The paper's smallest dimensions are height=8.660in and width=17.321in.
What are dimensions?In physics and mathematics, the dimension of space is the smallest set of coordinates needed to specify any point within a mathematical space.
A line has a dimension of one because only one coordinate is needed to specify a point on a line, such as a point at 5 on a number.
So, we have:
Area = 150in²
Side margin = 1 in
Top and Bottom Margin = 2 in
To obtain the smallest dimensions, calculate as follows:
The printed material's area is:
Area = l*w
A1 = h*w
A1 should be changed to 150:
150 = h*w
h = 150/w
The complete paper's topic is:
Area = l*w
A2 = (w+2+2)*(H+1+1)
A2 = (w+4)*(H+2)
For H, substitute 150/W:
A2 = (w+4)*(150/w+2)
A2 = w(150/w+2) + 4(150/w+2)
A2 = 150 + 2w + 600w + 8
A2 = 2w = 600/w + 8 + 150
A2 = 2w = 600/w + 158
Calculate a difference with regard to w and set the outcome to 0:
A'2 = 2-600/w²+0
A'2 = 2-600/w²
0 = 2 - 600/w²
2 = 600/w²
2*w² = 600
w² = 600/2
w² = 300
w = 17.321
Remember that:
h = 150/w
h = 150/17.321
h = 8.660
Therefore, the paper's smallest dimensions are height=8.660in and width=17.321in.

Describe the term percentage of the number?A value or ratio that might be stated as a fraction over 100 is thought to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its total and then multiply it by 100. The proportion ultimately refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.For the stated question-
Let initial enrollment = 100.
After one decade, the enrollment added 30% of the initial.
Thus,

what is the minimum number of cards you would have to pull from a deck to guarantee that you have 4 of a kind? (answer: 40)
The probability that a deck to guarantee that you have 4 of a kind is 40.
Probability:
In math probability refers the possibility of event.
Given,
Here we need to find the minimum number of cards you would have to pull from a deck to guarantee that you have 4 of a kind.
As we know that the total number of cards in the deck is 52.
So, the number of ways of choosing 4 cards from a pack of 52 playing cards is calculated as,
=> ⁵²C₄ = 52!/4!48!

a hand of 13 cards is dealt at random from a bridge deck of 52 cards. find the probability that the hand contains 4 queens. (round your answer to four decimal places.)
The probability of the hand containing 4 queens when picked at random is 0.0026.
We can solve the given question easily using probability, permutations, and combinations.

Estimate the true proportion of adults who would like to travel to outer space with 88% accuracy. Round your answers to at least three decimal places.
The true proportion of adults is in the interval 0.4026< P< 0.4594.
Here we have to estimate the true population of adults who would like to travel to outer space with 88% accuracy.
Data provided:
selected (x) = 329
Total(n) = 763
Sample proportion (p') = x/n
= 329/ 763
= 0.431
Critical z-value = 1.59
margin of error(E) = z[tex]\sqrt{p'( 1-p')/n}[/tex]
= 1.59 [tex]\sqrt{0.431(1-0.431) / 763}[/tex]
= 1.59 × 0.0179

88% confidence interval is:
(p' ± E) = ( 0.431 ± 0.0284)

A researcher is interested in whether using your finger to follow the words you are reading changes reading speed. He has students complete a reading speed test, first without using their fingers to follow the words and then again while using their fingers to follow the words. The researcher randomly selects a sample of 56 students who, at the beginning of the study, scored an average of 256 words per minute on the reading speed test. In the trial where they used their fingers while they read, the students scored an average of 6 words per minute higher. The standard deviation of the difference scores was 29. Since the sample size is larger than 30, the researcher can assume that the sampling distribution of MD is normal. He uses a repeated-measures t test to test that the mean difference is zero, and he describes the results as follows: In the trial where they used their fingers while they read, the reading speed among students is not significantly different than when they do not use their fingers while they read, t(55) = 1.55, p = 0.127. If the researcher had used a repeated-measures ANOVA to test that the mean reading speed is the same before and after using their fingers while they read, he would describe the results as follows (fill in all missing values): In the trial where they used their fingers while they read, the reading speed among students is different than when they do not use their fingers while they read, F()=, p = 0.127.
The confidence interval for the given ANOVA test to calculate the average typing speed be, (144.83 , 155.17) and the margin of error of the poll be, ±5.17
On Subtracting 1 from your sample size, we get
150 – 1 = 149.
On Subtracting confidence level from 1, and then divide by two.
(1 – .95) / 2 = 0.025
Now, df = 149 and α = 0.025
from the table at df = 149 we got 2.262.
Divide your sample standard deviation by the square root of your sample size.
28 / √(150) = 2.28
Now, 2.262 × 2.28 = 5.17
So, the confidence interval be,
(150 - 5.17 , 150 + 5.17) = (144.83 , 155.17)
Hence, the confidence interval for the given ANOVA test to calculate the average typing speed be, (144.83 , 155.17) and the margin of error of the poll be, ±5.17

The mathematical way to describe an interaction is: A difference in differences.
What is an interaction?In statistics, an interaction may appear when analyzing the relationship between three or more variables, and defines a situation in which the effect of one causal variable on an outcome forms on the state of a second causal variable.
Interactions are often considered in the context of regression analyses or factorial experiments. An interaction happens when an independent variable has a different effect on the outcome depending on the values of another independent variable.
To find an interaction, we need a factorial design, in which the two (or more) independent variables are crossed with one another, so there are reflections at every combination of levels of the two independent variables.

Given that,
One day, a teacher of statistics randomly selected 10 pupils' names from a hat and instructed them to complete as many pushups as they could before class began. The 10 students who were chosen at random performed an average of 15 pushups, with a standard deviation of 9. Assume that the population's distribution of the maximum number of pushups is roughly normal.
We have to find what is the standard error of the mean.
We know that,
For this problem, we have the standard deviation for the sample, thus, the t-distribution is used.
The sample mean is of 15 is x=15 .
The sample standard deviation is of 9 is s=9.
The sample size is of 10 is n=10.
First, we find the number of degrees of freedom, which is the one less than the sample size, thus df = 9.
Then, looking at the t-table or using a calculator, we find the critical value for a 95% confidence interval, with 9 df, thus t = 2.2622
The margin of error is of:
M=ts/n
Then:
M=2.2622(9/√10)
M=6
The confidence interval is:
x±M
x-M=15-6=9
x+M=15+6=21

x²(x + 7) - 8(x + 7) =
let's put the total multiplier (x + 7) out of brackets
(x + 7)(x² - 8)
consider the following binomial experiment: a survey shows 53% of households in centercity own a dvd player. in a random sample of 22 households in this city, what is the probability that exactly 17 households own a dvd player? a) 0.0121 b) 0.0124 c) 0.0120 d) 0.0123 e) 0.0126 f) none of the above.
The probability that exactly 17 households own a DVD player is b) 0.0124
How to calculate the probability?P = probability of own DVD player = 53% = 0.53
n = sample of households = 22
x = number of households own a DVD player = 17
Since it is binomial experiment, we use binomial probability formula to calculate the probability.
P(X) = [tex]^{n}C_{x}\times P^{x}\times (1-P)^{n-x}[/tex]
With combination formula as below,
[tex]^nC_x[/tex] = [tex]\frac{n!}{x!(n-x)!}[/tex]
P(X) = [tex]^{22}C_{17}\times 0.53^{17}\times (1-0.53)^{22-17}[/tex]
= [tex]\frac{22!}{17!(22-17)!}\times 0.53^{17}\times 0.47^{5}[/tex]
= 26334 × 0.0000205 × 0.0229345
= 0.0123811
= 0.0124
Thus, the probability is 0.0124 for 17 households own DVD player.
