After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:

where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:

b) After 200 years (t = 200), the amount of Cesium remaining is:

Hence after 200 years, 9.84 grams of Cesium would remain

Answer:7
Step-by-step explanation:
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3
