U can simplify each number to the bottom. Then determine which number pair u can take out. Put those outside of the square too sign. Numbers with out a pair must stay inside the square room
Answer: 0.001
Step-by-step explanation:
Given
The lock has 3 dials, each with the number 0 through 9.
The first place can be filled in 10 ways and the probability of selecting number '4' out of the 10 is
Similarly for selecting '3' and '9' is also
Therefore the probability of getting a combination of 4-3-9 is
Answer:
Perfect positive association is the answer :)
Answer:
x = 101/20, y = 1/4
Step-by-step explanation:
Solve the following system:
{-y + 5 x = 25 | (equation 1)
3 y + 5 x - 1 = 25 | (equation 2)
Express the system in standard form:
{5 x - y = 25 | (equation 1)
5 x + 3 y = 26 | (equation 2)
Subtract equation 1 from equation 2:
{5 x - y = 25 | (equation 1)
0 x+4 y = 1 | (equation 2)
Divide equation 2 by 4:
{5 x - y = 25 | (equation 1)
0 x+y = 1/4 | (equation 2)
Add equation 2 to equation 1:
{5 x+0 y = 101/4 | (equation 1)
0 x+y = 1/4 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 101/20 | (equation 1)
0 x+y = 1/4 | (equation 2)
Collect results:
Answer: {x = 101/20, y = 1/4
