The probability of matching the second one correctly is 1/2 .
Then there's only one baby-pic left, so ...
The probability of matching the third one correctly is 1 .
So the probability of matching all three correctly is
(1/3) x (1/2) x (1) = 1/6 = (16 and 2/3) percent .
Answer:
AB = 10.83 cm
Step-by-step explanation:
From ΔABC,
m∠B = 90°
By applying sine rule in the given triangle,
sinθ = 
sin(37°) = 
AB = AC(sin37°)
AB = 18×(0.060182)
= 10.833
≈ 10.83 cm
Therefore, AB = 10.83 cm is the answer.
Answer:
The solution is (0, 3/4)
Step-by-step explanation:
Please copy and share the instructions. Here they are: Solve the following system of linear equations.
Both of the equations can be reduced (simplified):
2x+8y = 6 => x + 4y = 3
15x + 20y = 15 => 3x + 4y = 3
Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining
-x - 4y = -3
Add the second 3x + 4y = 3
equation to the
first.
We get: 2x = 0.
Thus, x = 0. Substituting 0 for x in the 1st original equation yields:
2(0) + 8y = 6. Then y = 6/8, or y = 3/4.
The solution is (0, 3/4).
