Answer/Step-by-step explanation:
a. Using two points on the line (0, 2) and (4, 12), find the gradient:
Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5
Gradient = 2.5
b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.
i.e. 2.5 litres per second
c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.
Answer:
A. 27
Step-by-step explanation:
21 x 3 = 63
9 x 3 = 27
Probabilty = 12×(1/12)^3=1/144
Answer:
b is wrong it is c

Step-by-step explanation:
The final interior angle is 127<span>°. Pentagons' interior angles add up to 540, so you add the ones you know together, subtract the big number from 540, and you have your answer. </span>
