The effective price paid by the company after taking account of hedging would be $63.50, which is the August futures price on July 1. Calculate the profit or loss on the futures contracts and subtract that from the spot price on July 1, to determine the effective.
By entering into futures contracts on March 1, the company was able to lock in the price of $59 for the commodity, when the spot price was $60 and the futures price was $59, the difference between the futures price and the spot price on March 1 was $1 ($60 - $59), so the company had to pay an extra $1 per unit to hedge its purchase.
When the spot price increased to $64 on July 1, the company was still able to purchase the commodity at the lower hedged price of $59, plus the cost of the futures contract, which resulted in an effective price of $63.50. Overall, hedging helped the company mitigate the risk of price volatility and ensured a more predictable cost for the commodity purchase.
Effective price = Spot price - Profit from futures contracts
Effective price = $64 - $0.50(The difference between the futures price and the spot price on July 1 was $0.50 ($64 - $63.50))
Effective price = $63.50 per unit
Therefore, the effective price paid by the company after taking into account hedging was $63.50 per unit.

Gregor Mendel (1822–1884), an Austrian monk, is considered the father of genetics. Mendel studied the inheritance of various traits in pea plants. One such trait is whether the pea is smooth or wrinkled. Mendel predicted a ratio of 3 smooth peas for every 1 wrinkled pea. In one experiment, he observed 423 smooth and 133 wrinkled peas. Assume that the conditions for inference were met. Carry out a chi-square goodness-of-fit test based on Mendel’s prediction. What do you conclude?
We conclude that the data are consistent with Mendel's prediction of a 3:1 ratio of smooth to wrinkled peas.
Understanding Chi-squareTo carry out a chi-square goodness-of-fit test, we need to calculate the expected number of smooth and wrinkled peas based on Mendel's prediction of a 3:1 ratio.
The total number of peas observed in the experiment is:n = 423 + 133 = 556The expected number of smooth peas is 3/4 of the total number of peas, and the expected number of wrinkled peas is 1/4 of the total number of peas.
Therefore, we have: Expected number of smooth peas = 3/4 × 556 = 417Expected number of wrinkled peas = 1/4 × 556 = 139
We can now calculate the chi-square statistic as follows:chi-square = Σ[(observed - expected)² / expected]where the sum is taken over the two categories (smooth and wrinkled).
For the observed values of 423 smooth and 133 wrinkled peas, we have: chi-square = [(423 - 417)^2 / 417] + [(133 - 139)^2 / 139]= 0.84 + 0.84= 1.68
The degrees of freedom for this test are (number of categories - 1), which is 2 - 1 = 1.
Using a significance level of 0.05 and a chi-square distribution table with 1 degree of freedom, we find that the critical value of chi-square is 3.84.
Since our calculated chi-square value of 1.68 is less than the critical value of 3.84, we fail to reject the null hypothesis that the observed frequencies do not differ significantly from the expected frequencies based on Mendel's prediction.
Therefore, we conclude that the data are consistent with Mendel's prediction of a 3:1 ratio of smooth to wrinkled peas.

What is the sum of 2 / 10 + 6/100 not simplified
Answer: 26/100 OR 0.26 (I would put the answer as a fraction)
Step-by-step explanation:
We need both fractions to have the same denominator before we add them. The denominator of 6/100 is 100. The denominator of 2/10 is 10. We need to turn 10 into 100. To do that, we can do 10*10. This gives us 100. However what we do to the bottom must be done to the top therefore we have 20/100 + 6/100
Now the two fractions can be added together. 20/100 + 6/100 = 26/100.
Normally we would simplify this down to 13/50 but if you want it unsimplified 26/100 would be your answer.

The best prediction possible for the number of times you will roll a one number when a 6-sided die is rolled 12 times = (0.167)¹²
Probability:Events occur as the outcome of an experiment. But one cannot be satisfied with these events until a degree of measurement of the likeliness of its occurrence is not provided. Probability is a statistical tool used widely to obtain predictive value.
Here, 6-sided die rolled 12 times.
If a 6-sided die is rolled, possible outcomes are {1, 2, 3, 4, 5, 6}
So, total number of outcomes = 6
So, number of favorable outcomes = 1

Astha's account was greater than the amount of money in Henry's account is:
5700 + 100x > 75x
Why Astha's account was greater?Let's start by finding the total amount of money deposited by Astha and Henry after x weeks.
Astha deposited $100 into her account each week for x weeks, so the total amount she deposited is 100x.
Similarly, Henry deposited $75 into his account each week for x weeks, so the total amount he deposited is 75x.
To find the inequality that represents the situation when the amount of money in Astha's account was greater than the amount of money in Henry's account, we need to compare the total amount of money each of them deposited.
Astha started with $5,700 and deposited $100 each week for x weeks, so the total amount of money in her account after x weeks is:

Answer: B, C and E
Step-by-step explanation: the term growing means the value is increasing, and a number multiplied by 1 gives the same number; therefore in order for that number to increase, it need to be multiplied by a bigger number which is greater than 1, in this case it can not be a number less than 0 like 0.85, so all the number which are greater than 1 in the bracket are correct.
the number before the bracket is the population before increasing, so you can substitute any value for t and try out different outcomes, you will get only B, C and E as number greater than the original number

The value of x that will make a parallel to b is 30. We solved the equation 4x + 2x = 180 and obtained x = 30.
According to the definition of interior consecutive angles, when a transversal intersects two parallel lines, the sum of the measures of the two interior consecutive angles formed on the same side of the transversal is always 180°.
In this case, we are given that lines A and B are parallel, and line q intersects these lines at two distinct points, forming two interior consecutive angles with measures 4x and 2x, respectively.
Since the two angles are consecutive and on the same side of the transversal, their sum is equal to 180°. Therefore, we can set up the following equation
4x + 2x = 180
Simplifying the equation, we get
6x = 180
Dividing both sides by 6, we get

a) The price of the old model is P22,289.
b) The dimensions of the rectangle are 16 by 32.
a) Let x be the price of the old model. According to the problem, the price of the new 32'' LED television is P15,500 less than twice the price of the old model.
This can be expressed as 2x - P15,500 = P29,078. Solving for x, we can add P15,500 to both sides to get 2x = P44,578, and then divide both sides by 2 to get x = P22,289.

a) The resulting true speed of the boat is approximately 5.39 m/s.
b) The compass direction of the boat is 21.8° south of east.
c) The distance downstream the boat will land on the shore if the river is 800 meters wide is 320 meters.
a) To find the true speed of the boat, we can use the Pythagorean theorem. Since the boat's speed is 5 m/s due east and the current's speed is 2 m/s due south, we can treat these as perpendicular vectors. The true speed can be found using the formula:
True Speed = √((5 m/s)² + (2 m/s)²) = √(25 + 4) = √29 ≈ 5.39 m/s
b) To find the compass direction of the boat, we can use the inverse tangent function. The angle θ can be calculated using:
θ = arctan(opposite/adjacent) = arctan(2 m/s / 5 m/s) ≈ 21.8°
Since the boat is headed east and the current is pushing it south, the true direction is 21.8° south of east.
c) To find the distance downstream where the boat will land, we first need to calculate the time it takes to cross the river. The boat's speed across the river (due east) is 5 m/s and the width of the river is 800 meters. The time taken to cross the river is:
Time = Distance / Speed = 800 m / 5 m/s = 160 seconds
Now, we can use the time to find the distance downstream by multiplying the current's speed (2 m/s) by the time:
Distance downstream = 2 m/s × 160 s = 320 meters
So, the boat will land 320 meters downstream from its starting point on the opposite shore.

x / 10 - 2y / 3 = 1.2
(the slashes represent fractions.)
The solution of the given system of equations is x = 3.2 and y = 1.5.
To solve this system of equations, we can use the method of elimination, where we eliminate one of the variables by adding or subtracting the equations.
First, let's eliminate y by multiplying the first equation by 2 and the second equation by 15:
12x/5 + 2y/15 = 4.6 (multiply the first equation by 2)
3x/2 - 10y = 18 (multiply the second equation by 15)
Now we can eliminate y by multiplying the first equation by 5 and adding it to the second equation:
12x + y/5 = 23 (multiply the first equation by 5 and simplify)
12x - y = 54 (subtract the second equation from the previous equation)
Adding the two equations, we get:
24x = 77
Therefore, x = 77/24.
Substituting x = 77/24 into the first equation, we get:

Identify the volume of the composite figure. The figure shows a rectangular prism with a cube removed. The prism is 9 meters long, 8 meters wide, and 3 meters high. The cube has a side of 4 meters
The volume of the composite figure is 152 m³.
How to solve for the volume of the shapeThe volume of a rectangular prism can be found using the formula V = lwh, where l is the length, w is the width, and h is the height.
For the rectangular prism:
V_prism = lwh = 9m * 8m * 3m = 216 m³
For the cube:
V_cube = s^3 = 4m * 4m * 4m = 64 m³
Now, subtract the volume of the cube from the volume of the prism:

Based on the box-and-whisker plot shown below, match each term with the correct value. PLEASE ANSWER QUICKLY!!!
The value of the median is 18. The range of this plot is 6. The 25th percentile is 17 and the 75th percentile is 20. The interquartile range is 3.
We are given a box-and-whisker plot and we have to find the correct value of the median, range, 25th percentile, 75th percentile, and inter-quartile range with the help of this box-and-whisker plot.
We find the median with the help of the box. The line which splits the box into two halves is the median for the given data. Therefore, the median will be 18. To find the range, we subtract the minimum value from the maximum value. The minimum value is 15 and the maximum value is 21. Therefore, the range will be (21 - 15) = 6.
From the plot, we can see that the 25th percentile is 17, Q1, and the 75th percentile is 20, Q3. Now, we have to find the interquartile range. To find the interquartile range, we subtract Q1 from Q3. Therefore, our interquartile range will be (20 -17) = 3.

Step-by-step explanation:
What is the maximum height of of Anna's golf ball? The equation is y=x−0. 04x2
The maximum height of Anna's golf ball is approximately 7.81 units.
Find the maximum height of Anna's golf ball with equation y=x−0. 04x2
The equation y = [tex]x - 0.04x^2[/tex] represents the height of Anna's golf ball, where x is the horizontal distance the ball has traveled.
To find the maximum height of the ball, we need to determine the vertex of the parabolic equation. The x-coordinate of the vertex can be found using the formula x = -b/2a, where a = -0.04 and b = 1.
x = -b/2a = -1/(2(-0.04)) = 12.5
So, the maximum height of the ball occurs when it has traveled a horizontal distance of 12.5 units. To find the maximum height, we substitute x = 12.5 into the equation:
[tex]y = 12.5 - 0.04(12.5)^2 = 7.81[/tex]

Using the formula V = k*T/P to get the volume, the required volume in the given situation is 1.77L.
What is volume?The measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units.
Volume and the notion of length are connected.
The area that any three-dimensional solid occupies is known as its volume.
These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
So, the volume can be obtained using the equation:
V = k*T/P
The value of the constant k is:
K = PV/T = 16N/cm²*2.2L/340K = 0.104N*L*K⁻¹*cm⁻²
We can now determine the volume when:
T = 408 K
P = 24 N/cm²
V = k*T/P = 0.104N*L*K⁻¹*cm⁻²*408K/21Ncm = 1.77L
Therefore, using the formula V = k*T/P to get the volume, the required volume in the given situation is 1.77L.
