Population mean = (7+8+6+6+6+4+4+1+2+7+6+1+1+1+3+3+5+4+5+7) / 20 = 87/20 = 4.35 <==
sample mean = (4+5+7) / 3 = 16/3 = 5.33 <==
Answer:
multiply the value behind the other value
Step-by-step explanation:
3 x -12 = 48
-12 x 48 = -576
and so on
There is no function box.....
Answers:
15) x = 8, 
16) x = 9,
, 
17) x = 6,
, 
<u>Step-by-step explanation:</u>
15x³ - 119x² - 10x + 16 = 0

So, the possible rational roots are: +/- 
Use synthetic division with each one until you find a remainder of zero. I am not going to go through each one because it is too time consuming, however, the first one that works is x = 8
(x - 8)(15x² + x - 2)
Next, factor 15x² + x - 2 using any method
(x - 8)(3x - 1)(5x + 2)
Now, solve for x.
x = 8, x =
, x =
