Answer:
Step-by-step explanation:
Red:black = 1:1
Red cards = x
Black cards =x
x + x = 48
2x = 48
x = 48/2
x = 24
No. of red cards = 24
No of black cards = 24
Now 8 red cards are removed
So, No. of red cards = 24 - 8 =16
Red: Black = 16:24
Red: Black = 2:3
For 4, the answer should be 3:1
To find that answer take 1.5 and divide it by 0.5
And for 5, the answer would be 3/4
The SAMPLING FRAME is the actual population of individuals, or clusters, from which a random sample will be drawn.
The point slope form is y - y2 = m(x - x2)
