The multiplication of the expressions 2i and (4 – 5i) is 10 + 8i. Then the correct option is D.

<h3>What is multiplication?</h3>

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expressions are 2i and (4 – 5i).

Then the product of the expression will be given as

2i (4 – 5i)

8i – 10i²

And we know that i² = -1

Then we have

8i – 10 (–1)

10 + 8i

A spinner has three unusual sections: red, yellow, and blue.. The table shows the results of Nolan’s spins. Find the probability
Anika [276]

Answers:

  • Red = 1/3
  • Yellow = 7/15
  • Blue = 1/5

====================================================

Explanation:

Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.

  • Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3
  • Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15
  • Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5
