Answer:
So basically the mean is the average number.
Step-by-step explanation:
add all of them then divide by 6 (aka how many fractions)
Let's look at the equation:
0.243x=117.369
Divide each side by 0.243.
X=483
So, the number is 483.
A) 0.8
B) 0.24
C) 0.56
D) 0.44
For A, since 1 in 5 is dry, 4 in 5 are not; 4/5 = 0.8
For B, we know that 30%, 0.3, of the ones that are not dry are contaminated:
0.3(0.8) = 0.24
For C, 100%-30%=70% of wells that are not dry are not contaminated; 0.7(0.8) = 0.56
For D, she will either have contaminated water or no water:
0.24+0.2 = 0.44
