Answer:
Step-by-step explanation:
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.

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

a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.say true or false I need it now pls
That's TRUE but I predict by the time your grandchildren are in school we'll have stop teaching that geometric things are sets of points. That's a bad way to think about things.
Its True a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.
Given that,
A circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle. Whether it's true or false is to be justified in a statement.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here, the distance of the point on the circumference of the circle has a fixed distance from the center.
Thus, it's true a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.

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

What is the percent of change from 2000 to 200
Answer: 90% decrease
Step-by-step explanation: First determine whether the number is increasing or decreasing. Since it changes from 2,000 to 200, it's going down so it's decreasing.
Now to find the percent decrease, we divide the
amount of change by the original number.
The amount of change is the difference between the two numbers
which in this case is 2,000 - 200 and the original number is 2,000.
[tex]So[/tex] [tex]we[/tex] [tex]have[/tex] [tex]\frac{2,000 - 200}{2,000}[/tex].
2,000 - 200 is 1,800.
So we're left with 1,800/2,000 and dividing
2,000 into 1,800 gives us 0.9.
Remember however that our problem is
asking for a percent, not a decimal.
So we need to write 0.9 as a percent and we can do
that by multiplying it by 100 and adding the percent sign.
So 0.9 becomes 90%.
So when a number changes from 2,000 to 200,
it has decreased by 90%.

A music store bought a CD set at a cost of $20. When the store sold the CD set, the percent markup was 40%. Find the selling price.
Answer:
Selling price = $28
Step-by-step explanation:
Cost price = $20
Selling price = ?
Percent markup = 40%.
Percentage markup is the difference between a products selling price and cost as a percentage to the cost.
% mark up = (selling price - cost price) / (cost price) * 100
[(Selling price - 20) / 20 ] * 100 = 40
40 / 100 = (selling price - 20) / 20
0.4 * 20 = selling price - 20
8 = selling price - 20
Selling price = $(8 + 20)
Selling price = $28.
The selling price was $28
Answer: The selling price is $28
Step-by-step explanation: If the CD set was bought at the cost of $20 and sold at a selling price of $20 plus 40% (or 0.4), then we should start by calculating the value of 40% of the cost price, which would then be added to the cost price to arrive at the selling price.
The calculation is as follows;
Mark up = 20 x 0.4
Mark up = 8
Selling price = Cost price + Mark up
Selling price = 20 + 8
Selling price = 28
Therefore the selling price is $28

Your teacher will give you a drawing of the Apollo Lunar Module. It is drawn at a scale of 1 to 50.
The "legs" of the spacecraft are its landing gear. Measure the legs on the drawing to find the actual length of
each leg on the sides.
After measuring and solving for the actual length, write your answer to the nearest 10 centimeters.
Final answer:
To find the actual length of each leg of the Apollo Lunar Module, use the given scale of 1 to 50. Measure the length of the leg on the drawing and multiply it by the scale factor.
Explanation:
To find the actual length of each leg of the Apollo Lunar Module, we need to use the given scale of 1 to 50. This means that 1 unit on the drawing represents 50 units in real life. First, measure the length of the leg on the drawing. Let's say it measures 3 centimeters. To find the actual length, multiply the measured length by the scale factor: 3 cm x 50 = 150 centimeters. Therefore, each leg of the Apollo Lunar Module is 150 centimeters long.
