There are two possible ways of getting 2 of the same color.
The chance of getting two white ones is 3/8 times 4/10 which is 0.15
The chance of getting two black ones is 5/8 times 6/10 which is 0.375
0.15+0.375=0.525 which is 21/40
So the answer is A.) 21/40
Both are correct because 3/12 can be simplified to 1/4 :
3÷3=1
12÷3=4
3/12= 1/4
hope this helped
Answer:
Ok
Step-by-step explanation:
it's 5 dollars for 4 pounds of apples
<span>zebra fish a then tetras fish (11 – a)
2.2a + 1.85(11 – a) = 22.80
2.2a + 20.35 – 1.85a = 22.80
0.35a = 2.45
a = 7 zebra and 11 – 7 = 4 neon fish

Answer:
y = 2x + [-3]
Step-by-step explanation:
Slope of the perpendicular line = m = 2
Point = (x,y) = (6,9)
So, x = 6, y = 9
Putting in slope intercept equation
9 = (2)(6) + c
c = 9-12
c = -3
Putting m and c in slope intercept equation
y = 2x + [-3]
