As the sum of marks of others remain unchanged , let their sum be x . As the mean using 83 was 40 , we have ,
(x +83)/100 = 40
x + 83 = 4000
x = 3917
Now mean using 53 ,
(x +53)/100
(3917+53)/100
39.7.
Hope it helps , plz mark as brainiest :-)

Answer:
The indifference point is 8 weeks.
Step-by-step explanation:
<u>First, we establish the total cost formula for each:</u>
x= number of weeks
Club:
Total cost= 20 + 15*x
Retail:
Total cost= 17.5*x
<u>Now, we equal both formulas and isolate x:</u>
20 + 15x = 17.5x
20 = 2.5x
8=x
The indifference point is 8 weeks.
<u>Prove:</u>
Total cost= 20 + 15*8= $140
Total cost= 17.5*8= $140

Here are some answers
<u>Remember if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)</u>
<u>if leg b is unknown, then. b = √(c² - a²)</u>
<u>for hypotenuse c missing, the formula is. c = √(a² + b²)</u>
Have a wonderful day!
