Given:
convex 41-gon
n = 41
Required:
Sum of interior angles.
Solution:
To solve for the sum of interior angles, we can use the formula:
Sum of interior angles = 180(n-2)°
Substituting,
Sum of interior angles = 180(41-2)°
Sum of interior angles = 7020°
Therefore, the sum of the measures of the interior angle of a convex 41-gon is 7020°.
Answer:
Option D
Step-by-step explanation:
A reporter collects a random sample of 50 runners from all the runners who finished the Cherry Blossom Ten Mile Run in 2009 and constructs a 99% confidence interval for the true mean finish time to be (86.05, 99.38) minutes.
Assuming the reporter performed the calculations correctly, which of the following statements are appropriate interpretations of this confidence interval?
We can expect that 99% of confidence intervals created using the same method the reporter used will contain the true mean run time for runners of this race.

Answer:
-1
Step-by-step explanation:
Because in this equation the -1 doesn't have any variables (x,g,etc.) it makes it the y intercept, therefore your y intercept is y= -1
Answer:
a) -4
b) +343
Step-by-step explanation:
a) 10 shares - loss $40
1 share --- ?
? = 40 / 10 = 4 decrease
b) each week 7 members increase for 49 weeks
so total increase = 7 * 49 = 343
