Answer:
The prediction for the number of transistor per IC in 1992 is of 4,194,304,000
Step-by-step explanation:
Moore's law:
Moore's law states that the number of transistors per IC doubles every year.
Format of the function:
Following Moore's law, t years after our initial estimative, the number of transistors per IC will be given by:

In which N(0) is the initial estimate.
The number of transistors per IC in 1972 seems to be about 4,000 (a rough estimate by eye).
This means that 
So

What would you predict the number of transistors per IC to be 20 years later, in 1992?
This is N(20). So

The prediction for the number of transistor per IC in 1992 is of 4,194,304,000
55 kilograms of aluminum and 345 kilograms of the other metals
Answer: 13 pairs
Step-by-step explanation:
Given
Jessica owns 18 pairs of shoes
Lindsay has 72% as many as Jessica
So, the number of pairs Lindsay owns

The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.
According to my TI-83 calculator,
normalcdf(110,120, 100, 15) = 0.16, or 16%.
Answer:
193 square inches to the nearest WHOLE NUMBER
Step-by-step explanation:
Given:
- perimeter : 53 inches
- apothem: 7.3 inches
As we know that, the formular to find the area of the regular pentagon is:
A = 1/2 × apothem × perimeter
In this situation, the area is:
A = 1/2 × 7.3 × 53
= 193.45
= 193 square inches to the nearest WHOLE NUMBER
