Yes, when dealing with a multi-value attribute with a variable number of values that need to be processed independently.

Yes, when dealing with a multi-value attribute with a variable number of values that need to be processed independently, it is recommended to consider creating a new dependent entity to represent the values. This can help to simplify the design and make it easier to manage and maintain. The new entity can be linked to the original entity through a relationship, allowing each value to be processed independently while still maintaining the integrity of the data. Overall, this approach can improve the efficiency and effectiveness of the system, making it easier to work with and providing better results for the end user.

Answer:

Step-by-step explanation:

width:length =1:3

width:15=1:3

width =5

The width of the actual car is 45 feet.

Given that,

A automobile model is 3 feet long and 1 foot wide. Considering that the automobile is 15 feet long

To find : The width of the actual car

Model Car's Width (W) = 1 foot

Model Car's Length (L) = 3 feet

Actual Car's Length (l) = 15 feet

Actual Car's Width (w) = x feet

To solve,

We know that,

Product of Means = Product of Extremes which means ,

1 : 3 :: 15 : x

1 * x = 15 *3

x = 45.

Therefore, the Actual Car's Width (w) is 45 feet.

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

Answer:

(0,-6), (-2,0)

Step-by-step explanation:

-3x-y=6

-y=6+3x

y=-3x-6

when x=0, y=-6

when y=0 x=-2

The equation that describing how x and y are related is y = 2x + 7

From the given table we have to choose two points

The first point = (1, 9)

The second point = (2, 11)

The slope of the line is the change in y coordinate with respect to the change in x coordinate of the line

The slope of the line = \(\frac{y_2-y_1}{x_2-x_1}\)

Substitute the values in the equation

The slope of the line = (11-9) / 2 - 1

= 2 / 1

= 2

From the table

At x = 0 the value of y = 7

Therefore the y intercept = 7

The slope intercept form is

y = mx + b

Where m is the slope of the line

b is the y intercept

Then,

y = 2x + 7

Hence, the equation that describing how x and y are related is y = 2x + 7

What are arithmatic operations?

Arithmetic operations is a branch of mathematics, that involves the study of numbers, the operation of numbers that are useful in all the other branches of mathematics. It basically comprises operations such as Addition, Subtraction, Multiplication, and Division.

Let's start by finding the amount of money I receive from my allowance and how much more money I need to make to reach my goal:

Allowance per month = $60

Amount of money I need for social life = $260

Additional amount of money I need to make = $260 - $60 = $200

Now, let's divide the additional amount of money I need to make by the amount I make per hour to find how many hours I need to work:

$200 ÷ $7.50 per hour = 26.67 hours

Since we can't work a fraction of an hour, we need to round up to the nearest whole number.

Therefore, I would need to work at least 27 hours to make enough money to reach my goal.

Step-by-step explanation:

Answer:

c=13

Step-by-step explanation:

Hey There!

c+11=24

When looking at this problem you want to get the variable on one side (c) and the constant on the other ( any whole number)

as you can see we need to get rid of the 11 on the left side

to do that we subtract 11 but whatever you do to one side you have to do to the other side

11-11 cancels out

24-11=13

so we can conclude that

c=13

The z scores of 1.5, -0.5 and -2.0 corresponds with a raw score of 650, 450 and 300

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

Where x = raw score, μ = mean and σ = standard deviation.

Given that σ = 100, μ = 500, hence:

a) For z = 1.5:

1.5 = (x - 500)/100

x = 650

b) For z = -0.5:

-0.5 = (x - 500)/100

x = 450

c) For z = -2:

-2 = (x - 500)/100

x = 300

Is the relation a function: C. No, because for each input there is not exactly one output.

In Mathematics, a function is typically used for uniquely mapping an independent value (input variable or domain) to a dependent value (range or output variable).

This ultimately implies that, an independent value represents the value on the x-axis of a cartesian coordinate while a dependent value represents the value on the y-axis of a cartesian coordinate.

Since the independent value (12) is mapped to multiple dependent values (-4 and -2), we can logically deduce that the relation does not represent a function.

The area of a triangle is 96 sq. inches

Let base be b

Its altitude is 2 inches greater than five times its base.

a=5b+2

(5b+2)b=192

5b²+2b=192

5b²2+2b-192=0

On solving the quadrartic equation,

The general solution to the given differential equation is z(t) = C1*\(e^{(3t)}\) + C2*\(e^{(-3t)}\)

The given differential equation is a second-order linear homogeneous differential equation, which can be written as:

z'' + z' - 9z = 0

To find the general solution, we first need to solve the characteristic equation:

\(r^2\) + r - 9 = 0

By factoring or using the quadratic formula, we find the roots r1 and r2:

r1 = 3
r2 = -3

Since we have two distinct real roots, the general solution of the differential equation is:

z(t) = C1 * \(e^{(r1t)}\) + C2 * \(e^{(r2t)}\)
z(t) = C1 * \(e^{(3t)}\) + C2 * \(e^{(-3t)}\)

where C1 and C2 are arbitrary constants determined by initial conditions.

Answer: y = -1/3(x + 1)² + 4

Step-by-step explanation:

First of all, we know that the graph is going to be a parabola

So we can start off with the parent function, y = x²

Using vertex form, y = a(x - h)² + k, where the vertex is point (h, k):

we have the formula: y = a(x + 1)² + 4

If the parabola must pass through the point (2,1), we can substitute these for x and y in our equation to find a, and finish the problem:

1 = a(2 + 1)² + 4

-3 = a(3)²

-3 = 9a

a = -1/3

based on this, our final formula will be y = -1/3(x + 1)² + 4

If can't have a meaning as something can't decrease more than 100% of itself.

The statement that is meaningless is

There was a 120% decrease in the amount of water in a dam.

Option C is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

A percentage increase can be of any number.

A percentage decrease can not be below 100%.

Now,

A.

Michael is currently 6 years old and Norman is 18 years old. In 6 years, Michael will be 12 years old and Norman will be 24 years old.

Norman is 12 years older than Michael. To determine Michael's age we need to subtract 12 from the age Norman will be in 6 years. In 6 years, Norman will be twice as old as Michael.

Let N = Norman's age now

Let M = Michael's age now

N= M+ 12

N+ 6= 2 (M+6)

N- 12 = M

N+6=2(N- 12+6)

N+ 6 = 2(N-6)

N+ 6 = 2N - 12

18 = N

This means that in 6 years, Norman will be 24 years old. To determine Michael's age we need to subtract 12 from 24. This gives us 12, which is the age Michael will be in 6 years. Therefore, Michael is currently 6 years old and Norman is 18 years old.  In 6 years, Michael will be 12 years old and Norman will be 24 years old.
