Answer:

Step-by-step explanation:

The interquartile range is the difference between the upper quartile and the lower quartile.

The first step is to find the median which is the middle value of the data set arranged in ascending order.

10, 11, 12, 15, 17, 19, 22, 24, 29, 33, 38

↑ ↑median ↑

The lower quartile is the middle value to the left of the median.

The upper quartile is the middle value to the right of the median.

The lower quartile = 12 and the upper quartile = 29

Interquartile range = 29 - 12 = 17

Please help me solve -6 = 14 - z/3

dybincka [34]

Solve. -6 = 14 - z/3Subtract 14 from both sides

-20 = -z/3

Multiply -3 by both sides to get rid of the negative and 3 with the z.

z= 60

The reactants of two reactions are shown.

katovenus [111]

Answer:

The answer to your question is letter B.

Step-by-step explanation:

The correct answer is letter B because both Copper and Iron as reactants have an oxidation number of zero and when they have reacted their oxidation numbers would be different from those.

A redox reaction is a reaction that involves a transfer of electrons from one atom to another and the oxidation numbers of the reactants are different from the oxidation numbers from the products.

The rate of change of the number of squirrels S(t) that live on the Lehman College campus is directly proportional to 30 − S(t),

pishuonlain [190]

Answer:

S(3)=22

Step-by-step explanation:

The rate of change of the number of squirrels S(t) that live on the Lehman College campus is directly proportional to 30 − S(t).

$\dfrac{dS}{dt}=k(30-S(t))\\ \dfrac{dS}{dt}+kS(t)=30k\\$The integrating factor: e^{\int k dt}=e^{kt}\\$Multiply all through by the integrating factor\\ \dfrac{dS}{dt}e^{kt}+kS(t)e^{kt}=30ke^{kt}$

$(Se^{kt})'=30ke^{kt} dt\\$Integrate both sides\\ Se^{kt}=\dfrac{30ke^{kt}}{k}+C$ (C a constant of integration)\\Se^{kt}=30e^{kt}+C\\$Divide both sides by e^{kt}\\S(t)=30+Ce^{-kt}$
