Answer:

If y(t) is the mass (in mg) remaining after t years, then y(t) = y(0) (0.5)^{t/T} = 400 (0.5)^{t /4}, where T is the half-life period and y(0) is the amount at t = 0 years (initial).

Then at t = 20:

y(20) = 400 (0.5)^{20 /4} = \text{12.5 mg}

lora16 [44]

Answer:

(a) is true

Step-by-step explanation:

Given

See attachment for box plots

Required

Which of the options is true?

Option A compares the IQR of both plots.

IQR is calculated using:

IQR = Q_3 - Q_1

Where

Q_1 \to Lower quartile

Q_2 \to Upper quartile

From the attached plots, we have:

Republican

Q_1 = 170.5

Q_3 = 356

So:

IQR = 356 - 170.5

IQR = 185.5

Democratic

Q_1 = 181

Q_3 = 367.5

So:

IQR = 367.5 - 181

IQR = 186.5

We have:

IQR = 185.5 --- Republican

IQR = 186.5 --- Democratic

<em>Hence, (a) is true</em>
