Answer:
a)x1 = -2, x2= 2
b) x= -1
Step-by-step explanation:
Answer:
the quantity obtained by dividing the number one by a given quantity.
Answer:
Options B and D are true.
Step-by-step explanation:
See the diagram attached.
Line a and b are parallel and line c is not parallel to them.
There is a transverse line and this line forms the angles 1 to 12.
Now, option A gives ∠ 8 + ∠ 10 = 180° which can not be true as line c is not parallel to line b.
Option B gives ∠4 + ∠ 6 = 180° which is true because line a is parallel to line b and ∠ 4 and ∠ 6 are interior supplementary angles.
Option C gives ∠ 1 + ∠ 11 = 180° which can not be true as line c is not parallel to line a.
Option D gives ∠3 + ∠ 5 = 180° which is true because line a is parallel to line b and ∠ 3 and ∠ 5 are interior supplementary angles.
Therefore, options B and D are true. (Answer)
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
