Answer:
Transaction Fee = $10
Step-by-step explanation:
Transaction fee = $4 for ATM fees per foreign transaction + 3% of the withdrawal
Withdrawal = $200
3% of the withdrawal = 3/100 * $200 = $6
Transaction Fee = $4 + $6 = $10

A dental hygienist is a health-care professional who works alongside a dentist to meet the oral health care needs of patients. Asked by one of her clients who needs to get a cavity filled what the average number of cavities a person gets filled by the time they are 50 years old, the hygienist responds that she will gather and determine not just the average, but also the median and the mode - because she would like to know this information herself. A bit of research turns up the following data table taken from a research project of a graduate student. The graduate student surveyed 20 people aged 50 from around Idaho.

Choose a missing numbers that make the following expression equivalent ____x + 14 and 7 ( 5 x + _____ )
Answers
Answer:
35x + 14 and 7(5x + 2)
Step-by-step explanation:
We have to find the missing values that would also make both expressions equivalent.
_x + 14 and 7(5x + _ )
In the expression, there are some similarities with the placement of the numbers and variables.
Let find the value of the number next to "x".
You can see that we have to use the distributive property to solve the right expression, and once we do so, we can find our first value.
Use the distributive property:
7(5x)
35x
Now we know that our first value is 35x.
To find our second value, we see that in the first equation it is "14", so we need a number that can be multiplied by 7 to make 14.
7 · 2 = 14
Our second number would be 2.
Your final answer would be: 35x + 14 and 7(5x + 2)
Once you use the distributive property for the second expression, you would get an equivalent expression as the first one.
A sample of n = 4 scores has SS = 48. What is the estimated standard error for this sample? Group of answer choices
Answers
Answer:
2
Step-by-step explanation:
We have
n = 4 scores
SS = 48
For this question, we are required to find the estimated standard error
To get this, we first solve for the variance
S² = SS/n-1
= 48/4-1
= 48/3
= 16
Then S² = 16
S = √16
S = 4
Then the estimated standard error is given by:
S/√n
= 4/√4
= 4/2
= 2.
The estimated standard error is 2.

Answer:
For figure 1:
Area of rectangle = 7x + 21
For figure 2:
Area of rectangle = [tex]\mathbf{p^2-9p }[/tex]
Step-by-step explanation:
We need to find area of rectangle
The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]
For figure 1:
Length = 7
Width = x+3
Putting values in formula and finding area of rectangle
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times (x+3)\\Now,\: multiply\:7\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=7(x)+7(3)\\Area\:of\:rectangle=7x+21\\[/tex]
So, area of rectangle = 7x + 21
For figure 2:
Length = p
Width = p-9
Putting values in formula and finding area of rectangle
[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=p\times (p-9)\\Now,\: multiply\:p\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=p(p)-p(9)\\Area\:of\:rectangle=p^2-9p\\[/tex]
So, area of rectangle = [tex]\mathbf{p^2-9p }[/tex]

Answers
Answer:
Instant Variables
Step-by-step explanation:
A continuous variable is a variable defined as one which can receive an infinite set of values.
This continuous variable has two types namely instant variables and ratio variables.
Instant variables are those in which the distance between each category is equal or static. Meanwhile, ratio variables are those in which the ratio between the given scores provide information in regards to the relationship between the responses/dependent variables.
Thus, the one that corresponds to our question are instant variables.
