How do you simplify #(-3 - 2i)(-3 + 3i)#?

1 answer:

7 0

So, ( -3 - 2i )( -3 + 3i ) = 9 - 9i +6i - 6i^2 = 9 - 3i - 6·(-1) = 9 + 6 - 3i = 15 - 3i;
We have / 15 +(- 3)i / = 15.29; $\sqrt{ 15^{2} + (-3)^{2} } = \sqrt{225 + 9} = \sqrt{234} =$

On a lunch counter, there are 3 oranges, 5 apples, and 2 bananas. If 3 pieces of fruit are selected, find the probability that 1

muminat

Answer:

$Probability = \frac{1}{24}$

Step-by-step explanation:

Given

$Oranges = 3$

$Apples = 5$

$Banana = 2$

$Total = 10$

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

$Probability = P(Orange) * P(Apple) * P(Banana)$

$Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}$

The difference in the numerator is as a result of picking the fruit without replacement

$Probability = \frac{30}{720}$

$Probability = \frac{1}{24}$
