Answer:

Kimi saw 5 sheep and 8 chickens.

Step-by-step explanation:

ok 13 animals so

c+s= 13

chicken= 2 legs

sheep = 4 legs

2c+4s = 36

factor out the 2 since all of them are even numbers

2(c+2s) = 2(18)

c+2s = 18

subtractfrom the second

c+2s = 18

- c+2s = 13

s = 5

c+5 = 13

13

- 5

= 8.

so 5 sheep and 8 chickens

The party cost for 19 guests is 95 dollars.

We assume there is a proportional relation between the number of guests and the cost.

y is the cost and x the number of guests, then we can write:

y = k*x

k is the unit rate.

We know that it costs $20 to invite 4 people, then:

20 = k*4

20/4 = k

5 = k

Then the relation is:

y = 5*x

So, if x = 19 we will have:

y = 5*19 = 95

The cost for 19 guests is $95.

False. if you are given a graph with two shif table lines, the correct answer will always require you to move both lines.

In a graph with two shiftable lines, the correct answer may or may not require moving both lines. It depends on the specific scenario and the desired outcome or conditions that need to be met.

When working with shiftable lines, shifting refers to changing the position of the lines on the graph by adjusting their slope or intercept. The purpose of shifting the lines is often to satisfy certain criteria or align them with specific points or patterns on the graph.

In some cases, achieving the desired outcome may only require shifting one of the lines. This can happen when one line already aligns with the desired points or pattern, and the other line can remain fixed. Moving both lines may not be necessary or could result in an undesired configuration.

However, there are also situations where both lines need to be shifted to achieve the desired result. This can occur when the relationship between the lines or the positioning of the lines relative to the graph requires adjustments to both lines.

Ultimately, the key is to carefully analyze the graph, understand the relationship between the lines, and identify the specific criteria or conditions that need to be met. This analysis will guide the decision of whether one or both lines should be shifted to obtain the correct answer.

Complete Question:

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Types of movies (drama, comedy, adventure, documentary, etc.).

Choose the correct answer below.

A. The nominal level of measurement is most appropriate because data cannot be arranged in an ordering scheme.

B. The ratio level of measurement is most appropriate because ratio are meaningful, and is also a natural zero.

C. The ordinary level of measurement is most appropriate because categories are ordered, but difference cannot be found or are meaningless.

D. The interval level of measurement is most appropriate because differences are meaningful, but there is no natural zero.

Answer:

A. The nominal level of measurement is most appropriate because data cannot be arranged in an ordering scheme.

Step-by-step explanation:

A level of measurement can be defined as a classification which is used to illustrate the attributes of the values assigned to variables. There are four (4) basic levels of measurement for a variable and these are;

1. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

2. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

3. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

4. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

Hence, the nominal level of measurement is the most appropriate for types of movies (drama, comedy, adventure, documentary, etc.) because data cannot be arranged in an ordering scheme. A nominal level of measurement consists of quantitative variables.

Both x values have a coefficient with the exact value of three. This would make it easy to eliminate to solve for y.

what are the options?

the equivalent expression is 19

1.) 10x-5=y

2.) $85

3.) 5.25 yards of fabric.

1.) To write an equation for this problem, we need to figure out what every value means:

the variable x, represents the amount of yards of fabric you can buy

the variable y, represents the total amount of money after you found out (x) or the amount of yards of fabric.

1 yard of fabric equals $10, and we have a $5 coupon (-5)

Our equation is:

10x-5=y

This equation represents the relationship between the total cost of fabric, and the amount that you can buy.

2. In order to solve this problem we need to use our equation, one value is given which is 9.

9 represents x, the amount of yards of fabric.

Substitute 9 into x:

10(9)-5=y

90-5=y

85=y

85 represents the cost of 9 yards of fabric, including the $5 coupon.

3.) This problem is similar to #2, although it's flipped.

The value given is $47.50, which represents (y), the total amount of money after (x) was found out.

But, we need to figure out (x).

Substitute $47.50 into (y):

10(x)-5=$47.50

Next, we need to figure out x by solving the opposite.

Adding the coupon to our answer can represent 10(x).

$47.50+5=52.50

10(x)=52.50

Lastly, divide both sides of the equation by 10.

10(x) / 10=52.50 /10

x=5.25

5.25 represents the amount of yards of fabric purchased if you paid $47.50.

The SQL aggregate function that gives the arithmetic mean for a specific column is `AVG()`.

SQL (Structured Query Language) aggregate functions are functions that operate on a set of values and return a single value as a result. These functions are used in SQL queries to perform calculations on groups of rows in a database table.

There are several common aggregate functions in SQL, including:

1. `COUNT()` - returns the number of rows in a table or the number of non-null values in a specific column.

2. `SUM()` - calculates the sum of values in a specified column.

3. `AVG()` - calculates the average value of values in a specified column.

4. `MAX()` - returns the maximum value in a specified column.

5. `MIN()` - returns the minimum value in a specified column.

Aggregate functions are typically used with the `GROUP BY` clause in SQL queries to group the data based on one or more columns and then apply the aggregate function to each group.

Figure II is a trapzium.

a and b  are the parallel sides. a = 21 m

b = 20 - 5 = 15 m

h =  3 + 4 = 7 m

\(\text{area of figure 2 = $\dfrac{(a + b)*h}{2}$}\)

                       \(=\dfrac{(21+15)*7}{2}\\\\\\=\dfrac{36*7}{2}\\\\\\= 18*7\\\\= 126 \ m^{2}\)

Area of the figure = 20 + 126

Answer:

146 m²

Step-by-step explanation:

Formulae

Area of a rectangle = width x length

Area of a triangle = 1/2 x base x height

Divide the figure into 2 rectangles and a triangle (see attachment).

Area of Rectangle 1 = 4 x 5 = 20 m²

Area of Rectangle 2 = (3 + 4) x (20 - 5) = 105 m²

Area of triangle 3 = 1/2 x (21 + 5 - 20) x (3 + 4) = 21 m²

The main difference is interest charged for a payday loan is typically over a short period, whereas  credit card represents the annualized interest rate over a year.

The payday loan interest is a one-time charge, while the credit card APR accumulates over time if the balance is not paid in full.

For a payday loan, the 30% interest is typically charged over a short period, often within a few weeks.

This means that if you borrow $100, you would need to repay $130, including the $30 interest, within that short timeframe.

On the other hand, a 30% APR on a credit card represents the annualized interest rate charged on the outstanding balance. This interest is spread out over a year.

If you have an outstanding balance of $100 on a credit card with a 30% APR, the interest charged over a year would be $30.

In summary, the main difference is that the 30% interest charged for a payday loan is typically applied over a short period, whereas the 30% APR on a credit card represents the annualized interest rate over a year.

The function f^(-1)(P) allows us to find the time at which the population reaches a certain value, given the growth model provided by f(t).This means that the population will be 20 million in approximately 34.657 years.

We set P equal to f(t):
P = 10e^(0.02t)
ln(P/10) = 0.02t
t = (1/0.02) ln(P/10)
t = 50 ln(P/10)
f^(-1)(P) = 50 ln(P/10).

This function gives us the time (in years) at which the population is equal to P million. So, for example, if we want to know when the population is 20 million, we can plug P = 20 into the formula:
f^(-1)(20) = 50 ln(20/10) = 34.657
