There is one outlier, indicating very few books were checked out on that day.
Answer: There is one outlier, indicating very few books were checked out on that day.
Step-by-step explanation:
The given data of he number of books checked out from a library during the first two weeks of the month:
36, 39, 40, 42, 45, 2, 38, 41, 37, 38, 35, 37, 35, 38
Here , all the data value are near to each other except one i.e. 2.
Since 2 is very small value as compare to the other data values.
It means 2 is the outlier for the data.
It means only 2 books were checked out on that day, which is much lesser number of books than the other day.
Hence, the statements is true based on the data set :
There is one outlier, indicating very few books were checked out on that day.

K is the midpoint of JL. If: JK = 5x + 1 and KL = 7x - 3. Find JL
Answers
To find JL, we simply add the lengths of JK and KL together which gives us 22 units.
If K is the midpoint of JL, it means that JK is equal in length to KL.
Thus, we can set up the equation 5x + 1 (for JK) equal to 7x - 3 (for KL) since these expressions represent the lengths of JK and KL respectively.
Solving the equation 5x + 1 = 7x - 3 for x, we find that x = 2. Substituting x back into the expression for either JK or KL yields the length of one segment, which in this case is 11 units for both JK and KL.

Aaliyah ate 7⁄8 of her mini-pizza, while James only ate 3⁄4 of his mini-pizza. How much more did Aaliyah eat
Answers
Final answer:
Aaliyah ate 1/8 more of the mini-pizza than James after converting their consumed amounts to a common denominator and subtracting James's share from Aaliyah's.
Explanation:
To calculate how much more Aaliyah ate compared to James, we need to compare the fractions of the mini-pizzas they each consumed. Aaliyah ate 7/8 of her mini-pizza, while James ate 3/4 of his mini-pizza. To make a comparison, we have to ensure both fractions have the same denominator.
Since the least common denominator for 4 and 8 is 8, we convert James's fraction from 3/4 to 6/8 by multiplying both the numerator and the denominator by 2. Now we can compare the amounts:
Aaliyah: 7/8 of a mini-pizza
James: 6/8 of a mini-pizza
To find out how much more Aaliyah ate, we subtract James's portion from Aaliyah's:
7/8 - 6/8 = 1/8
Therefore, Aaliyah ate 1/8 more of the mini-pizza than James.
The cunninghams are moving across the country. mr. cunningham leaves 3 hours before mrs. cunningham. if he averages 55mph and she averages 75mph, how long will it take mrs. cunningham to overtake mr. cunningham?
Answers
Mrs. Cunningham travels at a speed that is 20mph faster than Mr. Cunningham. Given that Mr. Cunningham has a 165-mile head start, Mrs. Cunningham would need 8.25 hours to cover this distance and catch up with him.
Explanation:This question can be approached by analysing the relative speeds and the initial advantage Mr. Cunningham had. Mr. Cunningham travels for three hours at 55 mph before Mrs. Cunningham leaves, giving him a 165 mile head start. To determine how long it will take Mrs. Cunningham to overtake Mr. Cunningham, it's necessary to calculate how long it will take her to make up this 165-mile deficit at her faster speed.
Mrs. Cunningham travels 75mph, which is 20mph faster than Mr. Cunningham's speed. Thus, each hour, she closes the distance between them by 20 miles. To find out how many hours it takes her to close the 165 mile distance between them, divide this distance by her relative speed, so: 165miles / 20mph equals 8.25 hours.
Thus, it will take Mrs. Cunningham 8.25 hours to overtake Mr. Cunningham.

what are the odds against rolling a sum of 6 with the roll of two dice?
Answers
Final answer:
The odds against rolling a sum of 6 with the roll of two dice are 31:5, as there are 5 favorable outcomes for a sum of 6 and 36 total possible outcomes when rolling two dice.
Explanation:
The question is asking about the odds against rolling a sum of 6 with two dice. To calculate this, first, we need to find all the possible combinations of two dice that sum up to 6. Those combinations are (1,5), (2,4), (3,3), (4,2), and (5,1), therefore there are 5 ways to achieve a sum of 6.
The total number of possible outcomes when rolling two dice is 6 * 6 = 36, since each die has 6 faces. So, there are 36 - 5 = 31 ways to not roll a sum of 6. The odds against rolling a sum of 6 are therefore the number of ways not to roll a 6 to the number of ways to roll a 6, which is 31:5.
Odds against rolling a sum of 6 with two dice = 31:5.
Write a recursive definition for the sequence 14, 10, 6, 2,… Common difference is 4 what do I do next?
Answers
a[n+1] = a[n] -4 . . . says each term is 4 less than the one before it
Since you're looking for a recursive definition, you simply need to do 2 things.
1. Define the function for some constant starting point(s).
2. Define the function in terms of itself for all other points.
For this question, I'll assume the first point is f(0). So we have f(x) = ?, with f(0) = 14
And we've handed the starting point by simply declaring that f(0) has the value of 14. Now for the recursive portion.
As you've noticed, each subsequent value is 4 less than the previous. So we can say f(x) = f(x-1) - 4. And with that, we can make the function.
f(x) = f(x-1) - 4, with f(0) = 14
As a side note, you are not restricted to just 1 starting value, nor just the immediate prior invocation of the function. For instance the definition of the Fibonacci sequence could be defined as
f(x) = f(x-1) + f(x-2), with f(0) = 0 and f(1) = 1

3.) Mattie must pay a $15 co-pay for each of her visits to a chiropractor. the insurance company pays 60% of the cost of the visit. After her accident, she made 12 visits to the chiropractor, each costing $305.
How much, in total, did Mattie pay for her chiropractor visits?
A.) $1464
B.) $1644
C.) $2196
D.) $2376
Answers
Answer:
B.) $307.60 ; C.) $252 ; B.) $1644
Step-by-step explanation:
1.) Since the employer pays 70% of the premium, this leaves Ms. Everett with 100-70=30% of the cost.
30% = 30/100 = 0.3; this makes her part of the cost
0.3(12304) = 3691.2
She gets paid monthly, so we divide this by 12:
3691.2/12 = 307.6
This means she has $307.60 deducted monthly.
2.) Since the insurance company pays 80% of the costs, this leaves Peter with 100-80 = 20% of the cost.
We take his deductible out of the cost first:
1060-50 = 1010
20% = 20/100 = 0.2; this makes his part of the cost
0.2(1010) = 202+50 = 252, since we have to count the deductible as part of his cost.
3.) The total cost of all visits would be
305(12) = 3660
The insurance company pays 60% of the cost; this means she is left with 100-60 = 40%. 40% = 40/100 = 0.4;
0.4(3660) = 1464
Mattie also pays 12 $15 copays; this adds 12(15) = 180 to this:
1464+180 = $1644
Ms. Everett's monthly deduction for her health insurance premium is $307.60. Peter paid $202 for his nutritional counseling after accounting for the deductible and insurance payment. Mattie paid a total of $1,644 for her chiropractor visits, considering the co-pays and her share of the visit costs after insurance.
Explanation:Calculating Health Insurance Contributions and Costs1. To determine the amount deducted from Ms. Everett's paycheck for her health insurance premium, we calculate 30% of the total annual premium (since her employer pays 70%) and then divide by 12 to get the monthly deduction.
Total annual premium: $12,304
Employer's share (70%): $12,304 × 0.70 = $8,612.80
Ms. Everett's share (30%): $12,304 × 0.30 = $3,691.20
Monthly deduction: $3,691.20 / 12 = $307.60
2. To find out how much Peter paid for his nutritional counseling, we subtract the $50 deductible from the total cost and then calculate 20% of the remaining amount (since the insurance pays 80%).
Total cost of counseling: $1,060
Deductible: $50
Amount after deductible: $1,060 - $50 = $1,010
Peter's share (20%): $1,010 × 0.20 = $202
3. To determine the total amount Mattie paid for her chiropractor visits, we multiply the co-pay by the number of visits and add to it the total amount of her share for the visits after insurance contribution.
Cost per visit: $305
Insurance pays (60%): $305 × 0.60 = $183
Mattie's share per visit (40%): $305 × 0.40 = $122
Co-pay per visit: $15
Total co-pay: $15 × 12 = $180
Total Mattie's share for visits: $122 × 12 = $1,464
Total amount Mattie paid: $1,464 + $180 = $1,644

Triangle PQR has two known interior angles of 24°, and 100°.
Triangle RST has two known interior angles of 24°, and 56°.
What can be determined about whether trianglesPQR and RST are similar?
Similarity cannot be determined from the given information.
The triangles are similar.
The triangles are not similar.
All interior angles must be given to determine similarity.
Answers
This is true of all triangles.
You have two given angles of triangle PQR.
They are 24 degree and 100 degree.
What do those measures add up to?
What is 100 + 24? = 124
When you add the measure of the third angle to 124, you must get 180.
To find the measure of the third angle, just do 180 - 124.
What do you get?
180 - 124 = 56
That means the third angle of triangle PQR measures 56 deg.
Now we know the measures of all three angles of triangle PQR: 24, 100, 56.
Triangle RST has two angles that measure 24 deg. and 56 deg.
Since two angles of triangle PQR are congruent to two angles of triangle RST, the triangles are similar.

We know that the opposite sides in a parallelogram are equal
so we have
PQ= SR= [tex]4\sqrt{2}[/tex]
PS= QR= [tex]\sqrt{10}[/tex]
Now to find the perimeter of parallelogram we add all the sides
perimeter = [tex]PQ+SR+PS+QR[/tex]

Answers
First let x = the dimension of the squares and y = the congruent sides of the isosceles triangles.
To get our first equation of the system, we look at the statement regarding the perimeter of DRAGONFLIES being equal to 127.. this implies the following equation: 9x + 2y = 127
To get the second equation, we need to know that the perimeter of an isosceles triangle is defined by: P = 2(length of the congruent sides) + base side. Or in our case, 55 = 2y + x
Now our system:
9x + 2y = 127
x + 2y = 55
You can use the substitution method or linear combination to solve this system. If you have questions about how to do that, let me know.
The solution of the system is: x = 9 and y = 23
Recall x = the dimension of each square, so the area of DRAG is 81
