Answer:
cos K = 12/13
Step-by-step explanation:
cos theta = opposite side/ hypotenuse for a right triangle
cos K = 12/13
Answer:
1/45
Step-by-step explanation:
I assume there are 10 marbles total, 2 of which are yellow.
The probability the first marble is yellow is 2/10.
There's now one less marble, so the probability that the second marble is yellow is 1/9.
The total probability is (2/10) (1/9) = 1/45.
1 + 0.09 = 1.09
90 * 1.09 = 98.1
The original price of the in-line skates was $98.1
