Answer:
stratified sample
Step-by-step explanation:
The kind of sample that is being described is known as a stratified sample. This would be the type of sample because the researchers are dividing the entire student population that exists into various different categories or groups. The groups that have been created are home-schooled students, private school students, and public school students. All of the students are still part of the student population and therefore represent their groups.

Step-by-step explanation:
On a large college campus, the students are able to get free copies of the school newspaper,the local newspaper, and a national paper. Ninety percent of the students read at least one of thepapers, 40% read only the school newspaper, 20% read only the local paper, 5% read only thenational paper, and 2% read all three papers. Fifty percent read the school newspaper, and 5%read the school and national newspapers. A randomly selected student is asked whether he orshe reads the school, local, or national paper. Express each of the following events in setnotation and find the percentage of students represented by each.a The student does not read any paper.b. The student reads the local paper.c. The student reads exactly two papers.d. The student reads at least two papers.
Answer:
a) The percentage that the student does not read any paper is 10%
b) The percentage that the student reads the local paper is 40%
c) the percentage that the student reads exactly two papers is 23%
d) the percentage that the student reads at least two papers is 25%
Step-by-step explanation:
Given the data in the question;
as illustrated in the Venn diagram below,
a)The student does not read any paper;
The percentage that the student does not read any paper will be;
100% - 90% = 10%
Therefore, The percentage that the student does not read any paper is 10%
b) The percentage that the student reads the local paper;
from the Venn diagram below;
⇒ ( 20 + 15 + 3 + 2 )%
= 40%
Therefore, The percentage that the student reads the local paper is 40%
c) The percentage that the student reads exactly two papers
⇒ ( 15 + 5 + 3 )%
= 23%
Therefore, the percentage that the student reads exactly two papers is 23%
d) The percentage that the student reads at least two papers;
⇒( 15 + 5 + 3 + 2 )%
= 25%
Therefore, the percentage that the student reads at least two papers is 25%

????????????????????????????
The number of books Susan borrowed is 30 books.
Given that
Richard borrowed 17 books.Richard borrowed half as many as Linda has, so For Linda, it should be 17 × 2 = 38 books.Linda borrowed 8 books more as compared with Susan.So, Susan should borrow books of
= 38 - 8

How many brownies had nuts?
Answer:
Incomplete problem - reword
Step-by-step explanation:
3 brownies had nuts.
What is a Fraction?In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that were taken.
As per the given data:
Brownies in each box = 15
Boxes handed out = 1 [tex]\frac45[/tex]
Brownies with nuts = (1/9) of the brownies
Boxes handed out = 1 [tex]\frac45[/tex] = (9/5) boxes
Total brownies handed out = (9/5) × 15 = 27 brownies
Total brownies with nuts = (1/9) of 27 = (27/9) = 3 brownies with nuts.
Hence, 3 brownies had nuts.

Please help if you can thank you
Answer:
c. -18.5x ≤ 407
Step-by-step explanation:
-18.5 x -22 = 407
-18.5 x 0 = 0
-18.5 x 6 = -111
-18.5 x 17 = -314.5
-18.5 x 60 = -1110
(All products are either less than or equal to 407)
11 more than x is less than. 3 (please)
Answer:
(11+x)-3
Step-by-step explanation:
11 more than x is another way of saying 11+x
And "less than 3" means subtracting 3 from the terms
So if you put that together it would be
(11+x) -3
x^2 – 2x – 54 = 0
I need it in completing the square form
Completing the Square:
x^2 - 2x = 54
x^2 - 2x + 1 = 54 + 1
(x-1)^2 = 55
x - 1 = ±[tex]\sqrt{55\\}[/tex]
x = 1 ± [tex]\sqrt{55}[/tex]
Find the slope of the line that contains the following pair of points: (1, 2), (5,2).
O A. - 1
O B. o
O C. 4
OD. Undefined
Answer:
The answer is 0
Step-by-step explanation:
input into slope formula
The slope of the line is 0.
The correct option is (B).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points from the graph (1, 2) and (5, 2).
So, the slope of line
= ( 2- 2) / (5 -1)
= 0 / 4
= 0
Hence, the slope of line is 0.

The legs of the drafting table form vertical angles. Find the measures of ∠1, ∠2 and ∠3.
Answer:
m∡1 = 95°
m∡2 = 85°
m∡3 = 95°
Step-by-step explanation:
m∡1 + 85 = 180; m∡1 = 95°
m∡2 = 85° because it is vertical and congruent to the angle measured 85°
m∡3 = m∡1 = 95° because they are vertical and congruent
Answer:
1 = 95, 2 = 85, 3 = 95
Step-by-step explanation:
2 is an opposite angle of 85 degrees so 2 is 85 degrees
a line is always 180 degrees:
1 = 180 - 85 = 95 degrees
1 is an opposite angle of 3 so 3 is also 95 degrees

81^84375
Step-by-step explanation:
The mean is usually the preferred measure of central tendency, but there are specific situations in which it is impossible to compute a mean or in which the mean is not particularly representative of the distribution. Which of the following statements about the mean are true?
a. It is commonly referred to as the arithmetic average.
b. It is algebraically defined (that is, there is an equation you can use to calculate its value).
c. It is easily influenced by extreme scores.
d. It can be used for data that are measured on a nominal scale.
Answer: a. It is commonly referred to as the arithmetic average.
b. It is algebraically defined (that is, there is an equation you can use to calculate its value).
c. It is easily influenced by extreme scores.
Step-by-step explanation:
The mean is also referred to as the "average" and it is gotten by adding every number and the dividing the value gotten by the number of the numbers used for the calculation.
It should be noted that the mean is algebraically defined and can be easily influenced by extreme scores.
