Response:
Detailed explanation:
Probability for an event is calculated as the ratio of the size of the event space compared to that of the sample space.
The sample space encompasses all possible outcomes.
Event space represents the number of favorable outcomes for the event in question.
Thus
Let
x ------> size of event space
y ----- → size of sample space
so

I recently completed this question!
Here are the answers:
1) same side interior angles
2) (3x+4)+(2x+11) = 180
3) 77
Answer:
First, we must calculate the slope
m=Y2-Y1/X2-X1
= 9 - (-6) / 12 - (-8)
= 15/20
= 3/4
Therefore, the equation with the slope of 3/4 is Y=3/4x
Option D is indeed correct, as it ensures that the post's point is equidistant from the ground, maintaining a perpendicular angle at two points on the surface.
Answer with explanation:
Total number of children = x
Total chocolates shared = y
In total, the chocolates distributed to the children equals 5 times the number of children, or 5 x.
Chocolates received by adults equal 20.
Let the number of adults be z.
Expressing this situation as an equation:
y = 5 x + 20 z
⇒Number of adults = z
