Try this solution:
1. In order to built the line required in the condition it need to determine its equation.
Using the coordinates of point B (5;2), if to substitute them into the given equation: 2=-3*5+b, ⇒ b=17. It means, that the equation of the line required in the condition is y= -3x+17.
2. The graph is in the attachment; point (0;17) is the intersection point of Y-axis and the line.
Answer:
The answer is 45° and 55 °.
180° - 80° = 100°
Then add the two numbers from the ratio:
9 + 11 = 20
The divide 100 from 20.
100 ÷ 20 = 5
Then multiply it to two numbers from the ratio:
9 × 5 = 45 and 11 × 5 = 55
I hope it helps.
Answer:
100 bags
Step-by-step explanation:
S.E = σ/ √n
0.1 = 1 / √n
Square both sides
0.1² = 1² / n
0.01 = 1 / n
0.01n = 1
n = 1 / 0.01
n = 100
