There is only 1 way to place the houses on the street.
If the contractor wishes to build 9 houses, each different in design, and there are 6 lots available on the street, there are 6 choose 9 (written as 6C9) ways to place these houses.
However, this number is not possible since 6C9 = 0,
which means there are no combinations of 6 elements taken 9 at a time.
A more appropriate calculation would be 6 choose 6 (written as 6C6), which represents the number of ways to place the 9 houses on the 6 available lots if each house must occupy a lot.
In this case, 6C6 = 1,

The area of a hexagon is equal to the sum of the areas of its 6 internal triangles.
Using the given measurements, what is the area, in square inches, of the regular hexagon shown above?
The area of the regular hexagon given in the figure is 360 inches²
What is the area of a triangle?The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. To find a triangle's area, use the formula area = 1/2 * base * height.
Given here: A hexagon with six triangles inscribed in it with height 10 inches and base 12 inches.
We know all the triangles must be congruent as we know that all of the sides are of equal length. Therefore, all 6 of the triangles (we get from drawing lines to opposite vertexes) are congruent triangles.
Thus area of the hexagon= 6×area of a triangle
A= 6×1/2×10×12
=360 inches²
Hence, The area of the regular hexagon given in the figure is 360 inches²

on a recent quiz, the class mean was 71 with a standard deviation of 4.2. calculate the z-score (to 4 decimal places) for a person who received score of 73.
The calculated value of z-score for the mean 71 and standard deviation 4.2 with person score 73 is equal to 0.4762( upto to four decimal place)
Mean of the data 'μ' = 71
Standard deviation of the data 'σ ' = 4.2
Score obtained by a person 'X' = 73
Formula for the z-score is equal to :
Z-score = ( X - μ ) / σ
Substitute the value of mean , standard deviation , and person score to get the value of z-score we have,
⇒ Z-score = ( 73 - 71 ) / 4.2
⇒ Z-score = ( 2 ) / 4.2
⇒ Z-score = 0.47619
⇒ Z-score = 0.4762
Therefore, the value of z-score as per the given mean and standard deviation is equal to 0.4762.

what is the effect of increasing sample size on the cost of collecting data and the quality of the data collected?
The relationship between sample size and data quality is likewise straightforward; the quality of the data will increase as the sample size increases and vice versa.
It is typically impossible, or at least impractical, to collect data from all of the subjects you are interested in when conducting research on your clients, patients, or products. Instead, we take a sample (or subset) of the relevant population and try to learn as much as we can about the population from that sample.
Numerous factors can impact how well our sample represents the population, and hence, how valid and dependable our results will be. In this blog post, we discuss some of the important ideas that should be taken into account while conducting a survey, such as power, effect sizes, and confidence intervals and margins of error.

define a positive integer n to be a factorial tail if there is some positive integer m such that the base-ten representation of m ! ends with exactly n zeros. how many positive integers less than 1992 are not factorial tails?
The number of positive integers which are less than 1992 and not factorial tails are 396.
Positive integer are defined as the all the integers greater then zero.There are positive integers, zero, and negative integers.
Let for some positive integer with exactly n zeros be m
Number at the end of zeros of m! be f(m)
f(m) = ( m /5 ) + ( m /25 ) + ( m /125 ) + ( m /625 ) + ....
Here 'm' is multiple of 5
So ,f(m) = f( m + 1) = f( m + 2) = f( m + 3 ) = f( m + 4 )
And f(m) ≤ ( m /5 ) + ( m /25 ) + ( m /125 ) + ( m /625 ) +...
= m / 4.03
= m / 4
Value of m greater than 7964 such that f(m) = 1991
f( 7975 ) = 1991
Number of distinct positive integer 7975 / 5 = 1595 less than 1992
Number of positive integers less than 1992 and they are not factorial tails are equal to

b) The greatest likelihood concept has a fault in that it ignores other accessible information, such as alternative probable occurrences and their effects.
What is maximum likelihood principle?The maximum likelihood principle is a strategy for determining the best values for the parameters that form a model. In doing so, you improve the possibility that your model will approach the "true" model. Maximum Likelihood Estimation (MLE) is a probabilistic strategy to determining model parameter values. Parameters may be thought of as blueprints for the model because they are the foundation upon which the algorithm operates. MLE is a popular approach in machine learning, time series analysis, panel data analysis, and discrete data analysis.

the company? What is the maximum profit
The constraints for the company are -
70<x<130, 50<y<110 and 150<x + y<220
The objective function for maximizing profit is z = 65x + 45y.
What are business constraints?
Constraints can be business or technical in nature and are defined as restrictions or limitations on possible solutions.
Considering that x is the number of laptops and y is the number of tablets.
According to the information provided, there are between 70 and 130 laptops.
Additionally, there are between 50 and 110 tablets.
Specifically, 70<x<130 and 50<y<110.
Between 150 and 220 devices make up the total number of x + y.
This equals 150<x + y<220.
These are all limitations on daily production.
Since each laptop makes $65 in profit and each tablet makes $45.
As a result, the overall profit for laptops is $65x and for tablets it is $45y.
Consequently, the objective function z for calculating total profit is -
z = 65x + 45y
Maximize z = 65x + 45y to make the most profit.

The total annual cost of the card to Sandra is $72.65
How to find the total annual cost of the card to Sandra?To find the total annual cost of the card to Sandra, we have to add all the money Sandra paid for the new credit card for the year. This can be calculated as follow:
Membership fee = $15
Balance transfer fee of 5% of $823.46 = 5/100 * $823.46 = $41.17
February $3.56; May, $5.82; July, $4.92; and September $2.18
