Multiply first and last coefficients:
2*(-9) = -18
Find 2 factors which multiply to -18 and add up to 17:
18 and -1
Rewrite quadratic with 17y split up as' 18y - y', Then factor by grouping:
Answer:
0.48
Step-by-step explanation:
The range of a data set is the largest quantity subtracted by the smallest quantity. In this case 1.61 is the smallest. 2.09 is the largest. So we need to do 2.09-1.61 and get the range of 0.48! Stay safe!
13.8 is bigger being a positive number.
The last answer, because the class is being divided into four groups. So the class number is not known, thus it is represented by “w” and divided by four.
Well 3.20 is 2 tenths of 1 and .02 is 2 hundredths of one so its >
