Ameteorologist forecasted that monday's high temperature would be 76°f. on monday,
the temperature reached 80°f.
what is the percent error in the meteorologist's forecast for monday?

The percent error in the meteorologist's forecast for Monday is 5.26316 %

Given that Monday's high temperature would be 76°F

On Monday,  the temperature reached 80°F

To find:  percent error in the meteorologist's forecast for Monday

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

The percent error is given as:

Here standard value = 76 and observed value on monday = 80

Thus percent error in the meteorologist's forecast for Monday is 5.26316 %

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.

step-by-step explanation:
