Option 1 is the correct answer
Answer:
900 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon can be found by
(n-2)*180 where n is the number of sides
This figure has 7 sides
(7-2)*180
5*180
900
The average mean is equal to the sum of numbers divided by the total numbers, which means that the mean of 230 with 80 numbers gives that the sum is 230*80 = 18400, if you apply the formula described in the beginning. Since 4 numbers are known and are<span> 145,156,210, and 255, their sum is </span>766. The sum of the list is equal to the sum of the numbers without the sum of 4 known numbers, so it's equal to 18400 - 766 = 17634, from which we can see that the Mean = (Sum Of List)/(80 - 4)
= 17634/76
= 232.02
Which ones? Or all of them need to be answered ?
Answer:
22/3 yards, roughly 7.33 yards.
Step-by-step explanation:
We know that there is 3 feet in 1 yard.
Given 22 feet, we divide by 3 to find the amount of yards, thus changing the unit.
The exact amount of yards is just 22/3, which you can estimate to 7.33 yds.
