<h2>Solution</h2>
A <em>conditional relative frequency table</em> shows the relative frequencies determined upon a row or column.
There are two types of relative conditional frequency table: 1) row conditional relative frequency, and 2) column conditional relative frequency.
When you divide the joint frequency by the marginal frequency of the column total you have the row conditional frequency table. When you dividethe joint frequency by the row total you have the colum conditional frequency table.
In a row conditional relative frequency each total of the right hand column equals 1. This is the case of the second table.
In a column conditional relative frequency each total of the bottom row equals 1. This is not happening with any of the shown tables.
Hence, only the second table could be a conditional relative frequency table.
Answer:
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2 +2d-8=0
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2

Step-by-step explanation:
h(+-)16+power 2+128+
The smallest value is $0.25 (a quarter) because you can use two quarters and a half dollar. Only one of them can't be a half dollar, but the other two can be.
