Teresa estimates that the height of a giraffe in a zoo is 18 feet. In fact, it is 16 feet tall. What is Teresa's percent error? Use proportional relationships to solve the problem. Show all your work and round your answer to the nearest tenth.
Write this in kids' words plz
Teresa thinks the giraffe is 18 feet tall, but it is actually 16 feet tall. To find the percent error, we need to see how much Teresa's estimate differs from the actual height.
First, we find the difference between the estimated height and the actual height: 18 feet - 16 feet = 2 feet.
Next, we need to find what percent the difference is of the actual height. To do this, we divide the difference by the actual height and then multiply by 100: (2 feet / 16 feet) * 100 = 12.5%.
So, Teresa's percent error is 12.5%.
what does the (/) mean?
The symbol ("/") represents division. When we write "2 feet / 16 feet," we are indicating that we are dividing 2 feet by 16 feet.
You don't need to be so mean about it @♡Libianca♡ its not like they killed your cat smh
Sure, I can explain that in simpler terms for you!
To find the percent error, we need to compare Teresa's estimate to the actual height of the giraffe.
Teresa estimated the giraffe's height to be 18 feet, but the actual height was 16 feet. Now we need to find out how much Teresa's estimate differs from the actual height.
First, we subtract the actual height from the estimated height: 18 - 16 = 2
So Teresa's estimate was off by 2 feet.
To find the percent error, we need to compare the error (2 feet) to the actual height (16 feet) and express it as a percentage.
To do that, we divide the error (2 feet) by the actual height (16 feet): 2 ÷ 16 = 0.125
Now, we need to convert this decimal into a percentage. To do that, we multiply the decimal by 100: 0.125 × 100 = 12.5
So, Teresa's percent error is 12.5%.
In simpler terms, Teresa's estimate was off by 2 feet, which is about 12.5% of the actual height of the giraffe.
