The y-intercept is (0,2)

  • you can find the y-intercept by finding the value of y when x = 0

The slope is -5/2.

  • you can find the slope by using the equation below and any two points on the line, such as (0,2) and (2,-3)

           \frac{y2-y1}{x2-x1}=\frac{-3-2}{2-0}  =\frac{-5}{2}

               

Hope that helps!

Consider the probability distribution shown below. x 0 1 2 P(x) 0.15 0.80 0.05 Compute the expected value of the distribution. (
larisa [96]

Answer:

Expected value =0.9

Standard deviation = 0.4359

Step-by-step explanation:

Let's use the formula to find expected value or mean.

Expected value =Σ x *P(x)

  x    0    1     2

P(x) ) .15  .8  .05

So, expected value = (0)(0.15) +1(0.8)+2(0.05)

                                = 0 +0.8 +0.1

                                =0.9

Expected value =0.9

Now, let's find standard deviation

x           (x- E(x))^{2}         (x-E(x))^{2} *p(x)

0           (0-0.9)^{2}            (0-0.9)^{2} *0.15  =0.1215

1            (1-0.9)^{2}            (1-0.9)^{2} *0.8    =0.008

2           (2-0.9)^{2}             (2-0.9)^{2} *0.05  =0.0605

Now, add the last column together and then take square root to find standard deviation.

Standard deviation of the distribution =\sqrt{0.1215+0.008+0.0605)}

Simplify it, so standard deviation =0.4358898...

Round the answer to nearest four decimal places

Standard deviation = 0.4359

P(x) = 2x2 + 5x - 9<br> Part A<br> Evaluate p(1.75).
Vladimir79 [104]

Answer:

Hi there!

Your answer is:

p(1.75) = 5.875

Step-by-step explanation:

p(1.75) means to plug in 1.75 for x

p(1.75)= 2(1.75)^2 + 5(1.75) - 9

6.125 + 8.75 - 9

SIMPLIFY

5.875

Hope this helps!
