Factorising quadratic expressions

Multiply these brackets to remind yourself how to factorise.

( x + 2 ) ( x + 5 ) = x2 + 7x + 10( x + 2 ) ( x + 3 ) = x2 + 5x + 6( x - 3 ) ( x - 5 ) = x 2 - 8x + 15( x + 6 ) ( x - 5 ) = x2 + x - 30( x - 6 ) ( x + 5 ) = x2 - x - 30

From the available information, we can only find the range of the data set.

The range is the highest value minus the least value.

This implies that, the range is $89-20=69$

fiasKO [112]

Answer:

The store can be 90% confident that the interval from 0.293 to 0.355 captures the proportion of all customers of this store who have moved in the past 5 years.

Step-by-step explanation:

The confidence interval provides a range of values (lower and upper bound) based on a certain confidence level at which the true proportion or mean value of a given sample mean or proportion exists. In the scenario above, the confidence level is 90% and the confidence interval is 0.293 to 0.355. Hence, we can be 90% confident that the true proportion of all customers of the store who have moved within the last five years exists within this interval.
