To start this problem, we know that one of the three pieces that the string is cut into is 15 meters longer than the others. Subtract 15 from 42 to get 27.
Then, from there, you can cut that number (<em>divide</em>) by three to get the length of the two shorter strings. Simply add the 15 meters you didn't use yet to one of the pieces to find the longer string, and you have your lengths.
Hope this helps!

Answer:
It is not a Type I error neither a Type II error.
Step-by-step explanation:
Let
be the true mean match score. The null hypothesis is
and the alternative hypothesis is
(upper-tail alternative). When the test shows that the mean match score is more than 80 when actually is equal to 80 a Type I error is made. On the other hand, when the test shows that the mean match score is equal to 80 when actually is more than 80 a type II error is made. Therefore, when the test shows that the mean match score is more than 80 when the person does not actually have a fingerprint match, does not correspond to a Type I error neither to a Type II error.

Step-by-step explanation:
A sales tax is placed on goods and services once the buyer and seller agree on what the exchange of currency is.
In this case you take the tax on the 1625 and not the 1803.75.
The buyer agreed to buy the item for 1625 and the seller agreed to sell it for that amount. So the tax goes on 1625.
Tax amount = total price - selling price
Tax amount = 1803.75 - 1625
Tax amount = 178.75
That's not what you want. You want the % of the tax.
% Tax = (Tax Amount / Selling Price) * 100
% Tax = (178.75 / 1625) * 100
% Tax = 0.11 * 100
% Tax = 11% Answer
That is not possible to make a triangle with a right angle and a acute angle because a acute triangle only has acute angles and a right triangle has a obtuse angle in it
