Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :
3.1433174885
= 3.14
Answer:
S = 9180°
Step-by-step explanation:
Given the following data;
Number of sides = 53
To find the sum of interior angles of a 53-gon;
Mathematically, the sum of the interior angles in a regular polygon is given by the formula;
S = 180(n - 2)
Where;
n is the number of sides.
S is the sum of the interior angles
Substituting into the formula, we have;
S = 180(53 - 2)
S = 180 * 51
S = 9180°
First we have to know the Pythagoreans theorem which is
a^2+b^2=c^2
7^2+8^2=c^2
49+64= 10.63
Hope this helps
