Four students found the mean of the data set 26, 31, 39, 30, 16, 16, 18, 38. which student found the correct mean? ashrita's work 26 +31 +39+30+ 16 + 16+ 18+ 38 26.75 collette's work 26 +3864 - 32 daniel's work 26+31+39 + 30+ 16+ 18+ 38 198 - 28.29 lora's work 30+ 16 - 46 - 23

Ashrita

Step-by-step explanation:

The mean of any set of data is found by finding the summation of all the values in the set of data then dividing it by the number of entries in the data.

Mean=Σfx/Σf

Σf=26+31+39+30+16+16+18+38= 214

Σf= 8= the number of entries.

Mean=214/8=26.75

Ashrita's work was correct.

answer: the answer is 127 degrees

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
