HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!

Answers

Answer:

Her error in terms of inches was 2 inches while her percent error was 4.166%

Step-by-step explanation:

From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.

We convert the feet into inches because 12 inches are equal to a feet.

4 feet = 4 × 12 inches = 48 inches

4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches

Error in terms of inches = 50 inches - 48 inches = 2 inches.

Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.

% error = (difference in values / actual value) × 100

Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%

Answer:

A 4% difference

Step-by-step explanation:

Convert 4 feet 2 into 4.16666666

4/4.16666666= 0.96 or 96%

4 feet was 96% of 4 feet 2 in

100 - 96= 4%

And this shows that there was a 4% error.

D

Step-by-step explanation:

The inequality to represents this situation is x + 2x ≥ 45.

What is inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality'.

Given that, a band is selling candy bars for a fundraiser, Sierra sold some candy bars, Breanna sold twice as many candy bars as Sierra and together Sierra and Breanna sold no less than 45 candy bars

Let Sierra sold x bars, then, according to question,

x + 2x ≥ 45

Hence, the inequality to represents this situation is x + 2x ≥ 45.
