Step-by-step explanation:
A school reserved a banquet hall for the spring dance. In addition to a $100 deposit, each couple must pay $20. If the total cost of the banquet hall is $1, 140. Compare and contrast the steps you used to solve the problem algebraically and arithmetically.
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

I tried but got the wrong answer. Can someone help and explain?
Answer:
I
Step-by-step explanation:
This is a dotted line so we can automatically eliminate, b, e, g, h, and j. The shading in greater than, so we can eliminate a, and d.
Now all we have left are c, f and *i,
*(because if converted to y intercept the sign will flip because the y is negative in this equation.)
Now convert to y intercept form (y=mx+b).
Flip the sign because some are negative.
C. y>(-5/2)x+0
F. y>-2x+9
I. y>(4/3)x-(5/3)
Now use rise over run, or you could just look at the b. B is equal to the y-intercept. It can't be 0 or 9, and (-5/3) is equal to -1.67. So isn't that the closest to what the y intercept looks like in the graph?
Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left. Which diagram best represents the story?
Answer:
C
Step-by-step explanation:
Which statement best
describes the function?
A. The function is always increasing.
B. The function is never increasing.
C. The function is increasing when x > 0.
D. The function is increasing when x < 0.
Answer:
C. The function is increasing when x > 0.
Step-by-step explanation:
Statement best describes the function, The function is increasing when x > 0.
We have given that,
A. The function is always increasing.
B. The function is never increasing.
C. The function is increasing when x > 0.
D. The function is increasing when x < 0.
What is the increasing function?
A function is increasing when the y-value increases as the x-value increases, like this It is easy to see that y=f(x) tends to go up as it goes along.
We have to determine the statement best describes the function.
Therefore,The function is increasing when x > 0.

From the table below, determine whether the data shows an exponential function. Explain why or why not. x 3 2 1 –1 y 8 2 0.5 0.125 a. No; the domain values are at regular intervals and the range values have a common factor 0.25. b. No; the domain values are not at regular intervals although the range values have a common factor. c. 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.
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.

hour?)
Help plzzzz
Answer:
22
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.

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.
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.
