The probability that he lost less than 19 pounds is 7 / 9.
According to statement
The weight loss by individual is 12 Pounds
So, by uniform distribution probability
P(c ≤ x ≤ d) = (d - c) / (b - a)
Substitute the values in it then
P(12 ≤ x ≤ 19) = (19 - 12) / (20 - 11)
P(12 ≤ x ≤ 19) = 7 / 9
So, the probability that he lost less than 19 pounds is 7 / 9.

Step-by-step explanation:
Rounding means making a number simpler but keeping its value close to what it was. Visual image below of showing different places to round. Given to make rounding's more clear and easier for you.
6(7+5) + 3 =
42 + 30 + 3 = <<<< This one is the equivalent expression
If you wanted to continue and solve...
72 + 3 =
75

here there is 1/3 chance
if 2 coin it is 2/6 that is 1/3 which is 0.33
Answer:
Step-by-step explanation:
Answer: x = 7 and y = -2
Step-by-step explanation:
2x +3y = 8 ----------------(1)
x-y = 9 ----------------------(2)
multiply (2) by 2
2x-2y = 18--------------------(3)
subtract (2) from (3)
-5y = 10
Divide bothside by -5
y = -2
Similarly, multiply (2) by 3
3x-3y = 27-----------------------(4)
add (1) and (4) together
5x = 35
Divide bothside by 5
x= 7
Therefore, x =7 and y= -2
