Answer:
Add
Step-by-step explanation:
When MULTIPLY exponents with same base, you Keep the base and + ADD the exponents.
8+9 = 17
7+8 = 15
6+7 = 13
5+6 = 11
4+5 = 9
3+4 = 7
2+3 = 5
1+2 = 3
0+1 = 1
These are the <span>combinations of consecutive integers with a sum less than 19</span>
It's a mistake to say that the area under the standard normal curve associated with a z score of 3 is 0. That area is actually slightly less than 1.
Using a old but good calculator with statistical functions:
normalcdf(-100, +3) = 0.999
(x - 4)(x + 2i)(x - 2i) = 0
x(x^2 + 4) - 4(x^2 + 4) = 0
x^3 + 4x - 4x^2 - 16 = 0
x^3 - 4x^2 + 4x - 16 = 0
