Answer:

y-4 = 3(x-1)

Step-by-step explanation:

First you will need to find the slope of the two points.

You can do this by using the slope formula:

m=(y_{2}-y_{1} ) /(x_{2}-x_{1})

Which would equal :

\frac{7-4}{2-1} =\frac{3}{1} =3

You would also have to know what point-slope form is:

y-y_{1}=m\left(x-x_{1}\right)

Now insert your points, and the slope.

y-4 = 3(x-1)

Rework problem 7 from section 3.4 of your text, involving the selection of a colored ball from one of three bowls. Assume that y
allochka39001 [22]

Answer:

  • Question (1): 1/2 = 0.5

  • Question (2): 1/6 ≈ 0. 17

Explanation:

<u>1. Arrange the information of the balls contained in the bowls in a table:</u>

                       Bowl X      Bowl Y       Bowl Z     Total

Red balls              2               2                1               5

White balls           2                1                3              6

Blue balls             3                1                2              6

                           ==============================

Totals                     7                4              6             17  

<u>2. To answer each question use the basic definition of probabilities</u>

  • Probability = # of favorable events / # of possible events

<u>3. Question (1) If the ball is blue, what is the probability that it was drawn from bowl X? </u>

<u />

  • Number of total blue balls: 6
  • Number of blue balls in the bowl X: 3
  • Probability that a ball that is blue was drawn from the bowl X: P (b/X)

       P (b/X) = number of blue balls in the bowl X / total number of blue balls = 3 / 6 = 1/2 = 0.5

       

<u>4. Question (2) If the ball is either blue or white, what is the probability that it was drawn from bowl Y?</u>

  • Number of total blue and white balls: 6 + 6 = 12
  • Number of blue balls and white balls in the bowl Y: 1 + 1 = 2
  • Probability that a ball that is either blue or white was drawn from the bowl Y: P (b or w / Y)

       P (b or w /Y) = number of blue balls and white balls in the bowl Y / total number of blue balls and white balls = 2 / 12 = 1/6 ≈ 0.17

10x+2y=10 in slope intercept form
faust18 [17]
 <span>Slope-intercept form is Y = MX + B. This is in standard form, AX + BY = C. You have to move the X to the other side of the equation and simplify it. </span>
<span>10x - 2y = 10 </span>
<span>- 10x - 10x Subtract 10x from both sides </span>
<span>- 2y = - 10x + 10 Now everything is in the right place, but it still needs to be simplified. </span>
<span>Divide each term by -2, in order to isolate the variable Y. </span>
<span>- 2y/ - 2 = - 10x/ - 2 + 10/ - 2 </span>
<span>The answer is: y = 5x - 5</span>
