Answer:
The interval that contains the middle 68% of the heights is from 52 inches to 60 inches.
Step-by-step explanation:
The empirical rule states that, for a normally distributed variable:
The middle 68% of the measures are within 1 standard deviation of the mean.
The middle 95% of the mesures are within 2 standard deviations of the mean.
The middle 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Normally distributed with mean 56 inches and standard deviation 4 inches.
So the interval that contains the middle 68% of the heights is from 52 inches to 60 inches.

Answer:
x= -0.715
Step-by-step explanation:
6^x+2 = 10
<u>Apply the log rule:</u>
<em>a^X = Y</em>
<em>X log a = log Y</em>
<em>X = log a/log Y</em>
6^x+2 = 10
(x+2) log 6 = log 10
x+2 = log 10/log 6
x+2 = 1.285
x = 1.285 - 2
x = -0.715
Therefore, the second option is correct where x is equal to -0.715.

Yeah I feel like lately I've been overdoing it a bit. I've been playing video games way longer then I used too, then again I have nothing better to do, but it's time I start taking a little more care of my body. Thanks for the nice words! 2+2 = 4.
