This is a inequality problem.

After answering the presented question, we can conclude that Option B inequality may be the best option if the cost per doughnut is less than $4.94, despite having fewer donuts per box than Option C.

In mathematics, an inequality is a non-equal connection between two expressions or values. As a result, imbalance leads to inequity. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two values are not equal, the not equal symbol is typically used (). Various disparities, no matter how little or huge, are utilised to contrast values. Many simple inequalities can be solved by altering the two sides until just the variables remain. Yet, a lot of factors contribute to inequality: Negative values are divided or added on both sides. Exchange left and right.

To do so, we split the price of each box by the number of donuts inside:

Option A: Donut cost = 31.60 / 2 = 15.80

Option B: Donut cost = Unknown / 4 = Unknown

Option C: Donut cost = 39.50 / 8 = 4.94

Option C, with a cost per doughnut of only $4.94, delivers the best value based on this computation. Unfortunately, we can't tell if this is the greatest alternative until we know how much Option B costs.

Option B may be the best option if the cost per doughnut is less than $4.94, despite having fewer donuts per box than Option C.

( To find the lowest common multiple of any number you should find the prime factorization of 418)

(Attached)

418 = 2 × 11 × 19

The distance between the points (4, 5) and (2, 2) is approximately 3.61 units.

What is the distance?

To find the distance between two points, we can use the distance formula:

distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

Using the given points (4, 5) and (2, 2), we have:

distance = √[(2 - 4)² + (2 - 5)²]

= √[(-2)² + (-3)²]

= √[4 + 9]

= √13

So the distance between the points (4, 5) and (2, 2) is approximately 3.61 units.

To graph these points, we would plot them on a coordinate plane. The point (4, 5) would be two units to the right of the y-axis and five units up from the x-axis.

The point (2, 2) would be two units to the right of the y-axis and two units up from the x-axis. We could then use a ruler to measure the distance between the two points on the graph to verify that it is approximately 3.61 units.

Answer:

To prove that ∆ABC=8 ∆EFG, we need to use the concept of similarity of triangles and the ratio of their corresponding sides.

Given that ∆ABC and ∆EFG are similar triangles, we can write:

AB/EF = BC/FG = AC/EG = k (a constant)

Let's assume that AB = x, BC = y, and AC = z. Similarly, let EF = p, FG = q, and EG = r.

From the given information, we can write:

EF = AB/2 (since E is the midpoint of AB)

FG = BC/2 (since F is the midpoint of BC)

EG = AC/2 (since G is the midpoint of AC)

Substituting these values in the above equation, we get:

x/p = y/q = z/r = k

Now, let's consider the area of the triangles.

Area of ∆ABC = (1/2) * AB * BC * sin(∠BAC)

Area of ∆EFG = (1/2) * EF * FG * sin(∠EFG)

Using the values we have assumed earlier, we get:

Area of ∆ABC = (1/2) * x * y * sin(∠BAC)

Area of ∆EFG = (1/2) * (x/2) * (y/2) * sin(∠EFG)

Simplifying these expressions, we get:

Area of ∆ABC = (xy/2) * sin(∠BAC)

Area of ∆EFG = (xy/8) * sin(∠EFG)

Now, since the triangles are similar, their corresponding angles are equal. Therefore,

sin(∠BAC) / sin(∠EFG) = z/r

Substituting the value of k from earlier, we get:

sin(∠BAC) / sin(∠EFG) = 2k

Solving for sin(∠EFG), we get:

sin(∠EFG) = sin(∠BAC) / (2k)

Substituting this value in the expression for the area of ∆EFG, we get:

Area of ∆EFG = (xy/8) * (sin(∠BAC) / (2k))

Area of ∆EFG = (xy/16) * sin(∠BAC)

Now, substituting the value of the area of ∆ABC in this expression, we get:

Area of ∆EFG = (1/2) * Area of ∆ABC * (1/8)

Area of ∆EFG = (1/16) * Area of ∆ABC

Therefore, we have proved that ∆ABC=8 ∆EFG.

According to the given information the missing measurement is the longer length or base of the parallelogram, which measures 10 meters.

A parallelogram is a four-sided geometric shape with two pairs of parallel sides. The opposite sides of a parallelogram have equal lengths and are parallel to each other. The opposite angles of a parallelogram are also equal.

Based on the clues provided, we can determine that the missing measurement is the longer length of the shape. Here's how we can calculate it:

Clue #1 tells us that the shape has four sides, with one set being parallel. This means that the shape is a parallelogram.

Clue #2 tells us that the area of the parallelogram is 40 square meters.

Clue #3 tells us that the height of the parallelogram is 4 meters.

Clue #4 tells us that one of the lengths of the parallelogram is 6 meters.

To find the missing measurement, we can use the formula for the area of a parallelogram:

Area = base x height

Since we know the area and height, we can plug those values in:

40 = base x 4

Solving for the base, we get:

base = 40 / 4 = 10

So the missing measurement is the longer length or base of the parallelogram, which measures 10 meters.

All possible values of v are integers greater than or equal to 28.

In a connected planar graph with 26 faces, the number of edges can be found using Euler's formula, which states that v - e + f = 2 for any connected planar graph. Since the graph is connected and planar, we know that e = 3v/2 - 3 (using the handshaking lemma and Euler's formula), and substituting this into Euler's formula gives:

v - (3v/2 - 3) + 26 = 2

Simplifying this equation yields v = 52 - 2f.

Since all vertices have the same degree, each face must have degree at least 3, and the sum of the degrees of the faces is equal to 2 times the number of edges. Therefore, we have:

3f ≤ 2e = 3v - 6

f ≤ (3v - 6)/3 = v - 2

Combining this with the fact that there are 26 faces, we get:

what is bayes theorem ?

Let’s use Bayes’ theorem to solve this problem. Let A be the event that it rains in Spain and B be the event that hurricanes happen in Hartford. We want to find P(A|B). We know that P(B|A) = 0.08 and P(B|A’) = 0.03 where A’ is the complement of A (i.e., it does not rain in Spain). We also know that P(A) = 1/13 and P(A’) = 12/13.

Bayes’ theorem states that:

P(A|B) = P(B|A) * P(A) / [P(B|A) * P(A) + P(B|A’) * P(A’)]

Substituting the values we have:

P(A|B) = (0.08 * 1/13) / [(0.08 * 1/13) + (0.03 * 12/13)] = 0.2192 (rounded to four decimal places)

So, the probability of picking a 4 and then picking an even number is 15/28.

To find probability, you need to follow these steps:

Identify the total number of possible outcomes of an event. Let's call this number "n."

Identify the number of favorable outcomes, which are the outcomes that you're interested in. Let's call this number "f."

Calculate the probability of the event as the ratio of the number of favorable outcomes to the total number of outcomes:

Probability = f / n

For example, if you're flipping a fair coin, there are two possible outcomes: heads or tails. The total number of outcomes is 2, and the number of favorable outcomes is 1 (either heads or tails). Therefore, the probability of getting heads is:

Probability of heads = 1 / 2 = 0.5.

The weight of a puppy modeled by the equation 2x - y = 2 is represented by graph H.

The graph's intersection with the y-axis is known as the y-intercept. Finding the intercepts for any function with the formula y = f(x) is crucial when graphing the function. An intercept can be one of two different forms for a function. The x-intercept and the y-intercept are what they are. A function's intercept is the location on the axis where the function's graph crosses it.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. whereas there is a net change in the x coordinate, the y coordinate changes just little.

Given the modeled equation for puppy's growth is 2x - y = -2.

The standard equation of line is y = mx + c.

Converting the given model in standard form we have:

2x - y = -2

-y = - 2x - 2

y = 2x + 2

From the equation we see that the y-intercept is 2 and slope is 2.

The graph that has the y-intercept at 2 and slope of 2 is graph H.

  this represents  a     Z -score of -1    

From Z-score table this represents .1587 of the sample or 15.87 %

The percentage of all scores that occur at 30 or below in a distribution with a mean of 25 and a standard deviation of 5 is 84.13%.

To find the percentage of all scores that occur at 30 or below, we need to calculate the z-score first. The z-score formula is (x - μ) / σ, where x is the score of interest, μ is the mean, and σ is the standard deviation.

So, for x = 30, μ = 25, and σ = 5, the z-score is calculated as (30 - 25) / 5 = 1.

We can then use a standard normal distribution table or a calculator to find the proportion of the area under the curve to the left of z = 1. This gives us the percentage of all scores that occur at 30 or below.

Using a standard normal distribution table, we find that the proportion of the area under the curve to the left of z = 1 is 0.8413.

The perimeter of the rectangle is 8x + 14.

To find the perimeter of a rectangle with an area of 3x^2 + 17x + 10, we need to use the formula for the area of a rectangle, which is A = lw, where A is the area, l is the length, and w is the width. In this case, we have:

A = lw = 3x^2 + 17x + 10

We can factor this quadratic expression to get:

A = (3x + 2)(x + 5)

Since the length and width of the rectangle are both positive numbers, we know that the factors (3x + 2) and (x + 5) must both be positive. This means that x > -5/3 and x > -5.

To find the perimeter of the rectangle, we need to add up the lengths of all four sides. Since the opposite sides of a rectangle are equal in length, we can use the factored form of the area to find the length and width of the rectangle:

l = 3x + 2

3 and 3/5 = (5 * 3 + 3) / 5 = 18/5

2 and 1/4 = (4 * 2 + 1) / 4 = 9/4

Now we can multiply the two fractions:

Where:

n is the sample size

z is the z-score corresponding to the desired level of confidence (95% confidence level corresponds to a z-score of 1.96)

p is the estimated population proportion (since we have no reasonable estimate, we use 0.5, which gives the largest possible sample size)

E is the desired margin of error (0.05)

Plugging in the values, we get:

[tex]n = \frac {(1.96^2 * 0.5 * (1-0.5))} { 0.05^2 }= 384.16[/tex]

Since we cannot have a fractional sample size, we round up to the nearest whole number to get a minimum sample size of 385.
