Answer:
ik this is late so sry but um hope this helps someone else in the future?
Step-by-step explanation:
We’re going to see how the masses of objects affect the gravitational force between them. Since gravitational force between two objects depends on the mass and distance between them, as you can see in the chart, as the mass of the objects multiplies, so does the gravitational force between them. To find the actual gravitational force between the two objects, you take the mass of both objects and multiply them. Let’s try and find the gravitational force between them. First, we have to find the mass of the object, so we’ll take the mass of objects 1 and 2 in the first equation. So let’s start with object 1, 1x10 to the 20th power which equals 10 to the 20th power, now object 2, 1x10 to the 20th power which equals 10 to the 20th power. Now we multiply the masses to get the gravitational force of 10 to the power of 40.

3. The marginal product of the sixth worker is 405 units.
4. The average total cost of producing 425 units of output is $30.
5. The average variable cost of producing 400 units of output is $20.
6. The average fixed cost of producing 430 units of output is $0.07.
What is the answers to the question?The marginal product of the second worker:
= (Output of 2 workers - Output of 1 worker)
= (250 - 100)
= 150 units
The total output of five workers is:
= Output of 4 workers + Marginal product of the fifth worker
= 50 + 25
= 75 units
The marginal product of the sixth worker is:
= (Output of 6 workers - Output of 5 workers)
= (430 - 25)
= 405 units.
The average total cost to produce 425 units is:
= (Total variable cost + Total fixed cost) / Total output
The total variable cost is $30 * 425 = $12,750
The total fixed cost is $5 * 6 = $30
Total cost = $12,750 + $30 = $12,780
The Average total cost is:
$12,780 / 425
= $30
The average variable cost to produce 400 units is:
= Total variable cost / total output
Total variable cost is $20 * 400 = $8,000
Average variable cost = $8,000 / 400 = $20
The average fixed cost to produce 430 units is:
= Total fixed cost / Total output
Total fixed cost is $5 * 6 = $30
The average fixed cost is:
= $30 / 430

The exact value of sin θ is 9/13.
Option A is the correct answer.
We have,
In trigonometry,
The sine function (sin) represents the ratio of the length of the side opposite an angle in a right triangle to the length of the hypotenuse.
The cosecant function (csc) is the reciprocal of the sine function, meaning it is equal to 1 divided by the sine of an angle.
In this case,
We are given that csc θ (the cosecant of θ) is equal to 13/9.
To find the value of sin θ (the sine of θ), we can take the reciprocal of csc θ. So,
sin θ = 1/(csc θ) = 1/(13/9) = 9/13.

A group of students in the book club are debating whether high school juniors or seniors
spend more time on homework. A random sampling of juniors and seniors at the local high
school were surveyed about the average amount of time they spent per night on homework.
The results are listed in the table below.
Average Amount of Time on Homework Per Night (in minutes)
Juniors 125 90 95
80 100 100 120- 85 95 120 95 85
Seniors 135 70 65 100 35 175 80 80 90 65 120 60
Part A. Calculate and compare the measures of center for the data sets.
Part B. Calculate and compare the variability in each distribution.
Part C. Does the data support juniors or seniors spending more time on homework?
Explain your reasoning.
Mean (Juniors) = Sum / number of data points = 1085 / 12 ≈ 90.42
Median (Juniors) = (95 + 95) / 2 = 95
Mean (Seniors) = Sum / number of data points = 1095 / 12 ≈ 91.25
Median (Seniors) = (80 + 80) / 2 = 80
How to solve for the median of centerJuniors: 125, 90, 95, 80, 100, 100, 120, 85, 95, 120, 95, 85
First, sort the data: 80, 85, 85, 90, 95, 95, 95, 100, 100, 120, 120, 125
Sum = 1085
Mean (Juniors) = Sum / number of data points = 1085 / 12 ≈ 90.42
Median (Juniors) = (95 + 95) / 2 = 95
Seniors: 135, 70, 65, 100, 35, 175, 80, 80, 90, 65, 120, 60
First, sort the data: 35, 65, 65, 70, 80, 80, 90, 100, 120, 120, 135, 175
Sum = 1095
Mean (Seniors) = Sum / number of data points = 1095 / 12 ≈ 91.25
Median (Seniors) = (80 + 80) / 2 = 80
Variability
Juniors:
Range = max - min = 125 - 80 = 45
Seniors:
Range = max - min = 175 - 35 = 140
C. Based on the mean and median, it appears that seniors spend slightly more time on homework on average (mean ≈ 91.25) compared to juniors (mean ≈ 90.42).
However, the median time spent for seniors (80 minutes) is less than that of juniors (95 minutes), indicating that the data for seniors might be skewed by some outliers.

Fatoumata has a bag that contains orange chews, apple chews, and watermelon chews. She performs an experiment. Fatoumata randomly removes a chew from the bag, records the result, and returns the chew to the bag. Fatoumata performs the experiment 29 times. The results are shown below: A orange chew was selected 6 times. A apple chew was selected 10 times. A watermelon chew was selected 13 times. Based on these results, express the probability that the next chew Fatoumata removes from the bag will be orange or apple as a percent to the nearest whole number
The probability that the next chew Fatoumata removes from the bag will be orange or apple, rounded to the nearest whole number, is approximately 55%.
To calculate the probability that the next chew Fatoumata removes from the bag will be either orange or apple, we need to determine the total number of times an orange or apple chew was selected.
From the given results, Fatoumata selected an orange chew 6 times and an apple chew 10 times. To find the probability, we add the number of occurrences for each chew:
Orange chews: 6 times
Apple chews: 10 times
Total occurrences of orange or apple chews: 6 + 10 = 16
Fatoumata performed the experiment a total of 29 times. So, the probability of selecting an orange or apple chew can be calculated as:
Probability = (Total occurrences of orange or apple chews) / (Total number of experiments) = 16 / 29
To express this probability as a percentage, we multiply the probability by 100:
Probability (as a decimal) = 16 / 29 ≈ 0.5517
Probability (as a percentage) = 0.5517 × 100 ≈ 55.17%
Therefore, the probability that the next chew Fatoumata removes from the bag will be orange or apple, rounded to the nearest whole number, is approximately 55%.

Explain what is meant by a positive relationship between two variables and a negative relationship between two variables. Give an example of a situation in which you would expect to find a positive relationship and when you would expect to find a negative relationship.
Answer: A positive relationship between two variables means that as the value of one variable increases, the value of the other variable also increases. In other words, there is a direct association or correlation between the two variables. Graphically, a positive relationship is represented by an upward-sloping line or curve.
For example, let's consider the relationship between studying time and exam scores. In general, if a student spends more time studying for an exam, their exam score is likely to increase. This implies a positive relationship between studying time and exam scores.
On the other hand, a negative relationship between two variables means that as the value of one variable increases, the value of the other variable decreases. In this case, there is an inverse association or correlation between the two variables. Graphically, a negative relationship is represented by a downward-sloping line or curve.
For instance, let's consider the relationship between hours of sleep and levels of fatigue. As the number of hours of sleep decreases, the level of fatigue tends to increase. This indicates a negative relationship between hours of sleep and levels of fatigue.
It's important to note that these examples describe typical scenarios, but individual variations and other factors can also influence the relationships between variables.
The cost of packing a box of chocolates is given by 1/4 x^2, where x is the number of chocolates (a box can never have fewer than 3 chocolates). If the weight of a box of
chocolates is given by x + 2, what is the cost of packaging per weight unit
The cost of packaging per weight unit is given by (1/4) (x / (x + 2)) x.
We have,
To find the cost of packaging per weight unit, we need to calculate the cost of packaging (C) and divide it by the weight of the chocolates (W).
Given:
Cost of packaging (C) = 1/4 x²
Weight of chocolates (W) = x + 2
To find the cost of packaging per weight unit, we can express it as C/W.
Substituting the given expressions:
C/W = (1/4 x²) / (x + 2)
To simplify the expression, we can first simplify the numerator:
C/W = (1/4 x²) / (x + 2)
= (1/4) x (x² / (x + 2))
= (1/4) x (x(x) / (x + 2))
= (1/4) x (x / (x + 2)) * x
Now, we can rewrite the expression as:
C/W = (1/4) x (x / (x + 2)) x
Therefore,
The cost of packaging per weight unit is given by (1/4) (x / (x + 2)) x.

Step-by-step explanation:
Slope = rise/run. The equation is (y2-y1)/(x2-x1).
So let's pick 2 points. There are pink dots on (-2,2) and (6,-4), so we'll use those points.
slope = (2-(-4))/(-2-6)
slope = (2+4)/(-2-6)
slope = (6)/-8, which we can simplify by dividing the numerator and denominator each by 2.
slope = -3/4
Just as a quick check, this makes sense because as x increases, y decreases so we should expect the slope to be negative.
Answer:

The solution for X is X ≈ [tex]tan^{(-1)(0.7429)[/tex], which is approximately 0.6619 radians or approximately 37.89 degrees.
Given: 1 secX + 3 = cosX + tanX (2 + sinX)
To simplify the equation, let's express secX and tanX in terms of sinX and cosX:
1/cosX + 3 = cosX + sinX/cosX (2 + sinX)
Now, multiply both sides by cosX to eliminate the denominators:
[tex]1 + 3cosX = cos^2X + sinX(2 + sinX)[/tex]
Expanding the equation:
[tex]1 + 3cosX = cos^2X + 2sinX + sin^2X[/tex]
Since [tex]sin^2X + cos^2X[/tex] equals 1 (based on the Pythagorean identity), we can substitute it into the equation:
[tex]1 + 3cosX = 1 + 2sinX + sin^2X[/tex]
Rearranging the terms:
[tex]3cosX = 2sinX + sin^2X[/tex]
Now, let's express cosX in terms of sinX using the Pythagorean identity:
cosX = √(1 - [tex]sin^2X[/tex])
Substituting this into the equation:
3√(1 - [tex]sin^2X) = 2sinX + sin^2X[/tex]
Squaring both sides to eliminate the square root:
[tex]9(1 - sin^2X) = (2sinX + sin^2X)^2[/tex]
Expanding the right side:
[tex]9(1 - sin^2X) = (2sinX)^2 + 2(2sinX)(sin^2X) + (sin^2X)^2\\9 - 9sin^2X = 4sin^2X + 4sin^3X + sin^4X[/tex]
Rearranging the terms:
[tex]sin^4X + 4sin^3X + 4sin^2X + 9sin^2X - 9 = 0[/tex]
Combining like terms:
[tex]sin^4X + 4sin^3X + 13sin^2X - 9 = 0[/tex]
Unfortunately, this equation does not have a simple algebraic solution. It needs to be solved numerically or graphically. Using numerical methods or a graphing calculator, we can find that one solution to this equation is sinX ≈ 0.7429.
Taking the inverse tangent (arctan) of both sides, we have:
X = arctan(0.7429)
Therefore, the solution for X is X ≈ t[tex]an^{(-1)}(0.7429)[/tex], which is approximately 0.6619 radians or approximately 37.89 degrees.

Ashley got a prepaid debit card with $30 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 13 cents per yard. If after that purchase there was $25.06 left on the card, how many yards of ribbon did Ashley buy?
Answer:
38 yards
Step-by-step explanation:
First, subtract to find out how much money was spent.
30 - 25.06
= 4.94
Then divide to find out how many groups of $0.13 are in $4.94.
4.94 ÷ .13
= 38
Ashley bought 38 yards of ribbon.
38 × .13 = 4.94
4.94 + 25.06 = 30
This answer does not consider tax at all. Because it wasn't mentioned in the question and it complicates the problem. So probably don't worry about tax. Unless your teacher /book/program said to consider it. I can edit the answer.
Also, if they said to write an equation:
Let x = yards of ribbon
30 - .13x = 25.06
subtract 30
-.13x = -4.94
divide by -.13
x = 38
Sarah wants to buy a new laptop. Store A is currently selling the laptop for $1,640 with an additional 20% off. Store B is selling the laptop for $1,500 with an additional 10% off. Which store offers a better deal?
Answer:
Store A
Step-by-step explanation:
If an item is 20% off, then you pay 80% of the price.
If an item is 10% off, then you pay 90% of the price.
Store A
80% of $1640 = 0.8 × $1640 = $1312
Store B
90% of $1500 = 0.9 × $1500 = $1350
Answer: Store A
Answer:
Store A
Step-by-step explanation:
Store A offers a 20% discount which is equivalent to 0.20 x $1,640 = $328.
The laptop is therefore sold for $1,640 - $328 = $1,312 at Store A.
Store B offers a 10% discount which is equivalent to 0.10 x $1,500 = $150.
The laptop is therefore sold for $1,500 - $150 = $1,350 at Store B.
Therefore, Store A offers a better deal at $1,312 compared to Store B at $1,350.

Which graph has the same end behavior as f(x)=(10x^(3)+x^(2)+3)/(2x^(2)+1)?
The graph that has the same end behavior as f(x)= (10x³+x²+3)/(2x²+1) is Option A. See the attached.
What is the end behavior of the above graph?the end behavior of the graph of f(x) is:
As x → +∞ , f(x) → +∞ (approaches positive infinity).
As x → -∞, f(x) → -∞ (approaches negative infinity).
End behavior of a function f defines the behavior of the function's graph at the "ends" of the x- axis.
In other words, the end behavior of a function explains the graph's trend when we look at the right end of the x-axis (as x approaches +∞) and the left end of the x -axis (as x approaches - ∞ ).
