We are given with
95 pink rubber bands
90 brown rubber bands
The probability of selecting a pink rubber band is
P = 95 / (95 + 90) = 19/37
The probability of selecting a brown rubber band is
P = 90 / (95 + 90) = 18/37
Answer:
Im not sure if the numbers in the title were included, but the answer would be: 8.5, 9, 9.5, 10, 10, 10, 11.5, 12, 12, 70, 70, 72, 105.
Step-by-step explanation:
Quick answer: no you cannot.
Details:
The law of cosines relates between two adjacent sides and the included angle to calculate the third side (opposite to the included angle).
Any combinations of data giving 3 of the above-mentioned pieces of information will enable us to calculate the fourth. Otherwise, the sine rule is used to calculate some of the angles or sides before cosine rule can be used, if at all necessary.
Factor using the difference of squares.
a^2-b^2 = (a+b)(a-b)
100n^2-1
(10n+1)(10n-1)
Final answer: (10n+1)(10n-1)
