Answer:
100 x 4 = 400 - 91 = 309
Step-by-step explanation:
(12,200 + 16,211 + 12,050 + 11,350 + 13,325) / 5 = 65136/5 =
13027.2 <== this is the mean (average)
11,350 , 12,050 , 12,200 , 13,325, 16,211
median (middle number) = 12,200
there is no mode...a mode is a number that appears most often...all the numbers appear once in this data.
Answer:

Step-by-step explanation:
An Albert Einstein iconic math problem.
Answer:
B) SAS
Step-by-step explanation:
The angles between the two known equal sides are called a vertical angle and are equal. Thus you know Side-Angle-Side proves congruency.
To find the hypotenuse of a right triangle you can use the Pythagorean theorem. (a² + b² = c²) Using the measurements provided we can solve like this.
Both a² & b² = 7²
7 x 7 = 49
49 + 49 = 98
Now we need to find the square root of 98 (c²) to get our answer.
9.9 x 9.9 = 98.01 or about 98
The measurements for the tirangle are 7 units, 7 units, and 9.9 units.
Hope this helps!
