7. a. Lin is using the diagram to prove the statement, “If a parallelogram has one right angle, it is a
rectangle." Given that EFGH is a parallelogram and angle HEF is a right angle, write a statement that will
help prove angle FGH is also a right angle.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

maybe i can

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
