Answer:
Hey stu132057, your the MAD for the data set given is
Step-by-step explanation:
Step 1: Find the mean of the data: (14+13+16+12+17+21+26)/7 = 17
Step 2: Find the difference between each data and mean:Difference between 14 and 17 is 3
<u>Difference between 13 and 17 is 4</u>
<u>Difference between 16 and 17 is 1</u>
<u>Difference between 12 and 17 is 5</u>
<u>Difference between 17 and 17 is 0</u>
<u>Difference between 21 and 17 is 4</u>
<u>Difference between 26 and 17 is 9</u>
Step 3: Add all the differences: 3+4+1+5+0+4+9 = 26
Step 4: Divide it by the number of data:26/7 = 3.7
So, the MAD = 3.7

Answer: the sum of p and q
Step-by-step explanation:
Answer:
0 real roots or 2 complex roots
Step-by-step explanation:
Discriminant: b² - 4ac
If d > 0, then there are 2 real zeros
If d = 0, then there is 1 real zero
If d < 0, then there are 0 real zeros and 2 complex/imaginary zeros
Simply substitute <em>a </em>= 1, <em>b</em> = -5, and <em>c</em> = 40
Our d should equal -135, showing us we have 0 real roots and 2 complex ones.
