Step-by-step explanation:
The two-point form of the equation of a line is:
We have:
x1 = 3
y1 = -2
x2 = 6
y2 = -8
Plug in all the values where they belong in the equation above.
Simplify.
This is the concept of algebra, we are required to find a number,x, such that 87 decreased by three times a number is great than one hundred and sixty-five.
Supposed the number is x, three times the number will be:
3*x=3x
thus;
87-3x≥165
-3x≥165-87
-3x≥78
dividing both sides by -3 we get:
(-3x)/(-3x)≥78/(-3)
x≤-26
This implies that the number is less than or equal to 26
Chance of a 2: 1/10. Chance of a 3: 1/10. These are disjoint events (they can’t happen at the same time) but we need the probability that either can happen. So 1/10+1/10=2/10=1/5.
This intuitively makes sense since there are 2 numbers out 10
6 and 16
