Answer:

1/4.

Step-by-step explanation:

If the bag contains a total of 8 balls, then the chance of picking 2 yellow balls from a total of 8 balls is given by 2/8, simplified, this is 1/4.

This is how you simplify:

1. Write the fraction.

$\frac{2}{8}$

2. Find a number that can divide both the numerator and the denominator. A number could be 2, therefore, divide both the numerator and the denominator by this number.

$\frac{2/2}{8/2} =\frac{1}{4}$

Final answer: $\frac{1}{4}$

What is the product of and (6+5i) and (3-7i) ? -17-27i -17+27i 53+27i 53-27i

USPshnik [31]

We are going to make the product step by step.
We have:
(6 + 5i) * (3-7i)
Multiplying:
((6) * (3)) + ((6) * (- 7i)) + ((5i) * (3)) + ((5i) * (- 7i))
Rewriting:
18 - 42i + 15i - 35i ^ 2
18 - 42i + 15i - 35 * (- 1)
18 - 42i + 15i + 35
53 - 27i
Answer:
the product of and (6 + 5i) and (3-7i) is:
53-27i
