<span>Step 1. Let x be the number and 1/x be its reciprocal.
Step 2. Then, since the sum of a number and its reciprocal is 25/12.
Step 3. Multiply 12x to both sides of the equation to get rid of the denominators.
Step 4. Subtract 25x to put the equation in quadratic form

Answer:
Step-by-step explanation:
The parameter of interest summarizes the population of interest as a whole. It also gives the value that summarizes the entire population
In this case study the parameter of interest is all children in both two parents and single parent homes living in school districts.
410.5yd

, The proper formula to find the volume is,

.
A percentage is a portion out of 100, and because it is a portion of a whole it can be written as a fraction of an amount (in this case a fraction of 100). You can also rewrite this as a decimal because a fraction is essentially the same thing as a division problem and when you divide a number by 100 you usually get a decimal (if the numerator is smaller than 100 that is), and also because decimals are similar to fractions because they represent parts a whole unit for instance the percentage 72% is equivalent to the fraction 72/100 which is the same as 72 divided by 100 which is the same as the decimal 0.72.
Sorry for the long explanation but I hope this helped!
