Alisa uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Choose one of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Identify which brand was chosen as part of your answer. Use the volume formula, V= l x w x h
Answers
The amount it will cost Alisa to fill the volleyball court using sand from Brand A with a unit rate of $1/12 per lb and a mass of sand of 135200 lbs is $11266.\(\overline{6}\)
What is a unit rate?A unit rate is the rate or amount for one (unit) of an item.
The mass of sand that fills one cubic ft. = 100 pounds
The volume of sand required to fill the volleyball court can be found using the formula; V = l × w × h
Where:
l = The length of the volleyball court = 52 ft
w = The width = 26 ft
h = The height = 1 ft
Therefore; V = 26 ft × 52 ft × 1 ft = 1352 ft³
The mass of sand required, m = 100 lbs × 1352 = 135200 lbs
The unit rate for Brand A = $(5/60)/lb = $(1/12)/lb
The unit rate for Brand B = $(12/150)/lb = $0.08 per lb
The cost of filling the volleyball court using Brand A, C₁, is therefore;
Cost of Brand A, C₁ = $(1/12)/lb × 135200 lb = $11266.\(\overline{6}\)The cost using Brand B, C₂ = $0.08/lb × 135200 lb = $10816The possible parts of the question missing, obtained from a similar question online includes;
Alisa is at the hardware store to buy sand to set up a volleyball court in her back yard.
The dimension of a beach volleyball court = 26 feet by 52 feet
The depth of filling of the sand = 1 ft deep
The prices of the sands are;
60 lbs of sand A = $5
150 lbs of sand B = $12

A coin is flipped eight times where each flip comes up either heads or tails. How many possible outcomes (8 pts)
Answers
Answer:
the possible outcomes contain the same number of heads and tails are 70.
tell me if i am right
For each coin flip, there are 2 possible outcomes (heads or tails), so for 8 flips, there are \(2^8\) = 256 possible outcomes.
When flipping a coin, there are two possible outcomes: heads or tails. So, for one flip, there are two possibilities. For two flips, there are two possibilities for the first flip and two possibilities for the second flip, making a total of 2x2=4 possible outcomes.
For three flips, there are two possibilities for the first flip, two for the second flip, and two for the third flip, making a total of 2x2x2=8 possible outcomes.
Similarly, for four flips, there are 2x2x2x2=16 possible outcomes, and for five flips, there are 2x2x2x2x2=32 possible outcomes.
Continuing this pattern, for eight flips, there are 2x2x2x2x2x2x2x2 = 256 possible outcomes.
This can also be calculated using the formula for combinations, which is \(n! / (r!(n-r)!)\) where n is the number of total flips (in this case, 8) and r is the number of heads that we want to get.
For example, to find the number of outcomes where we get exactly 3 heads and 5 tails, we would use the formula:
\(8! / (3!5!) = 56\)
So, there are 56 possible outcomes where we get exactly 3 heads and 5 tails.
In summary, for each coin flip, there are 2 possible outcomes (heads or tails), so for 8 flips, there are \(2^8 = 256\) possible outcomes.

B. y−3=13(x+1)
C. y+2=−3(x−1)
D. y−5=3(x−1)
Answers
Answer:
c. \( y + 2 = -3(x - 1) \)
Step-by-step explanation:
By using a point on the line and the slope, we can determine the equation, in point-slope form, that is graphed in the figure.
Using two points, (1, -2) and (0, 1),
\( slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-2)}{0 - 1} = \frac{3}{-1} = -3 \)
m = -3
Using a point, (1, -2) and the slope (m), we can create an equation for the graph in point-slope form, by substituting x1 = 1, y1 = -2 and m = -3 in \( y - y_1 = m(x - x_1) \).
Thus, we would have:
\( y -(-2) = -3(x - 1) \)
\( y + 2 = -3(x - 1) \)
The equation that is graphed in the figure is:
✔️\( y + 2 = -3(x - 1) \)

In a sample of 49 games in 2002, the average duration of a game was 2 hours and 58 minutes with a standard deviation of 35 minutes. A similar survey in 2003 of 52 games found that the average duration was 2 hours and 40 minutes with a standard deviation of 24 minutes. When testing the hypothesis (at the 5% level of significance) that the variance has been reduced, what is the test statistic? (please round your answer to 2 decimal places)
Answers
This code will print the test statistic for the variance test statistic is 17.99.
The test statistic for the hypothesis test is the ratio of the sample variances, s1^2 / s2^2. In this case, the sample variances are 35^2 / 24^2 = 17.99. The p-value for this test statistic is very small, so we can reject the null hypothesis and conclude that the variance has been reduced.
**The code to calculate the above:**
```python
import math
def test_statistic(s1, s2):
"""Returns the test statistic for the variance test."""
return s1 ** 2 / s2 ** 2
s1 = 35 ** 2
s2 = 24 ** 2
t = test_statistic(s1, s2)

In reference to line items, how many permutations are possible with the letters "ABC"?
Answers
So there are 6 permutations possible with the letters "ABC". These are: ABC, ACB, BAC, BCA, CAB, CBA.
Permutations are a way of arranging objects in a specific order. The number of permutations of a set of n distinct objects is given by n!, where n! denotes the factorial of n.
In the case of the letters "ABC", there are three distinct objects: A, B, and C. Therefore, the number of permutations possible with these letters is:
3! = 3 x 2 x 1 = 6
This means that there are 6 possible ways of arranging the letters "ABC" in a specific order. These permutations are:
ABC
ACB
BAC
BCA
CAB
CBA
To see why there are 6 possible permutations, consider the first position. There are three letters to choose from, so there are three possible choices for the first position. Once the first letter is chosen, there are two letters left to choose from for the second position. Finally, there is only one letter left to choose from for the third position. Therefore, the total number of permutations is:
3 x 2 x 1 = 6
In summary, the number of permutations of a set of n distinct objects is given by n!, and in the case of the letters "ABC", there are 3! = 6 possible permutations: ABC, ACB, BAC, BCA, CAB, and CBA.

Please help!!! Angles!
Answers
Answer:
m∠JKM = 63°
m∠MKL = 27°
Step-by-step explanation:
Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.
\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)
Solve the equation for x:
\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)
We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,
m∠JKM = 12(5) + 3 = 60 - 3 = 63°
m∠MKL = 6(5) - 3 = 30 - 3 = 27°

Answers
The approximate probability that the total score is at least 375 when a fair six-sided die is rolled 100 times is (d) 0.4420.
When a fair six-sided die is rolled, the random variable X represents the outcome. The mean (μX) of X is 3.5, and the standard deviation (σX) is 1.71.
To find the probability that the total score is at least 375 when the die is rolled 100 times, we can use the Central Limit Theorem. According to the theorem, the sum of a large number of independent and identically distributed random variables approximates a normal distribution.
In this case, the sum of the outcomes of 100 rolls of the die follows a normal distribution with a mean of μX multiplied by the number of rolls (100) and a standard deviation of σX multiplied by the square root of the number of rolls (10). Therefore, the approximate probability can be calculated by finding the probability that the sum is greater than or equal to 375.
Using a normal distribution table or a calculator, we can find that the approximate probability is 0.4420, which corresponds to answer (d). This means that there is a 44.20% chance that the total score will be at least 375 when the die is rolled 100 times.

ANALYZE Which key feature of the graph represents Aidan's break-even point (profit = 0)? Explain how to use your graph to find the most
accurate value for this feature.
Answers
Answer:
P(x) = $31x - $840
Step-by-step explanation:
Let x be the number of bicycles. The total cost for purchasing and repairing the bikes is $47x, plus a one-time purchase of $840 for a workshop and tools. Total cost, C is therefore:
C(x) = $47x + $840
We learn Aidan sells the bikes for $75 each. Total revenue, R, is:
R(x) = $75x
Profit, P, would be the difference of revenue, R, and costs, C:
P(x) = R(x) - C(x) or $75x -($47x + $840)
P(x) = $75x -$47x - $840
P(x) = $31x - $840
P(x) represents the total profit for x bicycles.
See the attached graph. Note the key features of the graph are the breakeven (27 bikes) and the initial investment (-$840). We can find the breakeven point by looking for the value of x when the profits are $0. A more accurate determination can be found by solving the equation we developed for the case in which P(x) = $0:
P(x) = $31x - $840
0 = $31x - $840 for P(x) = 0 (breakeven)
$31x = $840
x = 27.1 units. We need to round to 27 units since 0.1 of a bicycle makes no sense in this context.
