A package of 10 cans of soup costs $14. An individual can costs $2. You need at least 25 cans. Find the price of each combination of items.
Answers
5 x 2= $10
the answer is $38
Step-by-step explanation:
Since each package of 10cans costs $14
25cans would be 2 packages + 5 (since a package has 10)
So
14$ x 2 + 2$ x 5
=38$.
On their birthdays, employees at a large company are permitted to take a 60-minute lunch break instead of the usual 30 minutes. Data were obtained from 10 randomly selected company employees on the amount of time that each actually took for lunch on his or her birthday. The company wishes to investigate whether these data provide convincing evidence that the mean time is greater than 60 minutes. Of the following, which information would NOT be expected to be a part of the process of correctly conducting a hypothesis test to investigate the question, at the 0.05 level of significance?
A. Being willing to assume that the distribution of actual birthday lunch times for all employees at the company is approximately normal
B. Knowing that there are no outliers in the data as indicated by the normal probability plot and boxplot
C. Using a t-statistic to carry out the test
D. Using 9 for the number of degrees of freedom
E. Given that the p-value is greater than 0.05, rejecting the null hypothesis and concluding that the mean time was not greater than 60 minutes.
Answers
Answer:
The answer is "Option E"
Step-by-step explanation:
The null hypothesis was rejected so because the p-value was greater than 0.05, indicating that perhaps the meantime was not greater than 60 minutes.

Find the value of x.
Answers
Answer:
x = 4.
Step-by-step explanation:
The lengths of the line segments on both sides of the triangle are in the same ratio, so:
3 / 2 = x+2/x
2(x+2) = 3x
2x + 4 = 3x
2x - 3x = -4
-x = -4
x = 4.

Is it appropriate to identify values on this graph that are between or beyond the plotted points? Explain.
Answers
Note that It is not a good idea to guess what a value on a graph might be if it is beyond the points that are already plotted. The reason for this is that the guess might not be accurate. Generally, it is better to stay within the defined data limits.
What is a graph?In mathematics, a graph is defined as a graphical representation or diagram that organizes facts or values. The graph's points frequently reflect the relationship between two or more objects.
Because they display information quickly and readily, graphs and charts are powerful visual aids. It's no surprise that graphs are widely utilized in print and electronic media. Data can often be easier understood when displayed as a graph rather than a table since the graph might illustrate a pattern or comparison.

. Which of the following is the graph of the equation y = 2x + 3?
Answers
Answer:
The graph of the equation y = 2x + 3 is a straight line that passes through the point (0,3) and has a slope of 2.
It can be represented as a set of points in a coordinate plane. The slope of the line is 2, so for every unit increase in x (horizontal coordinate), y (vertical coordinate) increases by 2 units. The y-intercept of the line is 3, so when x is 0, y equals 3.
A line passing through (0,3) with a slope 2 can be represented as (x, 2x + 3)
It is important to note that an equation in the form of y = mx + c, with m being the slope and c being the y-intercept, always represents a straight line in a coordinate plane.
Step-by-step explanation:
Which can be the first step in finding the equation of the line that passes through the points (5.-4) and (-1,8) in

Answers
In slope-intercept form, the equation of the line passing through the points (5.-4) and (-1,8) is y = -4x + 8 .
what is equation ?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equality of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to express the connection between two phrases on either side of a letter.
given
the points (5.-4) and (-1,8)

slope intercept form = y = mx + c
To find the equation of the line that passes through the points (5, -4) and (-1, 8),
The slope and the intercept by the slope intercept form = y = mx + c .
The slope is -4 and the intercept is 8.
In slope-intercept form, the equation of the line passing through the points (5.-4) and (-1,8) is y = -4x + 8 .

What is polynomia?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics. Polynomials come in various varieties. Monomial, binomial, and trinomial, respectively.
Given four linear equations in them we need to state which equation is an example of direct variation.
The direct variation equation has the form y = kx, where k is the constant proportionality. It is a linear equation with two variables. In a coordinate plane, the direct variation graph is a straight line. A constant is the ratio of two quantities that vary directly. Or in other words, the direct variation equation always passes through the origin point of a cartesian plane or (0, 0).
Therefore, in the given options y = -12/x is the only equation that is an example of direct variation.

The goal for the size of the Santa on a Christmas Santa cup is 3. 5 cm with an acceptable tolerance of ± 0. 9 cm. The grand mean of the size of the Santa from the samples that were taken is 3. 4 cm and the standard deviation is 0. 28 cm. What is CP? (rounded to three decimals)
Answers
The processing capability for the size of the Santa rounded to three decimal places is 1.07.
CP (Process Capability) is a statistical measure that compares the performance of a process to the specifications of that process. It can be calculated using the formula:
CP = (USL - LSL) / (6 * standard deviation)
Where:
USL = Upper Specification Limit (3.5 + 0.9) = 4.4 cm
LSL = Lower Specification Limit (3.5 - 0.9) = 2.6 cm
Standard deviation = 0.28 cm
Substituting these values into the formula:
CP = (4.4 - 2.6) / (6 * 0.28) = 1.8 / 1.68 = 1.07
So, CP rounded to three decimal places is 1.07

How do I solve this equation?
Answers
Answer:
x = 1
Step-by-step explanation:
Immediately, we will simplify like terms on the left side of the equation. This will give us:
[tex]\sqrt{2x-x-1}[/tex] = 0
Simplifying gives us:
[tex]\sqrt{x-1}[/tex] = 0
Now, an important thing to note, is that for the square root of a number to be 0, the number has to be 0. Therefore, x - 1 must equal 0. So, x = 1. Checking our work gives us:
[tex]\sqrt{2x - x - 1}[/tex] = 0
[tex]\\\sqrt{2 - 1 - 1}[/tex] = 0
[tex]\sqrt{0}[/tex] = 0
It all checks out.

Yolanda spends 8 2/3 hours per month playing soccer. approximately how many hours does she play soccer in a year?
Answers
Answer:
[tex]8 \frac{2}{3} \times 12 = 104[/tex]
Therefore, she spends 104 hours a year playing soccer.
Answer:
104 hours
Step-by-step explanation:
1 year = 12 months
Since 1 year equals 12 months, we multiply the time she spends in 1 month by 12 to calculate the time she spends in 1 year.
8 2/3 hours × 12
= (8 + 2/3) hours × 12
= (8 × 12 + 2/3 × 12) hours
= (96 + 8) hours
= 104 hours

How would the information collected using transect or quadrat sampling differ from the information collected if you had just divided the habitat into quarters and sampled only one of the quarters
Answers
I feel that dividing based off actual zoning laws and regulations would provide the best source of data. I feel as such because if you simply devise your own areas, that may make your data incorrect depending on what area a person actually associates with. If you're creating your own area, information could get misconstrued leading to inaccurate conclusions.
Sampling
Sampling means selecting the group that you will actually collect data from in your research.
