The appropriate choice is z = 1.41.
The empirical rule tells you 68% of the distribution is within 1 standard deviation, so p(z > 1) ≈ 0.17. This means the z value is more than 1 for the probability to drop to 0.08. The only choice that is greater than 1 is 1.41. (The number is actually about 1.40507.)
Area(A)=192ft^2
Width (W)=?
Length (L)=3W
First we must find what the width and length are to find perimeter (P=2L+2W).
A=LxW
192=(3W)(W)
192=3W^2
192/3=3W^2/3
64=W^2
8=W can only use positive solution of 8 because distance is positive.
L=3W=3(8)=24
P=2L + 2W
P=2 (24)+2 (8)
P=48+16=64ft

Fraction: 5/7
Explanation:
An absolute value function in the form ...
f(x) = a|x -h| +k
will have its vertex at (x, y) = (h, k). The sign on scale factor "a" will tell you whether it opens upward (a > 0) or downward (a < 0).
If a is positive, the vertex is a minimum, and the range is [k, ∞).
If a is negative, the vertex is a maximum, and the range is (-∞, k].
