Answer:

Step-by-step explanation:
Let's bring the line in the classical
form

At this point we have the two values
for the slope and
for the intercept
Answer:
£480
Step-by-step explanation:
x = the original price of a computer
£x = 100% of the original price
The price of a computer was decreased by 30% to £336.
This means:
£336 = 100% - 30%
£336 = 70% of the original price
From this, we will find 1% of the original price.
£336 ÷ 70 = 1%
£4.8 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£4.8 × 100 = 100%
£480 = 100%
Therefore, the original price of a computer = £480
Answer:
a) it is not a binomial, it is hypergeometric distribution.
Step-by-step explanation:
a) Four hundred different voters in a region with two major political parties, A and B, are randomly selected from the population of 3000 registered voters.
it is not a binomial because the probability of succes changes between one trial and another one, so the trials are not independent.
Answer:
In the year 2010, the population of the city was 175,000
Step-by-step explanation:
If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
What are the statements? Cannot answer without them.
