Answer:

Pop in 1990 = 81 million rats

Pop in 2005 = 127 million rats

Step-by-step explanation:

Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.

The rat population in 2005 is given by the formula when t = 15

This is: approximately 127 million rats.

A computer chip manufacturer made 270,000 chips last week. If 8% of them were defective, how many defective chips were made?

Alina [70]

Number of defective chips = 8% of 270,000

= $\frac{8}{100}$ x 270000

= 8 x 2700

= 21,600

Thus, 21,600 defective chips were made.

I hope this answer helps! If you have any doubts, feel free to ask!
