So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4

'of' can be roughly translated as multiply

so 2/3 times 3/4 =6/12=1/2 lb left

or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb

First arrange in ascending order of time:-

7, 8, 10, 12, 14, 15, 18, 20, 26, 30, 30, 30, 35, 35, 42, 55

MOde is the value occuring mos = 30.

Median is the mean of 2 middle numbers = (20 + 26) / 2 = 23

Mean = sum of the 16 numbers / 16 = 387/16 = 24.2

mixer [17]

Answer:

$96

Step-by-step explanation:

let the the amount each men pay when they were 8 be x

let the total amount for the boat rental be y

8x=y .....................equ1

if two men withdraw from the party, and the amount each men pay increases by $4 then;

(x+4)6 =y

6x+24=y ...........equ2

make x the subject of formula from equ1;

x=y/8

substitute x as y/8 into

6(y/8) +24 =y

3y/4 +24=y

24=y-(3y/4)

$24=\frac{4y-3y}{4}$

24=y/4

y=24*4

y=$96
