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

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.

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)-5The 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:

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

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?

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.

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,

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.

A study of immunizations among school-age children in California found that some areas had rates of unvaccinated school-age children as high as 13.5%. Imagine a district in the state where 13.5% of children are unvaccinated. If three children are chosen randomly (assume they are not siblings) from this district, what is the probability that all three children have been vaccinated
Answer: 0.6472
Step-by-step explanation:
Given: The proportion of unvaccinated school-age children = 13.5%
Then, the proportion of vaccinated school-age children :p=100%-13.5%
= 86.5% = 0.865
Total children selected :n=3
Binomial probability formula:
[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]
The probability that all three children have been vaccinated :
[tex]P(X=3)=\ ^3C_3(0.865)^3(0.135)^0\\=(1)(0.647214625)\approx0.6472[/tex]
Hence, the required probability = 0.6472

6. Pop's Cycle Shop sells bicycles and tricycles. The number of bicycles is 1 less than 5 times the number
of tricycles. All the bicycles and tricycles together have a total of 154 wheels. Find how many bicycles
and tricycles are there.
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Linear equations.
Let the number of bicycles = x
and number of tricycles = y
the relationship given is,
x = 5y-1
number of wheels of bicycle = 2x and of tricycles=3y
and other relation is, 2x+3y = 154
so now substituting we get as,
==> 2(5y-1) +3y= 154
10y-2+3y = 154
13y = 154+2
=> y = 12
=> 12*3 = 36 wheels of tricycles
so, 154-36 => 118 wheels of the bicycle.
so the number of bicycles = 118/2 = 59
hence,
==> number of bicycles = 59 and tricycles = 12
