Answer:

y = 7/2 x -2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

= (-2 -5)/(0-2)

=-7/-2

= 7/2

We know the y intercept is -2 ( The x coordinate is 0)

Using the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

y = 7/2 x -2

Of people who died in the United States in a recent year, 86% were white, 12% were black, and 2% were Asian. (We will ignore the

Marianna [84]

Answer:

To three decimal place = 0.030

Step-by-step explanation:

Let probability of death in white p (WH) = 86%

Let probability of death in black p(B) =12%

Let probability of death in Asian p(A) = 2%

Probability of death caused by diabetes among white will be 2.8% of p (WH) = 0.86 x 0.028 = 0.02408

Probability of death caused by diabetes among black will be 4.4% of p (B) = 0.12 x 0.044 = 0.00528

Probability of death caused by diabetes among Asian will be 3.5% of p (A) = 0.02x 0.035 = 0.0007‬

If a sample is chosen and the cause is diabetes then the probability will be

Probability of death caused by diabetes among white or Probability of death caused by diabetes among black or Probability of death caused by diabetes among Asian

0.02408 +0.00528 +0.0007 = 0.03006

To three decimal place = 0.030

What are the coordinates of the vertices of the figure A'B'C'after the following transformation. (x,y) ---> ( y, -x)

topjm [15]

9514 1404 393

Answer:

A'(4, 4)
B'(4, 2)
C'(1, 2)

Step-by-step explanation:

Using the transformation ...

(x,y) ⇒ (y, -x) . . . . . . rotation 90° CW

we have ...

A(-4, 4) ⇒ A'(4, 4)

B(-2, 4) ⇒ B'(4, 2)

C( -2, 1) ⇒ C'(1, 2)
