Answer: systematic

Step-by-step explanation:

In random sampling researcher choose elements randomly for sample .
In convenience sampling individuals are selected as per his convenience and comfort.
In systematic sampling individuals are selected in a systematic way by using a fix periodic interval k from the entire population .
In cluster sampling clusters (of homogeneous elements) are selected to make a sample.

Given, When grading English papers, the instructor checks every 4th paper for plagiarism which expresses a fixed periodic interval.

Hence, this is systematic sampling.

An equilateral triangle and an isosceles triangle share a common side. what is the measure of ABC ?

erastovalidia [21]

Answer:

$\angle ABC=116^o$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of the vertex angle ∠ABD of an isosceles triangle

we know that

An isosceles triangle has two equal sides and two equal angles

In this problem

$\angle BDA=\angle BAD=62^o$ ----> the angles of the base are equals

Find the measure of the vertex angle ABD

$\angle ABD=180\°-2*62\°=56\°$ ------> the sum of the internal angles of a triangle is equal to 180 degrees

step 2

Find the measure of the angle ∠CBD in the equilateral triangle

we know that

A equilateral triangle has three equal sides and three equal angles

The measure of the internal angle in a equilateral triangle is equal to 60 degrees

$\angle CBD=60\°$

step 3

Find the measure of the angle ∠ABC

we know that

$\angle ABC=\angle ABD+\angle DBC$ ---> by addition angle postulate

substitute the values

$\angle ABC=56^o+60^o$

$\angle ABC=116^o$

Which function passes through the points (2, 3) and (4, 4)?

Rina8888 [55]

Answer:

C. y=1/2x+2

Step-by-step explanation:

1. Find the slope using the slope formula.

Slope formula: y2-y1/x2-x1

Let the y-value in the second ordered pair (4,4) be y2, and the 3 in the first ordered pair (2,3) be y1. 4 and 2 from these ordered pairs will be x2 and x1.

Plug these values into the equation and simplify.

4-3/4-2

=1/2

Slope is 1/2

2. Choose one of the ordered pairs and plug those numbers and the slope into the point-slope formula.

Point slope formula: y-y1=m(x-x1). M represents the slope, and the x1 and y1 represent the values of the ordered pair.

Let's use the pair (4,4).

y-4=1/2(x-4)

3. Simplify the equation to convert to y=mx+b format.

Multiply the inside of the parentheses by 1/2.

y-4=1/2x-2

Add 4 to both sides.

y=1/2x+2

3. C is your answer, for it matches what you found in the calculations.
