Answer:
4320 degrees
Step-by-step explanation:
If interior angles are 3960 degrees then there are 24 sides. If polygon is regular, size of each exterior angle is 15 degrees.
A polygon has as many pairs of interior and exterior as number of its sides. Further each pair of exterior and interior add up to
180 degrees.
Sum of all the exterior angles of any polygon is
360 degrees
As sum of all the interior angles of the polygon is
3960 degrees
Sum of all pairs of exterior and interior angles is
3960 degrees + 360degrees = 4320 degrees
Answer:
-71/6
Step-by-step explanation:
[(1/4) -1 + (1/3) -2 - (1/2) -3 ] ÷ 5
[(3/12)-(12/12)+(4/12)-(24/12)-(6/12)-(36/12)] ÷ 5
[-71/12]/5
-71/60
Answer:
ab² - 9
Step-by-step explanation:
Given in the question an expression
(ab + 3)(ab - 3)
To product mentally we will use polynomial identity called
Difference of squares
<h3>a² - b² = (a+b)(a-b) </h3>
here a = ab
b = 3
(ab + 3)(ab - 3) = ab² - 3² = ab² - 9
Answer:
H-40
Step-by-step explanation:
Answer:
Stratified random sampling or proportional random sampling
Step-by-step explanation:
Firstly, the franchises are divided into smaller groups depending on shared attributes or characteristics.
After the grupation, the investor uses simple random sampling to identify some further proportion.
Since small grups obtained by the division are known as strata, the investitor is doing stratified random sampling.
