Final answer:
The marketing firm's survey, where a sample of people is asked if they use a product, is an example of survey research aimed at observing and measuring characteristics without attempting modification. This cross-sectional study helps understand consumer behavior. (Option C)
Explanation:
The survey described by the marketing firm where one hundred people are contacted and fifteen confirm that they use the product is an example of survey research, which is a quantitative research method. In this survey, the firm is observing and measuring specific characteristics of the subjects, but not attempting to modify the subjects. This type of survey can help the firm in understanding consumers' preferences, tastes, attitudes, and behaviors regarding the use of the product. They are not applying any treatment to the subjects or observing them over time as would be done in a longitudinal study. Instead, they're conducting a cross-sectional survey at a single point in time. (Option C)
A father is giving his child a 30-inch long softball bat for her birthday.He has a rectangular box that has the dimensions of 5 inches by 6 inches by 25 inches. Will the bat fit in the box ? Explain
Answer:
No, the bat will not fit. Using the Pythagorean theorem, the length of a diagonal of a face of the box is about 24 inches, and the length of the diagonal of the cube is about 29.4 inches. This is less than the length of the bat.

James bought $175 in accessories for his video game console. He spent $15 on a new power cord and the rest of his money on 5 new video games. Each video game cost the same amount. Write two equations you could use to find the cost of each video game.
The solution is, two equations are: (175-15)/5 and, 5x+15=175
the cost of each video game is 32.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here, we have,
two equations we can make to represent the question are...
(175-15)/5
and
5x+15=175
The first equation, (175-15)/5, makes you subtract 15 from 175 to get 160. You'll then divide 160 by 5 to get 32.
The second equation, 5x+15=175, makes you subtract 15 from 15 and 175, so you'll equation will look like this...
5x=160
You'll then divide 5x and 160 by 5 to get x=32.
So for both equations, we'll get an answer of 32.

lyzette's folder has a permeter of 38 inches.if the length of the paper is 11 inches what is the width of the folder
Final answer:
To find the width of Jyzette's folder with a perimeter of 38 inches and a length of 11 inches, we use the perimeter formula for a rectangle, solve for width, and find that the width of the folder is 8 inches.
Explanation:
Finding the Width of a Folder
To determine the width of Jyzette's folder, we use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is perimeter, l is length, and w is width. Given that the perimeter is 38 inches and the length is 11 inches, we can set up the equation:
38 = 2(11) + 2w
Simplifying the equation: 38 = 22 + 2w. We then subtract 22 from both sides, resulting in 16 = 2w, and finally, dividing both sides by 2 gives us w = 8. Therefore, the width of the folder is 8 inches.

which expression defines the given series for seven terms? -13 + (-16) + (-19) +...
Answer:
[tex]a_n =-3n-10[/tex]
Step-by-step explanation:
-13 + (-16) + (-19) +...
Difference between two terms = -3
-16 -(-13)= -3
-19 -(-16)= -3
Common difference is a constant so it is arithmatic
[tex]a_n = a_1+(n-1)d[/tex]
where 'd' is the difference = -3
a1 is the first term that is -13
[tex]a_n = -13+(n-1)(-3)[/tex]
[tex]a_n = -13-3n+3[/tex]
Combine like terms
[tex]a_n =-3n-10[/tex]

The radius of a cone can be found using the formula r=3Vπh , where V stands for the volume of the cone and h stands for the height. If r=3 , h=8 , and π is 3.14, find the volume (V). Round the answer to the nearest hundredths place.
Using the formula for the radius of a cone and the given values of r = 3, h = 8, and [tex]\pi[/tex] = 3.14, the volume of the cone is calculated to be approximately 25.12 [tex]cm^3[/tex].
To find the volume V of a cone, we need to solve for V in the given formula [tex]\( r = \frac{3V}{\pi h} \). With \( r = 3 \),[/tex] h = 8, and [tex]\pi = 3.14[/tex], let's proceed as follows:
Rearrange the Formula
1. Given that [tex]\( r = \frac{3V}{\pi h} \)[/tex], isolate V to get:
[tex]\[ V = \frac{r \cdot \pi \cdot h}{3} \][/tex]
2. Using r=3, h=8, and [tex]\( \pi = 3.14 \)[/tex]:
[tex]\[ V = \frac{3 \cdot 3.14 \cdot 8}{3} \][/tex]
3. Simplify and solve:
[tex]\[ V = 3.14 \cdot 8 \approx 25.12 \][/tex]
Rounding to the nearest hundredths place, the value for the volume V is approximately 25.12 cubic units.

Aisha wants to make two quilts, each with the same area. The first quilt will be square with sides s feet long. The second quilt will be a rectangle with a width that is half the length of a side of the square quilt and a length that is 6 feet longer than a side length of the square quilt. Which quadratic equation can be used to find s, the side length of the square quilt?
s^2 =(1/2s) (s + 6)
s^2 = (s)(s + 6)
s^2 =(1/2s) (6s)
s^2 = (s)(6s)
Answer:
Option 1 - [tex]s^2=(\frac{1}{2}s)(s+6)[/tex]
Step-by-step explanation:
Given : Aisha wants to make two quilts, each with the same area. The first quilt will be square with sides s feet long. The second quilt will be a rectangle with a width that is half the length of a side of the square quilt and a length that is 6 feet longer than a side length of the square quilt.
To find : Which quadratic equation can be used to find s, the side length of the square quilt?
Solution :
The first quilt will be square,
Let the side of square be s
The area of the square is [tex]A=s\times s[/tex]
The second quilt will be a rectangle,
A width that is half the length of a side of the square quilt and a length that is 6 feet longer than a side length of the square quilt.
Width of the rectangle = [tex]\frac{1}{2}s[/tex]
Length of the rectangle = s+6
Area of the rectangle is [tex]A=(\frac{1}{2}s) \times (s+6)[/tex]
According to question,
Area of square and rectangle are equal,
So, [tex]s\times s=(\frac{1}{2}s) \times (s+6)[/tex]
[tex]s^2=(\frac{1}{2}s)(s+6)[/tex]
Therefore, Option 1 is correct.
The required equation is [tex]s^2=(\frac{1}{2}s)(s+6)[/tex]

Han has 410,000 in a retirement accounts that earns 15,785 each year find the simple interest rate for this investment
The simple interest rate on this investment is.0385 or 3.85%:
What is Simple Interest?Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
Given:
Han has 410,000 in a retirement accounts that earns 15,785 each year.
Using Simple Interest
Interest = principle x rate x time / 100
Rate = Interest / ( principle x time )
Rate = 15785/(410,000x1)
Rate = 0.0385
Rate= 3.85 %

True or False? The shortest distance from the center of the circumscribed circle to the sides of the inscribed triangle is the circle's radius
Answer:
false
Step-by-step explanation:
The statement that the shortest distance from the center of the circumscribed circle to the side of the inscribed triangle is the circle's radius is false.
How to find the radius of the circumscribed circle around a triangle?The intersection of the perpendicular bisectors of any two sides(or all three sides if you want) is the center of the circumscribed circle for that triangle.
The length of that intersection point from any of the vertices of the triangle is the radius of the circumscribed circle of that triangle.
When a triangle is placed in a circle such that the side of the circle touch the circumference of the circle, then the circle is a circumscribed circle.
The line drawn from the center of the circle to the side of the triangle is the shortest possible line.
However, it is certain that this line is the radius.
This is so because the side of the triangle lie on the circumference of the circle
Hence, the statement that the shortest distance from the center of the circle is false.
