Answer: Let's start by representing the number of Blu-Ray discs sold as x.

According to the problem, the store sold 2/3 as many DVDs as Blu-Ray discs. So the number of DVDs sold is 2/3 of x, or (2/3)x.

We also know that the total number of DVDs and Blu-Ray discs sold was 280. So we can set up an equation:

(2/3)x + x = 280

To solve for x, we can simplify the equation by combining like terms:

(5/3)x = 280

Multiplying both sides by 3/5, we get:

x = 168

So the number of Blu-Ray discs sold was 168.

To find the number of DVDs sold, we can use the expression we derived earlier:

(2/3)x = (2/3) * 168 = 112

Therefore, the store sold 112 DVDs on that day.

Step-by-step explanation:

The value of h is 1.89. The solution involves setting up and solving an equation involving the probabilities of selecting a red or white present.

Santa Claus has a total of 3h+11 red presents and h+5 white presents in his stocking. If Ethan selects a present at random from the stocking, the probability of obtaining a red present is given as 19/26. Using this information, we can form an equation (3h+11)/(4h+16) = 19/26 and solve for h. Cross-multiplying and simplifying, we get 494h = 936, which leads to h = 1.89. Therefore, the value of h that satisfies the given conditions is approximately 1.89.

Answer:

116

Step-by-step explanation:

We can see that the two lines in between the triangle are the same size. This must mean that if we were to move the inner triangle and line it up to the triangle on the edge it must be the same size. We are also told that one of the angles on the side is 116. This means that the value of x must also be 116!

In general, you would need to know the number of polygons in the original shape and the rule for how the shape is expanded or repeated in each iteration to calculate the number of polygons in a fractal expansion.

A fractal is a geometric shape that has intricate detail at arbitrarily small scales and typically has fractal dimensions that rigorously surpass topological dimensions. Several fractals resemble one another at different scales, as shown in the Mandelbrot set's sequential magnifications. Self-similarity, also known as expanding symmetry or unfolding symmetry, is the display of similar patterns at progressively smaller scales; if this replication is precisely the same at every scale, as in the Menger sponge, the shape is referred to as affine self-similar. The academic field of measure theory includes fractal geometry.

Depending on the particular kind of fractal under consideration, a polygon's fractal expansion can be calculated using a specific algorithm. However, the formula will typically entail iteratively transforming the original polygon with geometric operations.

For instance, by continually removing the central triangle from a larger equilateral triangle, the Sierpinski triangle—a well-known fractal—can be created. The remaining triangle is divided into three smaller replicas, which are then put together to make an equilateral triangle at the end of each iteration. The formula below can be used to determine the amount of triangles in each iteration:

the number of triangles in the nth repetition is represented by

Another illustration is the Koch snowflake, which is created by repeatedly dividing each of an equilateral triangle's three sides into two segments and swapping out the middle segment for two segments that also make an equilateral triangle. The following algorithm can be used to determine how many line segments are used in each iteration:

the number of line segments in the nth cycle is represented by L(n).

Generally speaking, the expansion formula for a fractal will rely on the particular rule or algorithm that was used to create the fractal.

Answer:

If 400 ml of squash is made by mixing 50 ml of cordial with water, then the remaining volume is water.

The volume of water used in making the squash = 400 ml - 50 ml = 350 ml

The fraction of the drink that is water is:

Water volume / Total volume = 350 ml / 400 ml = 7/8

Therefore, 7/8 of the drink is water.

Answer:

[tex]\frac{7}{8}[/tex]

Step-by-step explanation:

We know that 400ml squash = 50ml of Cordial With Water.

Therefore in 400ml of squash, amount of water will be 400ml - 50ml = 350ml of water.

In fraction form, this will be [tex]\frac{350}{400} =\frac{7}{8}[/tex]

Step-by-step explanation:

To rewrite (24 + 40) as an integer times the sum of two integers, Gracie first factored out 2, obtaining:

(24 + 40) = 2 × (12 + 20)

We can check that this is true by distributing the 2:

2 × (12 + 20) = 2 × 12 + 2 × 20 = 24 + 40

Now, Gracie is looking for other numbers greater than 2 that she can factor out of (24 + 40) to rewrite the expression as an integer times the sum of two integers.

One way to approach this is to look for other common factors between 24 and 40. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors of 24 and 40 are 1, 2, 4, 8, and the largest factor is 8.

Therefore, Gracie can factor out 4 or 8 to rewrite the expression as an integer times the sum of two integers. For example:

(24 + 40) = 4 × (6 + 10)

(24 + 40) = 8 × (3 + 5)

Note that we can also factor out 1 or 2, but that would not change the expression in any meaningful way.

The 95% of the babies born to 22-year-old mothers will weigh between 3308.4 grams and 5665.6 grams.The correct answer is option C) (3051.25, 5408.49).

To get started, let's put the mother's age into the given equation to determine the mean birth weight. Then, we'll use the RMS value to calculate the standard deviation.The equation for predicting baby birth weight in grams given the mother's age is: Y = -1163.45 + 245.15XWhere X is the mother's age, and Y is the baby's birth weight. We are given X=22, so let's use that to find the predicted mean birth weight:Y = -1163.45 + 245.15(22) = 4486.95 gramsThe RMS is given to be 589.3 grams. Because we're told that the distribution is approximately normal, we can use the 68-95-99.7 rule to find the 95% prediction interval. Here are the steps:Subtract the RMS from the mean to find the lower endpoint of the interval:4486.95 - (2 x 589.3) = 3308.35Add the RMS to the mean to find the upper endpoint of the interval:4486.95 + (2 x 589.3) = 5665.55Round both values to four decimal places, as instructed in the problem:3308.35 rounds to 3308.4 grams5665.55 rounds to 5665.6 gramsTherefore, about 95% of the babies born to 22-year-old mothers will weigh between 3308.4 grams and 5665.6 grams.The correct answer is option C) (3051.25, 5408.49).

Answer:

The reduced answer is 1/4

Answer:

5 and 13

Step-by-step explanation:

given the first number is x and the second number is y

then x + y = 18 => y = 18 - x

also

x^2 + y^2 = 194

substitute

x^2 + (18 - x)^2 = 194

x^2 + x^2 - 36x + 324 = 194

2x^2 - 36x + 130 = 0

2(x^2 - 18x + 65) = 0

x^2 - 18x + 65 = 0/2

x^2 - 13x - 5x + 65 = 0

x(x - 13) - 5(x - 13) = 0

(x - 13)(x - 5) = 0

=> x - 13 = 0 => x = 13

=> x - 5 = 0 => x = 5

if x = 13, y = 18 - 13 = 5

if x = 5, y = 18 - 5 = 13

so x and y can be either 5 and 13

4*sqrt(2)

Step-by-step explanation:

To find the distance between two points, we use the distance formula, which is the following:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

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

Plugging in the values for the given points, we get the following:

d = sqrt((1 - (-3))^2 + (-2 - (-6))^2)

= sqrt((1 + 3)^2 + (-2 + 6)^2)

= sqrt(4^2 + 4^2)

= sqrt(32)

= 4*sqrt(2)

Therefore, the distance between the points (-3, -6) and (1, -2) is 4*sqrt(2).

The probability of Jones being the author is 0.0275.

The new evidence updates the probability of Jones being the author from 1 in 4 to 0.0084. The probability of Smith being the author is 0.4.

P(Jones|that) = P(that|Jones) x P(Jones) / (P(that|Jones) x P(Jones) + P(that|Smith) x P(Smith))

P(Jones|that) = 0.0084 x 0.25 / (0.0084 x 0.25 + 0.4 x 0.75)

P(Jones|that) = 0.0084 / (0.0084 + 0.3)
