In studies that use more than one data collector, how is the consistency of the data evaluated?.

Answers

Answer 1

The way that the consistency of data is evaluated if more than one data collector is used is; Inter - rater reliability

How to find consistency in data research?

When researching data about anything, it is pertinent to note that sometimes, we have to use more than one data collector just to get a more thorough result which only one person may not be able to generate.

Now, the way that consistency of data is evaluated when more than one data collector is used is via Inter-rater reliability. This is because Inter-rater reliability is the extent to which two or more raters or observers agree.

The benefit of Inter-rater reliability is that It addresses the issue of consistency of the implementation of a rating system. Inter-rater reliability can be evaluated by using a number of different statistics.

Parallelogram ABCD is adjacent to rhombus DEFG, as shown below, and F C intersects A D at H. image If m ∠ B = 126 ° and m ∠ A H C = 142 ° , determine and state m ∠ G F H .

Answers

A quadrilateral in which opposite sides are parallel is called a parallelogram. The measure of the ∠GFH is 16°.

What is a parallelogram?

A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

For a parallelogram and a rhombus opposite sides are parallel, therefore, the sides that are parallel are,

AB║DC║ED║FG

Since the sides are parallel,

∠ABC = ∠FGH = 126°

Also, ∠AHC and ∠GHF lie on the same line, therefore,

∠AHC + ∠GHF = 180°

∠GHF = 180° - 142° = 38°

Now, in ΔGHF

∠GHF + ∠HFG + ∠GFH = 180°

∠GFH = 180° - 126° - 38°

∠GFH = 16°

Hence, the measure of the ∠GFH is 16°.

Answer: Number = 1.3

Step-by-Step Solution:

Let the Unknown Number be ‘x’

• Six less than the product of twice a number and ten is twenty

Framing the Equation :-

Six less than => - 6
Twice a number => 2x
Product of 2x and ten => 2x * 10

=> (2x * 10) - 6 = 20

Solving the Equation :-

(2x * 10) - 6 = 20
20x - 6 = 20
20x = 20 + 6
20x = 26
x = 26/20
x = 13/10
=> x = 1.3

Hence, the Unknown Number = 1.3

Please help! What is 7 days 8 hours 20 minutes - 4 days 10 hours 30 minutes?

Answers

Answer:

2 days 21 hours and 50 minutes

Step-by-step explanation:

There are a couple of ways to solve this. Here is my approach

Convert everything to the lowest unit ie minutes, find the difference and then find the equivalent days, hours and minutes

Note

1 hour = 60 minutes

1 day = 24 hours * 60 minutes/hour = 1440 minutes

So,

7 days, 8 hours, 20 minutes = 7 * 24 * 60 + 8 * 60 + 20 = 10580 minutes
4 days, 10 hours, 30 minutes = 4 * 24 * 60 + 10 * 60 + 30 = 6390 minutes

Difference(elapsed time) = 10580 - 6390 = 4190 minutes

Convert 4190 to days, minutes and hours. This is a process of using whole division to find the quotient and remainder successively

For days, divide by 1440 which is the number of minutes in a day:
4190 minutes ÷ 1440 minutes = 2 whole days  with remainder of 1390 minutes

For hours divide by 60 which is the number of minutes in an hour:
the remainder 1390 minutes ÷ 60 minutes = 21 whole hours with remainder of 50 minutes

So 4190 minutes == 2 days, 21 hours and 50 minutes

what is the price of a $90 mobile phone after a 30% discount

Answers

Answer:

$ 63

Step-by-step explanation:

Let the new price ( price after the discount ) be x.

Old price                    Discount                     New price

 100                              30                                  70

  90                               30                                   x

Now we can make an expression like this to solve this

100  ⇒  70

90  ⇒ x

Use cross multiplication to solve for x.

100x = 70 × 90

100x = 6300

Divide both sides by 100.

x = $ 63

Answer:

Discount: $27.00

Final Price: $63.00

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 90 × 30/100

Discount = 90 x 0.3

You save = $27.00

Final Price = Original Price - Discount

Final Price = 90 - 27

Final Price = $63.00
