The standard deviation is 4.0, while mean is 10.2.
What is standard deviation?Data dispersion in regard to the mean is quantified by a standard deviation, or. Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.
Mean = 10.2
The standard deviation is 4.0.
Age in the mean is the average age.
Mean = (16 + 10 + 5 + 7 + 13)/5

The limit of f(x) as x approaches 0 is 1.
The limit of f of x as x approaches 0 can be calculated using limit theorems. First, we rewrite the function as:
f(x) = (x + 1) / (1 / (x - 1))
Then, we can simplify this by multiplying both the numerator and denominator by (x - 1):
f(x) = (x + 1)(x - 1) / 1
Next, we can apply the limit theorem that states the limit of a product is the product of the limits. Thus, we can calculate the limit as:
lim f(x) = lim (x + 1)(x - 1) / 1
= lim (x + 1) * lim (x - 1) / 1
= 0 + 1 * 0 - 1 / 1

the sampling distribution of the sample mean based on samples of size 2 for the population was simulated, and a histogram of the results was produced. whifh of the following histograms is most likely the histogram of the sampling distribution
The sampling distribution of the sample mean based on samples of size 2 for a population can be approximated by a normal distribution.
The histogram of the sampling distribution would therefore look like a bell-shaped curve. The mean of the sampling distribution is equal to the population mean, and the standard deviation of the sampling distribution is equal to the population standard deviation divided by the square root of the sample size (in this case, 2).
Therefore, the formula for the sampling distribution of the sample mean for a population of size 2 is:
Mean = Population Mean
Standard Deviation = Population Standard Deviation / √2
The histogram of the sampling distribution would look like a bell-shaped curve with the mean and standard deviation determined by the formula above.

a) Calculate the model that would explain the utility that could be obtained.
b) Determine the number of workers that would originate the maximum benefit for the collaborators. How much is this utility?
c) Represent the income function graphically, obtain the maximum income and interpret it.
The model that would explain the utility is U(q) = - 0.02q^2 - 300 + 10q.
The maximum number of workers is 250 and utility is 950
The model that would explain the utilityFrom the question, we have the following parameters that can be used in our computation:
The total income as I(q) = 60q - 0.02q^2.
The total cost as C(q) = 300 + 50q.
The utility model can then be calculated as
U(q) = I(q) - C(q)
So, we have
U(q) = 60q - 0.02q^2 - 300 - 50q.
U(q) = - 0.02q^2 - 300 + 10q.
The maximum number of workers and utilityWe have
U(q) = - 0.02q^2 - 300 + 10q.
Differentiate and set to 0
-0.04q + 10 = 0
So, we have
-0.04q = -10
This gives
q = 250 --- max workers
Recall that
U(q) = - 0.02q^2 - 300 + 10q.
So, we have
U(250) = - 0.02* 250^2 - 300 + 10 * 250
U(250) = 950 --- amount of utility

Answer:
12x^4y^7
Step-by-step explanation:
base(b)=8x^3y^5
height(h) =3xy^2
Area= (b x h)/2 =12x^4y^7
Answer:
[tex]A = 12x^4y^7[/tex]
Step-by-step explanation:
The formula for the area of a triangle is:
[tex]A = \dfrac{1}{2}bh[/tex]
where [tex]b[/tex] is the length of the triangle's base and [tex]h[/tex] is the length of the triangle's height.
In this problem, we are given the length of the base of the triangle as [tex]8x^3y^5[/tex] and the length of the height of the triangle as [tex]3xy^2[/tex].
Thus, the area of the given triangle is:
[tex]A = \dfrac{1}{2} \cdot 8x^3y^5 \cdot 3xy^2[/tex]
We can simplify this by combining like terms and using the exponent addition rule ([tex]x^a \cdot x^b = x^{a+b}[/tex]).
[tex]A =\left(\dfrac{1}{2} \cdot 8 \cdot 3 \right)(x^3 \cdot x)(y^5 \cdot y^2)[/tex]
[tex]A = (4 \cdot 3)(x^{3 + 1})(y^{5+2})[/tex]
[tex]A = 12x^4y^7[/tex]
a new restaurant is interested in determining the best time-temperature combination for roasting a five-pound cut of lamb. the times to be tested are 45 minutes, 60 minutes, and 90 minutes at temperatures of 350 degrees fahrenheit and 425 degrees fahrenheit for each time, with the exception of the 90 minute - 425 degree combination. that combination is being eliminated because it will overcook the lamb, which leaves five combinations remaining. from 10 identical cuts of lamb, 2 are randomly selected to roast using each of the time-temperature combinations in the same oven. the quality of the finished product is evaluated for each roast. which of the following is true?
The two cuts that are being roasted for each time-temperature combination are an example of replication.
Option (c) is correct.
What is temperature?
Temperature is a measure of the average thermal energy of the particles in a substance. It is a scalar quantity, meaning it has only a magnitude and not a direction. The most commonly used unit of temperature measurement is the degree Celsius (°C) or the degree Fahrenheit (°F), but it can also be measured in Kelvin (K) in scientific and engineering applications.
Given options are:
(a) The two cuts that are being roasted for each time-temperature combination are an example of conduction
(b) The two cuts that are being roasted for each time-temperature combination are an example of convection
(c) The two cuts that are being roasted for each time-temperature combination are an example of replication
(d) None of the above
(c) The two cuts that are being roasted for each time-temperature combination are an example of replication.
In the question it is given that From 10 identical cuts of lamb, 2 are randomly selected to roast using each of the time-temperature combinations in the same oven. Here it is an act of copying the exact sahpe size of the lamb in all cuts, which is nothing but replication. Moreover, this replication can help in proper comparision.
Hence, The two cuts that are being roasted for each time-temperature combination are an example of replication.

Pat is the CEO of Pat's Pickle-Packing Plant, but can still pack 18 jars of pickles per hour. Kim, a rising star in the industry, packs 24 jars per hour. Kim arrived at work at 9:00 am one day to find that Pat had been packing pickles since
7:30 am. Later that day, Kim had packed exactly the same number of jars as Pat. At what time, and how many jars had each packed?
Using the equation
Pat picked for 6 hours, Kim picked for 4.5 hours and they both picked 108 jars.How to find the time and number of jars picked?Since Pat is the CEO of Pat's Pickle-Packing Plant, but can still pack 18 jars of pickles per hour. Kim, a rising star in the industry, packs 24 jars per hour. Kim arrived at work at 9:00 am one day to find that Pat had been packing pickles since
7:30 am. Later that day, Kim had packed exactly the same number of jars as Pat.To find the time and number of jars picked, we solve an equation.
What is an equation?An equation is a mathematical expression that shows the relationship between two variables.
Let
t = time Pat starts,n = number of jars of pickles picked by Pat and n' = number of jars of pickles picked by KimSince Pat picks at a rate of 18 jars of pickles per hour, the number of jars Pat picks is n = 18t
Also, Kim picks at a rate of 24 jars per hour, 1.5 hours later the number of jars Kim picks is n' = 24(t + 1.5)
Since n = n', we have that
18t = 24(t - 1.5)
18t = 24t - 36
18t - 24t = -36
-6t = -36
t = -36/-6
t = 6 hours
Since Kim's time is t - 1.5 = 6 - 1.5 = 4.5 hours
To find the number of jars each picked, substitute t = 6 into n. so, we have that
n = 18t
= 18(6)
= 108 jars
So,
Pat picked for 6 hours, Kim picked for 4.5 hours and they both picked 108 jars.Learn more about equation here:

Jennifer opened a savings account and deposited $300.00. The account earns 13% interest, compounded monthly. If she wants to use the money to buy a new bicycle in 2 years, how much will she be able to spend on the bike?
If Jennifer wants to use the money to buy a new bicycle in 2 years, she can spend (future value) $388.54 on the bike as the account earns 13% interest, compounded monthly.
What is compounded interest?Compound interest is a system of interest computation where interest accumulates on the principal and previously accumulated interests.
Compounding the present value means adding interest to the principal amount when calculating subsequent interests.
N (# of periods) = 24 months (2 years x 12)
I/Y (Interest per year) = 13%
PV (Present Value) = $300
PMT (Periodic Payment) = $0
Results:
Future Value (F) = $388.54
Total Interest = $88.54
Thus, with a deposit of $300, Jennifer can spend $388.54 after earning 13% monthly compounded interest.
