The answer would be 0.055
Answer:
68% of the distribution will be within one standard deviation of the mean
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Bell-shaped = Normally distributed.
This means that 68% of the distribution will be within one standard deviation of the mean
First subtract 4 from btoh sides of the equation
4 - 4 - 2x < 6-4
-2x < 2
Now divide both sides by -2
x > -1
NOTE: when dividing by a negative as above the inequality sign is flipped.
Answer:
x = 4
A
Step-by-step explanation:
2(4x - 6) = 6x - 4
8x -12 = 6x - 4
8x - 8 = 6x
8x = 6x + 8
2x = 8
x = 4
Hope this helps :)
