The mean of sample x is 5.83
The standard deviation is 5.63
<h3>What is standard deviation?</h3>
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given:
Frequency: 2 2 4 13 13 1
If x is the pair of sneakers owned of the frequency,
mean = 2+2+4+13+13+1/5
= 35/6
= 5.83
The standard deviation is equal to 5.63.

Answer:
A___B___C
AC = AB+ BC
3x +12 = ( 14) + (3-2x)
3x + 12 = – 2x + 17
3x + 2x = 17 - 12
5x = 5
x=5/5
x = 1
AC = 3x + 12 = 3(1) + 12 = 3 + 12= 15
I hope I helped you^_^
The book is 540 pgs.....she has read 405....that leaves (540 - 405) = 135 pgs left to read.
135 / 540 = 0.25 = 25% <== what she has left to read
To do this, start simple first.
Add 10 and 2
10 + 2 = 12
Now add the fractions:
9/12 + 1/12 = 10/12
Simplify: 5/6
Nate will be 12 and 5/6 years old.
