Answer:

(x + 1)^2 + (y - 2)^2 = 3^2 = 9

Step-by-step explanation:

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

(x - h)^2 + (y - k)^2 = r^2.

Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is

(x + 1)^2 + (y - 2)^2 = 3^2 = 9.

Andre's equation is in the form ...

  b = kf

The value of k can be found by dividing by f:

  b/f = k

For Priya's recipe, the values are ...

  b/f = k = 3/7.5 = 2/5

Andre's equation is ...

  \boxed{b=\dfrac{2}{5}f}

What are the odds in favor of choosing a person at random who chose juice a?
stealth61 [152]

37:53

Step-by-step explanation:

Step 1 :

Given

Number of people choosing Juice A = 37

Number of people choosing Juice B = 32

Number of people choosing Juice C = 21

We need to find the odds in favor of choosing a person who chooses juice A

Step 2  :

Here the number of success is the number of people choosing juice A = 37

Number of failures is the number of the people not choosing juice A = Number of people choosing juice B + Number of people choosing juice C = 32+21 = 53

Hence the odds in favor of choosing a person who chooses juice A is 37:53

What is the value of x in the diagram below?
Tanzania [10]

Answer:

The answer to your question is: x = 100

Step-by-step explanation:

It's a polygon of 7 sides

The sum of internal angles in a polygon equals 180(n-2), where n = # of sides

                 

            Internal angles = 180(7-2)

                                      = 180(5)

                                     = 900°

      (x + 50) + (x + 50) + (x + 50) + x + x + x + (x + 50) = 900

      4(x + 50) + 3x = 900

      4x + 200 + 3x = 900

      7x = 900 - 200

      7x = 700

      x = 700 / 7

      x = 100
