A bicycle lock requires a two-digit code of numbers 1 through 9, and any digit may be used only once. Which
expression would determine the probability that both digits are even?
OP(both even) = 6 Pr>(zP1)
8P2
O P(both even) = 6C;)(3G)
92
OP(both even) = ($Py) GyPj).
9P2
OP(both even) = (561)64C;)
9C2

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
