52 lbs you get the answer by adding the two weights of the bags
The answer is 57.49°
57°29'38" = <span>57° + 29' + 38"
</span>
1° = 60'
x° = 29'
1 : 60 = x : 29
x = 29 * 1 : 60 = 0.48°
<u>29' = 0.48°</u>
1° = 3600''
x° = 38''
1 : 3600 = x : 38
x = 38 * 1 : 3600
x = 0.01°
<span><u>38'' = 0.01°</u>
</span>
57°29'38" = 57° + 29' + 38" = 57° + 0.48° + 0.01° = 57.49°

Answer: -0.196</h3>
======================================================
Explanation:
We're conducting a one proportion Z test.
The hypothesized population proportion is p = 0.53, which is not to be confused with the p-value (unfortunately statistics textbooks seem to overuse the letter 'p'). Luckily this problem is not asking for the p-value.
The sample population proportion is
phat = x/n = 41/79 = 0.518987 approximately
The standard error (SE) is
SE = sqrt(p*(1-p)/n)
SE = sqrt(0.53*(1-0.53)/79)
SE = 0.056153 approximately
Making the test statistic to be
z = (phat - p)/(SE)
z = (0.518987 - 0.53)/0.056153
z = -0.19612487311452
z = -0.196
Which is approximate and rounded to 3 decimal places.
They have 58 sides all together
