Answer:
Sum = 2,340°
Step-by-step explanation:
Sum of interior angles = 180·(n-2),
where n is the number of sides the polygon has
Sum = 180·(15-2)
Sum = 180·13
Sum = 2,340°
Answer:
Option B) 0.1032; fail to reject 
Step-by-step explanation:
We are given the following information in the question:
We used two tailed z-test to perform the hypothesis.

Level of significance, α = 0.05
We have to calculate the p-value.
We calculate the p-value from the normal standard z-table.
p-value = 0.1032
Since,
p-value > Level of significance
We fail to reject the null hypothesis and accept it.
Option B) 0.1032; fail to reject null hypothesis
The answer is 25%
you take (425/1700)*100
0.25 * 100% = 25%
Answer:
Dan = 68
bobbi = 62
Step-by-step explanation:
Let Bobbi's height = b
Let Dan's height = d
the following equations can be determined from the question
b + d = 130 eqn 1
3b - d = 118 eqn 2
Multiply eqn 1 by 3
3b + 3d = 390 eqn 3
Substract eqn 2 from 3. this gives
4d = 272
d = 68
Substitute for d in eqn 1
b + 68 = 130
b = 62
