The 900 grams is 75% of 1.200 kg (1,200 grams).

Evaluate those 900 grams is what percent of 1.200 kg (1,200 grams)?

We can solve this problem by converting both the quantities to the same units. We have

1 kg = 1000 grams.

1.200 kg = 1.200 × 1000

              = 1200 grams.

Then, the required percentage is as follows:

% = {900}/{1200} × 100

Now, we can simplify the above expression to get the answer. We have,

{900}/{1200} = {3}/{4}

Therefore,

% = {3}/{4} × 100

   = 75%

Hence, 900 grams is 75% of 1.200 kg (1,200 grams).

Thus, the answer is 75.

Answer:

1.50

Step-by-step explanation:

To find the mean of the probability distribution, we need to multiply each value of hours studied by its corresponding probability, then add up the products.

Mean = (0.5 x 0.07) + (1 x 0.2) + (1.5 x 0.46) + (2 x 0.2) + (2.5 x 0.07)

Mean = 0.035 + 0.2 + 0.69 + 0.4 + 0.175

Mean = 1.5

Therefore, the mean of the probability distribution is 1.5.

Answer:

The 3 consecutive odd numbers are -67, -65 and -63 and the least of them is -67.

Explanation:

Consecutive odd numbers means that the next number will be two more than the previous one.

Let the 1st number be y, the other 2 consecutive odd numbers will be y + 2 and y + 4.

We're also told that the sum of the 3 numbers is -195, so our equation can be written thus;

Let's collect like terms and solve for y;

So our 1st number is -67.

Let's go ahead and find the other 2 numbers;

2nd number: y + 2 = -67 + 2 = -65

3rd number: y + 4 = -67 + 4 = -63

Therefore, the 3 consecutive odd numbers are -67, -65 and -63 and the least of them is -67.

The question is incomplete, as the graph is not given.

The general step to calculate slope and y intercept is as follows;

Assume any two points on the graph are:

\((x_1,y_1) = (5,1)\)

\((x_2,y_2) = (1,4)\)

The slope (m) is:

\(m = \frac{y_2 -y_1}{x_2 - x_1}\)

\(m = \frac{4 -1}{1-5}\)

\(m = \frac{3}{-4}\)

\(m = -\frac{3}{4}\)

The equation of the graph is:

\(y = m(x - x_1) + y_1\)

This gives:

\(y = -\frac{3}{4}(x - 5) + 1\)

\(y = -\frac{3}{4}x +\frac{15}{4} + 1\)

\(y = -\frac{3}{4}x +\frac{15+4}{4}\)

\(y = -\frac{3}{4}x +\frac{19}{4}\)

To calculate the y intercept; set \(x = 0\)

\(y = -\frac{3}{4}*0 +\frac{19}{4}\)

\(y = \frac{19}{4}\) ---- y intercept

The value of the error for Z, where x = 5.9 +/- 0.5 and y = 2.1 +/- 0.2, with one decimal place is 4.

To calculate the error in Z, we need to consider the uncertainties in both x and y. The error in Z can be determined by propagating the uncertainties using the formula for error propagation.

In this case, Z is given by the equation Z = x/y. To propagate the uncertainties, we use the formula for relative error:

ΔZ/Z = sqrt((Δx/x)^2 + (Δy/y)^2)

Given the uncertainties Δx = 0.5 and Δy = 0.2, and the values x = 5.9 and y = 2.1, we substitute these values into the formula:

ΔZ/Z = sqrt((0.5/5.9)^2 + (0.2/2.1)^2) = sqrt(0.0089 + 0.0181) ≈ 0.134

Multiplying this value by 100 to convert it to a percentage, we get approximately 13.4%. Rounding to one decimal place, the value of the error is 4.

Therefore, the value of the error for Z, with one decimal place, is 4.

The method of undetermined coefficients cannot be applied to find a particular solution of the given equation y''(θ) + 3y'(θ) - y(θ) = sec(θ) since sec(θ) is not an elementary function that fits the criteria for the method.

To determine whether the method of undetermined coefficients can be applied to find a particular solution for the given equation y''(θ) + 3y'(θ) - y(θ) = sec(θ), we need to consider the nature of the non-homogeneous term on the right-hand side (sec(θ)) and the compatibility with the method.

The method of undetermined coefficients is applicable when the non-homogeneous term is a linear combination of elementary functions such as polynomials, exponential functions, sine, cosine, and their linear combinations.

However, the term sec(θ) does not fall into this category.

Secant (sec(θ)) is not an elementary function. It is the reciprocal of the cosine function and has a non-trivial behavior. The method of undetermined coefficients relies on the assumption that the particular solution can be expressed as a sum of specific functions, each corresponding to the elementary functions in the non-homogeneous term.

Since sec(θ) does not fit this criterion, the method of undetermined coefficients cannot be directly applied to find a particular solution.

In this case, an alternative approach, such as variation of parameters or integrating factors, may be more appropriate for finding a particular solution for the given equation.

These methods are used to handle non-elementary non-homogeneous terms by introducing additional parameters or transforming the equation.

Therefore, in the given equation y''(θ) + 3y'(θ) - y(θ) = sec(θ), the method of undetermined coefficients cannot be directly applied to find a particular solution.

According to the uniform distribution, there is a 0.625 = 62.5% chance that a randomly chosen passenger will have to wait longer than 2.25 minutes.

The boundaries of a uniform distribution are a and b.

The likelihood of discovering a value greater than x is:

P(X > x)=b-x/b-a

In this issue, the distribution of time is evenly spaced between 0 and 6 minutes, therefore

a=0 b=6

P(X > x)= 6-2.25/6-0

=0.625

Answer:

The value of x = 36°, while the value of y = 72°.

Step-by-step explanation:

All of these angles add up to 360°.

Opposite angles are always equivalent, so the angle opposing x would be 36°, which means x = 36°.

360 - 2(36) = 288

288/4= 72

To check:

(72 * 4) + 2(36) = 360

The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16 hours.

In this case, we are estimating the difference in population means between two groups - upperclassmen and underclassmen. The point estimate is calculated by subtracting the sample mean of the underclassmen from the sample mean of the upperclassmen, which gives us

0.76 - 0.60 = 0.16.
the point estimate of the difference in population mean exercised between underclassmen and upperclassmen is 0.16 hours, which was calculated by subtracting the sample mean of underclassmen from the sample mean of upperclassmen.
Point Estimate = (Sample Mean of Upperclassmen) - (Sample Mean of Underclassmen)
Point Estimate = (0.76) - (0.60)
Point Estimate = 0.16

Hence, the point estimate of 0.16 suggests that, on average, upperclassmen exercised 0.16 hours more than underclassmen in the past 24 hours. This is a rough estimate of the difference between the two population means based on the provided sample data.

Answer:

The x coordinate is 2

Step-by-step explanation:

Given

\(A = (-2,5)\)

\(C = (6,-1)\)

Required

Determine the x coordinate of B

Since B is the bisector of AC, then B is the midpoint and will be calculated using;

\(B(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})\)

Considering the x coordinates alone;

\(x = \frac{x_1 + x_2}{2}\)

Where

\((x_1,y_1) = (-2,5)\)    and     \((x_2,y_2) = (6,-1)\)

Substitute values for x1 and x2

\(x = \frac{-2 + 6}{2}\)

Depending on the size and thickness of the box, a certain amount of metal is required to cast a cubical metal box.

Depending on the size and thickness of the box, a certain amount of metal is required to cast a cubical metal box. In general, more metal is required for larger, thicker boxes. One must first calculate the box's volume in order to determine how much metal is required. The box's length, width, and height can be multiplied together to get this. The thickness of the metal must next be determined. The total amount of metal required can be estimated by multiplying the volume of the box by the thickness of the metal once the volume and thickness of the metal have been established. For instance, consider a box with dimensions of 6 inches long, 6 inches wide, and 6 inches high and a metal thickness.

The balance in the account after 1 year is approximately $1037.05, after 5 years is approximately $1191.82, and after 20 years is approximately $2213.84 and the Annual Percentage Yield (APY) for the account is approximately 3.87%.

To compute the balance in the account after a certain time period using the formula for continuous compounding, we can use the following formula:

A = P * e^(rt)

Where:

A = Balance in the account

P = Principal amount (initial deposit)

e = Euler's number (approximately 2.71828)

r = Annual percentage rate (APR) as a decimal

t = Time period in years

As per data:

P = $1000, r = 3.75% (or 0.0375 as a decimal)

To calculate the balance after 1 year, we substitute the values into the formula:

A = 1000 * e^(0.0375 * 1)

To calculate the balance after 5 years, we substitute the values into the formula:

A = 1000 * e^(0.0375 * 5)

To calculate the balance after 20 years, we substitute the values into the formula:

A = 1000 * e^(0.0375 * 20)

Now, let's calculate the balances:

After 1 year:

A ≈ $1000 * e^(0.0375 * 1)

  = $1000 * e^0.0375

  ≈ $1037.05 (rounded to the nearest cent)

After 5 years:

A ≈ $1000 * e^(0.0375 * 5)

  = $1000 * e^0.1875

  ≈ $1191.82 (rounded to the nearest cent)

After 20 years:

A ≈ $1000 * e^(0.0375 * 20)

   = $1000 * e^0.75

   ≈ $2213.84 (rounded to the nearest cent)

To find the Annual Percentage Yield (APY) for the account, we can use the formula:

APY = (e^(r) - 1) * 100%

Where r is the APR as a decimal.

Substituting the value for r into the formula: APY = (e^(0.0375) - 1) * 100% Calculating the APY:

APY ≈ (e^0.0375 - 1) * 100%

       ≈ (1.0387 - 1) * 100%

       ≈ 3.87% (rounded to the nearest hundredth)

Therefore, the after one year, the balance is roughly $1037.05, after five years, roughly $1191.82, and after twenty years, roughly $2213.84. The account's annual percentage yield (APY) is roughly 3.87%.
