The decompositions are:

146 = 73*2

92 = 2*2*23

To do it, just grab one of the numbers and keep dividing it by prime numbers (the smallers first, these are the factors) until you reach 1.

For example.

92

We start with 2.

92/2 = 46

We keep dividing by 2 until we can't do it, so let's try again:

46/2 = 23

And 23 is prime, so:

23/23 = 1

Then the decomposition is.

92 = 2*2*23

Now the other:

146/2 = 73

And 73 is prime, so the decomposition is:

146 = 73*2

Answer:

0.2

Step-by-step explanation:

C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.

So to find that you would divide y by x.

In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.

Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

To create a histogram, the scientist needs to group the data into categories or bins. The number of bins and the size of each bin can affect the shape of the resulting histogram, so the scientist needs to choose these values carefully.

One common method for determining the number of bins is to use the square root rule, which states that the number of bins should be approximately equal to the square root of the sample size. In this case, the sample size is 15, so the square root rule suggests using around 4-5 bins.

To determine the size of each bin, the scientist can consider the range of the data. The minimum value is 1.1 and the maximum value is 2.45, so the range is 2.45 - 1.1 = 1.35. The size of each bin should be small enough to capture the variation in the data, but not so small that there are too few observations in each bin.

One possible way to group the data into 4 bins with a bin size of 0.3 would be:

1.1 - 1.4

1.4 - 1.7

1.7 - 2.0

2.0 - 2.3

The last observation (2.45) would fall in the bin "2.3-2.6" which is not included in the bins, but can be included in the last bin.

This grouping allows the scientist to see the frequency of growth measurements falling within each bin. The height of each bar in the histogram will represent the frequency of observations in that bin.

The statement "P implies Q" is false under the following conditions: a) P is true and Q is false, and d) P is false and Q is true.

The statement "P implies Q" can be expressed as "if P, then Q." It is a conditional statement where P is the antecedent (the condition) and Q is the consequent (the result).

To determine when the statement is false, we need to identify cases where P is true but Q is false, or when P is false but Q is true.

Option a) states that both P and Q are true. In this case, the statement "P implies Q" holds true because if P is true, then Q is true.

Option b) states that both P and Q are false. In this case, the statement "P implies Q" is considered true because the antecedent (P) is false.

Option c) states that P is true and Q is false. Under this condition, the statement "P implies Q" is false because when P is true, but Q is false, the implication does not hold.

Option d) states that P is false and Q is true. In this case, the statement "P implies Q" is true because the antecedent (P) is false.

Therefore, the conditions under which the statement "P implies Q" is false are a) P is true and Q is false, and d) P is false and Q is true.

To calculate the gain on the sale of the office furniture, we need to determine the asset's book value and compare it to the sale price.

First, let's calculate the accumulated depreciation on the furniture. The furniture was purchased on January 1, 2014, and the straight-line depreciation method is used over 10 years with a salvage value of $80,200.

Depreciation per year = (Cost - Salvage Value) / Useful Life

Depreciation per year = ($746,800 - $80,200) / 10 years

Depreciation per year = $66,160

Next, we need to calculate the accumulated depreciation for the period from January 1, 2014, to May 1, 2021 (the date of the sale). This is approximately 7.33 years.

Accumulated Depreciation = Depreciation per year × Years

Accumulated Depreciation = $66,160 × 7.33 years

Accumulated Depreciation = $484,444.80

Now, we can calculate the book value of the furniture:

Book Value = Cost - Accumulated Depreciation

Book Value = $746,800 - $484,444.80

Book Value = $262,355.20

Finally, we can calculate the gain on the sale:

Gain on Sale = Sale Price - Book Value

Gain on Sale = $300,000 - $262,355.20

Gain on Sale = $37,644.80

Therefore, the gain that should be recognized on the sale of the office furniture is approximately $37,644.80.

The gain that should be recognized on the sale of the office furniture is $84,080.

The gain is calculated by subtracting the equipment's book value from the sale price. This gain will be reported on the company's income statement. Here is how to calculate the gain:First, find the equipment's book value using the straight-line method of depreciation.

Straight-line depreciation is calculated by taking the difference between the equipment's original cost and its salvage value, and then dividing it by the number of years the equipment is used. The annual depreciation expense is then multiplied by the number of years the equipment is used to find the equipment's book value at the end of its useful life.

For this question, the book value of the equipment at the time of sale is:Cost of equipment: $746,800Salvage value: $80,200Depreciable cost: $746,800 - $80,200 = $666,600Annual depreciation: $666,600 ÷ 10 years = $66,660Book value at the end of 2020: $666,600 - ($66,660 x 7) = $156,420

Next, subtract the equipment's book value from the sale price to find the gain:Sale price: $300,000Book value: $156,420Gain: $143,580Finally, round the gain to the nearest dollar:$143,580 ≈ $143,580.00So the gain that should be recognized on the sale of the office furniture is $84,080.

The thief originally stole 64 plants.

In mathematics, it deals with numbers of operations according to the statements.

Here,
Let the number of plants originally stolen by the thief be x.
On the way​ out, the thief meets three security​ guards, one after another. To each security​ guard, the thief is forced to give one-half of the plants that he still​ had, plus 2 more.​

Here,
For gourd 1 the planet is given = 1/2 x
For gourd 2 the planet is given = 1/2 * 1/2 x = 1/4 x
For gourd 3 the planet is given = 1/2*1/4 x = 1/8 x
Total plant given to the gourds = 1/2x +1/4x +1/8x + 2 = 7/x/8x +2
Finally, the thief leaves the nursery with 10 plants
x - 7x/8 + 2 = 10
x/8 = 8
x = 64

The diameter of the circle is approximately 60 inches.

To explain further, we can use the formula relating the central angle of a sector to the length of its intercepted arc. The formula states that the length of the intercepted arc (A) is equal to the radius (r) multiplied by the central angle (θ) in radians.

In this case, we are given the central angle (225 degrees) and the length of the intercepted arc (30π inches).

To find the diameter (d) of the circle, we need to find the radius (r) first. Since the length of the intercepted arc is equal to the radius multiplied by the central angle, we can set up the equation 30π = r * (225π/180). Simplifying this equation gives us r = 20 inches.

The diameter of the circle is twice the radius, so the diameter is equal to 2 * 20 inches, which is 40 inches. Therefore, the diameter of the circle is approximately 60 inches.

In summary, by using the formula for the relationship between central angle and intercepted arc length, we can determine the radius of the circle. Doubling the radius gives us the diameter, which is approximately 60 inches.

a. To determine if there are any arbitrage opportunities in the market, we need to check if the payoff matrix A is linearly dependent on the price vector S.

If A and S are linearly dependent, then there are no arbitrage opportunities. If they are linearly independent, we can construct an arbitrage portfolio.

In this case, we observe that the rank of the matrix A is 2, which is less than the number of columns (3). Therefore, A and S are linearly dependent, indicating that there are no arbitrage opportunities in this market.

b. To find the no-arbitrage price of the security with payoff b, we need to determine the weights of the basis assets that replicate the payoff vector b. We can do this by solving the equation A * x = b, where A is the payoff matrix and x is the vector of weights.

The equation, we get the following system of equations:

x₁ + x₃ = 5

3x₁ + 2x₂ + x₃ = 4

Solving this system of equations, we find x₁ = 2, x₂ = -1, and x₃ = 3.

Therefore, the no-arbitrage price of the security with payoff b is given by the dot product of the weights and the price vector S:

No-arbitrage price = (2 * 1) + (-1 * 2) + (3 * 1.5) = 3 + (-2) + 4.5 = 5.5

Answer:

HT = 17 cm

<T = 58°

<H = 32°

Step-by-step explanation:

✔️Find HT:

Since it's a right triangle, we would apply the Pythagorean Theorem given as c² = a² + b²

Where,

a = HW = 15 cm

b = WT = 8 cm

c = HT

Plug in the values:

HT² = 15² + 8²

HT² = 289

HT = √289

HT = 17 cm

✔️Find <T by applying trigonometric ratio formula:

Recall: SOH CAH TOA

Reference angle (θ) = <T

HW = 15 cm = Opposite side length

WT = 8 cm = Adjacent side length

Apply CAH:

Cos θ = Adj/Hyp

Substitute

Cos T = 8/15

T = \( cos^{-1}(0.5333) \)

T ≈ 58°

✔️Find <H:

Sun of interior angles of a triangle = 180°

Therefore,

m<H + m<T + m<W = 180°

Substitute

m<H + 58° + 90° = 180°

m<H + 148° = 180°

m<H = 180° - 148°
