Equation if the line for the graph is
y = -2x+1
10/23=15/m
(15x23)/10
343/10
34.3
so....
10 laps in 23 minutes
=
15 laps in 34.3 minutes
Answer:
20°
Step-by-step explanation:
The sum of angles in a ∆ = 180°
Therefore, 
Use this expression to find the value of x, then find the measure of angle A.
Subtract 20 from both sides
Divide both sides by 20
Find measure of angle A.
Angle A is given as 
Plug in the value of x and solve
Answer:
28.57%
Step-by-step explanation:
Answer: 2/7 in terms of percentage is written as 28.57% approximately.
The probabilities are:
- P(red) = 5/24
- P(orange) = 0
- P(blue) = 1/3
- P(not green)= 17/24
- P(green or black) = 11/24
- P(not yellow) = 1.

How to find the probabilities?</h3>
The probability of getting a particular color of marble, is given by the quotient between the number of marbles of that color and the total number of marbles.
Here we have:
- 5 red marbles.
- 7 green marbles.
- 4 black marbles.
- 8 blue marbles.
So the total number is 5 + 7 + 4 + 8 = 24.
Then:
- P(red) = 5/24
- P(orange) = 0/24 = 0 (because there are 0 orange marbles).
- P(blue) = 8/24 = 1/3
- P(not green) = (24 - 7)/24 = 17/24
- P(green or black) = (4 + 7)/24 = 11/24
- P(not yellow) = 24/24 = 1 (because there aren't yellow marbles).
