Answer:
a. Isosceles + Acute
b. Scalene + Right
Step-by-step explanation:
a. The side markers show that 2 sides are equivalent in length, making it isosceles. The angles are all noticeably under 90 degrees, resulting in it being acute.
b. There are no side markers whatsoever, making it scalene. There is a right angle marker, resulting in the triangle being right.
The percentage that the number of airlines with an average airplane age of 14 is less than the number of airlines with an average airplane age of 11 is:
B. 20%.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
The percentage of airlines with an average age of 14 years is:
The percentage of airlines with an average age of 11 years is:
The difference is:
33.33% - 13.33% = 20%.
Hence option B is correct.

Convert all of them in decimals
3 ÷ 10 = 0.3
0.4
35% ÷ 100 = 0.35
Order from least to greatest--
3/10, 35%, 0.4
3/10 is the smallest
Answer:
Option B. Standard error of predicted amount.
Step-by-step explanation:
A standard error predicted amount will work best in this scenario. The data, when extracted from the standard mean, provides the most accurate presentation of the statistical data on question. By using the standard error, the variation from the central point can be determined.
