11.2 ft
If it is a ratio just find what the scale number is by doing 14/40 = .35
Then .35 * 32 = 11.2
Answer:
Step-by-step explanation:
Given Parameters
Mean, 
= 180
total samples, n = 20
Standard dev, 
= 30
= 1 - 0.95 = 0.05 at 95% confidence level
Df = n - 1 = 20 - 1 = 19
Critical Value, 
, is given by
a).
Confidence Interval, 
, is given by the formula
b).
Critical Value, 
, is given by
Confidence Interval, , is given by
= 180 +/- 14.0403
= 165.9597 < < 194.0403
Step-by-step explanation:
Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S
so we get as,
==> x+7 = (-2)^5
==> x+7 = -32
==> x = -32-7
==> x = -39
hence, x = -39
Option A.) is correct.
