Plz last questionsimplify the given expression below: 2 divided by the quantity of 2 plus 5i 2 over 29 4 over 29 the quantity of 4 plus 10i, divided by 29 the quantity of 4 minus 10i, divided by 29

Step-by-step explanation:

2 divided by the quantity of 2 plus 5i

to divide we mutliply the fraction by the conjugate of denomiator

conjugate of 2+5i is 2-5i

(2+5i)(2-5i)= 4 +10i +10i - 25i^2

the value of i^2=-1

(2+5i)(2-5i)= 4 +10i +10i - 25i^2= 4 - 25(-1)= 29

c. A number relatively close to 100.

Step-by-step explanation:

Given

--- i.e. the cells

Required

Number of cells that contains less than or equal 0.2

Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution

So, to calculate the number (n) of these cells, we do the following computation

200 is closer to 100 than 500. Hence, (c) is correct
