The experimental probability is what you actually rolled
24/60 = 2/5 = 40%
The theoretical probability is what we expect to happen
=number of even numbers / total number of numbers
3/6 = 1/2 = 50%
Answer:
2-7i is the correct option.
Step-by-step explanation:
We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:
2+7i
And the conjugate means in the complex number is opposite sign of imaginary part that is in general:
a+ib will have conjugate a-ib
So, the conjugate of 2+7i is 2-7i
Hence, Option d is correct.
Answer:
1) -9
2) 10
3) -2
4) 9
Step-by-step explanation:
Answer:
16a^2 + 4a or 4a(4a+1)
Step-by-step explanation:
Use the distributive property (or FOIL).
First, the 3a2 becomes 6a.
6a x 4a = 24a^2
4a x -2a = 8a^2
4a x 1 = 4a
Simplify.
24a^2 - 8a^2 + 4a
=16a^2 + 4a
Other options:
=16a^2 + 4a
=4a(4a+1)
Hope this helped.
