Answer:5
Step-by-step explanation:
Solve the inequality. Graph the solution.
−8≤z+6.4
The solution is
So if you plug -3 in for x it should become y=6•-3+8 and simplifies down to -18+8=-10 so y=-10
4х - 16 = 6 * (3 + х)
4х - 16 = 18 + 6х
4х - 6х = 18 + 16
- 2х = 34
х = 34 : (- 2)
х = - 17
-------------------------------------------
4 * (- 17) - 16 = 6 * (3 + (- 17))
- 68 - 16 = 6 * (- 14)
- 84 = - 84
Answer:
The mean aptitude score is 3.14.
Step-by-step explanation:
The given frequency table is
Aptitude Score : 0 1 2 3 4 5
Frequency : 1 2 2 2 3 4

First find .
0 1 0
1 2 2
2 2 4
3 2 6
4 3 12
5 4 20
Sum = 14 44
Substitute in the above formula.
Therefore, the mean aptitude score is 3.14.
