Javier read a report that said the probability that a randomly selected American is left-handed is 14 % 14%14, percent. He was curious how many left-handed students to expect in a class of 30 3030 students. He simulated 100 100100 classes of 30 3030 students where each student selected had a 0.14 0.140, point, 14 probability of being left-handed. Javier counted how many left-handed students were in each simulated class. Here are his results: 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9# of left-handed students Use his results to estimate the probability that there are 7 77 or more left-handed students in a class of 30 3030 students. Give your answer as either a fraction or a decimal. P ( 7 or more left-handed ) ≈ P(7 or more left-handed)≈P, left parenthesis, 7, start text, space, o, r, space, m, o, r, e, space, l, e, f, t, negative, h, a, n, d, e, d, end text, right parenthesis, approximately equals

In the past, professional baseball was played at the astrodome in houston, texas. the astrodome has a maximum height of 63.4 m. the height of a baseball t seconds after it is hit straight up in the air with a velocity of 45 ft/s is given by h = -9.8t2 + 45t + 1. will a baseball hit straight up with this velocity hit the roof of the astrodome? use the discriminant to explain your answer.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels.ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
