Answer:

250°

Step-by-step explanation:

We know that a circle has a total of 360°.

Now we know that ∠ROW is 110° and that Arc RAW has the same End points as ∠ROW.

We can safely assume that arc RAW will be the difference of ∠ROW and 360°.

So we then get:

360° - 110° = 250°

This means that Arc RAW will be 250°

Victoria's daughter's cookies will have more butter. Victoria uses 0.68g of butter per gram of flour, whereas her daughter uses 0.85g of butter per gram of flour.

Answer:

Daughter is using 0.17 gram more butter for each gram flour.

Step-by-step explanation:

Victoria's favorite cookie recipe uses 170 grams of butter for every 250 grams of flour  = [tex]\frac{170}{250}[/tex]  = 0.68

Therefore, this recipe needs 0.68 grams of butter for every gram flour.

Her daughter made cookies using 340 grams of butter for every 400 grams of flour = [tex]\frac{340}{400}[/tex] = 0.85

She is using 0.85 grams of butter for every gram flour.

Victoria's daughter is using 0.17 gram of butter more on every gram flour.

Answer:

  674.2 lb

Step-by-step explanation:

(5 ft)·(8 ft)·(1.2 in)·(12 in/ft)²·(2.54 cm/in)³·(2.7 g/cm³)/(453.592 g/lb) ≈ 674.2 lb

_____

Comment on units conversion

Units conversion is easily done using conversion factors that have a value of 1. That is, the value of the numerator is equal to the value of the denominator. (12 in = 1 ft, for example). The numerator units are chosen to match units you want, while the denominator units are chosen to match units you want to cancel.

Here, we convert in³ to cm³ to lb using conversion factors given and ones we know.

Answer:

63%

Step-by-step explanation:

This is a problem of conditional probability.

The two events that are given are:

We have to find the probability of being stuck in the snow AND requiring a tow truck which can be given as P(S and T)

We are also given the conditional probability, which is P(T | S) = 90% = 0.90

Using the given formula for our case we can modify the formula as:

[tex]P(T|S)=\frac{P(S \cap T)}{P(S)}[/tex]

[tex]0.90=\frac{P(S \cap T)}{0.70}\\\\ P(S \cap T)=0.90 \times 0.70\\\\ P(S \cap T)=0.63[/tex]

Therefore, there is 63% (0.63) chance that you will get stuck in the snow with your car AND require a tow truck to pull you out

The probability of getting stuck in the snow and requiring a tow truck is found by multiplying the individual probabilities, resulting in a 63% chance.

The question asks for the probability that you will get stuck in the snow with your car AND require a tow truck to pull you out. To calculate this combined probability (P(A AND B)), we use the rule of multiplication for dependent events, which states P(A AND B) =[tex]P(B|A) imes P(A).[/tex] Here, P(A) is the probability of getting stuck in the snow, and P(B|A) is the probability of requiring a tow truck given that you are stuck.

In numbers, this becomes P(A AND B) = [tex]0.90 imes 0.70 = 0.63 or 63%[/tex]. Therefore, the chance that you will get stuck in the snow and require a tow truck to pull you out is 63%.

To answer the question, a statistical hypothesis test comparing the proportions of successful repair attempts is needed. This involves calculating a Z-score and referencing Z-tables or statistical software for the p-value. Also, a one-sided 95% confidence interval needs to be calculated for the proportion differences using the Z-test.

To answer this question, we need to perform a statistical hypothesis test which involves the comparison of proportions. Let's denote p1 as the proportion of successful repairs for tears greater than 25 mm (15 successful out of 19 trials), and let p2 for tears shorter (21 successful out of 29 trials).

To find the p-value, we need to implement a Z-test using the formula Z = (p1 - p2) - 0 / sqr((p(1-p)(1/n1 + 1/n2)) where p = (x1 + x2) / (n1 + n2). By substituting the values in the formula we get our z-score, which is used to find the p-value from the Z-tables or by using statistical software.

As for the 95% confidence interval, we will also use the Z-test formula, but this time the Z-value for the 95% one-sided confidence level which is approximately 1.645. Substituting the values in we can calculate our confidence bound. Please remember that to make accurate calculations you need to use calculated Z-score and confidence interval in the Z distribution method.

The perimeter of the yin is bigger than the circumference of the full yin and yang symbol. This is due to the fact that the yin and yang symbol is made up of two semicircles which extend beyond the boundaries of the separate yin and yang halves.

The Yin and Yang symbol is a Chinese symbol that represents complementary characteristics found in all things, such as light and dark, hot and cold, good and evil, and so on. A circle is divided into two sections, one black and one white, containing a smaller circle of the opposing color in each section.

Yin is represented by the black portion, which is connected with feminine traits, passivity, darkness, or coldness. Yang is represented by the white part, which is connected with masculine attributes such as activity, brightness, and warmth. The symbol is intended to reflect the harmony and balance of both of these opposing energies.

Therefore, the perimeter of the yin is bigger than the circumference of the full yin and yang symbol.

Final answer:

The circumference of the entire yin and yang symbol is greater than the perimeter of the yin semicircle, as the full symbol represents a complete circle while the semicircle includes only half the circumference plus its diameter.

Explanation:

The question about the Chinese symbol for yin and yang essentially asks about the relationship between the circumferences of two geometric shapes. If we consider the yin and yang symbol as a whole to be a circle, and the yang (or yin, since they are symmetrical) as a semicircle, then we can infer the following regarding circumferences and perimeters:

The circumference of a circle is 2πr, where r is the radius of the circle. The perimeter of a semicircle (half of the full circle and including the diameter) is πr + 2r. If we take the full yin and yang symbol to have a circumference of 2πr (since the full symbol is also circular), then the perimeter of the yang semicircle (which includes the straight edge boundary of the yin) would be less than the circumference of the full symbol, as it lacks the other semicircle's curved edge. In mathematical terms, πr + 2r is less than 2πr for any positive value of r.

Answer:

Option A.

Step-by-step explanation:

It is given secθ = - [tex]\frac{4}{3}[/tex]

then cosθ = -[tex]\frac{3}{4}[/tex]

Now we know the identity

sinθ = [tex]\sqrt{1-cos^{2}\theta }[/tex]

       = [tex]\sqrt{1-(-\frac{3}{4} )^{2}}[/tex]

       = [tex]\frac{\sqrt{7} }{4}[/tex]

Now sin2θ = 2sinθcosθ

Now we put the values of cosine and sine in the formula

sin2θ = 2×(-[tex]\frac{3}{4}[/tex])([tex]\frac{\sqrt{7}}{4}[/tex])

         = -[tex]\frac{3\sqrt{7}}{8}[/tex]

Answer:

101 degrees

Step-by-step explanation:

- A circle with two chords

- The two cords have common start point A on the circle

- The chord AB subtended arc AB with measure 115°

- The chord AC subtended arc AC with measure 43°

- The measure of any circle is 360°

* These two cords divide the circumference of the circle into

 three arcs, arc AB , arc AC and arc BC

∵ The measure of arc AB = 115°

∵ The measure of arc AC = 43°

∵ The measure of the circle is 360°

∴ The measure of arc BC = 360 - (115 + 43) = 360 - 158 = 202°

- In the circle, the angle whose vertex is on the circle is

called inscribed angle and subtended by the opposite arc,

its measure is half the measure of the subtended arc

∵ ∠BAC is an inscribed angle subtended by arc BC

∴ m∠BAC = 1/2 measure of arc BC

∵ The measure of arc BC = 202°

∴ m∠BAC = 202 ÷ 2 = 101°

Answer:   105°

Step-by-step explanation:

∠U and ∠S are supplementary angles, so

∠U + ∠S = 180°

 x  +  75° = 180°

 x            = 105°

Answer:

x = 105 degrees.

Step-by-step explanation:

RS is parallel to  TU so x + 75 = 180

x = 105 degrees.

As its is isosceles y is also = 105 degrees.
