421 because 400 plus 15 plus 6 is 421
Okay, for variable B you have the data points:
1, 2, 3, 5, 6, 6, 7, 7, 10, and 10.
What you need to do to find the mean (or average) is add all the data up and divide by how many pieces of data you had. So, the sum of all the points is 57. There are 10 points overall.
57/10 is 5.7
Your average for variable B is 5.7
Answer:
1) g ≥ 17
2) g > -10
3) g > -1
Step-by-step explanation:
1) 7 (g-19) ≥ -14 divide both sides by 7
g - 19 ≥ -2 add 19 to both sides
∴ g ≥ 17
=======================================
2) 3(7g+17) > -19 + 14g
21g + 51 > -19 + 14g
21g - 14g> -19 - 51
7g > -70
g > -10
========================================
6(-6g+6) > -2(19g-17)
-36g + 36 > -38g + 34
-36g + 38g > 34 - 36
2g > -2
g > -1
========================================
Y=(x-4)/2x-11x+28
y=(x/2x)-(4/2x)-11x+28
y=0.5x-2x-11x-28
1. subtract like terms
2. add 28 on both sides
3. so on and so forth...
