9
The expected value for Mia is:
M = (5/9)(1) + (4/9)(-1)
M = 1/9
A because u can clearly see how the line is connected and if u count to where the line is u will see that it is A
Step-by-step explanation:
just add all the given angles and equate it with 540° and then find x
x/2 + x/2 + x - 25 + 100 + x - 15 = 540°
3x + 60 = 540°
3x = 540 - 60
x = 480/3
x = 160°
on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.
Answer:
x^2+y^2=(x^2+y^2-2y)^2
Step-by-step explanation:
Here we are given that
r=1+2sin
we know that the polar cordinates are represented as
x=rsin
y=rcos
Also squaring both and adding them gives you ,
Hence
also r=1+2sin
1+2sin =
Also ,
r = r=1+2sin
also sin =
Hence replacing sin we get
