quotient, and Jorge disagrees. Who is right? Explain your answer
Answer:
Nathan

an insurance company wants to study whether offering incentives for preventative care reduces overall health care costs. they select a random sample of 200200200 of their customers. they use a random number generator to select 100100100 customer account numbers to offer the incentive. the remaining 100100100 customers are assigned to the control group. what type of experiment design is this?
Using the concepts of probability, we got that that Stratified sampling is the experiment design which an insurance company which wants to study whether offering incentives for preventative care reduces overall health care costs.
In the question, actually the insurance company intends to study and understand the relationship between the health care cost of the customers and the provision of incentives for the preventative care by two groups, each having one of two given attributes under study, which are;
a) One group consist of the customers having high health care cost and offered incentives for preventative care
b) The other group consist of the customers having only high health care cost without incentives
Therefore, the insurance company customers are stratified into the groups based on health care cost and again into the groups that have high health care cost and are offered preventative care and those that have only the high heath care cost, which is the process used to implement the stratified sampling technique.
Hence, an insurance company which wants to study whether offering incentives for preventative care reduces overall health care costs, by selecting a random sample of 200200200 of their customers and using a random number generator to select 100100100 customer account numbers to offer the incentive, the experiment design is named as Stratified sampling.

the simple interest formula is i = prt where i = the interest p=the principal r is the annual interest rate in the decimal form and t is the time in years. find the simple interest earned for a principal of 2,000 at an 8% interest the ate for 5 years.
The simple interest earned on a 2,000 principal at 8% interest for 5 years is I = $1,937.50.
What is meant by simple interest formula?Simple interest is calculated by multiplying the daily interest rate by the principal and the number of days between payments. Customers who pay their loans on time or early each month save money on interest.Interest-only loans are prevalent for short-term personal loans and car loans. Simply multiply the principal amount by the interest rate and the time to determine simple interest.The written formula is "Simple Interest = Principal x Interest Rate x Time." Simple interest is calculated on the loan principal or the first deposit into a savings account.Due to the fact that simple interest does not compound, a creditor will only pay interest on the principal amount, and a borrower will never be required to pay interest on previously accumulated interest.Therefore,
I = Prt
First, converting R percent to r a decimal
r = R/100 = 3.875%/100 = 0.03875 per year,
then, solving our equation
I = 10000 × 0.03875 × 5 = 1937.5
I = $ 1,937.50

a rancher has 200 feet of fencing with which to enclose two adjacent rectangular corrals (see figure). what dimensions should be used so that the enclosed area will be a maximum?
The dimension of each corral should be 25 feet in width and 33⅓ feet in length so that the enclosed area will be a maximum.
Adjacent rectengular corral has length and width with area formula as below.
A = L × W
Given:
The dimension of adjacent rectangular corrals are the same.Adjacent side = 200 feet.Because the dimension of adjacent rectangular corrals are the same, so:
W = 4x
L = 3y
3y + 4x = 200
[tex]y = \frac{200 - 4x}{3} [/tex]
There are two adjacent rectangular corrals, so:
A = 2×L×W
[tex]A = 2 \times \frac{200 - 4x}{3} \times \: x [/tex]
A = ⅓(400x–8x²)
We can differentiate to get the maximum area:
⅓×(400x–8x²) = 0
400–16x = 0
16x = 400
x = 25 feet
Substitute x value (width) to get y value (length):
y = (200–4(25)) ÷ 3
y = (200–100) ÷ 3
y = 100 ÷ 3
y = 33⅓ feet

Use three unit multipliers to convert 5280ft to meters
The three-unit multipliers are follows, 5280ft × 12 inches × 2.54 cm × 0.01 meter and it will be 1609.344 meters.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
As per the given,5280ft
It is known that 1 ft = 12 inches.
5280ft = 5280 x 12 inches
It is known that 1 inch = 2.54 cm
5280 x 12 inches = 5280 x 12 x 2.54 cm
It is known that 1 cm = 0.01 meter
5280 x 12 x 2.54 cm = 5280 x 12 x 2.54 x 0.01 meter
⇒ 1609.344 meters
Hence "The three-unit multipliers are as follows, 5280ft × 12 inches × 2.54 cm × 0.01 meter and it will be 1609.344 meters".

The width, labelled x in the figure is 162.5 meters
How to determine the width of the rectangle?From the question, we have the following parameters that can be used in our computation:
Length = 650 - 2x
Width = x
The area of a rectangle is the product of its dimensions
So, we have
Area = Length x Width
Substitute the known values in the above equation, so, we have the following representation
A = (650 - 2x) * x
Evaluate
A = 650x - 2x²
Differentiate and set to 0
650 - 4x = 0

In the translation T of the graph below, use the figure to describe the following transformation.
The translation T due to the transformation is (5,3)
How to describe the transformation using the figure?Translation can be defined as movement in a straight line
Given the rule: (x,y) → (x + 3, y + 1) as seen in the image. That means (x,y) translated to (x + 3, y + 1). This is what we use to solve this problem.
From the figure, the value of (x, y) can be read i.e. (x, y) = (2,2)
Thus the translation will be:
(x,y) → (x + 3, y + 1)
(2,2) → (2 + 3, 2 + 1) = (5, 3)

sara has 20 sweets
12 liquorice sweets , 5 mint sweets and 3 humbugs.
sara takes two random sweets
work out probability that the two sweets will not be the same
If sara takes two random sweets. The probability that the two sweets will not be the same is :111/190.
How to find the probability?Probability of getting two of each sweet:
P( Liquorice) = (12/20)×(11/19)
P (Liquorice) =132/380
P (mints) =(5/20)×(4/19)
P (mints) =20/380
P (Humbugs) =(3/20)×(2/19)
P (Humbugs) =6/380
Probability that two sweets will be the same
P(same) =132/380+20/380+6/380
P(same) =158/380
Hence,
Probability that two sweets will not be the same
P(not same) = 1- (158/380)
P(not same) =380 -158 /380
P(not same) = 222 /380
