A warehouse supply worker accidentally misreads the number 75 as 57. What percent change did the reading error result in?

snow_lady [41]

The percent change is 24 % due to reading error

Solution:

Given that a warehouse worker misread the number 75 as 57

To find: percent change due to reading error

Step 1:

Find the difference between the correct number and misread number

75 - 57 = 18

Step 2:

Calculate the percentage change due to reading error

$\text{ Percent change }= \frac{difference\ between\ numbers}{correct\ number} \times 100$

$Percent\ change= \frac{18}{75} \times 100$

$\rightarrow \frac{18}{75} \times 100 = 0.24 \times 100 = 24$

Thus the percent change is 24 % due to reading error

A group of 4 friends likes to golf together, and each friend keeps track of her all-time lowest score in a single round. Their l

Sphinxa [80]

Answer: Mean get decreased and median remains same.

Step-by-step explanation:

Given: The low scores of all 4 friends are all between 90 and 100, except for Angie, whose low score is 80.

i.e. Angie is an outlier.

[An outlier is an extreme value which lies far from the other data values.]

Angie then golfs a great round and has a new low score of 75.

i.e. more lower value.

Since Mean gets effected by an outlier but median remains same.

Here, value of new outlier(75) is less than the previous one (80), so mean score will get decreased, where as median (middle most value in ordered data) remains the same.

Geometry help!!

Eduardwww [97]

It would be A, Side Angle Side (SAS). Because you are given we congruent sides, and tow right angles. Using the reasoning of "If two two angles are both right angles then they are congruent" you can prove the angles congruent.

The reason it is not HL is because HL is used when it is given a right angle and the hypotenuse and one of the legs congruent. Therefore the only choice is Side Angle Side (SAS).
