Line segment JM has endpoints with coordinates 0 and 25 on a number line. Points K and L are on segment JM. K has a coordinate of 5 and point L has a coordinate of 12. Find the probability that a point on JM is placed first on JL and a second point is not placed on KL.

Answer:
On a Number Line, if only whole numbers are marked
Points J, M, K, and L are marked, having coordinates 0, 25, 5, and 12.
Two points are again marked on the number line.
Probability,that a point on J M is placed first on J L
= There are 10 natural numbers in between J L and 12 natural numbers between L M.
So, Required Probability
Now, Probability that second point is not placed on KL, it means that point is either is on J K or L M.
There are 4 natural number between 0 and 5 and 12 natural number between L and M.
Probability of marking second point on J M is
Probability of marking two points on the number line, with given condition is
If you consider ,points on the number line which are real numbers, then we can't find the required Probability that is marking two points on the line segment.

Answer:
P = 62° Q = 28°
Step-by-step explanation:
Let x = measure of angle Q
then y = measure of angle P
Now x + y = 90 and 2x + 6 = y
Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.
3x + 6 = 90
3x = 84
x = 28
y = 2(28) + 6 = 56 + 6 = 62
Check: 28 + 62 = 90
Final answer:
To find the measures of complementary angles P and Q, we set up a system of equations based on the problem's information, solve for one variable, then substitute that variable's value into the other equation. After solving, we find that the measure of angle P is 62°, and the measure of angle Q is 28°.
Explanation:
Let's denote the measure of angle Q as 'q'. Therefore, the measure of angle P can be expressed as '2q + 6'. Now, we can set up two equations based on the information given:
- P + Q = 90°, or in terms of 'q', (2q + 6) + q = 90°
- P = 2Q + 6°, or in terms of 'q', (2q + 6) = 2q + 6
Solving the first equation gives us 3q + 6 = 90. Subtract 6 from each side of the equation to get 3q = 84. Divide each side by 3 to solve for 'q', and we find that q = 28°. Substituting q = 28° into equation 2, we find that P = 2*28 + 6 = 62°. So, angle P is 62° and angle Q is 28°.
