what are the missing angles?

The length of the tangent in the circular curve is approximately 22.256 meters. To calculate the length of the tangent, we can use the formula:

Length of Tangent = External Distance / tan(Azimuthal Difference / 2)

Given that the external distance is 7.30 m and the azimuthal difference between the forward and back tangents is 37 degrees, we can substitute these values into the formula:

Length of Tangent = 7.30 m / tan(37 degrees / 2)

Now let's solve this expression step by step:

1. Calculate the value inside the tangent function:

  37 degrees / 2 = 18.5 degrees

2. Calculate the tangent of 18.5 degrees:

  tan(18.5 degrees) ≈ 0.328

3. Divide the external distance by the tangent value:

  Length of Tangent = 7.30 m / 0.328 ≈ 22.256 m

In conclusion, by substituting the given values into the formula and performing the calculations, we find that the length of the tangent is approximately 22.256 meters.

To determine which payment plan the real estate investor would prefer, we need to compare the present value of each payment option. Assuming a discount rate of 0%, meaning no time value of money is considered, we can directly compare the payment amounts.

1. Payment of $2,000 at the first of each month: This results in a total payment of $24,000 over the 12-month lease.

2. Upfront payment of $24,000: This option requires paying the full amount at the beginning of the lease.

3. Payment of $2,000 at the end of each month: Similar to option 1, this results in a total payment of $24,000 over the 12-month lease.

4. Upfront payment of $12,000 and $12,000 half-way through the lease: This option requires paying $12,000 at the beginning of the lease and another $12,000 halfway through the lease.

Since all the payment options have a total cost of $24,000, the real estate investor would likely prefer the payment plan that offers more flexibility or matches their cash flow preferences. Options 1 and 3 provide the investor with the option to pay monthly, while options 2 and 4 require a larger upfront payment. The choice would depend on the investor's financial situation and preferences.

(a) the sample mean is 0.0494 and the sample variance is 0.000016, (b) the upper quartile is 0.04775, and the lower quartile is 0.0510, (c) the sample median is 0.04975, (d) boxplot is attached, and (e) the 5th and 95th percentiles of the inside diameter are 0.03974 and 0.056995 respectively.

(a) The mean = sum of all values divided by the number of values

μ = (x1 + x2 + ..... + xn)/n

n = 20

μ = (0.0395 + 0.0443+ 0.0450 + ... + 0.0550 + 0.0571)/20

μ = 0.9878/20

μ = 0.0494

(b) Variance = sum of squared deviations from the mean divided by n-1

s² = {(x1-μ)² + (x2-μ)² + .... (xn - μ)²)/(n-1)

s² = {(0.0395-0.0494)² + (0.0443-0.0494)² + .... +(0.0571-0.0494)²}/19

s² = 0.000016

(b) The minimum is 0.0395 and the maximum is 0.0571.

since the number of data is even, the median will be the average of two middle values.

M = Q2 = (0.0496+0.0499)/2 = 0.04975

Now, the first quartile is the median of the data values below the median

so Q1 = (0.0470+0.0485)/2 = 0.04775

And third quartile will be the median of the data values above the median

Q3 = (0.0504+0.0516)/2 = 0.0510

(c) Since we know that the number of data values is even, the median will be the average of the two middle values of the data set

so M = (0.0496+0.0499)/2

or M = 0.04975

(d) The boxplot is at maximum and minimum values. It will start in Q1 and end in Q3 and has a vertical line at the median or Q2.

The boxplot is attached.

(e) The 5th percentile means 0.05(n+1)th data value

or = 0.05(20+1) = 1.05th data value

5th percentile = 0.0550 + 0.05(0.0443-0.0395) = 0.03974

similarly,

95th percentile = 0.0550 + 0.95(0.0571-0.0550) = 0.056995

Therefore, (a) the sample mean is 0.0494 and the sample variance is 0.000016, (b) the upper quartile is 0.04775, and the lower quartile is 0.0510, (c) the sample median is 0.04975, and (e) the 5th and 95th percentiles of the inside diameter are 0.03974 and 0.056995 respectively.

Answer:

B. (3, 14).

Step-by-step explanation:

Substitution means that you first solve for one variable, and then use that solution to find the other.

For example, if x = y, and x + 5 = 7, you can say that y + 5 = 7.

Now, moving on to the actual problem.

The first equation says that y = 6x - 4, and the second equation says y = 7x - 7.

That means for the first equation, instead of y, it is valid to say that 7x - 7 = 6x - 4.

7x - 7 = 6x - 4

7x - 6x = -4 + 7

x = 3.

You could put the x=3 into the y = 7x - 7 equation to find what the y-coordinate is.

y = 7 * 3 - 7

y = 21 - 7

y = 14.

And there you have your coordinates! (3, 14).

Step-by-step explanation:

To find the probability that a randomly selected worker has a retirement plan or health insurance, we need to add the probabilities of having a retirement plan and having health insurance and then subtract the probability of having both,

Since we don't want to count those workers twice. P(retirement plan or health insurance) = P(retirement plan) + P(health insurance) - P(both), P(retirement plan or health insurance) = 0.56 + 0.68 - 0.49, P(retirement plan or health insurance) = 0.75.

Therefore, the probability that a randomly selected worker has a retirement plan or health insurance is 0.75. we'll use the formula: P(A or B) = P(A) + P(B) - P(A and B), where A represents having a retirement plan, B represents having health insurance, and P(A and B) represents having both.

Given:
P(A) = 56% (retirement plan)
P(B) = 68% (health insurance)
P(A and B) = 49% (both)

Now we can plug these values into the formula: P(A or B) = 0.56 + 0.68 - 0.49 = 0.75, The probability that a randomly selected worker has a retirement plan or health insurance is 75%.

The solution of the given differential equation that satisfies the initial condition y(0) = 0 is 0 = (5/2)(0)² - (1/4)(ln(0))^2 - (5/3)(0)³ + C.

To find the solution of the given differential equation that satisfies the initial condition y(0) = 0, we will follow these steps,

1. Identify the differential equation: dy/dx = 5x - (ln(x)/2) - 5x²
2. Integrate both sides of the equation with respect to x.

Integral of dy = Integral of (5x - (ln(x)/2) - 5x²) dx

Since y(0) = 0, we have:

y(x) = Integral of (5x - (ln(x)/2) - 5x²) dx

3. Perform the integration:

y(x) = (5/2)x² - (1/4)(ln(x))^2 - (5/3)x³ + C

4. Determine the value of the constant C using the initial condition y(0) = 0:

0 = (5/2)(0)² - (1/4)(ln(0))^2 - (5/3)(0)³ + C

Since ln(0) is undefined, we cannot solve for C using the initial condition y(0) = 0. However, the given initial condition is not consistent with the differential equation, so there may be an error in the problem statement.

Solvent extraction yields 29% Xyz recovery, with initial feed containing 24 kg, and output concentration 7 kg per 28 kg.

To calculate the percent recovery, we need to determine the amount of Xyz recovered compared to the amount initially present in the feed. The initial amount of Xyz in the feed is 24 kg. After extraction, the amount of Xyz in the output is 7 kg. Therefore, the amount of Xyz recovered is 7 kg.

The percent recovery is calculated by dividing the amount of Xyz recovered (7 kg) by the initial amount of Xyz in the feed (24 kg) and multiplying by 100.

Percent recovery = (Amount of Xyz recovered / Initial amount of Xyz) x 100

                 = (7 kg / 24 kg) x 100

                 ≈ 29%

The percent recovery of Xyz in the solvent extraction process is approximately 29%. This means that around 29% of the initial amount of Xyz present in the feed was successfully extracted and recovered in the output.

Step-by-step explanation:

a) We can use the formula:

Amount earned per day = Amount kept + Amount given away

where "Amount earned per day" is the amount Tom earns in one day, "Amount kept" is the amount Tom keeps for himself each day, and "Amount given away" is the amount Tom gives to his mom each day.

Using the given information, we can plug in the values:

$40 = Amount kept + $8 x 4

Simplifying this equation, we get:

$40 = Amount kept + $32

Subtracting $32 from both sides, we get:

$8 = Amount kept

Now, we need to find the amount Tom gets paid each hour, which we can represent as "h". We know that Tom works 4 hours a day, and for each hour he works, he puts $8 aside for his mom. Therefore, the amount he earns each day can be expressed as:

Amount earned per day = h x 4

We also know that Tom keeps $8 for himself each day, so we can rewrite the equation as:

Amount earned per day = Amount kept + Amount given away

h x 4 = $8 + Amount given away

Substituting the value we found for "Amount kept", we get:

h x 4 = $8 + Amount given away

h x 4 = $8 + $32

h x 4 = $40

Dividing both sides by 4, we get:

h = $10

Therefore, Tom gets paid $10 per hour.

The equation -13x+12-(-13x+12)-13x+12 = -13x+12   is equivalent to the given expression that is -13x+12.

10x^2 - 23x + 12 = (5x - 3)(2x - 4) = 0

So the solutions to the equation are x = 3/5 or x = 2.

Therefore, this expression is not equivalent to -23x + 12 for all values of x.

10x^2 - 7x - 12 = 0 can be factored as (2x - 3)(5x + 4) = 0.

So the solutions to the equation are x = 3/2 or x = -4/5.

Therefore, this expression is not equivalent to -7x - 12 for all values of x.

-13x+12-(-13x+12)-13x+12  = -13x+12

-13x+12  = -13x+12

This expression is equivalent to -13x+12 .

7x^2 - 23x - 77 = (7x + 11)(x - 7) = 0

So the solutions to the equation are x = -11/7 or x = 7.

Therefore, this expression is not equivalent to -23x - 7 for all value x.

The given expressions of each case are not equivalent to the given equations for all values of x, except −13x+12-(-13x+12)-13x+12  = -13x+12 which is equivalent to -13x+12 .

sin(x) = \(\frac{7}{25}\)

x = 16.26°

Step-by-step explanation:

First use Pythagorean theorem to find the length of the hypotenuse. Use \(a^2 + b^2 = c^2\). Since we know a and b we can plug in to find c. When we plug in we get: \((7)^2 + (24)^2 = c^2\). When we solve this out we get 25 = c.

Now that we know the value of c, we also know sin(x) = \(\frac{opposite}{hypotenuse}\). Using this we see that sin(x) = \(\frac{7}{25}\).

To get the exact degree value of x, take the inverse sin of \(\frac{7}{25}\):

\(sin^-1(\frac{7}{25})\) which gives us 16.26020° rounded to 16.26°
