ANSWER:the size of reflex angle is

C:314 degrees

Answer:

Step-by-step explanation:

Plot any tow points on the line and find the slope

(-1 , 3)  ; ( -2 , 1)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

         [tex]= \frac{1-3}{-2-[-1]}\\\\= \frac{-2}{-2+1}\\\\=\frac{-2}{-1}\\\\=2[/tex]

m = 2 ; (-1 , 3)

 y - y1 = m(x - x1)

y - 3 = 2*(x - [-1])

y - 3 = 2*(x + 1)

y -3 = 2*x + 2*1

y -3 = 2x + 2

   y = 2x + 2 + 3

  y = 2x + 5

Slope = 2

y-intercept = 5

The solution is 4 green

The probability of choosing a green counter from the bag is 0.2

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

Let the probability of choosing a green counter be = P

Now , the value of P is

Let the total number of blue counters be G = 2

Let the total number of green counters be G = 4

Let the total number of red counters be G = 5

Let the total number of yellow counters be G = 9

So , the total number of counters = number of blue counters + number of green counters + number of red counters + number of yellow counters

Substituting the values in the equation , we get

The total number of counters = 2 + 4 + 5 + 9

The total number of counters = 20

Now , the probability of choosing the green counter P = total number of green counters / total number of counters

Substituting the values in the equation , we get

Probability of choosing the green counter P = 4/20

Probability of choosing the green counter P = 2/10

Probability of choosing the green counter P = 0.2

Therefore , the value of P is 0.2

Hence , the probability of choosing green counter is 0.2

Answer:

Gets Smaller

If her model is valid, she expect from the total data collected after three months that the difference between the data and the model will get smaller. The correct option is A.

When some amount of money is used to buy the share of a particular company, then the percentage of total sales generated by that company is called the market share.

A financial analyst collects data over the next month to evaluate her model. At the end of the month, she finds that for one of the companies, the difference between her model and the data is 5%. She decides to collect data for an additional two months.

If the model is valid, then she can assume that her assumptions are correct over the model according to the data. It will result in decreasing the bridge gap between the model and the collected data.

Therefore, If her model is valid, she expect from the total data collected after three months that the difference between the data and the model will get smaller. The correct option is A.

what is the question? please provide a question.

The factorization of the given trinomial [tex]x^2 - 9x+ 20[/tex] is (x – 4)(x - 5). The correct option is A.

A trinomial is a polynomial that has three terms. To factor a trinomial of the form [tex]ax^2 + bx + c[/tex], you need to find two binomials that multiply together to produce the original trinomial.

To factor the trinomial [tex]x^2 - 9x + 20[/tex], we need to find two numbers that multiply to 20 and add up to -9. These two numbers are -4 and -5. Therefore, we can write:

[tex]x^2 - 9x + 20 = (x - 4)(x - 5)[/tex]

Or, To factor [tex]x^2 - 9x + 20[/tex], you need to find two numbers that multiply to 20 and add up to -9. These numbers are -4 and -5 because -4*(-5) = 20 and -4 + (-5) = -9.

You can factor the trinomial as (x - 4)(x - 5).

Thus, the correct option is A.
