suppose the session table is set up as follows. is this design correct? if not, in which normal form would you correct it?

Answers

Answer 1

As per normalization, the session table uses the third normal form

Normalization is an important step in designing a database, as it helps to eliminate issues such as data integrity and redundancy. This is achieved through a series of steps, known as normalization.

The Sports Physical Therapy Center database has a table named Session that keeps track of all therapy appointments at the center. The table contains various pieces of information such as the session number, date, patient number, length of session, therapist ID, therapist's last and first name, and the therapy code.

The Session table is used to check if there are any design issues and to apply the necessary normalization steps to fix these issues and ensure data is stored in an organized manner.

Thorough this we have identified that the 3rd normal for is used here.

A gardener with 200 m available fencing wishes to enclose a
rectangular field and then divide it in two plots with a fence
parallel to one of the sides. What is the largest area that can be
enclose

Answers

The largest area that can be enclosed with 200 meters of fencing is 2500 square meters.

Let the length of the rectangular field be L and the width be W.

Then the perimeter is:
2L + 2W = 200
Simplifying, we get:
L + W = 100
We want to maximize the area A = LW of the rectangular field, subject to the constraint above.

To do this, we can solve for one of the variables in terms of the other:
L = 100 - W
Substituting into the area equation, we get:
A = (100 - W)W = 100W - W^2
Now we have a quadratic function for the area, which we can maximize by finding its vertex. The vertex occurs at W = -b/2a, where a = -1 and b = 100.
W = -100/-2 = 50
So the width of the rectangular field that maximizes the area is 50 meters. Plugging this back into the constraint equation, we get:
L + 50 = 100
L = 50
So the length of the rectangular field is also 50 meters.

The maximum area is then:
A = LW = 50 x 50 = 2500 square meters

Write the equation of the line that goes through (4,5)
and (8,7).

a)x+5 a) y = 1/2x+4,5
b) y = /2x+3
c) y=2x-4.5
d) y=2x-3

Answers

To find the equation of a line that goes through two points, you can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where "m" is the slope of the line and "b" is the y-intercept (the point where the line crosses the y-axis).

To find the slope of the line, you can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are two points on the line.

In this case, we are given the points (4, 5) and (8, 7), so we can plug these values into the formula for the slope:

m = (7 - 5) / (8 - 4)

= 2 / 4

= 1/2

Now that we know the slope of the line, we can use the point-slope form of the equation of a line to find the equation of the line:

y - y1 = m(x - x1)

where (x1, y1) is any point on the line and "m" is the slope of the line.

In this case, we are given the point (4, 5), so we can plug these values into the formula:

y - 5 = (1/2)(x - 4)

y = (1/2)x + 3

So, the equation of the line that goes through (4,5) and (8,7) is y = (1/2)x + 3.

Therefore, the correct answer is (b) y = /2x+3.

suppose a basketball player makes 80% of his free throws. assume that free throw shots are independent of one another. suppose this player gets to shoot four free throws. find the probability that he makes all four free throws.

Answers

The probability that a basketball player makes all four of his free throws when the probability of making one is 80% is 0.4096.

This is calculated using the binomial probability formula, which states that the probability of k successes in n trials is given by the following:

P(k successes in n trials) = $(n!/(k!(n-k)!))\timespk(1-p)(n-k)$

In this case, the probability of making a single free throw is 80% (0.8),

so we can plug this into the formula.

We know that the player is taking 4 free throws, so k is 4 and n is also 4.

Plugging these values into the formula, we get:

P(4 successes in 4 trials) = $(4!/(4!(4-4)!))\times 0.84(1-0.8)(4-4) = 0.4096$

the pay rate and hours worked are given below. use this information to determine the following. the gross earnings federal taxes (assuming 18% of gross earnings) state taxes (assuming 4% of gross earnings) social security deduction (assuming 7.05% of gross earnings) total deductions net pay earnings description rate hours current regular $7.50 30.0 $ taxes and deductions fed tax $ state tax $ soc sec $ total deductions $ net pay $

Answers

The gross earnings are $225, federal taxes are $40.50, state taxes are $9, social security deduction is $15.86, total deductions are $65.36, and the net pay is $159.64.

The gross earnings are determined by multiplying the pay rate by the number of hours worked.

Federal taxes, state taxes, and social security deductions are calculated by applying the respective tax rates to the gross earnings.

Total deductions are the sum of federal taxes, state taxes, and social security deductions.

Net pay is obtained by subtracting the total deductions from the gross earnings.

To calculate the gross earnings, we multiply the pay rate of $7.50 by the number of hours worked, which is 30.

Therefore, the gross earnings are $7.50 * 30 = $225.

Next, we can calculate the federal taxes by applying the tax rate of 18% to the gross earnings.

The federal taxes amount to 18% * $225 = $40.50.

Similarly, the state taxes can be calculated by applying the tax rate of 4% to the gross earnings.

The state taxes amount to 4% * $225 = $9.

To determine the social security deduction, we apply the tax rate of 7.05% to the gross earnings.

The social security deduction amounts to 7.05% * $225 = $15.86.

The total deductions are the sum of the federal taxes, state taxes, and social security deduction.

Thus, the total deductions are $40.50 + $9 + $15.86 = $65.36.

Finally, to calculate the net pay, we subtract the total deductions from the gross earnings.

Therefore, the net pay is $225 - $65.36 = $159.64.

In conclusion, the gross earnings are $225, federal taxes are $40.50, state taxes are $9, social security deduction is $15.86, total deductions are $65.36, and the net pay is $159.64.

Find the rate of change of the area of a square with respect to the length z, the diagonal of the square. What is the rate when z = 3? a) dA/dz = z; rate = 6 b) dA/dz = zroot2; rate = 3 root2 c) dA/dz = 2z; rate = 3 d) dA/dz = z; rate = 3 e) dA/dz = 2z; rate = 6

Answers

The rate of change of the area of a square with respect to the length z, the diagonal of the square is dA/dz = 2z; rate = 6. The correct answer is C.

We know that the area A of a square is given by A = s², where s is the length of the sides of the square. Also, we know that the diagonal of the square (z) is related to the sides by the Pythagorean theorem: s² + s² = z² or 2s² = z² or s² = z²/2.

Taking the derivative of both sides of the equation s² = z²/2 with respect to z, we get:

2s ds/dz = 2z/2

s ds/dz = z

Now, since the area A is given by A = s², we can take the derivative of both sides of this equation with respect to z:

dA/dz = d/dz (s²) = 2s ds/dz

Substituting the value of s ds/dz obtained earlier, we get:

dA/dz = 2s (z/s) = 2z

Therefore, the correct option is (c) dA/dz = 2z, and the rate of change of the area of the square with respect to the length z is 2z. When z = 3, the rate of change is 2(3) = 6. So, the answer is (c) dA/dz = 2z; rate = 6.

The solutions to the variables in the equation [x¦7]+[3y¦(-x)]=[16¦12] are x = -5 and y = 7

How to determine the solutions to the variables

From the question, we have the following parameters that can be used in our computation:

[x¦7]+[3y¦(-x)]=[16¦12]

When the equation is splitted, we have

x + 3y = 16

7 - x = 12

Add the equations to eliminate y

So, we have

3y + 7 = 28

So, we have

3y = 21

Divide

y = 7

Recall that

7 - x = 12

So, we have

x = -5

Hence, the solutions to the variables are x = -5 and y = 7

From the given information, cholesterol level X follows the N(222, 37) distribution.

The probability of having borderline high cholesterol (between 200 and 240 mg/dl) can be calculated by using the z-score formula as follows:

z = (x - μ) / σ

For lower limit x1 = 200, z1 = (200 - 222) / 37 = -0.595

For upper limit x2 = 240, z2 = (240 - 222) / 37 = 0.486

The probability of having borderline high cholesterol (between 200 and 240 mg/dl) can be computed as

P(200 ≤ X ≤ 240) = P(z1 ≤ Z ≤ z2) = P(Z ≤ 0.486) - P(Z ≤ -0.595) = 0.683 - 0.277 = 0.406

In this population, 90% of men have a cholesterol level that is at most X90.The z-score corresponding to a cholesterol level of X90 can be calculated as follows:

z = (x - μ) / σ

Since the z-score separates the area under the normal distribution curve into two parts, that is, from the left of the z-value to the mean, and from the right of the z-value to the mean.

So, for a left-tailed test, we find the z-score such that the area from the left of the z-score to the mean is 0.90.

By using the standard normal distribution table,

we get the z-score as 1.28.z = (x - μ) / σ1.28 = (X90 - 222) / 37X90 = 222 + 1.28 × 37 = 274.36 ≈ 274

The cholesterol level of 90% of men in this population is at most 274 mg/dl.

The distributions that we can consider to be approximately normal are the sampling distribution of mean BMI for random samples of 60 adults and the sampling distribution of mean BMI for random samples of 9 adults.

The reason for considering these distributions to be approximately normal is that according to the Central Limit Theorem, if a sample consists of a large number of observations, that is, at least 30, then its sample mean distribution is approximately normal.

Determine whether or not the vector field is conservative. If it is conservative, find a function f such that

F(x, y, z) = eyzi + xzeyzj + xyeyzk

Answers

The vector field F(x, y, z) = eyzi + xzeyzj + xyeyzk is conservative, and a potential function f is f(x, y, z) = xeyzi + xy²ezj + xyzek + C

How to determine vector field?

To determine if a vector field is conservative, we need to check if its curl is zero. If the curl is zero, it implies that the vector field can be expressed as the gradient of a scalar function.

Taking the curl of F, we have:

curl(F) = (∂F₃/∂y - ∂F₂/∂z)i + (∂F₁/∂z - ∂F₃/∂x)j + (∂F₂/∂x - ∂F₁/∂y)k

Evaluating the partial derivatives, we get:

curl(F) = (z - z) i + (x - x) j + (y - y) k

= 0

Since the curl of F is zero, the vector field F is conservative. We can find a potential function f by integrating each component of F with respect to its respective variable:

f(x, y, z) = ∫eyzi dx = xeyzi + g₁(y, z)

∫xzeyzj dy = xy²ezj + g₂(x, z)

∫xyeyzk dz = xyzek + g₃(x, y)

Here, g₁, g₂, and g₃ are arbitrary functions of the remaining variables. Combining these results, we obtain the potential function:

f(x, y, z) = xeyzi + xy²ezj + xyzek + C

Where C is the constant of integration. Therefore, a potential function f exists for the given vector field F, and it is given by f(x, y, z) = xeyzi + xy²ezj + xyzek + C.
