First deal there are 14 red and 6 black so fraction of red = 14/20 or 0.7
second deal there are 20 red and 10 black so fraction of red = 20/30 or 0.67
0.67 is closer to 1/2 that 0.7 so
c is the correct choice
Answer:
The required sample size is 42.
Step-by-step explanation:
Please see the attached picture for the complete answer.
If you would like to solve 9 <= 17 - 4x for x, you can do this using the following steps:
9 <= 17 - 4x
4x <= 17 - 9
4x <= 8 /4
x <= 8/4
x <= 2
The correct result would be x <= 2.
Answer:
B. 
D. 
Step-by-step explanation:
The solution of the system of inequalities is shown by the area shaded.
All the points of the co-ordinate plane that lies within this area are the solutions of the system.
From the choices given, the points
and
is within the area of the shaded region. So, these are the solutions for the given system of inequities.
