Answer:
Her wage on the 8th day is $105 ⇒ answer d
Step-by-step explanation:
* Lets explain how to solve the problem
- The average of set of data = The sum of data/the number of data
- The sum of data = the average of set of data × the number of data
∵ Cindy worked for 15 consecutive days
∵ She is earning an average wage of $91 per day
∴ Her total earning = 91 × 15 = $1365
∵ Her average earning during the first 7 days is $87 per day
∴ Her total earning in the first 7 days = 87 × 7 = $609
∵ Her average earning during the last 7 days is $93 per day
∴ Her total earning in the last 7 days = 93 × 7 = $651
- Her total earning in the 14 days is the sum of the earning in the
first 7 days and the earning during the last 7 days
∵ Her total earning in the 14 days = 609 + 651 = $1260
∵ Her total earning in the 15 days is $1365
- To find her wage on the 8th day subtract her wage of the 14 days
from her wage of the 15 days
∴ Her wage on the 8th day = 1365 - 1260 = $105
* Her wage on the 8th day is $105

Triangles A B C and A double-prime B double-prime C double-prime are shown. Triangle A double-prime B double-prime C double-prime is smaller and to the right of triangle A B C. Which transformations could have taken place to map △ABC to △A"B"C"? a reflection and a dilation a rotation and a dilation a translation and a dilation a reflection and a translation
PLEASE I NEED HELP ASAP
A smaller shape would be a dilation.
A move to the right would be a transition. (As long as the letters for the triangle are in the same orientation).
The answer should be:
A dilation a translation
There are various types of transformations that can be applied to a coordinate point. The new point could become compressed/enlarged, reflected, rotated, etc.
The transformations that transform [tex]\triangle ABC[/tex] to [tex]\triangle A"B"C"[/tex] are a translation and a dilation.
Given that:
[tex]\triangle A"B"C"[/tex] is smaller than [tex]\triangle ABC[/tex]
This means that sides of [tex]\triangle ABC[/tex] were dilated (i.e. compressed) to give the sides of [tex]\triangle A"B"C"[/tex]
Also:
[tex]\triangle A"B"C"[/tex] is at the right of [tex]\triangle ABC[/tex]
This means that [tex]\triangle ABC[/tex] was translated (i.e. shifted) to give [tex]\triangle A"B"C"[/tex]
Hence, the correct option is: a translation and a dilation.

How can I Factor 9x2-1
Answer:
17 = 17^1
Step-by-step explanation:
Factor the following integer:
17
17 is not divisible by 2 since 17 is odd and 2 is even:
17 = 17 (17 is not divisible by 2)
The sum of the digits of 17 is 1 + 7 = 8, which is not divisible by 3. This means 17 is not divisible by 3:
17 = 17 (17 is not divisible by 2 or 3)
The last digit of 17 is not 5 or 0, which means 17 is not divisible by 5:
17 = 17 (17 is not divisible by 2, 3 or 5)
Divide 7 into 17:
| | 2 | (quotient)
7 | 1 | 7 |
- | 1 | 4 |
| | 3 | (remainder)
17 is not divisible by 7:
17 = 17 (17 is not divisible by 2, 3, 5 or 7)
The alternating sum of the digits of 17 is 1 - 7 = -6, which is not divisible by 11. This means 17 is not divisible by 11:
17 = 17 (17 is not divisible by 2, 3, 5, 7 or 11)
Divide 13 into 17:
| | | 1 | (quotient)
1 | 3 | 1 | 7 |
| - | 1 | 3 |
| | | 4 | (remainder)
17 is not divisible by 13:
17 = 17 (17 is not divisible by 2, 3, 5, 7, 11 or 13)
No primes less than 17 divide into it. Therefore 17 is prime:
17 = 17
Since 17 is prime it has an exponent of 1:
Answer: 17 = 17^1

f(x)=-2x+1; {-2,0,2,4,6} Find the range of the function for the given domain.
Answer:
For the domain indicated, the range is {-11, -7, -3, 1, 5}
Step-by-step explanation:
Given the indicated domain of f(x) you have to replace the values in the function to find the range (the "y" values of the function).
f(-2) = 5
f(0) = 1
f(2) = -3
f(4) = -7
f(6) = -11.
So the range for this domain is {-11, -7, -3, 1, 5}
Hence, the range for this domain is [tex](5,1,-3,-7,-11)[/tex].
What is the function?
A function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.
Here given function is [tex]f(x)=2x+1;(-2,0,2,4,6)[/tex].
So,

N is less then 6 units from 0
What is the answer?
The answer would be negative 6 or -6.
Hope this helps!
The values for N can be any number between and including -6 and 6, because the phrase 'N is less than 6 units from 0' signifies absolute distance from zero on the number line.
Explanation:In mathematics, when we say 'N is less than 6 units from 0', we are referring to absolute distance from zero on the number line. That means, N could be any number that falls within the range of -6 to 6, inclusive. This is because the less than 6 units from zero is referring to both directions on the number line. For example, -4 is less than 6 units away from 0, also 5 is less than 6 units away from 0. Thus, the possible values for N are any numbers between and including -6 and 6.

Question
George invested $4400 in an account with annually compounded interest. After 5 years, he had $5790 in the account. What
was the interest rate of the account? Round your answer to one decimal place. Do not write the percent sign,
Answer:
The rate of interest was approx 5.64%.
Step-by-step explanation:
The compound interest formula is :
[tex]A=p(1+\frac{r}{n} )^{nt}[/tex]
Here p = 4400
r = ?
n = 1
t = 5
A = 5790
Now putting the values in formula we get;
[tex]5790=4400(1+\frac{r}{1} )^{5}[/tex]
=> [tex]5790=4400(1+r )^{5}[/tex]
=> [tex]\frac{5790}{4400} =(1+r )^{5}[/tex]
=> [tex]1.316=(1+r )^{5}[/tex]
=> [tex]1+r=\sqrt[5]{1.316}[/tex]
r = 0.0564
In percentage it is [tex]0.0564\times100[/tex] = 5.64%
Hence, the rate of interest was approx 5.64%.

The amount of rainfall each month over the past four years is shown below
Answer: C
Step-by-step explanation: On Edge 2020
D) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
What is Symmetrical Graph?A graph is said to be symmetric about a line if the graph remains unchanged when we reflect the graph on one side of the line to the other side.
Given is a histogram representing the amount of rainfall in the last 4 years or 48 months.
So the graph is symmetrical if we draw a line at the point 3.
Amount of rainfall is 0 - 1 inches for first 11 months. Then it is 1.01 - 2 inches for the next 8 months. Then 2.01 - 3 for the next 5 months and again 3.01 - 4 for the next 5 months. Then it is 4.01 - 5 and 5.01 - 6 for the next 8 years and 11 years respectively.
19 months has the rainfall less than 2.01 inches.
19 months has the rainfall greater than 4 inches.
Only 48 - (19 + 19) = 10 months are having rainfall in between 2.01 and 4.
So majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
Hence the correct option is D.

Why would a person choose a PPO over an HMO?
Answer:
With an HMO plan, you pick one primary care physician. All your health care services go through that doctor. That means that you need a referral before you can see any other health care professional, except in an emergency. Visits to health care professionals outside of your network typically aren’t covered by your insurance.
PPO plans give you flexibility. You don’t need a primary care physician. You can go to any health care professional you want without a referral inside or outside of your network.
Staying inside your network means smaller copays and full coverage. If you choose to go outside your network, you'll have higher out-of-pocket costs, and not all services may be covered.
This got me 100% on the assignment!
PPO plans give you flexibility. You don’t need a primary care physician. You can go to any health care professional you want without a referral inside or outside of your network.
Staying inside your network means smaller copays and full coverage.
HMO providers are paid on a per-member basis, regardless of the number of times they see a member.
This makes HMO plans a more economical choice than PPOs. An HMO generally only covers care received from the plan's contracted providers, known as “in-network” providers.
PPO plans generally are more expensive than HMO plans. However, due to the pooling of people in a PPO network, fees associated with health care will be lower for participants.
In other words, you will pay far less for services if you are in a PPO plan vs. not having insurance at all.
So, the person choose a PPO over a HMO.

* Lets explain how to solve the problem
- When we have a quantity we can divided it to many equivalent
fractions
- Equivalent fractions means fractions equal each other
- We can find the equivalent fraction by multiply or divide the two
terms of the fraction by the same number
- Ex: We can divide a circle into two equal parts each part is 1/2 the
circle, if we multiply each term of the fraction by 2 (up and down)
then we will have 2/4 which is equivalent to 1/2 the circle
- Then we can divide the circle by 2 parts with many equivalent fractions
1/2 = 2/4 = 3/6 = ..................
* Lets solve the problem
- Rafael wanted to order half a medium pizza
- The medium pizza could be cut into 6 or 8 slices
∵ The half of 6 is 3/6
∵ The half of 8 is 4/8
- Lets simplify the two fraction
∵ 3/6 = 1/2 by dividing up and down by 3
∵ 4/8 = 1/2 by dividing up and down by 4
∴ There is no difference between the two orders, both of them
equal half the pizza
∴ The wrong in Rafael reason is that 3/6 = 4/8 = 1/2 pizza

Answer:
m∠JNP=43°
m∠KNJ=94°
m∠KNL=43°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠JNP+m∠KNJ+m∠KNL=180° ----> by definition of supplementary angles
we have
m∠JNP=(2x+3)°
m∠KNJ=(3x+34)°
m∠KNL=(3x-17)°
substitute the values
(2x+3)°+(3x+34)°+(3x-17)°=180°
Combine like terms in the left side
(8x+20)=180
Subtract 20 both sides
8x=180-20
8x=160
x=20
Find the measure of m∠JNP
m∠JNP=(2x+3)°
substitute the value of x
m∠JNP=(2(20)+3)=43°
Find the measure of m∠KNJ
m∠KNJ=(3x+34)°
substitute the value of x
m∠KNJ=(3(20)+34)=94°
Find the measure of m∠KNL
m∠KNL=(3x-17)°
substitute the value of x
m∠KNL=(3(20)-17)=43°
