Answer:

see the explanation

Step-by-step explanation:

we have

Felicia

$-5(3x+2)+10x$

Apply distributive property

$-5(3x)-5(2)+10x$

$-15x-10+10x$

Combine like terms

$-5x-10$

Let

a ----> the missing term with coefficient x in Gregory's expression

b ----> the missing constant term in Gregory's expression

$-12-4x+ax+b$

equate Gregory's expression to Felicia's expression

$-12-4x+ax+b=-5x-10$

$-12+b=-10$ -----> $b=2$

$-4x+ax=-5x$ ------> $a=-1$

Gregory's expression is

$-12-4x+2-x$

therefore

The missing terms are 2 and -x

Ln (1/x)+ln (2x^3)=ln3

Lapatulllka [165]

$\ln \frac{1}{x} +\ln2x^3=\ln3$
$\ln \frac{2x^3}{x} = \ln3$
$\ln2x^2=\ln3$
$2x^2=3$
$x=\sqrt{ \frac{3}{2} }$

Definition of a random sample

Gnesinka [82]

Answer:

Step-by-step explanation:

In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process, and each subset of k individuals has the same probability of being chosen for the sample as any other subset of k.
