Let x represent the answer.
7 + x = (43+x) / 3
3(7+x) = 43+x
21+3x = 43+x
2x = 22
x = 11
The answer is 11
The correct answer would be B, or the second option.
In a function like this, the y-intercept, or the term without a variable, can be always be interpreted as a sort of starting amount, or a base amount.
Because we're given 5x + 20, we know 20 will be the base, or starting value, while 5 is the amount being added per value of x, which is equal to weeks.
Thus, the correct answer is B.
Total people = male + female = 82+18+94 +46= 240
People that do not exercise and is male: 18
To find the probability divide the number of people that do not exercise and are male, by the total number of people.
18/240 = 0.075
P = 0.075
