Answer:
77 pots
Step-by-step explanation:
To find how many pots he washes in 1 3/4 hours, multiply 44 by 1.75, since
3/4 = 0.75.
44(1.75)
= 77
So, Randy can wash 77 pots in 1 3/4 hours
Answer:
77
Step-by-step explanation:
He washes 11 every quarter of an hour, so just add 33 to 44

F(x)=x/x-9
Answer:
All Real x (x not = 9).
Step-by-step explanation:
When x = 9, f(x) = 9/0 which is undefined.
So the Domain is All Real x, x not = 9.
Answer:
Find the domain by finding where the expression is defined.

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.

Find the Unit Rate
Amy can read 88 pages in 4 hours. What is the
unit rate? (How many pages can she read per
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.

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

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

Jason makes a credit card purchase for $3000 that compounds interest daily. The APR is 4%. How much interest is earned on Jason's card after 1 year if Jason makes no payments?
The amount of interest earned on Jason's card after 1 year is $
Step-by-step explanation:
step 1. A = P(1 + r/n)^nt. this is the compounding equation where n is the number of compounds in a time t and P is the original amount. r is the rate.
step 2. A = 3000(1 + .04/365)^(365(1))
step 3. A = 3122.43. this is the total amount owed on the credit card which includes principle and interest. the interest is less 5he principle
step 4. 3122.43 - 3000 = 122.43
