1) -3x +y = 8

2) -2x + 3y = 1

3)5y +3X = 10

Answers

Answer:

Step-by-step explanation:

1. is y= 3 x +8

-3 x +  y - 8= 0

y = 3x+ 8

2. is in the pictures

3.

3 X + 5 y - 10 = 0

Real solution:

y = 2 - (3 X)/5

Solution:

y = 2 - (3 X)/5

Integer solution:

X = 5 n, y = 2 - 3 n, n element Z

Solution for the variable y:

y = 1/5 (10 - 3 X)

The heights of a large population of ostriches are normally distributed. Which is the closest to the percentage of these heights that is within 3 standard deviations of the mean?

a. 95%
b. 99.7%
c. 0.3%
d. 5%

Answers

It is option B. 99.7 %

The value of 99.7% is the closest to the percentage of these heights that is within 3 standard deviations of the mean.

What is the empirical rule?

If your distribution follows a normal distribution, the standard deviation and mean can tell you where the majority of the data are.

It is given that:

The heights of a large population of ostriches are normally distributed.

The percentage of these heights that is within 3 standard deviations of the mean

As we know from the empirical rule:

It is the rule of 68-95-99.7.

From the data given in the question:

The height of a large population of ostriches is normally distributed.

So,

X ~ (u, б²)

Normal distribution.

P{u - 3б < X < u + 3б}

From the distribution table:

P{u - 3б < X < u + 3б} = 99.7%

Thus, the value of 99.7% is the closest to the percentage of these heights that is within 3 standard deviations of the mean.

B- Max has 10$. He earns 25.75$ for every lawn that he mows.

D is also an answer.

Step-by-step explanation:

This equation is an example of the formula y=mx+b, where mx is the slope and b is the y intercept, the slope is a continuous thing where as the y- intercept is like a beginning point.

So, A is incorrect because it puts 25.75 as the y intercept when it should be the slope. C is wrong because that is not even the kind of equation we are working with, and E is a different equation. I think the only possible answers are B and D

An airplane is flying on a bearing of 330 degrees at 450 mph. Find the component form of the velocity of the airplane.

Answers

Answer:

The component form of the velocity of the airplane is [tex]\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right][/tex].

Step-by-step explanation:

Let suppose that a bearing of 0 degrees corresponds with the [tex]+x[/tex] direction and that angle is measured counterclockwise. Besides, we must know both the magnitude of velocity ([tex]\|\vec v\|[/tex]), in miles per hour, and the direction of the airplane ([tex]\theta[/tex]), in sexagesimal degrees to construct the respective vector. The component form of the velocity of the airplane is equivalent to a vector in rectangular form with physical units, that is:

[tex]\vec v = \|\vec v\|\cdot (\cos \theta \,\hat{i}+\sin \theta\,\hat{j})[/tex] (1)

If we know that [tex]\|\vec v\| = 450\,\frac{mi}{h}[/tex] and [tex]\theta = 330^{\circ}[/tex], then the component form of the velocity of the airplane is:

[tex]\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right][/tex]

The component form of the velocity of the airplane is [tex]\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right][/tex].

What are the center and the radius of the circle 4x2 + 4y2 - 4x + 16y + 1 = 0?

Answers

Answer:

Center of circle: (1, -2)

Radius: √6

Step-by-step explanation:

First, we need to isolate the constant:

Then, we can divide the whole equation by 4:

Then, we can complete the square(reminder: (a+b)^2 = a^2 + 2ab + b^2)

Now that we got the standard equation of the circle, we can find the center and radius by using the equation , where (h, k) is the coordinate of the center, and r is the radius.

Therefore, the center of the circle is (1, -2), and the radius of the circle is √6.

Step-by-step explanation:

The center and radius of the circle 4x² + 4y² - 4x + 16y + 1 = 0 are (1/2, -2) and  2 respectively.

To solve the question, we need to know the standard equation of a circle.

What is the standard equation of a circle?

The standard equation of a circle with center (h,k) and radius, r is

(x - h)² + (y - k)² = r²  (1)

Now, to find the center and radius of 4x² + 4y² - 4x + 16y + 1 = 0, we convert it to standard form by completing the square method.

What is completing the square method?

This is a mathematical operation in which we convert a mathematical expression into a perfect square.

So, 4x² + 4y² - 4x + 16y + 1 = 0

Subtracting 1 from both sides, we have

4x² + 4y² - 4x + 16y + 1 - 1 = 0 - 1

4x² + 4y² - 4x + 16y = - 1

Divding through by 4, we have

x² + y² - x + 4y = -1/4

Adding half the square of the coefficient of x and y to both sides, we have

x² + y² - x + 4y + (-1/2)² + 2² = -1/4 + (-1/2)² + 2²

x² - x + (-1/2)² + y² + 4y + 2² = -1/4 + 1/4 + 2²

(x - 1/2)² + (y + 2)² = 0 + 2²

(x - 1/2)² + (y + 2)² = 2²  (2)

Comparing equations (1) and (2), we have h = 1/2, k = -2 and r = 2.

So, the center and radius of the circle 4x² + 4y² - 4x + 16y + 1 = 0 are (1/2, -2) and  2 respectively.

(1 2 ÷ 3) (2 1 ÷ 2) = x

Step-by-step explanation:

The equation is

Let us assume x be the amount of flour she will need in cups.

Now

1 2 ÷ 3 becomes 5 ÷ 3

2 1 ÷ 3 becomes 5 ÷ 2

Now multiply each number  

(5 ÷ 3)(5 ÷ 2) = x  

25 ÷ 6 = x

Hence, (1 2 ÷ 3) (2 1 ÷ 2) = x this would be the equation

Can anyone find d-bar (the d with the line over it) and explain it to me? For this problem five trials are done at eight am and then twelve am. The eight am trials are 98.4, 98.6, 97.8, 97.1, and 97.5. The 12am ones are 98.9, 99, 97.9, 96.6, and 97.7. The correct answer is -0.14 but I can't get that answer.

Answers

Answer:

d-bar= ∑d/n= -0.7/ 5= -0.14

Step-by-step explanation:

Eight am             12 am             difference (8:00am- 12:00 am)= d

98.4                      98.9              (98.4-98.9=) -0.5

98.6                       99               (98.6-99=) -0.4

97.8                       97.9            (97.8-97.9=) - 0.1

97.1                       96.6             (97.1-96.6=)+0.5

97.5                       97.7              (97.5-97.7=)-0.2        

∑                                                  -0.7        

d= difference between 8 am and 12 am

First we subtract the 12.00 am times from 8:00 am times.

Then we add all the differences to get the total difference ∑d.

∑d= -0.7= total of the difference between two times.

n= number of observations=5

Putting the values in the formula would give the answer.

d-bar= d`= ∑d/n= -0.7/ 5= -0.14
