what is the slope of the line that contains these points x=12,13,14,15 y=-4,2,8,14

Answers

Answer 1

Answer:

6

Step-by-step explanation:

Fid the difference in the y-coordinates of any two points. This is the rise.

Then find the difference in the corresponding x-coordinates of the same points. This is the run.

slope = rise/run

Let's use x = 12, x = 15, and y = -4, y = 14.

rise = -4 - 14 = -18

run = 12 - 15 = -3

slope = rise/run = -18/(-3) = 6

Answer: slope = 6

Answers

Answer:

a

 [tex]E(Z) =  202 [/tex]  

b

[tex]E(Z) = 198[/tex]

c

[tex]E(Z) = -140  [/tex]

Step-by-step explanation:

From the question we are told that

   The mean of X  is [tex] E(X)  =  20[/tex]

   The standard deviation of X is  [tex]s_1 = 5[/tex]

   The mean of Y  is [tex]\= y  =  40[/tex]

    The standard deviation of Y is  [tex]s_2 = 10[/tex]

Considering question a  

Generally the mean of   Z = 2 + 10X. is mathematically  represented

    [tex]E(Z) = E[2 + 10X ][/tex]

=> [tex]E(Z) =  2 +  10 E(X)[/tex]

=>  [tex]E(Z) =  2 +  10 * 20 [/tex]        

=>  [tex]E(Z) =  202 [/tex]          

Considering question b

Generally the mean of   Z = 10X - 2.. is mathematically  represented  

        [tex]E(Z) = E[10X -2 ][/tex]

   => [tex]E(Z) = 10E(X) - 2[/tex]

  =>  [tex]E(Z) = 10* 20  - 2[/tex]

  =>  [tex]E(Z) = 200  - 2[/tex]

 =>  [tex]E(Z) = 198[/tex]

Considering question c

Generally the mean of   -3X - 2Y is mathematically  represented

     [tex]E(Z) = E[-3X -2Y ][/tex]

     [tex]E(Z) = -3 E(X) -2E(Y) [/tex]

=>   [tex]E(Z) = -3 * 20 -2* 40 [/tex]

=> [tex]E(Z) = -140  [/tex]

g What is the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty?

Answers

Answer:

16

Step-by-step explanation:

In order to get the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty, we need to calculate the power of the set having four elements. Let the set containing the element be A as shown;

Let set A = {a, b, c, d}

Power of the set P(A) = [tex]2^n[/tex] where:

n is the total number of element in the set. Since we have four elements in the set, n = 4

[tex]P(A) = 2^4\\P(A) = 16[/tex]

This means that the set A have 16 subsets. The subsets of the set are:

{}, {a}, {b}, {c}, {d}, {a, b}, {a, c}, {a, d}, {b, c}, {b, d}, {c, d}, {a, b, c}, {a, b, d}, {b, c, d}. {a, c, d}, {a, b, c, d}.

From all the subsets, it can be seen that intersection of set {a} and {b}, {a} and {c}, {c} and {d} are empty.

Hence the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty is 16

+3x−96, x, squared, plus, 3, x, minus, 9.

Your answer should be a polynomial in standard form.

Answers

Answer:

8x²- x -8

Step-by-step explanation:

The question is not well written. I guess what you mean is:

Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).

To  subtract -2x^2+4x-1 from 6x^2+3x-9, that is

6x^2+3x-9 - (-2x^2+4x-1). This can be written as

6x²+3x-9 - (-2x²+4x-1)

Now, opening the bracket, we will get

6x²+3x-9 +2x²-4x+1

Then, collecting like terms, we get

6x²+2x²+3x-4x-9+1

6x²+2x² = 8x²

3x-4x = -x

-9+1 = -8

∴6x²+2x²+3x-4x-9+1 becomes

8x²-x -8

The answer is 8x²-x -8.

Simplified form of the polynomial :

8x²- x -8

Given(correct form of question):

Subtract -2x²+4x-1 ( minus 2x squared plus 4x minus 1) from 6x²+3x-9 (6x squared plus 3x minus 9).

Now,

To  subtract -2x²+4x-1 from 6x²+3x-9, that is

6x²+3x-9 - (-2x²+4x-1). This can be written as

6x²+3x-9 - (-2x²+4x-1)

Now, opening the bracket, we will get

6x²+3x-9 +2x²-4x+1

Then, collecting like terms, we get

6x²+2x²+3x-4x-9+1

6x²+2x² = 8x²

3x-4x = -x

-9+1 = -8

∴6x²+2x²+3x-4x-9+1 becomes 8x²-x -8

Thus,

The answer is 8x²-x -8.

Answers

Answer:

[tex]Probability = \frac{1}{24}[/tex]

Step-by-step explanation:

Given

[tex]Oranges = 3[/tex]

[tex]Apples = 5[/tex]

[tex]Banana = 2[/tex]

[tex]Total = 10[/tex]

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

[tex]Probability = P(Orange) * P(Apple) * P(Banana)[/tex]

[tex]Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}[/tex]

The difference in the numerator is as a result of picking the fruit without replacement

[tex]Probability = \frac{30}{720}[/tex]

[tex]Probability = \frac{1}{24}[/tex]

Probability is simply how likely something is to happen.

The probability of 1 orange, 1 apple, and 1 banana are  [tex]\frac{1}{24}[/tex]

On lunch counter,

Number of oranges = 3

Number of apples = 5

Number of bananas = 2

If 3 piece of fruit is selected then, probability of 1 orange, 1 apple and 1 banana

                          [tex]=\frac{3}{10}*\frac{5}{9} *\frac{2}{8} \\\\=\frac{30}{720}\\\\=\frac{1}{24}[/tex]

Ronald has a 10% solution of the fertilizer Super Grow. How much pure Super Grow should he add to the mixture to get 36 oz of a 12.5% concentration?

Answers

Answer:

1 oz

Step-by-step explanation:

Given that:

% solution of super grow fertilizer = 10%

To obtain mixture of 36oz of a 12.5% concentration

Let oz of pure supergrowth to be added = s

(Initial % * (36 - s) + s) / 36 = target concentration

(10% * (36 - s) + s) / 36 = 12.5%

(0.1(36 - s) + s) / 36 = 0.125

Cross multiply:

0.1(36 - s) + s =. 0.125 * 36

3.6 - 0.1s + s = 4.5

3.6 + 0.9s = 4.5

0.9s = 4.5 - 3.6

0.9s = 0.9

s =. 0.9/0.9

s = 1

Hence, 1 oz of pure supergrowth should be added to the 10% solution to get 36 oz of a 12.5% concentration.

The terminal side of angle θ intersects the unit circle in the first quadrant at (925,y). What are the exact values of sinθ and cosθ?

Answers

Correct question is;

The terminal side of angle θ intersects the unit circle in the first quadrant at (9/25,y). What are the exact values of sinθ and cosθ?

Answer:

sinθ = (√544)/25) and cosθ = 9/25

Step-by-step explanation:

We are given that (9/25,y) lies on the unit circle. Thus, from general representation of equation of a circle, we can write that;

(9/25)² + y² = 1²

y² = 1 - (9/25)²

y² = (625 - 81)/25²

y² = 544/25²

y = ±(√544)/25

We are told the point is in the first quadrant and so we will choose the positive value of y = (√544)/25.

Therefore, the terminal side of the angle θ intersects the unit circle at [9/25, (√544)/25)]

In unit circle geometry, cosθ = x, while sinθ = y.

Thus; sinθ = (√544)/25) and cosθ = 9/25

The exact value of [tex]sin\theta[/tex] and [tex]cos\theta[/tex] is  [tex]cos\theta = \frac{9}{25} , sin\theta = \frac{\sqrt{544} }{25}[/tex] and this can be determined by forming the equation of circle.

Given :

The terminal side of angle [tex]\theta[/tex] intersect at unit circle ([tex]\frac{9}{25}, y[/tex]).

From general representation of equation of circle , we can write

[tex]x^{2} + y^{2} = a^{2}\\[/tex]

[tex](\frac{9^{2} }{25^{2} })[/tex] + [tex]y^{2} = 1^{2}[/tex]

[tex]y^{2} = 1 - \frac{81}{625}[/tex]

[tex]y^{2} = \frac{625-81}{625}[/tex]

[tex]y^{2}=\frac{544}{625}[/tex]

Taking square root both sides

[tex]y= \frac{\sqrt{544} }{\sqrt{625} }[/tex]

[tex]y = \frac{\sqrt{544} }{25}[/tex]

We are taking only because point  lies in first quadrant.

The terminal side of angel [tex]\theta[/tex] unit circle in first quadrant at [tex](\frac{9}{25} , \frac{\sqrt{544} }{25})[/tex]

In unit circle

Rational numbers are those numbers that can be used to express the ratio of two whole numbers. An example is the figure 2. It can be expressed as a fraction of another number like when we write 2/8. Both figures are rational. Irrational numbers cannot be used to express the ratio of two whole numbers or integers. An example is a digit like 0.666666... Rational and irrational numbers are real numbers because real numbers encompass all the types of numbers we can think of, positive, negative, decimals, whole, etc.

The length of a rectangle is three times its width.
If the perimeter of the rectangle is 56 yd, find its area.

Answers

Answer:

147 yards

Step-by-step explanation:

Use a system of equations

Let x be length of rectangle and y be width of rectangle

x = 3y

2x + 2y = 56

Substitute x = 3y into second equation, we have 2(3y) + 2y = 56. Combine like terms and we have 8y = 56. y = 7.

Substituting y = 7 into the first equation, we have x = 3(7), and x = 21.

Area is length times width, so area is 21 * 7 = 147

Answer:

area= 147 yd

Step-by-step explanation:

l= 21 yd

w= 7 yd

Formula: a=lxw (area=length x width)

a=21 x 7

21 x 7=147 yd

Answers

Answer:

From the information given, you can write the following system of equations:

x+y+z=16 (1)

5x+4.5y+5.5z=82 (2)

z=x+y (3)

You can replace (3) in (1) and (2):

x+y+x+y=16

2x+2y=16 (4)

5x+4.5y+5.5(x+y)=82

5x+4.5y+5.5x+5.5y=82

10.5x+10y=82 (5)

Now, you have the following equations:

2x+2y=16 (4)

10.5x+10y=82 (5)

You can isolate x in (4):

2x=16-2y

x=8-y (6)

Then, you have to replace (6) in (5):

10.5(8-y)+10y=82

84-10.5y+10y=82

84-82=10.5y-10y

2=0.5y

y=2/0.5

y=4

Now, you can replace the value of y in (6) to find x:

x=8-4

x=4

Finally, you can replace the vaue of x and y in (3) to find z:

z=4+4

z=8
