Answer:
Rodney sold 45,612 copies of his book and Beth sold 45,612 x one half copies of her book. Which statement compares the numbers of book copies sold? Beth sold half the number of book copies that Rodney sold.
Rodney sold half the number of book copies that Beth sold.
Beth sold twice the number of book copies that Rodney sold.
Rodney sold the same number of book copies that Beth sold.
Step-by-step explanation:
Complelment adds to 90
let's say the complement is B
A+B=90
4x+2+B=90
minus (4x+2) from both sides
B=88-4x
There are different levels of measurement that have been classified into four categories. It is important for the researcher to understand the different levels of measurement, as these levels of measurement play a part in determining the arithmetic and the statistical operations that are carried out on the data.
In ascending order of precision, the four different levels of measurement are:
<span>nominalordinalinterval<span>ratio</span></span>
Originally we have
length = x
width = x-2
since the width is 2 inches smaller than the length
now let's triple each dimension. Multiply the expressions by 3 to get
new length = 3*x
new width = 3*(x-2) = 3x-6
Now onto the area
area = (length)*(width)
area = (3x)*(3x-6)
area = 3x*3x-3x*6
area = 9x^2 - 18x
So the new larger rectangle has area of 9x^2-18x
