Find the mode and median of the data. A. mode = 41 median = 72 B. mode = 72 median = 94 C. mode = 94 median = 94 D. mode = 94 median = 72

Answers

mode means the number that apperss the most
median is the number in the middle when you arrange them in numerical order


ok so
you take the unbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones

so the th enumbers are

32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94


mode=most common number
94 appears 4 times which is most
mode=94

median is number in very middle number
20 terms
72 is in middle


mode=94
72=median

D is answer

Answer:

D

Step-by-step explanation:

You take the numbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones.

So the the numbers are:

32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94

Mode = Most common number

94 appears 4 times which is most

Mode=94

Median is number in very middle number

20 terms

72 is in middle

Mode = 94

Median = 72

What is |58| in absolute value?

Answers

"So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive (or zero)."

so your answer is { 58 } :)
The answer is 58 because there is no negative sign on the outside. For instance, -|58| this would be -58 since the negative sign is on the outside.

The answer:  59° .
______________________________________________
 
Explanation:
______________________________________________
 a + b +  c = 180 .

(in which, "a" , "b", and "c" represent the measurements (in degrees" of each of the THREE (3) angles in a triangle; which always add up to "180 degrees");
______________
Given "a = 65 degrees";  "b = 56 degrees"; Find "c" (the measurement of the "unknown" angle.).
____________________________________________
 a + b + c = 180 ;

65 + 56 + c = 180 ;  Solve for "c" .
__________________________________

  180 - (65 + 56)  = c  ;
___________________________

Note:  65 + 56 = 121 ;
_____________________________
So:  180 - (65 + 56)  = 180 - 121= 59 = c ;  ↔  c = 59 .
___________________________________________ 
The answer:  59° .
