Answer:

Equation:   y = 65x

Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.

Step-by-step explanation:

Pick any two points to find slope, let's got with (3, 195) and (4, 260):

  slope m = (y₂- y₁) / (x₂ - x₁)

                = (260 - 195) / (4 - 3)

                = 65 / 1

            m = 65

Find y-intercept by using m from above and another point from your table, let's go with (5, 325):

  y = mx + b

  325 = 65(5) + b

  325 = 325 + b

  b = 0

Use m and b to form equation of line:

  y = mx + b

  y = 65x + 0

  y = 65x

Check:

  point (3, 195):   195 = 65(3)       ====>   195 = 195

  point (4, 260):   260 = 65(4)     ====>   260 = 260

  point (5, 325):   325 = 65(5)     ====>   325 = 325

  point (6, 390):   390 = 65(6)     ====>   390 = 390

Example of a point that doesn't belong on table:

  point (8, 500):    500 = 65(8)    ====>   500 ≠ 520

<h2> 5mile per hour</h2>

Step-by-step explanation:

Step one:

given data

distance= 1/4mile

time taken= 1/20 hour

Step two:

Required

speed

we know that speed is

speed= distance/time

substituting

speed= 1/4/1/20

speed=1/4*20/1

speeed=20/4

speed=5mile/hour

The option a sis correct, the speed is 5mile per hour

Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Round your answer to f
Angelina_Jolie [31]

Answer:

P(z>1.51) =1-P(Z

And i fwe look into the normalstandar dtable we can find the desired probability:

P(z>1.51) =1-P(Z

And then the The area to the right of z = 1.51 is 0.0655

Step-by-step explanation:

For this case we want to find the following probability:

P(z>1.51)

And for this case we can use the normal standard distribution and the complement rule and we have this:

P(z>1.51) =1-P(Z

And i fwe look into the normalstandar dtable we can find the desired probability:

P(z>1.51) =1-P(Z

And then the The area to the right of z = 1.51 is 0.0655
