In a survey of 1,500 people who owned a certain type of car, 750 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
If in a survey of 1,500 people who owned a certain type of car, 750 said they would buy that type of car again, the percent of people surveyed who were satisfied with the car is 50%.
To find the percent of people surveyed who were satisfied with the car, we can use the following formula:
percent satisfied = (number of satisfied people / total number of people surveyed) x 100
In this case, the number of satisfied people is 750 and the total number of people surveyed is 1,500. So we have:
percent satisfied = (750 / 1,500) x 100 = 0.5 x 100 = 50%
So, 50% of the people surveyed were satisfied with the car.

How do you draw a logarithmic graph?
Choose the range of values for the x-axis and the y-axis , Plot the points on the graph, using the logarithmic formula , Connect the points with a smooth curve and Label the axes and add any other details you want to include.
1. Choose the range of values for the x-axis and the y-axis. Select the minimum and maximum values for both the x-axis and the y-axis.
2. Plot the points on the graph, using the logarithmic formula. Use the formula log(x) = y to calculate the points that should be plotted on the graph. For example, if the x-axis range is from 1 to 10, and the y-axis range is from 0 to 10, then the first point would be (1,0).
3. Connect the points with a smooth curve. Once all the points have been plotted, use a ruler or a graphing calculator to connect them with a smooth curve.
4. Label the axes and add any other details you want to include. Use a ruler or a graphing calculator to label the axes and add any other details you want to include, such as a title, a legend, or a grid.

Answer:
y is > 7
Step-by-step explanation:
Any y value greater than 7 would make the product greater than 5. This can be looked at as y > 7. So y/7 can be rthough of as y divided by 7. 5 x y/7 can be though of as y * 5 divided by 7. Or 5y/7. To make this value 5, y must be 7. Since 7/7 is 1, and 1*5 is 5. If the number is greater than this it would have to be >7/7, since this would make it >1*5. So y must be >7. Hope this helps!

simplify cos^2 A/1+sin A
Answer:
[tex]\displaystyle \frac{\cos^2(A)}{1+\sin(A)}=1-\sin(A)[/tex]
Step-by-step explanation:
We want to simplify:
[tex]\displaystyle \frac{\cos^2(A)}{1+\sin(A)}[/tex]
Recall the Pythagorean Identity:
[tex]\sin^2(A)+\cos^2(A)=1[/tex]
So:
[tex]\cos^2(A)=1-\sin^2(A)[/tex]
Substitute:
[tex]\displaystyle =\frac{1-\sin^2(A)}{1+\sin(A)}[/tex]
Factor. We can use the difference of two squares pattern:
[tex]\displaystyle =\frac{\left(1-\sin(A))(1+\sin(A))}{1+\sin(A)}[/tex]
Cancel. Hence:
[tex]\displaystyle \frac{\cos^2(A)}{1+\sin(A)}=1-\sin(A)[/tex]
What are the coordinates of the point on the directed line segment from
3. 2) to (77) that nartitions the segment into a ratio of 3 to 2?
Answer:
(4.6, 4)
Step-by-step explanation:
Given the coordinates (3,2) and (7, 7) partitioned between 3:2
M(X,Y) = [(ax1+bx2/a+b, ay1+by2/a+b)]
X = 3(3)+2(7)/3+2
X = 9+14/5
X = 23/5
X = 4.6
Similarly;
Y = 3(2) + 2(7)/3+2
Y = 6+14/5
Y = 20/5
Y = 4
Hence the required coordinate is (4.6, 4)

How do you write numbers more than 100?
The numerical figures are used to write numbers more than 100.
What is numbers?
An arithmetic value known as a number is used to represent a quantity and perform calculations. Numbers are represented by written symbols, such as "3," which are referred to as numerals. A number system is a method of writing that uses logically ordered digits or symbols to represent numbers.
To represent numbers greater than 100, use numeral figures; however, whole numbers, such as 300 or 1,000, should be written out.
When representing non-whole numbers like 1,239 or 603, use numerals.
Except for whole numbers combined with hundred, thousand, hundred thousand, million, billion, and beyond, the Chicago Manual of Style advises spelling out numbers from zero to one hundred and using figures after that (e.g., two hundred; twenty-eight thousand; three hundred thousand; one million).
Hence, the numerical figures are used to write numbers more than 100.

4. — 20.1, 13.4, 9.8, 21.3, 20.8, 19.1, 68.1, 22.6
Mean
The mean of the data is the sum of the data values, divided by the number of data values.
MedianThe median data value is the middle of the sorted list, or the average of the two middle values. Here, there are an even number of data values in each list, so the median is the average of the middle two.
ModeThe mode of the data set is the value that is repeated most often. A data set may have multiple modes. Here, where one of the datasets has no repeated values, we describe it as having "no mode."
Data set 2The first attachment shows the descriptive statistics are ...
mean: 53.75median: 56.5mode: 65The data is skewed to the left, with the value 22 being an outlier. This value reduces the mean. The mode is the maximum value in the data set, so it does not fairly represent the data, either.
The median best represents the data.
Data set 4The second attachment shows the descriptive statistics are ...
mean: 24.4 median: 20.45mode: none (no repeated values)The data is skewed to the right, with the value 68.1 being an outlier. This tends to raise the mean above what it would otherwise be. There is no mode.
The median is best represents the data.

What is the coefficient form of X³ 2 *?
Let x= the co-efficient of x^2. So the co-efficient of given function is x=1.
Define co-efficient.
The term "coefficient" refers to a number or symbol that multiplies another number or symbol (used as a mathematical variable).
Write an example of co-efficient.
An amount multiplied by a variable is known as a coefficient. As an illustration, 6z stands for 6 times z. Since z is a variable, 6 is a coefficient. For variables without a value, the coefficient is 1.
Let x= the co-efficient of x^2 So the co-efficient of given function is x=1.
The term multiplied with x^3 is the co-efficient of this expression. As there is not term with x^2 so it is 1.

The sum of three consecutive integers is 27. Find the value of the greatest of the three.
Answer: The greatest of the three is 10.
Step-by-step explanation:
27/3=9 so the numbers will be around nine.
8+9+10=27
Answer:
Let x represent the value of the smallest of the three consecutive integers.
Then, the value of the middle integer is x+1, and the value of the greatest integer is x+2.
Since the sum of the three integers is 27, we have:
x + (x+1) + (x+2) = 27
Combining like terms, we have:
3x + 3 = 27
Subtracting 3 from both sides, we have:
3x = 24
Dividing both sides by 3, we have:
x = 8
Therefore, the value of the smallest integer is 8, the value of the middle integer is 8+1 = 9, and the value of the greatest integer is 8+2 = 10.
Thus, the value of the greatest integer is 10.
