Answer:
1.Order the data from least to greatest.
2.Find the median.
3.Calculate the median of both the lower and upper half of the data.
4.The IQR is the difference between the upper and lower medians.
Step-by-step explanation:
Company A charges $75.50 and 14¢ per mile, then for x miles, Company A charges 75.5 + 0.14x dollars
Company B charges $30.50 and 9¢ per mile, then for x miles, Company B charges 30.5 + 0.09x dollars
Subtracting the second equation to the first one,
75.5 + 0.14x
-
30.5 + 0.09x
----------------------
45 + 0.05x
For x miles, Company A charges 45 + 0.05x dollars more than Company B.
Step-by-step explanation:
2x + 5 = 19; X = 7: Correct
2(7) + 5 = 19
14+5=19
3+x+2-x=16; x=3 : Incorrect
3+3+2-3=16
6+2-3=16
7-3=16
4=16
x+2/5=2; x = 8: incorrect
8+2/5=2
x= 8/5
6 = 2x -8; x = 7: correct
6 = 2(7) -8
6 = 14-8
14 =1/3x+5; x = 18: Incorrect
14 = 18/3+5
14 = 6+5
It took 9 hours of labor. 500 - 140 = 360...... 360 / 40 = 9.
Answer: 9.
