Answer:
3000 notebooks
Step-by-step explanation:
75000 sheets
each sheet has 8 pages
each notebook has 200 pages so,
75000x8=600000
600000/200=3000
Answer:
total number of sheet 75000
each sheet contain 8 page
page required to make not work is 200 pages
so 200 /8 = 25 to make a notebook 25 sheet is required
now, 75000/25 =3000
so, the number of notebook made from total number of sheet available is 3000

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2+1 inches. She plans to make a similar pillow, including the ribbon, whose side length is 4x−7 inches. What expression can be used for the length of ribbon that she needs for both pillows, and what is the length if x = 3.5?
The expression that represents the length of the ribbon and the pillow is [tex]P =4(2(3.5)^2 + 1) + 4(4(3.5) - 7)[/tex]
The side lengths are given as:
Pillow = 2x^2 + 1Ribbon = 4x - 7The shapes are said to be in form of squares.
PerimeterThe perimeter of a square of side length x is calculated using:
[tex]P =4x[/tex]
The expressionThe perimeter of the ribbon and the pillow is:
[tex]P =4(2x^2 + 1) + 4(4x - 7)[/tex]
The value of x is 3.5.
So, the expression becomes
[tex]P =4(2(3.5)^2 + 1) + 4(4(3.5) - 7)[/tex]
[tex]P =130[/tex]
Hence, the expression that represents the length of the ribbon and the pillow is [tex]P =4(2(3.5)^2 + 1) + 4(4(3.5) - 7)[/tex]

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 22.5%, and the final exam is worth 34%. Compute the weighted average for the following scores: 81 on the lab, 75 on the first major test, 97 on the second major test, and 84 on the final exam.
Answer:
The weighted average for the given scores is 84.27
Step-by-step explanation:
The weighted average can be calculated from the formula
Weighted average = [tex]\frac{\Sigma wx}{\Sigma w}[/tex]
Where w is the weight
and x is the score
The scores are 81, 75, 97, and 84 while their respective weights are 21% (0.21), 22.5%(0.225), 22.5%(0.225), and 34%(0.34).
From the formula
Weighted average = [tex]\frac{\Sigma wx}{\Sigma w}[/tex]
Since we have four sets of values, we can write that
Weighted average = [tex]\frac{\Sigma wx}{\Sigma w}[/tex] = [tex]\frac{w_{1}x_{1} + w_{2}x_{2} + w_{3}x_{3} + w_{4}x_{4}}{w_{1} + w_{2} + w_{3} + w_{4}}[/tex]
Let 81, 75, 97, and 84 be [tex]w_{1}, w_{2}, w_{3},[/tex] and [tex]w_{4}[/tex] respectively; then
0.21, 0.225, 0.225, and 0.34 will be [tex]x_{1}, x_{2}, x_{3},[/tex] and [tex]x_{4}[/tex] respectively.
∴ Weighted average = [tex]\frac{(81)(0.21)+(75)(0.225)+ (97)(0.225) +(84)(0.34)}{0.21+0.225+0.225+0.34}[/tex]
Weighted average = [tex]\frac{17.01+16.875+21.825+28.56}{1}[/tex]
Weighted average = 84.27
Hence, the weighted average is 84.27

It is well documented that active maternal smoking during pregnancy is associated with lower-birth-weight babies. Researchers wanted to determine if there is a relationship between paternal smoking habits and birth weight. The researchers administered a questionnaire to each parent of newborn infants. One question asked whether the individual smoked regularly. Because the survey was administered within 15 days of birth, it was assumed that any regular smokers were also regular smokers during pregnancy. Birth weights for the babies (in grams) of nonsmoking mothers were obtained and divided into two groups, nonsmoking fathers and smoking fathers. The accompanying data are representative of the data collected by the researchers. The researchers concluded that the birth weight of babies whose father smoked was less than the birth weight of babies whose father did not smoke. Complete parts (a) through (g) below.
a.) It is____________ (a designed experiment OR an observational study) because the researchers ____________(intentionally changed OR the value of an explanatory variable.
b.) What is the explanatory variable? What is the response variable?
Explanatory variable is ___________(whether or not the mothers smoked OR smokers OR whether or not the father smoked OR non smokers OR birth weight.)
Response variable is__________ (whether or not the mothers smoked OR smokers OR whether or not the father smoked OR non smokers OR birth weight.)
c.) Can you think of any lurking variables that may affect the results of the study? Select all that apply.
-Shopping habits
-Eating habits
-Father's weight
-Exercise habits
-Whether the mother received prenatal care
d.) In the article, the researchers stated that "birthweights were adjusted for possibleconfounders..." What does this mean?
-The researchers attempted to adjust their results for any variables that may also be related to smokers.
-The researchers attempted to adjust their results for any variables that may also be related to nonsmokers.
-The researchers attempted to adjust their results for any variables that may also be related to birth weight.
-The researchers attempted to adjust their results for any variables that may also be related to father's weight.
e.) Determine the summary statistics.
Nonsmokers mean=___ grams
Nonsmokers median=____ grams
Nonsmokers standard deviation= ____ grams
Nonsmokers first quartile=_____ grams
Nonsmokers third quartile=____ grams
Smokers mean=___ grams
Smokers median=____ grams
Smokers standard deviation= ____ grams
Smokers first quartile=_____ grams
Smokers third quartile=____ grams
f.) Interpret the first quartile for both the nonsmoker and smoker group.
OPTION A. For the two groups, 50% of infants in each group have birth weights less than or equal to the first quartile for thatgroup, and 50% of infants in each group have birth weights greater than the first quartile for that group.
OPTION B.For the two groups, 25% of infants in each group have birth weights less than or equal to the first quartile for thatgroup, and 75% of infants in each group have birth weights greater than the first quartile for that group.
OPTION C.For the two groups, 75% of infants in each group have birth weights less than or equal to the first quartile for thatgroup, and 25% of infants in each group have birth weights greater than the first quartile for that group.
g.) Draw a side-by-side boxplot of the data. Does the side-by-side boxplot confirm the conclusions of the study?
Does the side-by-side boxplot confirm the conclusions of thestudy?
OPTION A.The boxplot does not confirm the study as the medians are very close to each other; the third quartiles are noticeablydifferent, but not the medians.
OPTION B.The boxplot does not confirm the study as the median for smokers is significantly more than the median for nonsmokers; the median is located close to the third quartile of nonsmokers.
OPTION C. The boxplot confirms the study as the median for smokers is significantly more than the median for nonsmokers; the median is located close to the third quartile of nonsmokers.
OPTION D. The boxplot confirms the study as the median for smokers is significantly less than the median for nonsmokers; the median is located close to the first quartile
Explanation:
a. It is an observatory study because the researchers did not alter the variables such as assigning some parents to smoke.
b. The explanatory variable here since the research is focused on fathers is: whether or not the father smoked. While the response variable is: birth weight.
c. Some of the lurking variables that can affect the results of the study includes;
-Eating habits
-Father's weight
d. It means the researchers attempted to adjust their results for any variables that may not be related to birth weight. In other words, they removed any bias results.
e.) Determine the summary statistics.
Nonsmokers mean= 3665.5 grams
Nonsmokers median= 3693.5 grams
Nonsmokers standard deviation= 356
Nonsmokers first quartile= 3432.8 grams
Nonsmokers third quartile= 3980.5 grams
Smokers mean= 3460.4 grams
Smokers median= 3475 grams
Smokers standard deviation= 452.6 grams
Smokers first quartile= 3113.3 grams
Smokers second quartile= 3828.3 grams
f.) The first quartile for both the nonsmoker and smoker group can be interpreted as 25% (the first quartile) of infants have a birth weight below 3432.8 grams. While for smokers 25% of their infants had birth weight below 3113.3 grams. (or OPTIONS B).
g.) OPTION D. The boxplot confirms the study as the median for smokers is significantly less than the median for nonsmokers; the median is located close to the first quartile

give me brainliest.The local cable company charges $90 per month for basic and $12 per month for each additional premium cable channel.The function c(x)=90x+12x represents the monthly charge (in dollars),where x represents the number of additional premium channels.How many additional premium channels would you have ordered if your bill wad $114 per month?
Answer:
2 additional premium channels
Step-by-step explanation:
Using the given function, we substitute c(x) = 114 and solve for x:
114 =90 + 12x
Subtract 90 from both sides:
24=12x
Divide both sides by 12:
2=x
So you have ordered 2 additional premium channels.
2 additional premium channels would you have ordered if your bill was $114 per month.
The given function is c(x)=90+12x.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
We need to find the number of additional premium channels would you have ordered if your bill was $114 per month.
So, 114=90+12x
⇒ 12x=114-90
⇒ 12x=24
⇒ x=2
Therefore, 2 additional premium channels would you have ordered if your bill was $114 per month.
