Consider two population distributions labeled A and B. Distribution A is highly skewed and nonnormal, while distribution B is slightly skewed and near normal. In order for the sampling distributions of A and B to achieve the same degree of normality: A. Population A will require a larger sample size. B. Population B will require a larger sample size. C. Populations A and B will require the same sample size. D. None of these.
Answer:
A. Population A will require a larger sample size.
Step-by-step explanation:
A highly skewed distribution shows that too much data is concentrated where it is highly skewed.
If the sample size in increased the data may not concentrate at the same point and the skewness is normal that is it is mesokurtic.
The normal curve called the mesokurtic is neither very peaked nor very flat topped.
Populations A and B cannot have the same sample size as there is difference in their skewness.
Therefore option C and D are incorrect.
Option B is also incorrect because if B will require a larger sample size then the skewness may almost finish and the data may have the same concentration at all points.It will become flat topped i.e platy kurtic.
So only option A is correct.
In creasing the sample size will make the curve normal and mesokurtic.
Does the following equation, y= -x2 -10x +1 have a maximum or
minimum. Explain
Answer:
Step-by-step explanation:
Your y= -x2 -10x +1 should be written as y = -x^2 -10x +1. This is a quadratic function. Because the coefficient (-1) of the x^2 term is negative, we know immediately that the graph (a parabola) opens down, and thus has a maximum.

Answer:
150 yd
Step-by-step explanation:
Since the line segment is an angle bisector then it divides the opposite side into segments that are proportional to the other 2 sides , that is
[tex]\frac{250}{375}[/tex] = [tex]\frac{x}{225}[/tex] ( x is the distance from the hole to the oak tree )
Cross- multiply
375x = 56250 ( divide both sides by 375 )
x = 150
The hole is 150 yards from the oak tree.
He exponential model describes the population, A, of a country in millions, t years after 2003. Use the model to determine the population of the country in 2003. The population of the country in 2003 was nothing million.
Complete question :
The exponential model A=16.2e^0.01t describes the population, A, of a country in millions, t years after 2003. What was the population in 2003?
Answer:
16.2 million
Step-by-step explanation:
Given the equation :
A=16.2e^0.01^t
Where, t = number of years after 2003
The population in year 2003 ; can be obtained thus ;
t = 2003 - 2003 = 0
Put t = 0 in the equation :
A(0) =16.2e^0.01^0
A(0) = 16.2 * 1
A(0) = 16.2
Hence, population in 2003 is 16.2 million
The quotient property of radicals requires the indices of the radicals to be the same. Does this mean that it is not possible to write 4Vy^3/Vy as a single radical? Explain.

Which piecewise function is shown on the graph?
Answer:
Option A
Step-by-step explanation:
Just substitute each value of x in the graph to find the correct function.
When be graph the functions given, we find that option A is correct.
What is meant by to graph a function?To graph a function, you have to select x-values and plug them into the equation. Once you plug those values into the equation, you will get a y-value. Your x-values and your y-values make up your coordinates for a single point. Keep plugging in x-values to get coordinates to plot more points on the graph, and then you will see your graphed function once the dots are connected.
Using the graph,
For x < = -2, y = 5.
For -2 < x < 1, the function is a polynomial.
We have two options, either [tex]y = x^{2} -5\ or\ y = x^{2} +5[/tex]
The polynomial must have the point (0,-5) on it.
For [tex]y = x^{2} -5[/tex] , when x = 0, y = -5.
Hence, it is the correct option.
For x >= 1,
Using graph, we see that when y = 0, x lies between 3 and 4.
For equation, [tex]y = 2^{(x-2)} - 2\\[/tex], when y = 0, x = 3, so it is not correct.
For equation, [tex]y = 2^{(x-2)} - 3\\[/tex], when y = 0, x = 3.584, hence it is correct.

A. n = 12
B. n = -12
C. n = -3
D. n = 3
Answer:
n/3+2 =-2
n+6=-6
n=-12 is your answer
Answer:
B
Step-by-step explanation:
Given
[tex]\frac{n}{3}[/tex] + 2 = - 2 ( subtract 2 from both sides )
[tex]\frac{n}{3}[/tex] = - 4 ( multiply both sides by 3 to clear the fraction )
n = - 12 → B
The probability that a randomly selected student is on honor roll is 0.24 The probability that a randomly selected student is on the honor roll and takes an art class is 0.18 what is the probability that a randomly selected student takes an art class, given the student is on honor roll
Answer: 0.06
Step-by-step explanation: subtract them and you'll get your answer
The probability that a randomly selected student takes an art class, given the student is on honor roll is P ( A|B ) = 0.75
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
The conditional probability is given by
P(A|B) = P(A and B) / P(B)
where A and B are events.
In this case, let A be the event that a randomly selected student takes an art class, and let B be the event that the student is on honor roll.
The probability that a selected student is on honor roll P ( B ) = 0.24
The probability that a selected student is on honor roll and takes an art class P (A and B) = 0.18
Now , the probability that a randomly selected student takes an art class, given the student is on honor roll P(A|B) = P(A and B) / P(B)
P(A|B) = P(A and B) / P(B) = 0.18 / 0.24 = 0.75
Hence , the probability is 0.75 or 75%

If tara invites 6 friends. And each friend should get 5 cookies but there are 12 cookies how many more cookies does tara need.
Answer:
18
Step-by-step explanation:
6 friends times 5 cookies is 30 cookies in total
30 cookies minus 12 cookies already made is 18!
Answer: 18 cookies
Step-by-step explanation:
Tara invites 6 friends, each friend gets 5 cookies.
So, 6 x 5 to find how many cookies are for 6 friends.
6 x 5
= 30 cookies
Tara only has 12 cookies. How much more does she need?
Everyone should get 30 cookies, but there is only 12.
Subtract to find the difference!
30-12=18
