What is a part of a population used to describe the whole group?
Helen [10]

Answer:

In basic terms, a population is the total number of individuals, animals, items, observation, data, etc. So the sample, in other words, is a portion, part, or fraction of the whole group, and acts as a subset of the population. Samples are used in a variety of settings where research is conducted.

What are the period and vertical shift of the cosecant function below?
lutik1710 [3]

Answer:

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\P=\frac{2\pi}{b}\Rightarrow P=\frac{2\pi}{\frac{1}{2}} \Rightarrow P = 2\pi*2 \Rightarrow P=4\pi\\d=2

Step-by-step explanation:

The trigonometric functions have some features like amplitude, period, phase shift, and vertical shift.

Retrieving the original cosecant graph and copying and attaching it below we have this function:

y=cosec(\frac{1}{2})x+2

1) Period

Since the period of a basic secant and basic sine function 2\pi

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\P=\frac{2\pi}{b}\Rightarrow P=\frac{2\pi}{\frac{1}{2}} \Rightarrow P = 2\pi*2 \Rightarrow P=4\pi

2) Vertical Shift

This value affects the graph by displacing it from x-axis.

The Vertical Shift does not need calculation for it is given by the parameter "d"

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\ d=2 \: (Vertical\:Shift)

Derivative Rule [Chain Rule]: \displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)

Step-by-step explanation:

<u>Step 1: Define</u>

h(x) = f(g(x))

h'(1) = ?

<u>Step 2: Differentiate</u>

  1. Chain Rule:                                                                                                        h'(x) = f'(g(x)) · g'(x)

<u>Step 3: Evaluate</u>

  1. Substitute in <em>x</em> [Derivative]:                                                                              h'(1) = f'(g(1)) · g'(1)
  2. [Values] Substitute in function values:                                                            h'(1) = f'(3) · -3
  3. [Values] Substitute in derivative function values:                                          h'(1) = -5 · -3
  4. Multiply:                                                                                                             h'(1) = 15

A bag contains 1 blue, 2 green, and 3 red marbles, as shown.
sleet_krkn [62]

Answer:

One-third

Step-by-step explanation:

The reason is because there are 3 red marbles with a total of 9. That then becomes 3/9. If you simplify that it turns into 1/3.
