Oscar and Eli can sell 368 1-cup servings of lemonade because there are 16 cups in 1 gallon, and they have 23 gallons of lemonade.
Explanation:Calculating Servings of LemonadeOscar and Eli have prepared 23 gallons of lemonade and want to know how many 1-cup servings they can sell. First, we need to know the equivalent of gallons to cups. There are 16 cups in 1 gallon. Therefore, we multiply 23 gallons by 16 cups per gallon to find the total number of cups available:
23 gallons x 16 cups/gallon = 368 cups. Thus, they can sell 368 1-cup servings of lemonade.
To summarize the conversion:
1. Identify the conversion rate between gallons and cups (1 gallon = 16 cups).
2. Multiply the total gallons of lemonade by the conversion rate to get the total cups (23 gallons x 16 cups/gallon).
An Apple producer sells their product in bags that each contain 16 apples. These apples have a mean weight of 80 grams and a standard deviation of 5 grams. Suppose that each bag represents an SRS of apples, and we calculate the sample mean weight of the apples in each bag. What is the mean and standard deviation of the sampling distribution?
Mean: 80 grams
Standard Deviation: 1.25 grams
The mean stays the same.
How to find standard deviation in this case would be:
SD divided by the squareroot of the sample.
So, 5/[tex]\sqrt{16}[/tex] = 1.25

Step-by-step explanation:
Josie found a small bird bath at a garage sale. The bird bath has a circular opening with a radius of 10 cm, as shown in the diagram below. Using 3.14 for pi, Josie calculates that the water in the small bird bath has 314 cm2 of surface area. Josie lives in a wooded area with lots of birds, so she plans to use the bird bath she found as a scale model to build a much larger bird bath. If she doubles the dimensions of the scale model, how many square centimeters of surface area will the larger bird bath have for bathing?
Answer: 1256cm
Step-by-step explanation:
Final answer:
When Josie doubles the radius of the bird bath to build a larger one, the new surface area will be 1256 cm², as surface area quadruples when doubling the radius of a circle.
Explanation:
Josie calculated that the surface area of her small bird bath with a radius of 10 cm is 314 cm^2. If she doubles the dimensions for a larger bird bath, the new radius will be 20 cm. To find the surface area of the larger bird bath, we use the formula for the area of a circle, A = πr².
Plugging in the new radius:
A = 3.14 × (20 cm)^2
A = 3.14 × 400 cm^2
A = 1256 cm2
This means the surface area for the larger bird bath Josie plans to build will have 1256 cm^2 for bird bathing. This calculation demonstrates how the surface area of a circle quadruples when the radius is doubled, which is consistent with the principle that surface area scales with the square of the dimension changes.

For the following exercises, use the table of values that represent points on the graph of a quadratic function. By determining the vertex and axis of symmetry, find the general form of the equation of the quadratic function.
Answer:
y = x² + 2x + 1
Step-by-step explanation:
Same y value at x = -2 & x = 0
So line of symmetry is at:
x = (-2+0)/2
x = -1
Vertex: (-1,0)
y = a(x - -1)² + 0
y = a(x + 1)²
At x = 1, y = 4
4 = a(1 + 1)²
4 = 4a
a = 1
y = (x + 1)²
y = x² + 2x + 1
The general form of the equation of the quadratic function is x² + 2x + 1
The formula expressing the equation of the quadratic function will be expressed as:
y = a(x -h)² + k
From the table shown, we can see that the y-values are the same at where x = -2 and 0
Get the line of symmetry:
[tex]x =\frac{-2+0}{2}\\x=\frac{-2}{2} \\x=-1[/tex]
We can see that when x = -1, y = 0. Hence the vertex will be at (-1, 0)
h = -1
k = 0
Substitute into the formula y = a(x -h)² + k
y = a(x -(-1))² + 0
y = a(x+1)²
From the table at where x = 1, y = 4. On substituting to get "a" we have:
4 = a(1+1)²
4 = 4a
a = 1
Get the required quadratic function by substituting the parameters into the general formula as shown:
y = a(x -h)² + k
y = 1(x +1)² + 0
y = (x+1)²
y = (x+1) (x+1)
y = x² + x +x + 1
y = x² + 2x + 1
Hence the general form of the equation of the quadratic function is x² + 2x + 1

The answer to your question is 42°
Step-by-step explanation:

m∠BOC = 6x - 6
m∠AOB = 5x + 8
m∠BOC = ?
Process
We know that the segments OA ⊥ OC so they are complementary angles.
1.- The sum of complementary angles equals 90°
m∠BOC + m∠AOB = 90°
2.- Substitution
6x - 6 + 5x + 8 = 90°
3.- Solve for x
6x + 5x = 90 + 6 - 8
4.- Simplify
11x = 88
5.- Result
x = 88/11
x = 8
6.- Calculate m∠BOC
m∠BOC = 6(8) - 6

The cruising speed of the bullet train will be at least 170 miles per hour. Use s to represent the train's cruising speed (in miles per hour). Write an inequality to represent the situation
Answer:
s ≥ 170
Step-by-step explanation:
The problem raises the following statement: "The cruising speed of the bullet train will be at least 170 miles per hour"
Which means that the train has a speed of 170 miles for now or higher, knowing this we can pose the inequality.
Knowing that "s" is the train's cruising speed (in miles per hour), we have to:
s ≥ 170
This would be the inequality that the statement represents.
The inequality representing the bullet train's cruising speed being at least 170 miles per hour is s ≥ 170.
The situation described involves finding an inequality for the train's cruising speed. To represent the train's cruising speed in miles per hour, we use the variable s.
Given that the cruising speed of the bullet train will be at least 170 miles per hour, we need an inequality that expresses this condition.
The inequality is:
s ≥ 170
This means that the cruising speed s can be 170 miles per hour or higher.

Column 1 has the entries run, do not run, and total. Column 2 is called lift weights, and it has the values 40, blank, and 65. Column 3 is captioned "do not lift weights" and has entries blank, x, and blank. Column 4 is called total and has the entries 75, blank, and 120.
As per the given information, the required solution would be as:
The number of people who do not run or lift weights by first determining that 55 individuals do not lift weights and 35 people run but do not lift weights. When you subtract 35 from 55, you get 20 people who don't do either.
Thus, the required value of a number of people is 20 who don't do either.

The number x represents the number of people who do not run and do not lift weights. To calculate x, subtract the number of people who lift weights from the total number, then subtract the number of people who run and lift weights.
Explanation:To find the number that x represents, we can use the information given in a table with a row and column structure. From the total number of people (120) and the number of people that lift weights (65), we deduct the number that run and lift weights (40), leaving us with the number of people who either do not run or do not lift weights.
The total number of people that run is given as 75. Therefore, the number who do not run is 120 - 75 = 45. We know that 65 people lift weights, so by subtraction, 120 - 65 gives us the total number of people who do not lift weights.
Now, using the total number of people who do not lift weights, we can calculate the value of x, which represents the number of people who do not run and also do not lift weights. Subtracting the number of people who run but do not lift weights from the total number who do not lift weights gives us:
Number of people who do not lift weights = Total number of people - Number of people who lift weights
Number of people who do not lift weights = 120 - 65 = 55
Therefore, x equals 55 - 40, since 40 is the number of people who run and lift weights.
x = 55 - 40 = 15

Initial investment (PV)= $100
Number of periods (n)=42 years
Interest rate (i)= 1.75%

Which is the better buy, 12 ounces for $7.50 or 1 pound for $9.00? Explain your reasoning.
To determine the better buy, compare the cost per ounce for each option. The second option of 1 pound for $9.00 is the better buy with a lower cost per ounce.
Explanation:To determine which option is the better buy, we need to compare the cost per ounce for each option.
The first option is 12 ounces for $7.50. To find the cost per ounce, we divide the total cost ($7.50) by the number of ounces (12), giving us a cost of $0.625 per ounce.The second option is 1 pound for $9.00, which is equivalent to 16 ounces. To find the cost per ounce, we divide the total cost ($9.00) by the number of ounces (16), giving us a cost of $0.5625 per ounce.Therefore, the second option of 1 pound for $9.00 is the better buy as it has a lower cost per ounce.
