The percentile rank for 10 will be 10th.

<h3>What is percentile rank?</h3>

The percentile rank of a particular score in statistics refers to the percentage of scores in the frequency distribution that are smaller than that score.

Percentile rank = [(Number of values below x) + 0.5]/ total number of values * 100

For 10,

Percentile rank = {[0 + 0.5]/5} x 100 = 10th

For 15,

Percentile rank = ([1 + 0.5]/5) x 100 = 30st

For 19,

Percentile rank = [2 + 0.5]/5 x 100 = 50th

For 23,

Percentile rank = [3 + 0.5]/5 x 100 = 70th

For 30,

Percentile rank = [4 + 0.5]/ 5 x 100 = 90th

The percentile rank for 10 will be 10th.

missed my lecture and need help with this derivative, I tried looking at online resources but I just got confused so if someone

Zigmanuir [339]

Derivative with respect to x: $12x^2y^2-\frac{z^3}{x}+16x^{15}$

Derivative with respect to y: $8x^3y-4e^zy^3+4$

Derivative with respect to z: $-e^z y^4 +\frac{3z^2}{x^2}$

Step-by-step explanation:

We can calculate three derivatives for this function: the derivative with respect to x, the derivative with respect to y, and the derivative with respect to z.

We start with the derivative with respect to x:

$\frac{df}{dx}=4(3x^{3-1})y^2 -0 +z^3(-x^{-1})+0-16x^{16-1}=\\=12x^2y^2-\frac{z^3}{x}+16x^{15}$

Then we calculate the derivative with respect to y:

$\frac{df}{dy}=4x^3(2y^{2-1})-e^z(4y^{4-1})+0+4y^{1-1}=8x^3y-4e^zy^3+4$

Finally, we calculate the derivative with respect to z:

$\frac{df}{dz}=0-e^z y^4 +\frac{3z^{3-1}}{x^2}+0-0=-e^z y^4 +\frac{3z^2}{x^2}$

For the trapezoid below, what is the correct term for RT?

pickupchik [31]

The correct answer is a Leg (answer A).

An apothem would be a segment a segment formed formed from the center of a regular polygon that intersects one of its sides at 90°. In a trapezoid, the sides adjacent to the bases (because there’s two bases) are called legs.

Answer:

15

Step-by-step explanation:

Let volume of container = x

1/6x + 5 = 1/2x

x/6 + 5 = x/2

Multiply through by 6

x + 30 = 3x

Subtract 30 from both sides

x + 30 - 30 = 3x - 30

x = 3x - 30

x - 3x = - 30

-2x = - 30

x = 30 /2

x = 15
