Each question is either true or false, so the sample space is 2, true and false, two states only.
what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.
what's the probability that she got all four correct, we simply multiply the probability of each,
Answer/Step-by-step explanation:
Exercise 5:
a. 180 pages was read in 5 days
Unit rate = pages per day = 180 pages ÷ 5 = 36 pages per day.
b. Number of pages of the book = 765 pages
Unit rate = 36 pages per day
Number of days to read the book = 765/36 = 21.25
It will take Kirk about 22 days to finish reading the book.
Y=-7x-15
The formula to write the equation is
Y=mx+b
m=slope
m=-7
b=y intercept
b=-15
Answer: 4/15 of the movie
Step-by-step explanation:
In the morning, Charlie watched ¹/₃ of a movie. He then watched some more at night.
At the end of the day, he still had ²/₅ of the movie to watch.
The proportions of an item must always add up to one. This means that if you added the 1/3 to the 2/5 and then to the fraction Charlie watch at night, they should add up to one.
¹/₃ + ²/₅ + x = 1
x = 1 - ¹/₃ - ²/₅
