"<span>The interior angles of both a regular and irregular pentagon have a sum of 540o. "
</span>Regardless of it's shape if it's a polygon with 5 sides (whether is it regular or not) the interior angles with have the sum of 540 degrees.
I’m not sure let me figure it out real quick
Answer:
Susan has more books than Michael.
Step-by-step explanation:
If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60
40 + 8 = 48
60 is more than 48, so Susan has more books than Michael
Answer:
8.3 cm
Step-by-step explanation:
So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.
Perimeter (P) = s+s+s+s+s (sides)
P: 41.5 cm ÷ 5 =
8.3 cm
We know this is correct because:
8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5
Hope this helps!
Answer:
68% of an investment earning a return between 6 percent and 24 percent.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 15
Standard deviation = 9
How likely is it to earn a return between 6 percent and 24 percent?
6 = 15 - 1*9
6 is one standard deviation below the mean
24 = 15 + 1*9
24 is one standard deviation above the mean
By the empirical rule, there is a 68% of an investment earning a return between 6 percent and 24 percent.
