Answer:
A. 4/8 + 2/4 =1 B.5/8 + 1/4 =0.875
C.6/8 + 3/4 =1.5 D.7/8 + 2/4 =1.375
Answer:
x = -3/8
Step-by-step explanation:
4(3 - 2x) = 15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 =15-12
-8x =3
Divide by -8
-8x/-8 = 3/-8
x = -3/8
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
