If we take the graph with x as number of years and y as amount of dollars in it as mentioned in the equation;
gradient of the graph/ slope (m) = Change in y / change in x
so if we take a certain portion of the graph
x is the number of years, since we know the growth for one year,
lets take change in x as 1 year
y is amount of dollars, the change in amount of dollars for one year is 28
therefore change in y is 28
m(slope) = 28(change in y) / 1 (change in x)
= 28
The variance of the binomial distribution of the number of households with landline service is 2.
<h3>What is the binomial probability distribution?</h3>
It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The variance of the distribution is given by:
V(X) = np(1 - p)
In this problem, the parameters are given as follows:
n = 8, p = 0.504.
Hence the variance is given by:
V(X) = 8 x 0.504 x 0.496 = 2.

It is 0.0411764706 when divided with a calculator. In a scientific notation it would be 4.11764706 x 10^(-2).
Considering the sequences given, the first number that appears in both sequences is given by: 45.
<h3>What numbers appear in the first sequence?</h3>
The rule is multiply by 3 starting from 5, hence the numbers are:
(5, 15, 45, 135, ...).
<h3>What numbers appear in the second sequence?</h3>
The rule is add 9 starting from 18, hence the numbers are:
(18, 27, 36, 45, ...).
45 is the first number that appeared in both sequences.

There are seven SI base
units which are used in science, every unit has its own property or use:
Meter (length)
Kilogram (mass)
Second (time)
Kelvin (temperature)
Mole (amount of substance)
Ampere (electrical unit) and
Candela (luminous intensity)
<span>The SI unit of
measure for length (meter) would be most appropriate when we are measuring the
distance between two places or when we are taking measurement of something.</span>
