The error percentage is 4.13%.

<h2>Error percentage</h2>

The amount of mistakes is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

<h3>To find </h3>

The error percentage.

<h3>How to find the error percentage?</h3>

We know the formula for the error percentage.

\rm \% Error = \dfrac{Measured \ value- Actual\ value}{Actual\ value} * 100\\\\ \% Error = \dfrac{78.25 - 75.50}{78.75}*100\\\\ \% Error = \dfrac{3.25}{78.75}*100\\\\ \% Error = 0.0413*100\\\\ \% Error = 4.13 \%

The error percentage is 4.13%.

More about the error link is given below.

Which equation can be used to find the length of Line segment A C? Triangle A B C is shown. Angle A C B is 90 degrees and angle
taurus [48]

<u><em>Answer:</em></u>

AC = 10sin(40°)

<u><em>Explanation:</em></u>

The diagram representing the question is shown in the attached image

Since the given triangle is a right-angled triangle, we can apply the special trig functions

<u>These functions are as follows:</u>

sin(θ) = opposite / hypotenuse

cos(θ) = adjacent / hypotenuse

tan(θ) = opposite / adjacent

<u>Now, in the given diagram:</u>

θ = 40°

AC is the side opposite to θ

AB = 10 in is the hypotenuse

<u>Based on these givens</u>, we will use the sin(θ) function

<u>Therefore:</u>

sin(40) = \frac{AC}{10}\\ \\AC = 10sin(40)

Stolb23 [73]

Answer:

6 is most directly associated with the flow rate of customers

Step-by-step explanation:

Reason:

0.25 is the number of customers in the gift shop at a given point of time is WIP inventory

7.5 is the average time spent by customer in the shop and it is the throughput time.

Flow rate = WIP inventory/Throughput time

=0.25/7.5

= 0.0333 per minute = 2 per hour or 6 per 3 hour as given in question.
