When you subtract 
you get a common difference, the same goes for the other values: when you subtract the previous term from the next, you get a common difference of positive 3.8
Answer:
3x³ + 23x² + 63x + 55
Step-by-step explanation:
Given
(3x + 5)(x² + 6x + 11)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis
= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms
= 3x³ + 23x² + 63x + 55
The midpoint is the middle, which is the average. So you would do 6.9+1.7 which is 8.6 then divide it by 2, giving you the answer 4.3.
4.3 inches of rainfall is the midpoint
Answer:
4.
- this shows that the height of 13 year old females in one class is less variable than the other class.
- this means that the height of students in class with range 6 may vary from person to person while that in class with range 3 maybe clustered around one another.
- we're expected to see students of almost same height in class ,with range 3, more than the students in class with range 6.
5.
arranging the values in ascending order
2, 2, 4, 4, 4, 5, 6, 6, 6, 8, 8, 9
median = 1/ 2 [ n/2th term +{ (n/2)+ 1 }th term ]
for n is even
= 1/ 2 [ 6th + 7th term]
= 1/ 2 [5 + 6]
= 5.5
mode = value with highest frequency or the value that appears most frequently In a given set of data.
mode =4, 6
because both 4and 6 appear 3 times in the given set of data which is the highest frequency.
