Make a point where it can be at 7 and 4.

Basically, put a point 4 or 5 blocks right of the 7.

Next, put a point where it can be at 21 and 12.

Basically, put a point 11 or 12 block right of the 21.

Answer: You will plot (0,0) which is the beginning, then plot (4,7), then if you multiply 7 times 2 you get 14 flowers. With those 14 flowers you will put them on (8,14) 8 minutes 14 flowers, lastly you will put 12 minutes and 21 flowers down which will be (12,21). since there are 21 flowers and 12 minutes.

Answer: d

Step-by-step explanation:

The domain of the function that is represented by the graph is: D. x ≥ -7.

The domain of a function are all the possible x-values in a function which are plotted against the y-values on the x-axis.

In the graph given, the x-axis where the line starts from is -7, and it extends to infinity to the right.

Therefore, the domain of the function is: D. x ≥ -7.

Step-by-step explanation:

Given that,

A person walks 12.0 m east, then turns and goes 5.00 m west, then turns and goes back 2.00 m east.

(a) Distance is equal to total path covered during the entire journey.

Distance = 12 + 5 +2

Distance = 19 m

(b) The shortest path covered is equal to the shortest path traveled. Let east is positive and west is negative. So,

Displacement = 12 +(-5) +2

Displacement = 9 m

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Mean score (m) = 80

Standard deviation = 4

Acore within one standard deviation of the mean:

Zscore = ± 1

Using the relation:

Zscore = (x - mean) / standard deviation

Where x = score

±1 = (x - 80) / 4

4 = x - 80

±4 + 80 = x

x = - 4 + 80 = 76

x = 4 + 80 = 84

Scire with 1 standard deviation of the mean :

76 = 1 standard deviation below

84 = 1 standard deviation above

Answer:

B

Step-by-step explanation:

A graph is only a function when there is only one y value for each x value.

A trick is to draw a line through some points on the x-axis, and if the line goes through more than one point. Then it is not a function. (See picture)

Sorry, not all the lines are straight, but you get the point. B is the only one that doesn't have more than one point on the lines I drew.

Answer:

[tex]x\neq 1+2n,n\in\mathbb{Z}[/tex]

Step-by-step explanation:

Remember that for the tangent parent function, it has infinite discontinuities (vertical asymptotes) on:

[tex]f(x)=\tan(x), \\\text{Where }x\neq\frac{\pi}{2}+n\pi, n\in\mathbb{Z}[/tex]

Here, we have:

[tex]f(x)=\tan(\frac{\pi x}{2})[/tex]

So, we can set the expression inside the tangent to equal our parent domain restriction. This yields:

[tex]\frac{\pi x}{2}\neq\frac{\pi}{2}+n\pi[/tex]

Solve for x. Multiply both sides by 2:

[tex]\pi x\neq \pi+2n\pi[/tex]

Divide both sides by π:

[tex]x\neq 1+2n, n\in\mathbb{Z}[/tex]

Therefore, for the function [tex]f(x)=\tan(\frac{\pi x}{2})[/tex], it is not continuous for all Xs [tex]1+2n[/tex] where [tex]n\in\mathbb{Z}[/tex]

Step-by-step explanation:

Given the following :

40 metres covered in 6 seconds

Max speed attained after 6seconds

75 meters covered after 11 seconds

Average Speed for first 40 meters :

Speed = distance / time

Speed = 40m / 6s

Speed = 6.67m/s

To obtain the maximum speed :

Next (75 - 40) meters = 35 meters was covered in (11 - 6)seconds = 5 seconds

Speed at this point is maximum :

Hence, maximum speed = (35m / 5s) = 7m/s

Suppose, Manuel runs for an additional z seconds after reaching max speed :

Distance from starting line 6+z seconds after race started?

Distance after 6 seconds = 40 metres

Distance after z seconds = 7 * z

Total distance = (40 + 7z)

What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?

Distance for first 6 seconds = 40 meters + distance covered after 6 seconds = (7 * (x-6))

40 + 7(x - 6)

Step-by-step explanation:

Mean is an essential concept in mathematics and statistics. The mean is the average or the most common value in a collection of numbers.

How to calculate mean?

There are different ways of measuring the central tendency of a set of values. There are multiple ways to calculate the mean.

Arithmetic mean is the total of the sum of all values in a collection of numbers divided by the number of numbers in a collection. It is calculated in the following way:

Step-by-step explanation:

x² + (y − 1)² = 9

This is a circle with center (0, 1) and radius 3.  We can parameterize it using sine and cosine.

Use the starting point to determine which should be sine and which should be cosine.

Use the direction to determine the signs.

Use the number of revolutions and the interval to determine coefficient of t.

(A) Once around clockwise, starting at (3, 1).  0 ≤ t ≤ 2π.

The particle starts at (3, 1), which is 0 radians on a unit circle.  It makes 1 revolution (2π radians).  Therefore:

x = 3 cos t

y = 1 − 3 sin t

(B) Two times around counterclockwise, starting at (3, 1).  0 ≤ t ≤ 4π.

The particle starts at (3, 1), which is 0 radians on a unit circle.  It makes 2 revolutions (4π radians).  Therefore:

x = 3 cos t

y = 1 + 3 sin t

(C) Halfway around counterclockwise, starting at (0, 4). 0 ≤ t ≤ π.

The particle starts at (0, 4), which is π/2 radians on a unit circle.  It makes 1/2 revolution (π radians).  Therefore:

x = -3 sin t

y = 1 + 3 cos t

Answer:

The value of y when x has a value of 9 is 18

Step-by-step explanation:

Functions

The variables x and y are said to have a quadratic relationship. That information is not enough to set up a general equation for both variables.

Furthermore, we know that tripling the value of x causes the value of y to be multiplied by 9. That leads us to establish a proportional equation between them, as follows:

[tex]y=kx^2[/tex]

Where k is an unknown constant.

Let's use the given point (3,2) to find the value of k:

[tex]2=k(3)^2[/tex]

[tex]2=9k[/tex]

Solving for k:

[tex]\displaystyle k=\frac{2}{9}[/tex]

The equation is now:

[tex]\displaystyle y=\frac{2}{9}x^2[/tex]

Now find y when x=9:

[tex]\displaystyle y=\frac{2}{9}(9)^2[/tex]

[tex]\displaystyle y=\frac{2}{9}\cdot 81=18[/tex]

The value of y when x has a value of 9 is 18

I think it will be 3....?

Answer:

mean 5

median 4

mode 3

Step-by-step explanation:

The mean is the average, or add up all the numbers and divide by the number of numbers

(3+5+2+4+3+4+3+5+16)/9

45/9 = 5

The median is the middle number when listed from smallest to largest

2,3,3,3,4,4,5,5,16

Since there are 9 numbers, the middle is the 5th number

2,3,3,3   ,4,     4,5,5,16

The median is 4

The mode is the number that appears most often which is 3 since it appears 3 times

Answer:

a) 0.5 is the probability of students who selected the stated option.

b) =0.8 is the probability of students who choose the stated option.

c) E(x) = P(x) x n

        = [(5) + (8)]x 1/10

       = 13/10

Step-by-step explanation:

Solution:

Number of students assigned to guilty state = 57

Number of students choose stated option = 45

Randomly Selected students =10

a) Find p(x=5)

x is the number in a sample of 10, who choose the stated option.

Sample number p(s) = 10

P(x) = 5

Probability = p(x) / p(s)

                  = 5/ 10

                   =0.5

0.5 is the probability of students who selected the stated option.

(b) Find p(x=8)?

Sample number p(s) = 10

P(x) = 8

Probability = p(x) / p(s)

                  = 8/ 10

                   =0.8 is the probability of students who choose the stated option.

(c) Expected (mean) value of x?

The expected value can be calculated by multiplying the probability of an event by the event's amount of times.

E(x) = P(x) x n

        = [(5) + (8)]x 1/10

       = 13/10
