B. Jm tosses a biased coin 50 times, and it lands on heads 40 times. If he tosses the coin 22 more times, which of these is the most reasonable prediction of the difference between the number of heads and tails he will get? 1 6 12 17

It is most reasonable to say he will get heads more than tails, because in the 50 times he tossed the coin it landed on heads 40 times  and it landed on tails only 10 times which means  the chance of getting heads again is 60% higher than the chance of getting tails.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

is only a line? i think so
