Plz answer these word problem and both question​

Answer»

Step-by-step explanation:

hello friend

1) Mean = sum of OBSERVATIONS/ no of observations

= 34+72+25+50+36+42+40+68+25+32+48+70+65+58+45/50

add those numbers and divide by 15

2) mode is most repeated value so mode is 25 which is repeated twice

3) median is mid value arrange the given observations in ascending or descending ORDER

25,25,32,34,36,40,42,45,48,50,58,65,68,70,72

so median is 45 which is mid term.

2)given

3(2x-1)+7x-8

by simplification we get 6x-3+7x-8

so 13X -11 is simplified expression

now substitute x = 2 in 13x- 11

we get 13(2)-11 = 26-11 =15

PLEASE calculate the mean.

hope it helps you

mark me brainliest if you like my explanation and answer
