The unit price for a piece of cheese is $0.11 per pound.

To find the unit price, we need to divide the total cost by the total weight. In this case, we have 1.24 pounds of cheese that costs $11.25.

So, we can set up a proportion

1.24 pounds / $11.25 = x pounds / $1

To solve for x, we can cross-multiply

1.24 pounds * $1 = $11.25 * x pounds

1.24 = $11.25 * x

x = 1.24 / $11.25

x = 0.11

So, the unit price is $0.11 per pound.

The center will be on the line segment CA because, as we already know, a circle's diameter is a chord that passes through its center.

Therefore, the answers are CA and diameter.

we have that in the question, a circle with center 'O' is passing through three A, B and C, where ∠B is a right angle.

In the circumscribed circle, we have the converse of the Thales' theorem, which states that -

if A, B, and C are distinct points on a circle where angle ∠ABC is a right-angle, then the line AC will be a diameter of the circle.

The given information is drawn in the attached figure.

Applying the converse of Thales' Theorem, we have AC will be a diameter of the circle.

As the longest side (hypotenuse) of a right-angled triangle is the opposite side of the right-angle, CA is the longest side of ABC.

The longest side of the triangle equals the diameter of the circle because CA is likewise a diameter of the circle.

Thus, the center will lie on the line segment CA and the longest side of the triangle is equal to the diameter of the circle.

Step-by-step explanation:

its linear because the data shows a straight line:)

Answer:

Linear

Step-by-step explanation:

linear equation forms a straight line on the graph. A nonlinear equation forms a curve on the graph.

The answer is "The IQR is the best measure of variability, and it equals 7. because the best measure of variability for the data is the IQR, and its value is 7

A linear function is defined as a function that has either one or two variables without exponents. It is a function that graphs to a straight line.

The given plot displays the distribution of the number of roses purchased per day at a grocery store. The best measure of variability for this data would be the interquartile range (IQR) since it is robust to outliers and provides a measure of the spread of the middle 50% of the data.

To calculate the IQR, we need to find the first quartile (Q1) and the third quartile (Q3). Q1 is the median of the lower half of the data, and Q3 is the median of the upper half of the data.

From the plot, we can see that there are a total of 11 data points: one at 1, two at 2, three at 6, three at 7, two at 8, and three at 9. The median (Q2) is 7 since it is the middle value when the data are arranged in order.

To find Q1, we need to find the median of the lower half of the data. Since there is one data point below 6 and three data points at 6, the lower half of the data consists of four points: 1, 2, 6, and 6. The median of this set is (1+2)/2 = 1.5.

To find Q3, we need to find the median of the upper half of the data. Since there are two data points at 8 and three data points at 9, the upper half of the data consists of five points: 8, 8, 9, 9, and 9. The median of this set is (8+9)/2 = 8.5.

Therefore, the IQR is Q3-Q1 = 8.5-1.5 = 7.

Therefore, the answer is "The IQR is the best measure of variability, and it equals 7. because the best measure of variability for the data is the IQR, and its value is 7

It will take approximately 25 years for $7,000 to double in an account that pays 2.8% simple interest.

The 70 rule is a helpful shortcut for calculating the number of years it will take an investment to double in value using simple interest. The formula is 70 divided by the interest rate.

In this case, we have an interest rate of 2.8%, so we can calculate that it will take approximately 70/2.8 = 25 years for $7,000 to double in value.

The minimum amount of fencing Mendel will need to enclose 2500 m² = 317 meters

Let's assume that x represents the length of and y represents the width of the rectangular garden.

Using the formula for tha area of rectangle, the area of the garden would be,

A = length × width

A = xy

Here, A = 2500 m²

so, 2500 = xy

⇒ y = 2500/x

Using the formula for the perimeter of the rectangle, the perimeter of the garden would be,

P = 2x + 2y

But  a rectangular garden is partitioned into 4 parts by constructing three additional fences parallel to one of the side.

So, the perimeter would be,

P = 2x + 5y

sides, in addition to fencing the perimeter.

P = 2x + 5(2500/x)

P = 2x + (12500/x)

Consider the derivative of P(x) with respect to x.

P'(x) = 2 - 12500/x²

To find the minimum value consider P'(x) = 0

2 - 12500/x² = 0

2 = 12500/x²

x² = 12500/2

x² = 6250

x = 79.05 m

and y =  2500/79.05

y = 31.63 m

So, the minimum amount of fencing would be,

P = 2x + 5y

P = 2(79.05) + 5( 31.63 )

P = 316.25 meters

P ≈ 317 meters

The probability that Claire spinning an 8 is around 0.078, or 7.8%.

We may use the strategy of calculating favorable results over total outcomes to get the likelihood that Claire spins a sum of 8. We must specifically determine how many possibilities there are to reach a sum of 8 when spinning the two spinners and divide that number by the total number of possible outcomes.

To illustrate, we can use a table to display all of the possible results for spinning two spinners labeled 1-8, and then compute the sum of each outcome:

There are 64 possible outcomes (8 spinners 1 choice times 8 spinner 2 choices), and we can see that there are 5 methods to reach a sum of 8: (2,6), (3,5), (4,4), (5,3), and (6,2). As a result, the likelihood of getting an 8 is:

P(sum of 8) = number of favorable outcomes / total number of outcomes

            = 5 / 64

            = 0.078125

So the likelihood of Claire spinning an 8 is around 0.078, or 7.8%.

Answer:

A. 2

Step-by-step explanation:

Let's interpret the function.

First, let's look at the top section:

[tex]f(x)=x+2[/tex] if [tex]x < 1[/tex]

So, if the value of x is less than 1, to find f(x), we should add 2 to x.

Let's check if x is less than 1:

[tex]x=3\\x < 1\\3 < 1[/tex]

3 is not less than one, so to find f(x), we cannot add 2 to x.

The second part of the function is:

[tex]f(x)=x-1[/tex] if [tex]x\geq 1[/tex]

So, if the value of x is greater than or equal to 1, to find f(x), we should subtract 1 from x.

Let's check if x is greater than or equal to 1:

[tex]x=3\\x\geq 1=\\3\geq 1[/tex]

3 is greater than or equal to 1, so to find f(x), we should use x-1.

[tex]x-1=\\3-1=\\2[/tex]

Thus, f(3) = 2; the answer is A.

Answer:

-8.5 and 7.5

Step-by-step explanation:

Let's call the two numbers x and y. We know that their difference is 16, so we can write:

x - y = 16 or x = y + 16

We want to find the values of x and y that minimize the expression:

x + y + xy

Substituting x = y + 16, we get:

(y + 16) + y + (y + 16)y

Simplifying and expanding, we get:

y^2 + 17y + 16

To minimize this expression, we can take its derivative with respect to y and set it equal to 0:

d/dy (y^2 + 17y + 16) = 2y + 17 = 0

Solving for y, we get:

y = -8.5

Substituting y = -8.5 into x = y + 16, we get:

x = 7.5

Therefore, the two numbers with a difference of 16 such that the result of adding their sum and their product is a minimum are -8.5 and 7.5.

The highest point of a normal curve, also known as a Gaussian distribution or bell curve, always occurs at the mean. This is because the normal curve is symmetrical around the mean, with the same number of values on either side of the mean. Therefore, the peak of the curve must be directly above the mean.

The standard deviation is a measure of how spread out the values in a distribution are. For a normal distribution, approximately 68% of the values fall within one standard deviation of the mean, 95% fall within two standard deviations of the mean, and 99.7% fall within three standard deviations of the mean. Therefore, while the highest point of the normal curve occurs at the mean, the curve does extend out to both sides of the mean, with the height of the curve gradually decreasing as the distance from the mean increases.

Specifically, the point at which the curve begins to flatten out on either side of the peak is approximately one standard deviation away from the mean. At two standard deviations away from the mean, the curve has flattened out significantly, and at three standard deviations away from the mean, the curve is almost entirely flat. This is known as the empirical rule, or the 68-95-99.7 rule.

Understanding the normal curve and its characteristics is important in statistics and data analysis, as many real-world phenomena can be approximated using a normal distribution. By knowing the mean and standard deviation of a distribution, we can make predictions about the likelihood of various outcomes occurring.

There are 6 mL,and if each mL is 0.2tsp, then you have to multiply.

The Results:

a) The measure of ∠BDC = 67°

b) The measure of arc DAC = 46°

a) The measure of ∠BDC

Since DC ⊥ AB, ∠DCB is a right angle, which means it measures 90°. Also, given that m∠DCB = 23, we can use the fact that the angles in a triangle sum to 180° to find ∠DBC.

∠DBC + ∠DCB + ∠B = 180 (angles in a triangle sum to 180)

∠DBC + 90 + 23 = 180 (substituting values)

∠DBC = 180 - 90 - 23 = 67°.

Thus, the measure of ∠BDC = 67°

b) The measure of arc DAC:

Since AB = AC, it implies that ∠ABC = ∠ACB (angles opposite to equal sides of an isosceles triangle are equal). Therefore, ∠ACB is also 23°.

Now, since ∠ACB is an inscribed angle that intercepts the arc DAC, the measure of the arc DAC is twice the measure of ∠ACB.

Arc DAC = 2 × ∠ACB = 2 × 23 = 46°.

Therefore, the measure of arc DAC is 46°.

We can predict that out of 200 repetitions of the experiment, approximately 75 of them will result in exactly 2 of the 3 flips landing on tails.

Probability is a branch of mathematics that deals with the study of random events and the likelihood of their occurrence. It is used to quantify the uncertainty associated with a particular event or outcome. In simpler terms, probability is a measure of the likelihood that a certain event will occur, expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain.

There are different types of probability, including classical probability, empirical probability, and subjective probability. Classical probability is based on the assumption of equally likely outcomes, while empirical probability is based on actual observations or experiments. Subjective probability, on the other hand, is based on personal judgment or belief.

The probability of getting tails on any single flip of a fair coin is 1/2. Since we are flipping the coin three times, the probability of getting exactly two tails is given by the binomial probability formula:

P(exactly 2 tails) = (number of ways to get 2 tails out of 3) * (probability of getting tails)² * (probability of getting heads)¹

The number of ways to get 2 tails out of 3 is given by the binomial coefficient "3 choose 2", which is 3. So we have:

P(exactly 2 tails) = 3 * (1/2)² * (1/2)¹ = 3/8

This means that the probability of getting exactly 2 tails in one trial of flipping the coin 3 times is 3/8.

To predict the number of repetitions out of 200 that will result in exactly 2 tails, we can multiply the probability of getting exactly 2 tails in one trial by the total number of trials:

Number of repetitions with exactly 2 tails = P(exactly 2 tails) * total number of trials

Number of repetitions with exactly 2 tails = (3/8) * 200

Number of repetitions with exactly 2 tails = 75

Therefore, we can predict that out of 200 repetitions of the experiment, approximately 75 of them will result in exactly 2 of the 3 flips landing on tails.
