The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

To simulate an event that has a probability of success of 20%, we need to randomly generate numbers from 0 to 9 such that there is a 20% chance of getting a "success" number.

Since there are 10 possible numbers to choose from, 20% of them would be 2 "success" numbers.

So, any group of numbers that contains two "success" numbers out of 10 would represent a success.

For example,

The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

Other groups with two "success" numbers would also be valid.

Thus,

The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

Hello there.

First, assume the numbers [tex]x,~y[/tex] such that they satisties both affirmations:

With these informations, we can set the following equations:

[tex]\begin{center}\align x^2+y^2=8\\ x\cdot y=4\\\end{center}[/tex]

Multiply both sides of the second equation by a factor of [tex]2[/tex]:

[tex]2\cdot x\cdot y = 2\cdot 4\\\\\\ 2xy=8~~~~~(2)^{\ast}[/tex]

Make [tex](1)-(2)^{\ast}[/tex]

[tex]x^2+y^2-2xy=8-8\\\\\\ x^2-2xy+y^2=0[/tex]

We can rewrite the expression on the left hand side using the binomial expansion in reverse: [tex](a-b)^2=a^2-2ab+b^2[/tex], such that:

[tex](x-y)^2=0[/tex]

The square of a number is equal to [tex]0[/tex] if and only if such number is equal to [tex]0[/tex], thus:

[tex]x-y=0\\\\\\ x=y~~~~~~(3)[/tex]

Substituting that information from [tex](3)[/tex] in [tex](2)[/tex], we get:

[tex]x\cdot x = 4\\\\\\ x^2=4[/tex]

Calculate the square root on both sides of the equation:

[tex]\sqrt{x^2}=\sqrt{4}\\\\\\ |x|=2\\\\\\ x=\pm~2[/tex]

Once again with the information in [tex](3)[/tex], we have that:

[tex]y=\pm~2[/tex]

The set of solutions of that satisfies both affirmations is:

[tex]S=\{(x,~y)\in\mathbb{R}^2~|~(x,~y)=(-2,\,-2),~(2,~2)\}[/tex]

This is the set we were looking for.

Answer:

He planted 60 tomato plants, or 5 dozen tomato plants.

Step-by-step explanation:

6 dozen = 6 × 12 = 72

He planted 72 plants and harvested 104 tomatoes per plant.

The next year he had a crop of 6,240 tomatoes, and also got 104 tomatoes per plant.

6,240/104 = 60

He planted 60 tomato plants, or 5 dozen tomato plants.

Answer:

12$/D

Step-by-step explanation: 20% of 10 = 2

he spends 10 so -10 then sells for 120% of that which is 12

so, 10+2= 12

Answer:

  MN = 56

Step-by-step explanation:

This can only be solved if we know the relation of MN to other dimensions of the trapezoid. If we assume MN is a midline (AM=MD, BN=NC), then MN is the average of the base lengths:

  MN = (AB +CD)/2

  2MN = AB +CD . . . . . multiply by 2

  2(12x -4) = 8x +72 . . . fill in the given values for the segment lengths

  24x -8 = 8x +72 . . . . . eliminate parentheses

  16x = 80 . . . . . . . . . . . add 8-8x

  x = 5 . . . . . . . . . . . . . . divide by 16

  MN = 12(5) -4 = 56 . . . find the length of MN using its formula

Find the total number of people

Total = those voting + those not voting

Total = 42 + 58

Total = 100

Find the % voting

% = voting * 100/ total = 42 * 100 / 100 = 42%

The rate of change of the crop's seed production is given by differential of

the function of the number of seeds produced.

Reasons:

[tex]\displaystyle \mathrm{The \ number \ of \ seeds \ per \ plant, \ S(t)}= \mathbf{\frac{t^2}{4}}[/tex]

[tex]\displaystyle \mathrm{Plants \ that \ mature \ to \ age \ t, \ P(t)}= \mathbf{40.56- \frac{t^2}{4} + \frac{1,801.75}{t^2} +\frac{188.8}{t}}[/tex]

The number of seeds produced by all the plants, n = S(t) × P(t)

Which gives;

[tex]\displaystyle \mathrm{\ P(t) \times S(t)}= \left(40.56- \frac{t^2}{4} + \frac{1,801.75}{t^2} +\frac{188.8}{t}\right) \times \frac{t^2}{4}[/tex]

[tex]\displaystyle \mathrm{ \left(40.56- \frac{t^2}{4} + \frac{1801.75}{t^2} +\frac{188.8}{t}\right) \cdot\frac{t^2}{4}} = \mathbf{-0.0625\cdot t^4+10.14\cdot t^2 + 47.2 \cdot t + 450.4375}[/tex]

The maximum rate of change is the highest value of the rate of change function.

To find the maximum rate of change of the crops production, the above

function for the number of seeds is differentiated twice. The first

differentiation is to find the rate of change function, and the second

differentiation is to determine the value of t at the maximum rate of change

as follows;

The rate of change of the crop's seed production is given by following function;

[tex]\displaystyle \frac{d}{dt} \left( -0.0625\cdot t^4+10.14\cdot t^2 + 47.2 \cdot t + 450.4375 \right) = -0.25\cdot t^3+ 20.28 \cdot t - 47.2[/tex]

Rate of change function, n'(t) = -0.25·t³ + 20.28·t + 47.2

At the maximum value of the above rate of change function, we have

[tex]\displaystyle \frac{d}{dt} \left( -0.25\cdot t^3+ 20.28 \cdot t - 47.2 \right) = \mathbf{-0.75 \cdot t^2 + 20.28} = 0[/tex]

Which gives

[tex]\displaystyle t^2 = \frac{20.28}{0.75} = \mathbf{27.04}[/tex]

t = √27.04 = 5.2

At the maximum rate of change, the number of weeks, t = 5.2

Plugging in the value of  t = 5.2 into the rate of change function gives;

n'(5.2) = -0.25·5.2³ + 20.28·5.2 + 47.2 = 117.504
