By definition, when a test or technique measures what it intends to, it is valid.

The answer is option A.

The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).

Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).

Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).

The output of a plant is 4335 pounds of ball bearings per week (five days). If each ball bearing weighs 0.0113 g, how many ball
Setler79 [48]

Answer:

The plant makes 34,802,178 ball bearings in a single day

Step-by-step explanation:

The total output of a plant in a 5-day week is 4335 pounds

Each ball bearing weighs 0.0113g

We are to calculate the number of ball bearings made per day

First, we ensure both mass are in the same unit

Now 1 pound =453.5924 grams

4335 pounds=453.5924 X 4335 =1966323.054 grams

Number of bearings made in a week therefore

= 1966323.054 /0.0113=174010889.7

≈174010890 (to the nearest whole number)

Since there are 5 days in a week of production,

Daily Production=174010890/5

=34802178

The plant makes 34,802,178 ball bearings in a single da

Can you’ll help me pls
Rasek [7]

Answer:

1. 48 sticks, 49 dots

2. 60 sticks, 61 dots

3. figure 13, 157 dots

Step-by-step explanation:

The pattern increases by 12 sticks each time. The number of dots is equal to the number of lines plus 1. An easy way to figure it out is to multiply the figure number by 12 to find the number of lines and then add one more for the number of dots. To solve 3, divide the number of sticks by 12 to find the figure number, and add one to the number of sticks to get the number of dots.

The graph of which of the following equations contains the points (2, 3) and (3, 2)?
IceJOKER [234]

Answer:

(2, 3) lies on the line y = 5 - x.  

Step-by-step explanation:

Were there only two possible answer choices?

We can determine whether or not a given point, such as (2, 3), is contained in a function such as y = x - 1, by substituting the given coordinates 2 and 3 for x and y respectively; is the resulting equation true or false?

Check out (2, 3) and y = x - 1:  3 = 2 - 1, or 3 = 1.  False.  (2, 3) does not lie on the line y = x - 1.  Does (2, 3) lie on the line y = 5 - x?  Is 3 = 5 - 2 true?  Yes.  So (2, 3) lies on the line y = 5 - x.

Check out (2, 3) and y = 7 - 2x.  Is 3 = 7 - 2(1) true?  No, it is not true.
