Answer:
1/4n - 3
Step-by-step explanation:
1/4 of a number means multiplying 1/4 to n. So we can write 1/4n. Now we write the subtract 3 portion. 1/4n - 3.
Answer:
The correct option is b. approximately 68% of the data falls within 1 standard deviation (+-1) of the mean
Explanation:
According to the empirical rule of normal distribution:
1. Approximately 68% of the data falls within 1 standard deviation
of the mean
2. Approximately 95% of the data falls within 2 standard deviations
of the mean
3. Approximately 99.7% of the data falls within 3 standard deviations
of the mean.
Therefore, among the given options, only option b adheres to the empirical rule of the normal distribution. Therefore, the option b is correct
For the A parts just make all the second numbers negative example: if it were 5,1 make it (5,-1) and for the B part make all the first numbers a negative example: if it were 5,1 make it (-5,1)
Well the opposite of a positive number is a negative, so if I am correct,
-30 / -6 would be 5, and 5 + -8 would be -3.
So -3 would be your answer.
