solution:
The variable is discrete because it is countable.
The number5 of lightning strikes in a city in one year is countable value.
So, it is discrete
Answer:
Step-by-step explanation:
We have been given that the Rumpart family is building a new room onto their house. The width of the new room will be 16 feet.
The length of the room will be 4% greater than the width. This means that length of new room will be 16 feet plus 4% of 16.
Therefore, the expression 
represents the length of new room and the length of new room is 16.64 feet.
Since we know that area of a rectangular shape is width times length.
Therefore, the area of the new room will be 266.24 square feet.

n = 6
Answer:
100,000
Step-by-step explanation:
70,000 people = 70% of the population.
Divide 70,000 by 70 to get the number of population per 1%:
70000 ÷ 70 = 1000
Therefore, 1000 people represent 1% of the population.
To calculate 100% of the population, multiply the number of people representing 1% by 100:
1000 x 100 = 100,000
Therefore, the population of the town = 100,000
We can set up an equation.
.05 * 2^(n-1)
n being the nth term in the sequence
Plug in and solve.
.05 * 2^(20-1)
.05 * 2^19
.05 * 524, 288
The 20th term would be 262, 144.
