<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2
Thus, the answer is "A"
Additionally, we can verify this using a square where the total angles add up to 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct

The accurate selections are: 1. For both families, the graph representing the connection between the number of pizzas (x) and the amount of slices (y) intersects at the origin (0, 0) and forms a straight line. 2. If the Wilson family orders 3 large pizzas from the same pizza shop as the Hernandez family, they will have a greater number of slices than the Hernandez family once the pizzas are sliced. The equations for the relationships between total slices (y) and pizzas ordered (x) are as follows: y = a × x, where 'a' indicates slices per pizza. For the Hernandez family, we have y = 24 when x = 3, resulting in a = 24/3 = 8 slices per pizza, producing the equation y = 8 × x. For the Wilson family, the relationship is represented by y = 10 × x. When both families’ equations are plotted, the result is straight-line graphs with a y-intercept of 0, meaning they pass through (0, 0). Thus, if the Wilsons order 3 large pizzas, they will have y = 10 × 3 = 30 slices, exceeding the Hernandez family's 24 slices.
Answer: (0.760, 0.820)
Step-by-step explanation:
Denote p as the proportion of adults in California who believe that "education and our schools" are among the foremost concerns in the state.
Given: 79% (actual results indicate 400 out of 506 surveyed) of adults in California consider "education and our schools" one of the main issues currently facing the state.
In other words, sample size: n= 506
Sample proportion: 
Critical value for a 90% confidence interval (Using z-value table):
Now, the confidence interval for the population proportion at 90% will be:
In other words, 
In summary, 
Thus, the 90% confidence interval for the population proportion= (0.760, 0.820)
Response:
C
