Using secant rule, the value of variable x in the diagram is 10.
<h3>What is a secant?</h3>
A secant is a line that intersect a circle in two points.
Therefore, the following rule guides a secant.
(x + 32)32 = (20 + 28)28
Hence,
32x + 1024 = (48)28
32x + 1024 = 1344
32x = 1344 - 1024
32x = 320
divide both sides by 32
32x / 32 = 320 / 32
x = 10

#SPJ1
5 red, 3 yellow, and 2 blue....for a total of 10 marbles
P(first one being blue) = 2/10 which reduces to 1/5
not replaced
P(second one is blue) = 1/9...because u already pick a blue, meaning there is only 1 left, and there is one less marble, so there is a total of 9 marbles.
P(both events happening) = 1/5 * 1/9 = 1/45 <==

The graph of the equations was plotted using geogebra graphing and attached.
Let x represent the hours weightlifting and y represent the hours doing cardio exercises.
Since he spend a maximum of 20 hours, hence:
x + y ≤ 20 (1)
Also, he spends at least 8 of those hours weightlifting, hence:
x ≥ 8 (2)
He wants to spend no more than 15 hours doing cardio exercises, this is:
y ≤ 15 (3)
