Javier read a report that said the probability that a randomly selected
American is left-handed is 14%. He was curious how many left-handed
students to expect in a class of 30 students. He simulated 100 classes of
30 students where each student selected had a 0.14 probability of being
left-handed. Javier counted how many left-handed students were in each
simulated class. Here are his results. Use his results to estimate the
probability that there are 7 or more left-handed students in a class of 30
students.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

step-by-step explanation:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
