Calvin evaluated Negative two-thirds times 5 and one-sixth using the steps below. Step 1: Negative two-thirds time (5 + one-sixth) Step 2: (Negative two-thirds + 5) times (Negative two-thirds + one-sixth) Step 3: 4 and one-third times negative one-half Step 4: Negative 2 and one-sixth Which describes Calvin’s error? In step 1, he incorrectly broke up 5 and one-sixth. In step 2, he distributed the Negative two-thirds instead of the 5. In step 2, he confused the multiplication and addition signs. In step 3, he computed the addition and multiplication incorrectly.

In step 2, he confused the multiplication and addition signs

Step-by-step explanation:

In step 2, he confused the multiplication and addition signs.

Step-by-step explanation:

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
