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.
Hope it helped!

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3
The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.
What is the equation?More than one variable may be present inside a linear equation.
An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
13 = -3 + z
Since, A + B = B + A
Thus, -3 + z can be written as z - 3
So, 13 = z - 3
Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".
