Answer:
Step-by-step explanation:
Mass (m kg) frequency mass (m kg) c.f.
0 < m ≤ 0.1 4 m ≤ 0.1 4
0.1 < m ≤ 0.2 6 m ≤ 0.2 10
0.2 < m ≤ 0.5 58 m ≤ 0.5 68
0.5 < m ≤ 0.8 28 m ≤ 0.8 96
0.8 < m ≤ 1.0 4 m ≤ 1.0 100
Total number of parcels surveyed = cumulative frequency = 100
For this question you can just divide the both sides by -7 so you gonna have :
-7b/-7 = -42/-7 ⇒ b = 6 :)))
i hope this is helpful
have a nice day
rhombuses have all of the properties ofparallelograms<span> along with a few others. Let's look at these properties. (1) Consecutive sides of a rhombus are congruent. (2) The </span>diagonals<span> of a </span>rhombus bisect pairs<span> of opposite angles]</span>
