Alla [95]
Ok...so u have 4 people sharing this plan...they each pay for their own data..however, the $ 90 flat rate is split between them equally.

How can a ratio's number can be changed without changing the ratio itself
eimsori [14]
<h2>Answer:</h2>

The ratio is a fraction that tells us how many times longer a thing is compared to another thing. In mathematics, we express a ratio as the relationship between two numbers, namely a \ and \ b, so the ratio can be written as:

r=\frac{a}{b}

If we can change this number without changing the ration we need to multiply  both the numerator and the denominator by the same number. For instance, if we have the following ratio:

r=\frac{2}{3}

We can multiply both the numerator and denominator, say, by 7. Then:

r=\frac{7\times 2}{7 \times 3}=\frac{14}{21}

As you can see, the ratio's number has changed but without changing the ratio itself because:

\frac{2}{3}=\frac{14}{21}

Given that India is the second most populous country in the world, with a population of over 1 billion people.

The pdf of household size say X in India varies from 1 to 8.

The distribution is shown as follows

X       1      2     3        4      5       6        7      8       Total

P  0.02  0.09  0.18  0.25  0.20  0.12  0.08  0.06    1.00

a) the probability that there are less than 5 members in a household in India

=P(X

=P(1 to 4) = 0.54

b.  the probability that there are 5 or more members in a typical household

in India

=P(X\geq 5) = P(5 to 8)\\\\= =0.46

c) the probability that the number of members in a typical household in India is strictly between 2 and 5

=P(2
