Answer:
1. 4x ≤ 25
⇒ x ≤ 6.25
2. x + 4 < 25
⇒ x < 21
3. x + 4 ≥ 25
⇒ x ≥ 21
4. 4 + x ≤ 25
⇒ x ≤ 21
Step-by-step explanation:
1. 4x ≤ 25
⇒ x ≤ 6.25
2. x + 4 < 25
⇒ x < 21
3. x + 4 ≥ 25
⇒ x ≥ 21
4. 4 + x ≤ 25
⇒ x ≤ 21

Step-by-step explanation:
Answer:
4.78125
Step-by-step explanation:
Step 1
Find the mean
Mean = Sum of Terms/Number of Terms
Mean = 7+5+ 16+20+ 17+ 9+ 18+ 15/8
= 107/8
= 13.375
Step 2
Find the Mean Absolute Deviation
Mean Absolute Deviation formula = |x - Mean|/n
Mean Absolute Deviation =[ |7 - 13.375| +| 5 -13.375|+ |16 - 13.375| + |20 - 13.375| +| 17 - 13.375| + |9 - 13.375 | +| 18 -13.375|+|15 - 13.375|] /8
Mean Absolute Deviation = 4.78125
Therefore, the Mean Absolute Deviation (M.A.D.) for these students = 4.78125
I believe x = 32 because it is an equalateral triangle meaning each angle is 60 degrees so the equasion is 2x-4=60.
