Answer:
P(milk) = 7/18
P(not milk) = 11/18
Step-by-step explanation:
The bag contains 7 milk and 11 dark chocolates. That means that there are a total of; 7 + 11 = 18 sweets in the bag.
So, when a sweet is selected at random, probability that the sweet is milk is;
P(milk) = number of milk sweets/total number of sweets = 7/18
Probability it is not milk is;
P(not milk) = number that's not milk/total number of sweets = 11/18
All you have to do is multiply them all.
3*3*4*2=72

Answer:
Step-by-step explanation:
m∠ABC + m∠BAC + m∠ACB = 180°
a + 2a + 6a = 180°
9a = 180°
a = 20°
m∠ABC = 20°
m∠BAC = 2 × 20° = 40°
m∠ACB = 6 × 20° = 120°
Answer:
The roots are 0, 3 and 4.
Step-by-step explanation:
x^3-7x^2-12x = 0 Take out x:
x(x^2 - 7x - 12) = 0 Factor the expression in the brackets:
x(x - 3)(x - 4) = 0
x = 0 or x - 3 = 0 or x - 4 = 0, so
The roots are 0, 3 and 4.
