20+20=40*.1 (10%) =4
40-4=36
The margin of error for a 95% confidence interval is 0.93.
mean (μ) = 23.4, standard deviation (σ) = 7.6, sample (n) = 254, confidence = 95% = 0.95
α = 1 - C = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
The z score of α/2 is equal to the z score of 0.475 (0.5 - 0.025) which is equal to 1.96.
The margin of error (E) is given by:

The margin of error for a 95% confidence interval is 0.93.

Answer:
69%
Step-by-step explanation:
if there are 69 packs of mint gum and 31 packs of friut gum 69+31=100
so 69 out of 100 (packs of mint gum) would be 69% of 100
This is the good part of Trigonometry, actually measuring triangles. It's much better than all the identities around sine and cosine and the rest, which actually have more to do with circles than triangles.
This part of trig has a short menu:
Law of Cosines. Three ways to write it, one is 
Law of Sines: 
Triangle angles: 
and two special cases of the Law of Cosines, the Pythagorean Theorem

and the Collinear Points Theorem:


Here we choose Triangle Angles followed by Law of Sines:
A = 180 - 105 -15 = 60 degrees


Answer: 1.8 cm
