Answer:
3-2x+1
Step-by-step explanation:
If we indicate x the generic number we can write this expression
3-2x+1
when a sign of an operation is not expressed it means that the operation is multiplication
2x means 2*x
$97.2
120*.75 =90 (discounted price)
90*.08 = 7.2 (amount sales tax)
90 + 7.2= 97.2
The correct answer is D.14.
The interquartile range is the difference between the Upper Quartile and the Lower Quartile of a data set.
By arranging the numbers in the stem and leaf plot from lowest to highest value, you get an even set of data (31,33,35,41,43,46,48,49,49,50). By dividing the set into two, you get a lower half of your data (31,33,35,41,43) and an upper half (46,48,49,49,50). The lower quartile is the median or the midpoint of the lower half of your data while upper quartile is for the upper half. The lower quartiles is 35 and upper quartile is 49. The difference between the two is 14.
Answer:
None of the above ? （the equation should be y=12）
Step-by-step explanation:
the line parallel to line y=40-1=39 means it's a horizontal line. Which means it's y coordinate is also a constant. Since it pass through （2,12）,it means the constant of y is 12.
