Javier read a report that said the probability that a randomly selected American is left-handed is 14%, percent. 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.

Give your answer as either a fraction or a decimal.

P(7 or more left handed) = (answer)

(-1,-0.5)

step-by-step explanation:

b if for most of the graph

d if y intercept

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
