Thus, the P-value = 0.1791
Interpret results. Since the P-value (0.1791) is greater than the significance level (0.05), we failed to reject the null hypothesis.
From the above test, we do not have sufficient evidence in favor of the claim that there is a difference in the mean occupancy rates.
Thus, option A is correct.

Show that the given set has a cardinality of X, by establishing a one-to-one correspondence between the elements of the given set and the elements of N. 1 1 1 ... 1 4. 16 64 1 41 Let N = 1, 2, 3,...,n,.. } 1 Then a one-to-one correspondence between the given set and the set of natural numbers N is given by the following general correspondence. 1)-
The cardinality of the given set is the same as the cardinality of the set of natural numbers, which is infinite.
To establish a one- to- one correspondence between the given set and the set of natural figures N, we need to find a rule or function that maps each element of the given set to a unique natural number.
The given set isn't explicitly defined, but we can interpret it as a sequence of figures. Let's examine the pattern in the sequence
1, 1, 1,., 1, 4, 16, 64, 1, 41,.
From the pattern, we can observe that the first several terms are each 1, followed by a 4, also a series of figures that feel unconnected to the former pattern. We need to find a rule that can collude each term of the given set to a unique natural number.
One possible way to establish a one- to- one correspondence is to assign natural figures in the following way
For the terms that are all 1, we can assign them the natural figures in thrusting order 1, 2, 3,.
For the term 4, we can assign it the coming natural number after the sequence of 1's 4 1 = 5.
For the term 16, we can assign it the coming natural number after 5 16 1 = 17.
For the term 64, we can assign it the coming natural number after 17 64 1 = 65.
For the term 1, we can assign it the coming natural number after 65 1 65 = 66.
For the term 41, we can assign it the coming natural number after 66 41 1 = 42.
This mapping establishes a one- to- one correspondence between the given set and the set of natural figuresN.

The sum of three consecutive odd integers is 75 . Find the value of the middle of the three.
The value of the middle of the three is 25.
Let x be the first odd integer, then the next two consecutive odd integers are x+2 and x+4. The sum of these three consecutive odd integers is given as 75, so we can write the equation:
x + (x+2) + (x+4) = 75
Simplifying the left side of this equation gives:
3x + 6 = 75
Subtracting 6 from both sides gives:
3x = 69
Dividing by 3 gives:
x = 23
So the first odd integer is 23, and the next two consecutive odd integers are 25 and 27. The middle of these three is the second consecutive odd integer, which is 25. Therefore, the value of the middle of the three is 25.

If a right circular cylinder and oblique cylinder both have a height of 12 inches and diameter of 6 inches, do they have the same volume? (Use straight pi equals 3.14)
Group of answer choices
Yes, they both have a volume of 339.12 inches cubed.
No, the right circular cylinder has a volume of 339.12 inches cubed and the oblique cylinder has a volume of 1 comma 356.48 inches cubed.
No, the right circular cylinder has a volume of 1 comma 356.48 inches cubedand the oblique cylinder has a volume of 339.12 inches cubed.
Yes, they both have a volume of 1 comma 356.48 inches cubed.
Answer:
Yes, they both have a volume of 339.12 inches cubed.
Step-by-step explanation:
To calculate the volume of an oblique cylinder is very simple, we must multiply π (Pi = ~ 3.14) by the radius to the power of two and then multiply by the height. In this case the height forms a 90 degree angle from the opposite base to the position of the base, but outside of it.
Volume = π × Radius² × Height
The formula for the volume of a regular cylinder or an oblique cylinder is the same, if we imagine a stack of poker chips (forming a cylinder), even when we tilt the chips to one side (forming an oblique cylinder) the volume remains the same.
Now using this information, we must find the volumes of both cylinders.
For the oblique cylinder:
Given
Using the formula,
The volume would be 339.29 m³
Now solving for the other cylinder:
V=πr²h=π·32·12≈339.29201
Rounded, the answer would be 33.29 m³
This therefore proves that they both have the same volume.

Identify the sampling technique used for the following study, A random number generator is used to choose five cities. Then a biologist collects data from each person in these cities Answer Tables Keypad Keyboard Shortcuts Census • Simple Random Sampling Stratified Sampling Cluster Sampling Systematic Sampling Convenience Sampling
The sampling technique used in the study described is Cluster Sampling. So, correct option is C.
Cluster Sampling involves dividing the population into groups, or clusters, and then randomly selecting clusters to include in the sample. In this case, the cities represent the clusters, and the biologist collected data from every person in each of the five selected cities.
This technique is different from Simple Random Sampling, which involves randomly selecting individuals from the population without grouping them, and Stratified Sampling, which involves dividing the population into subgroups and then selecting individuals from each subgroup.
Systematic Sampling involves selecting individuals from a list using a predetermined interval, and Convenience Sampling involves selecting individuals who are readily available and accessible.
Cluster Sampling is often used when the population is large and geographically dispersed, as it allows for a more efficient sampling process.
However, it can also increase sampling variability, as individuals within clusters may be more similar to each other than to individuals in other clusters. Therefore, it is important to ensure that the clusters are representative of the entire population to minimize bias.
So, correct option is C.

ok sooo If 9 were black and white them there were 5 for colored so you do 200/5 so you can figure out what to multiple with the black and white. So 200/5 = 40 then you do 9 * 40 = 360. Sorry if this does not make sense.
If in δ abc angle a is 50° and angle c is 75°, which triangle is similar to δ abc?.
The triangle similar to triangle ABC will be the triangle with the corresponding angles as same as 50°, 75°, 55°.
What is triangle?
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle ABC in which angle [A] is 50° and angle [C] is 75°
The third angle of the triangle would be -
A + B + C = 180
50 + 75 + C = 180
C = 180 - 125
C = 55°
The triangle similar to triangle ABC will be the triangle with the corresponding angles as same as 50°, 75°, 55°.
Therefore, the triangle similar to triangle ABC will be the triangle with the corresponding angles as same as 50°, 75°, 55°.

How do u Mulitply a Coefficient
Answer:
To multiply terms, multiply the coefficients and add the exponents on each variable. The number of terms in the product will be equal to the product of the number of terms.
Step-by-step explanation:
For example, 3 is the coefficient in 3x. Rather than using a multiplication sign between 3 and x, the number is just written in front of a variable, which means that the 3 and x are multiplied together. Instead of writing a + a + a + a, you can express it as 4a, with 4 being the coefficient.
