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
Answer:
I got -y^2 - 9y -4 (I hope it helps)
Step-by-step explanation:
4y^2 - 5y^2= -y^2
7-11= -4
-6y + -3y= -9y
-y^2 -9y -4
Answer: 2 + √10 , 2 − √10
Step-by-step explanation:
-5x(x-4) = -30
divide by -5
x(x - 4) = -30
distribute the x
x^2 - 4x = 6
move the 6 to the left to have the equation equal zero
x^2 - 4x - 6 = 0
plug into the quadratic formula & solve
x
= 2 + √10 , 2 − √10
- Let the smaller number be x and the bigger number be y.
- Therefore, 3x = 2y
- Therefore, the smaller number = 30 - 18 = 12
