Answer:
a. E(a) = (a+1)²
b. E(a + h) = (a+h+1)²
c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h
Step-by-step explanation:
E(z)=(z+1)²
E(a) = (a+1)²
E(a + h) = (a+h+1)²
E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

What is the length of the segment shown below. Round your answer to the nearest hundredth. (2,5) (-4,-1)
Answer:
Step-by-step explanation:
use the distance formula Emily P1=(x1,y1)=(2,5) P2=(x2,y2)=(-4,-1)
d = [tex]\sqrt{(x2-x1)^{2}+ (y2-y1)^{2} }[/tex]
d = [tex]\sqrt{6^{2}+ 6^{2} }[/tex]
d = 8.48528
d = 8.49
Find the value of (x) in the triangle shown below.
A sample of n = 4 scores has SS = 48. What is the estimated standard error for this sample? Group of answer choices
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.

Choose a missing numbers that make the following expression equivalent ____x + 14 and 7 ( 5 x + _____ )
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.

how do you solve 9 tenths minus 13 fiftenths
Answer:
0.04
Step-by-step explanation:
1. 9/10 = 0.9 and 13/15 = 0.86
2. Subtract 0.9 and 0.86
3. You should end up with 0.04
Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.

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]

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.
Patient ID# Cavities Filled

a. What is the mean (average) number of cavities a person gets filled by age 50?
b. What is the median number of cavities a person gets filled by age 50?
c. What is the most often an occurring number of cavities filled in this data set?
Answer:
a. The mean number of cavities a person gets filled by the age of 50 is 7.1.
b. The medium number of cavities a person gets filled by the age of 50 is 8.
c. The most occuring number of cavities filled in the data set is 8.

Continuous variable expected to show a statistical relationship with dependent variables are called ____
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.

Shelley is visiting from London and uses her ATM card to withdraw $200 at local bank B. If local bank B charges $4 for ATM fees per foreign transaction plus 3% of the withdrawal, how much would she own in fees for what transaction? Round to the nearest dollar amount, such as: $6
$5
$4
$10
$7
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
