Answer:
Dependent variable: Amount of oranges ([tex]y[/tex]), measured in pounds.
Independent variable: Money ([tex]x[/tex]), measured in US dollars.
Equation: [tex]y = 1.15\cdot x[/tex]
Step-by-step explanation:
According to the statement, Maria pays money to buy oranges at the grocery and there is a direct proportionality between money ([tex]x[/tex]), measured in US dollars, and the amount of oranges ([tex]y[/tex]), measured in pounds. That is:
[tex]y \propto x[/tex]
[tex]y = k\cdot x[/tex]
Where [tex]k[/tex] is the proportionality constant, measured in US dollars per pound.
The dependent variable is the amount of oranges ([tex]y[/tex]), whereas money ([tex]x[/tex]) represents the independent variable. If we know that [tex]k = 1.15\,\frac{USD}{pd}[/tex], then the equation is:
[tex]y = 1.15\cdot x[/tex]
In a nutshell, the answer is:
Dependent variable: Amount of oranges ([tex]y[/tex]), measured in pounds.
Independent variable: Money ([tex]x[/tex]), measured in US dollars.
Equation: [tex]y = 1.15\cdot x[/tex]
how are reflections mathematical formulas used in the computer industry?
Answer When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
Step-by-step explanation:
Describe the end behavior for the cubic function f (x)=-x^3-4
Answer:
"Cubic functions are functions with a degree of 3 (hence cubic ), which is odd. Linear functions and functions with odd degrees have opposite end behaviors. The format of writing this is:
x → ∞ , f ( x ) → ∞
x → − ∞ , f ( x ) → − ∞
For example, for the picture below, as x goes to ∞
, the y value is also increasing to infinity. However, as x approaches - ∞
, the y value continues to decrease; to test the end behavior of the left, you must view the graph from right to left!!
graph{x^3 [-10, 10, -5, 5]}
Here is an example of a flipped cubic function, graph{-x^3 [-10, 10, -5, 5]}
Just as the parent function (
y = x 3
) has opposite end behaviors, so does this function, with a reflection over the y-axis.
The end behavior of this graph is:
x → ∞ , f ( x ) → − ∞x → − ∞ , f ( x ) → ∞
Even linear functions go in opposite directions, which makes sense considering their degree is an odd number: 1."

oes regular exercise reduce the risk of a heart attack? Provided are two ways to study this question. A researcher finds 20002000 men older than age 4040 who exercise regularly and have not had heart attacks. She matches each with a similar man who does not exercise regularly, and she follows both groups for 55 years. Another researcher finds 40004000 men older than age 4040 who have not had heart attacks and are willing to participate in a study. She assigns 20002000 of the men to a regular program of supervised exercise. The other 20002000 continue their usual habits. The researcher follows both groups for 55 years. Select the correct explanation clearly detailing why the second design will produce more trustworthy data.
Answer:
The first design does not specify the age and the number of the group not exercising.
Step-by-step explanation:
The second design will produce more trustworthy data because there are equal number of men above the age of 40 grouped into two categories those who exercise and those who do not exercise.
The first design does not produce such accurate results because the two sample sizes may be quite different and the second group may have candidates of any age other than 40.
The null hypothesis for this design will be u ≠ 40 against the alternate hypothesis that u= 40.
This will give a two tailed test.
All the result possibilities will be for both men aged above 40 and below 40 excluding out only the 40 aged men.
In the second design the sample sizes are same and the both samples may have men aged older than 40
The null hypothesis for this design will be u => 40 (Mean is greater and equal to 40) against the claim u < 40 .
This will give a one tailed test.
So this design will give better results.
All the result possibilities will be for men aged above 40.

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
On Friday night, Suzie babysat her cousin for 3 1/2 hours and earned $8.50 per hour.
On Saturday, she babysat for her neighbors for 4 1/2hours.
let Suzie earn $y per hour on Saturday.
3 1/2 x 8.5 + 4 1/2 x y = 72.5
7/2 x 8.5 + 9/2 y = 72.5
29.75 + 4.5y = 72.5
4.5 y = 42.75
y = 9.5
Hence, Suzie earn $9.5 per hour.

Step-by-step explanation:
mean means averageie 2+28+2+20+22/5 = 14.8 yearsHe is paid a commission of 9 percent of his first $6,000 in sales during the month and 14 percent on all sales over $6,000. What is his commission in a month in which he has sales worth $16,120?
Answer:
$1,956.80
Step-by-step explanation:
For amounts over $6000, the commission can be computed as ...
0.14s -300 . . . . . . for sales (s) ≥ 6000
So, for $16,120 in sales, the commission is ...
0.14×$16,120 -300 = $2,256.80 -300 = $1,956.80
__
The commission schedule suggests that for larger amounts, you divide the problem into two parts: calculate the commission on $6000, and separately calculate the commission on the amount over $6000.
0.14(s -6000) + 0.09(6000)
= 0.14s - 0.14·6000 +0.09·6000
= 0.14s -300 . . . . the formula used above for s ≥ 6000

For the point-slope equation, we need the y-intercept and the slope of the line
From the graph, we can see that the y-intercept of the given line is '3'
To find the slope, we will take the line of the graph from (-2,0) to (0,3)
in between these points, we can see that the rise = 3 and the run = 2
Slope = rise / run
Slope = 3/2
Now making the point-slope equation
the general form of these equations is :
y = mx + b (where m is the slope and b is the y-intercept)
Therefore the equation is
y = (3x/2) + 3

Step-by-step explanation:
So this is actually a proportion:
The large triangle to the smaller one:
The angles of the triangles are the same so they are proportional
We know the larger one is 20/8 times the smaller one's sides because
YZ = something times QR so:
20 = 8 times 20/8
In order to find PR, we have to divide ZX by the proportion rate thing so:
32 / (20/8)
= 32 * 8/20
= 64/5
= 12.8
119 divided by 17? with remainder?
Answer:
A number, when divided by 119, leaves a remainder of 19. If it is divided by 17, it will leave a remainder of 2
Step-by-step explanation:
There is no remainder, and the quotient is 7.
When dividing 119 by 17, we find:
119 ÷ 17 = 7
The quotient is 7. However, there is no remainder because 119 is evenly divisible by 17.
Therefore, 119 divided by 17 is 7 with no remainder.
