Answer:

$\frac{dT}{dt} = -0.05\;min^{-1} (T-70\ºF)$

Step-by-step explanation:

Hi!

Lets call:

T = temprature of the object

T₀ = temperature of surroundings

t = time

The rate of change of T is its derivative with respecto to time. If T > T₀, the object looses heat, so T decreases. Then, being k > 0:

$\frac{dT}{dt} = -k(T-T_0) \\$

In this case T₀ = 70ºF and k = 0.05/min. Then the differential equation is:

$\frac{dT}{dt} = -0.05\;min^{-1} (T-70\ºF)$

A score that is 12 points below the mean corresponds to a z-score of z = -3.00. What is the population standard deviation?

vladimir1956 [14]

Standard deviation=4.

let the mean be 12 and the score be 0 (therefore 12 point difference.)

0-12/s=-3 (s being standard deviation)
-12/4 = -3
