The question reads The graph of y=f(x) is shown below (dashed curve). Manipulate the green draggable points to obtain the graph of y=f(-x+4)-5 (solid curve). Someone help me please!!!

Answers

The graphs of y = f(x) and the transformed function are illustrations of function transformation

How to determine the graph of y=f(-x+4)-5

The parent function is given as:

y = f(x)

The lines and curves on the graph cannot be manipulated; however, the description of the function y=f(-x+4)-5 can be given

The transformation of function y = f(x) to y=f(-x+4)-5 is as follows:

First, the graph of y = f(x) is reflected across the y-axisNext, the graph is shifted right by 4 unitsLastly, the graph is shifted down by 5 units

Read the following scenarios and indicate the type of reliability in each scenario. Explain your answers
i) Test-retest reliability
ii) Parallel forms reliability
iii) Internal consistency reliability
iv) Interrater reliability
a) You want to evaluate the reliability of a critical thinking assessment. You create a large set of items that all pertain to critical thinking and then randomly split the questions into two sets of questionnaires. You administer both versions of the test to the same group of individuals. The scores from the two versions can then be correlated in order to evaluate the consistency of results across alternate versions.
b) You want to evaluate the degree to which the art portfolios in your 7th grade class meets the required standards. You ask 3 different art experts to evaluate the students' portfolios with the help of a rubric.
c) You are developing a math measure to test the constructs of number sense and logic of your 4th grade students. You want to make sure your measure is not testing other constructs like arithmetic skills. You would like to evaluate the degree to which different test items that probe the same constructs produce similar results.

Answers

Answer:

The Type of Reliability in each Scenario are:

Scenario   Type of Reliability Test

a)               Parallel forms reliability

b)               Interrater reliability

c)               Internal consistency reliability

Step-by-step explanation:

Types of Reliability Tests:  

Test-retest reliability = measures the results consistency with the application of the same test at different times.

Interrater reliability = shows consistent ratings by different examiners.

Parallel forms reliability = uses alternative versions of an equivalent test to probe for similar results.

Internal consistency reliability = this test checks the consistency of individual items of a test.

Yes; the domain values are at regular intervals and the range values have a common factor 4. d. Yes; the domain values are at regular intervals and the range values have a common factor 0.25.

Answers

Answer:

D

Step-by-step explanation:

No the function is not an exponential function as the domain values are not at regular intervals although the range values have a common factor.

What is exponential function?

The exponential function is a function which is formed by the unit e which is equal to 2.718.

How to identify function?

The differences between x-values are  -1, -1, -1, -2 . . . . not a constant difference

The ratios of y-values are 2/8 = 0.5/2 = 0.125/0.5 = 0.25 . . . . a constant difference

The domain values do not have a common difference shows the common factor of the range values which are of no use. So, the function is not exponential.

Hence the table does not show exponential function in any way because the domain values are at regular intervals and the range values have a common factor 0.25.

Answers

Step-by-step explanation:

1.)20x + 100 = 1440

-Let the number of couples be x. So, the total amount paid by all the couple’s are $20x. School paid $100 as security, so the total amount paid is

$ (20x + 100)

2.) 20x = 1440 - 100 ⇒ 20x = 1040

X = 52

3. ) The security money  is $100, so the couples paid $1440- 100 = $1040 in total. As the couples paid $ 20 each than- [tex]\frac{1040}{20}[/tex] = 52

Step-by-step explanation:

give them brain, they're correct.

The Unit Rate for Amy will be 22 pages per hour.

What is Unit Rate?

The Unit Rate is defined as means a rate for one of something.

We have,

Amy can read 88 pages in 4 hours.

So,

Now,

Number of pages Amy can read in 1 hour [tex]=\frac{88}{4}[/tex]

So,

Number of pages Amy can read in 1 hour = 22,

That means,

The  Unit Rate for Amy is 22 pages per hour.

Hence, we can say that the Unit Rate for Amy will be 22 pages per hour.
