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
= 1991 - 1595
= 396.
Therefore, there are 396 positive integers which are less than 1992 and are not factorial tails.

In scientific notation??
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.

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
Total annual cost = $15 + $41.17 + $3.56 + $5.82 + $4.92 + $2.18 = $72.65

What do you put on the X axis of an ogive?
The X-axis (horizontal axis) often represents a "class boundaries" of such an ogive, whereas the Y-axis (vertical axis) typically shows the frequency count.
Explain about the ogive graph?A sort of frequency polygon that displays cumulative frequencies is an ogive, often known as a cumulative frequency polygon.
In other words, the graph adds the cumulative percents from left to right.On an ogive graph, "class boundaries" are shown along the x-axis while cumulative frequency is shown on the y-axis. Comparable to a histogram, an ogive features a single point that indicates in which the top right corner of the rectangular would be located in place of rectangles. This type of graph is typically simpler to make from such a frequency table.Thus, The X-axis (horizontal axis) often represents a class boundaries being measured of such an ogive.

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.

1.07 x 10^4 m^3
2.54 x 10^10 m^3
4.51 x 10^10 m^3
A spherical astroid has a radius of approximately 8.5 x 10^2 m. Using the formula 4/3 π r^3 to find the approximate volume of the asteroid, we get volume = 2.57 x 10^9 m^3.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
a spherical astroid has a radius of approximately 8.5 x 10^2 m.
we know,
the volume = 4/3 π r^3
so, by calculating, we get.
volume = 2.57 x 10^9 m^3
Hence, a spherical astroid has a radius of approximately 8.5 x 10^2 m. Using the formula 4/3 π r^3 to find the approximate volume of the asteroid, we get volume = 2.57 x 10^9 m^3.
