Answer:
Two hundred would be appropriate for a random sample.
Answer:
You asked to solve questions 3 and 5
<h3>#3</h3>
Since CD = EF,
- 9x - 1 = 41 - 5x
- 9x + 5x = 41 + 2
- 14x = 42
- x = 3
<h3>#5</h3>
MN = NP as their perpendicular bisectors are of same length.
- 9x - 43 = 5x + 33
- 9x - 5x = 33 + 43
- 4x = 76
- x = 19
- mMP = 360 - (mMN + mNP)
- mMP = 360 - (9*19 - 43 + 5*19 + 33)
- mMP = 104
Answer:
True
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
I think it’s D. 156 degrees
