Answer:
A, they are skew
Step-by-step explanation:
Skew means that they are not perpendicular and they are not parallel.
Sorry if it turns out wrong.
Answer:
The probability that the difference between the sample mean 
and the true population mean 
is : ![P[|\bar{x}-\mu|\leq0.7]=0.9876](https://tex.z-dn.net/?f=P%5B%7C%5Cbar%7Bx%7D-%5Cmu%7C%5Cleq0.7%5D%3D0.9876)
Step-by-step explanation:
Given :
Population standard deviation 
.
Sample size 
The sample mean standard deviation
To find :
The probability that the difference between the sample mean and the true population mean
Now, the probability that the difference between the sample mean and the true population mean is :
![P[|\bar{x}-\mu|\leq0.7]](https://tex.z-dn.net/?f=P%5B%7C%5Cbar%7Bx%7D-%5Cmu%7C%5Cleq0.7%5D)
, 
is large 
Therefore, the probability
Answer:Me no speak espanol
Step-by-step explanation:
Percent formula : is / of = % / 100
12 is ? % of 200..
is = 12
of = 200
% = x
now sub and solve
12/200 = x / 100
cross multiply because this is a proportion
(200)(x) = (12)(100)
200x = 1200
x = 1200/200
x = 6.......so 12 is 6% of 200 <==
Answer: 243.6
Step-by-step explanation:
For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.
Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.
