Steps to solve:

-k^2 - (3k - 6n) + 2n; k = -3, n = -5

~Substitute ans simplify

-(-3)^2 - (3(-3) - 6(-5)) + 2(-5)

3^2 - (-9 + 30) - 10

~Use PEMDAS and solve the rest

9 - 21 - 10

-13 - 10

-23

Best of Luck!

<h3>Probability and Random sampling</h3>

According to the task content;

A statement of fact indicates that; 20% of the calculators produced in a factory are faulty.

Hence, it follows that, when a sample of 10 calculators is selected randomly each day, 2 of the calculators are faulty by proportion.

Ultimately, the probability that in any one sample, two calculators or less will be faulty is; 100%.

Evaluate the iterated integral. (give an exact answer.)int_0^4 int_x^(2x) int_0^y text( ) 2xyz text( ) dz text( ) dy text( ) dx

steposvetlana [31]

$\displaystyle\int_{x=0}^{x=4}\int_{y=x}^{y=2x}\int_{z=0}^{z=y}2xyz\,\mathrm dz\,\mathrm dy\,\mathrm dx$

$2xy\displaystyle\int_0^yz\,\mathrm dz=2xy\left[\frac{z^2}2\right]\bigg|_{z=0}^{z=y}=xy^3$

$x\displaystyle\int_x^{2x}y^3\,\mathrm dy=\frac{15}4x^5$

$\displaystyle\frac{15}4\int_0^4x^5\,\mathrm dx=\dfrac{15}{24}4^6=2560$
