First you need to know the definition of a complementary angle. That means that two angles add up to 90 degrees, or a right angle.
To find an angle complementary to a 78 degree angle, you need to subtract 78 from 90.
90 - 78 = 12

Most of the time you can go on a website that can cauculate it.
Step-by-step explanation:
How to cauculate the MAD:
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.
What is the mode of the following set of data? 34, 23, 12, 11, 11, 25, 25, 26, 25, 27, 30

1 - B
Mode - The mode the number that appears most often in a data set. In this question, 25 was repeated 3 times and no other ones where repeated 3 times. Thats why 25 is the mode.
2 - D
Median - The middle number of a data set that is arranged from least to greatest.
3 - True
There is no mode because all of the numbers only appear once.
4 - A
5 - C
Answer:
Step-by-step explanation:
Convert 
to a decimal
Step 1. Reduce the fraction to its lowest terms.
Divide both numerator and denominator by their greatest common factor (12)
Step 2. Convert the denominator to a power of 10
Multiply both numerator and denominator by 2.
Step 3. Divide the numerator by the denominator
Dividing by 10 moves the decimal point one place to the left.
Answer:
213.41 mph.
Step-by-step explanation:
Multiply by 3600 ( seconds in an hour) and divide by 5280 (feet in a mile).
= 213.41 mph.
