Answer/Step-by-step explanation:
Given:
Data set for sandwich calories=> 242, 290, 290, 280, 390, 350
Mean: the mean is given as sum of all values in the data set ÷ total no. of data set given
Mean Absolute Value:
Step 1: find the absolute value of the difference between each value and the mean
|242 - 307| = 65
|290 - 307| = 17
|290 - 307| = 17
|280 - 307| = 27
|390 - 307| = 83
|350 - 307| = 43
Step 2: find the sum of all values gotten in step 1
65 + 17 + 17 + 27 + 83 + 43 = 252
Step 3: divide the result you get in step 2 by 6 to get the M.A.D
The Mean Absolute Value represents or gives us an idea how spread the data set for the number of sandwich calories are.
Thus, averagely, the number of calories of sandwich at the restaurant are far from the mean caloric value by 42 calories.

Answer:
λN N(0) = 6
N(t) = N₀e^(λt)
Applying the inital value condition
N(t) = 6e^(λt)
Step-by-step explanation:
Summarizing the information briefly and stating the variables in the problem.
t = time elapsed during the decay
N(t) = the amount of the radioactive substance remaining after time t
λ= The constant of proportionality is called the decay constant or decay rate
Given the initial conditions
N(0) = N₀ = 6
The rate at which a quantity of a radioactive substance decays () is proportional to the quantity of the substance (N) and λ is the constant of proportionality is called the decay constant or decay rate :
λN
N(t) = N₀e^(λt) ......equ 1
substituting the value of N₀ = 6 into equation 1
N(t) = 6e^(λt)
