\huge\textsf{Hey there!}

\bullet \large\textsf{ Finding the mean you have to add up all of your numbers \& divide it}\\\large\textsf{by the total numbers in your data plot}

\mathsf{\dfrac{20 + 5 + 45 +  90 + 60 + 45 + 30 + 10 + 20+ 45 + 15 + 25}{12}}

\mathsf{20 + 5 + 45 +  90 + 60 + 45 + 30 + 10 + 20+ 45 + 15 + 25}

\mathsf{= 25 + 45 + 90 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}

\mathsf{= 70 + 90 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}

\mathsf{= 160 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}

\mathsf{= 220 + 45 + 30 + 10 + 20 + 45 + 15 + 25}

\mathsf{= 265 + 30 + 10 + 20 + 45 + 15 + 25}

\mathsf{= 295 + 10 + 20 + 45 + 15 + 25}

\mathsf{= 305 + 20 + 45 + 15 + 25}

\mathsf{= 325 + 45 + 15 + 25}

\mathsf{= 370 + 15 + 25}

\mathsf{= 385 + 25}

\mathsf{= \bf 410}

\mathsf{= \dfrac{410}{12}}

\mathsf{\dfrac{410}{12} \approx \bf 34.1667}

\boxed{\boxed{\huge\textsf{Thus, your ANSWER is: \boxed{\mathsf{ \bf \underline{{\star 34.1667\star}}}}}}}}\huge\checkmark

\huge\textsf{Good luck on your assignment \& enjoy your day!}

elixir [45]

Answer: 2r(0)/3.

Step-by-step explanation:

So, we are given one Important data or o or parameter in the question above and that is the function of the form which is given below(that is);

S(r) = (r0 - r) ar^2 -----------------------------(1).

We will now have to differentiate S(r) with respect to r, so, check below for the differentiation:

dS/dr = 2ar (r0 - r ) + ar^2 (-1 ) ---------;(2).

dS/dr = 2ar(r0) - 2ar^2 - ar^2.

dS/dr = - 3ar^2 + 2ar(r0) ------------------(3).

Note that dS/dr = 0.

Hence, - 3ar^2 + 2ar(r0) = 0.

Making ra the subject of the formula we have;

ra[ - 3r + 2r(0) ] = 0. -------------------------(4).

Hence, r = 0 and r = 2r(0) / 3.

If we take the second derivative of S(r) too, we will have;

d^2S/dr = -6ar + 2ar(0). -------------------(5).

+ 2ar(0) > 0 for r = 0; and r = 2r(0)/3 which is the greatest.

All of the following proportions are equivalent except a/b=c/d b/a=d/c a/d=c/b a/c=b/d
valentina_108 [34]
I believe the correct answer from the choices listed above is the third option. All of the following proportions are equivalent except <span>a/d=c/b. 

</span><span>a/b=c/d

b/a=d/c => a/b = c/d


a/d=c/b not equal to </span>a/b = c/d<span>

a/c=b/d => </span>a/b = c/d
