Answer:

You will need to pay 33 dollars for 11 plants.

Step-by-step explanation:

We can use ratios to solve this problem.

$6                 x dollars

------------  = ------------

2 plants           11 plants

Using cross products:

6*11 = 2 *x

66 =2x

Divide each side by 2.

66/2 = 2x/2

33 = x

You will need to pay 33 dollars for 11 plants.

Answer:

$ 33

Step-by-step explanation:

2 plants ⇒ cost $6

Therefore, 1 plant would cost

$6/2 = $3.

To find the cost for 11 plants, we multiply the cost per plant by the number of plants:

Cost for 11 plants = $ 3 × 11 = $ 33.

So, you would pay $ 33 for 11 plants at the given price.

I think its that

Answer:

y = (1/2) x + 3

Step-by-step explanation:

The equation of linear functions is y = m x + b

In this case, we know m = 1/2 , and have point (4,5). We only need to find our y-intercept or b value.

What we can do is substitute what we know into our formula which will give us variable b, or the y-intercept. That will look like:

5 = (1/2) * 4 + b

5 = 2 + b

3 = b

So, the equation is y = (1/2) x + 3 :)

Answer:

\(21.7 x 10^5\)

Step-by-step explanation:

(6.2 x 10²) x (3.5 x 10³)

First, multiply the coefficients: 6.2 x 3.5 = 21.7.

Then, add the exponents: 10² x 10³ = 10^(2+3) = 10^5.

Therefore, the result is 21.7 x 10^5.

The value of y in the triangle is 2√10 units.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

The value of y can be found using the similar triangle ratios as follows:

Hence,

8 / y = y / 5

cross multiply

y² = 8 × 5

y²= 40

square root both sides of the equation

y = √40

Therefore,

y = 2√10 units

Answer:

Step-by-step explanation:

You want the coordinates of the vertices of triangle PKY after it has been rotated 180° CW about the origin.

Rotation about the origin by 180° is equivalent to reflection across the origin. Rotation clockwise or counterclockwise has the same result. The transformation of coordinates is ...

  (x, y) ⇒ (-x, -y) . . . . . . only the sign changes

Applying this transformation to the given points, you have ...

  P(-5, -3) ⇒ P'(5, 3)

  K(-3, -1) ⇒ K'(3, 1)

  Y(-1, -4) ⇒ Y'(1, 4)

Highest point reached by object is max = 2.5 ft

Highest point reached is, 100 ft

Time taken to reach highest point = 2.5 sec

The object hit ground after 5 seconds.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

f (x) = - 16x² + 80x

Where, x is time in seconds after it kicked.

Highest point reached by object is max as;

f (x) = - 16x² + 80x

f ' (x) = - 32x + 80 = 0

x = 80/32

x = 2.5 ft

Hence, Highest point reached is,

= - 16 × 2.5² + 80 × 2.5

= - 100 + 200

= 100 ft

Time taken to reach highest point = 2.5 sec

And, When object hit ground, height, f (x) = 0

f (x) = - 16x² + 80x = 0

- 16x² + 80x = 0

16x² = 80x

16x = 80

x = 5 seconds

Thus, Highest point reached by object is max = 2.5 ft

Highest point reached is, 100 ft

Time taken to reach highest point = 2.5 sec

The object hit ground after 5 seconds.

Let's say this school has 1000 students.

5/8 of that amount is (5/8)*1000 = 625. There are 625 students who play sports.

Then we take 2/5 of this to get (2/5)*625 = 250 to represent the number of people who play soccer.

The last step is to divide that result over the original number of students. Reduce as much as possible.

250/1000 = 25/100 = 1/4

Therefore, 1/4 of all the students play soccer

The mean absolute deviation is $106.6.

Given the table shows the amount Bill spent on 5 days last week.

DayAmount12622313126534To find the mean of the amount he spent: The formula for calculating the mean of a given set of values is mean=∑x/n where x represents the values, n represents the number of values, and ∑x represents the sum of the values.

Mean=total sum of values/total number of values Mean=(26+23+31+26+534)/5Mean=640/5Mean=128So,

the mean of the amount he spent is $128.To find the mean absolute deviation: The mean absolute deviation (MAD) is the average distance between each data value and the mean. MAD shows how much the data set deviates from the mean. The formula for calculating the MAD is MAD=∑|xi−m|/n where xi represents the values, m represents the mean, and n represents the number of values. So, the calculation for each day is:

Day Amount Absolute deviation from mean1 26 |128-26|=102 23 |128-23|=105 31 |128-31|=974 26 |128-26|=102 534 |128-534|=406

The given table does not represent a function. The correct answer is D. No, because one x-value corresponds to two different y-values.

To determine if the table represents a function, we need to check if every x-value corresponds to exactly one y-value. Let's analyze the given table:

x | y

-------

O | 1

X | 4

2 | 3

3 | 2

3 | 5

5 |

From the table, we can see that the x-values are not unique. Both the values 3 and 4 appear twice in the x-column, but they have different corresponding y-values.

This violates the definition of a function, which states that each input (x-value) should have only one output (y-value).

Therefore, the given table does not represent a function.

The correct answer is D. No, because one x-value corresponds to two different y-values.

Answer:

Step-by-step explanation:

A function with a domain of (-♾️,♾️) and a range of (5,♾️) means that the input values can be any real number, and the output values must be greater than or equal to 5, but can be any real number larger than 5.

The following functions have a domain of (-♾️,♾️) and a range of (5,♾️):

f(x) = 5 + x

f(x) = 5 + e^x (where e is the mathematical constant approximately equal to 2.71828)

f(x) = 5 + ln(x+1) (where ln denotes the natural logarithm, which is defined only for positive values of x+1)

Note that these are not the only functions that could have this domain and range, but they are some examples.

Given statement solution is :- Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.

To analyze the steady matrix for this situation, let's consider the two groups of customers: those who turn in tickets and those who do not turn in tickets.

Let's denote the proportion of customers who turn in tickets as X and the proportion of customers who do not turn in tickets as Y.

According to the given information:

40% of the customers who turn in tickets do not turn in tickets the following week. This means that 60% of the customers who turn in tickets will turn in tickets again the following week.

30% of the customers who do not turn in tickets will turn in tickets the following week. This means that 70% of the customers who do not turn in tickets will continue not turning in tickets the following week.

Based on these percentages, we can construct the steady matrix:

     |  Customers turning in tickets (X) | Customers not turning in tickets (Y) |

Next week 0.6 0.3

This week 0.4 0.7

Interpreting the steady matrix:

The value 0.6 in the top left cell represents the proportion of customers who turn in tickets this week and will turn in tickets again next week.

The value 0.3 in the top right cell represents the proportion of customers who turn in tickets this week but will not turn in tickets next week.

The value 0.4 in the bottom left cell represents the proportion of customers who do not turn in tickets this week but will turn in tickets next week.

The value 0.7 in the bottom right cell represents the proportion of customers who do not turn in tickets this week and will continue not turning in tickets next week.

These values describe the transition probabilities between the two customer groups. For example, if there are 100 customers in total, 60 of them will turn in tickets next week, and 40 of them will not. Similarly, 30 customers who turn in tickets this week will not do so next week, while 70 customers who do not turn in tickets this week will continue to not turn them in next week.

The steady matrix provides a snapshot of the probabilities of transitioning between the two states (turning in tickets or not turning in tickets) in the long run, assuming these probabilities remain constant over time.
