Describe a method that could be used to select a random sample of size 150 from the intended population. Be as detailed as you can, and pretend you are explaining this to someone with no statistical experience. c. What is the sample for this study
Answers
Answer:
a.) Citizens of Deerfield Township who have the right to vote.
B.) Stratified Random Sampling
C.) The citizens in each strata, 150 voters
Step-by-step explanation:
Deership Citizens who have voting right.
B.)
Stratified Random sampling : A random selection of voters based on criteria such as Dividing the whole township into districts and then random samples of voters is chosen from each district. For instance, if there are 15 different districts, a random sample of 10 voters is chosen from each district.
15 * 10 = 150
C.) The sample refers to a subset of the population which when chosen at random is representative of the larger population. The sample in the study are the voters in each strata.
the curve of a normal distribution extends indefinitely at the tails but does not
Answers
Answer:
But does not touch the horizontal axis.
Step-by-step explanation:
The curve of a normal distribution extends indefinitely at the tails but does not " touch the horizontal axis."
The reason for this is that the tails of the curve suggest that a variable can take on any theoretically reasonable value, although the probability of such occurrence is considerably low.
Generally, a normal distribution curve is considered to be asymptotic to the horizontal axis.
In this exercise we have to have knowledge about distribution and complete the sentence, thus we find:
The curve of a normal distribution extends indefinitely at the tails but does not but does not touch the horizontal axis.
What is a normal distribution ?The great utility of this distribution is associated with the fact that it quite satisfactorily approximates the frequency curves of physical measurements, this curve is known as the normal or gaussine distribution.
Returning to the exercise we have to:
That when we deal with a normal distribution we will have that the tail will not touch the horizontal axis since that way it would mean that it reached zero.

Answers
Answer:
The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

HURRY PLEASE! AT LEAST ONE PARAGRAPH! Describe in words how to find the surface area of a cylinder if the radius is 5cm and
height is 18cm.
Answers
Answer:
722.57cm²
Step-by-step explanation:
Below, we have listed six basic equations that can be used to derive the explicit formulas of radius of a cylinder:
Volume of a cylinder: V = π * r² * h ,
Base surface area of a cylinder: A_b = 2 * π * r² ,
Lateral surface area of a cylinder: A_l = 2 * π * r * h ,
Total surface area of a cylinder: A = A_b + A_l ,
Surface Area of Cylinders. To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.

Answers
Answer:
Roberto can buy 7 videogames.
Step-by-step explanation:
Given that Roberto has $ 200 in spending money and he wants to buy some video games that cost $ 25.50 each, to determine the number of games he can buy, the following inequality must be resolved:
25.50X = 200
X = 200 / 25.50
X = 7.84
Thus, since the whole number is 7, with $ 200 you can buy 7 video games, and there will be $ 21.5 (200 - 178.5) left over.

HELP ITS REALLY URGENT
Answers
Answer/Step-by-step explanation:
a. m<h = x°
Two angles to use in finding x are <h and 55°
Angle pair formed: linear pair angles
b. x° + 55° = 180° (linear pair)
Subtract 55° from each side
x + 55 - 55 = 180 - 55
x = 125°
c. Given: m<n = y°
Two angles to use in solving for y are: <h and <n
Angle pair formed: alternate exterior angles
d. m<n = y° (given)
m<n = x° = 125° (as solved in 2b)
Therefore:
y = x (alternate exterior angles are congruent)
thus:
y = 125° (substitution)

Select the correct answer. A sample of a certain type of bacteria is enclosed in a glass container on March 1st. The sample of bacteria starts to grow and cover the bottom surface of the container in such a way that the area covered by the bacteria doubles every day. If it continues to grow in this way, the bottom surface of the glass container will be entirely covered with the bacteria on March 10th. When will a quarter of the bottom surface of the glass container be covered? The bottom surface of the glass container will be covered a quarter of the way on March 9th. The bottom surface of the glass container will be covered a quarter of the way on March 6th. The bottom surface of the glass container will be covered a quarter of the way on March 7th. The bottom surface of the glass container will be covered a quarter of the way on March 8th.
Answers
Answer:
The bottom surface of the glass container will be covered a quarter of the way on March 8th.
Step-by-step explanation:
The bacteria covering the bottom surface of the glass container doubles every day. If the surface is completely covered on March 10th, then one day earlier, on March 9th, half of the surface is covered.
Similarly, if half of the surface is covered on March 9th, then one day earlier, on March 8th, a quarter of the surface is covered.
Therefore, the bottom surface of the glass container will be covered a quarter of the way on March 8th.
The bottom surface of the glass container will be covered a quarter of the way on March 8th.
What is an exponential function?The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = b^x is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.
The microorganism protecting the lowest floor of the glass box doubles each day. If the floor is absolutely protected on March 10th, then in the future earlier, on March 9th, 1/2 of the floor is protected.
Similarly, if 1/2 of the floor is protected on March 9th, then in the future earlier, on March 8th, 1 / 4 of the floor is protected. Therefore, the lowest floor of the glass box can be protected 1 / 4 of the manner on March 8th.
Therefore, the bottom surface of the glass container will be covered a quarter of the way on March 8th.
