we have
Complete the square
step 1
Group terms that contain the same variable, and move the constant to the opposite side of the equation
step 2
Complete the square. Remember to balance the equation by adding the same constants to each side
step 3
Rewrite as perfect squares
Jake's error in step 3
He placed 6 instead of 3 in the left side
step 4
take square root both sides
step 5
step 6
step 7
x=5 and x=1
The movies of 120 min or less than 120 mins are 100
Further explanation:
A histogram is a visual representation of data.
In the given histogram we can see that
5 movies are 0 to 30 minutes, 10 movies are 31 to 60 minutes, 30 movies are 61 to 90 minutes, 55 movies are 91 to 120 minutes, and 15 movies are over 120 minutes.
In order to find the number of movies which are 120 minutes long or less than 120 minutes we will add up all the number of movies with 120 length and less than that
So,
The movies of 120 min or less than 120 mins are 100
