Step-by-step explanation:
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
The Pythagorean theorem states that a^2 + b^2 = c^2, where a and b are sides not opposite to the right angle, shown as a square. C represents the hypotenuse, or side opposite of the right angle
We see that a = 14 (it can also be b; both can be plugged in as both are adjacent and not opposite of the right angle)
c = 19; hypotenuse is opposite of right angle
14^2 + b^2 = 19^2
196 + b^2 = 361
b^2 = 361 - 196
b^2 = 165
b = square root of 165
b = 12.845
x = 12.845
If the three sets of corresponding sides of two triangles are in proportion, the triangles are similar. SAS for similar triangles is NOT the same theorem as we used for congruent triangles.
