1. Geoff rode his bike along an 8-mile path and lost his cell phone at some random location
Elina [12.6K]

Answer:

0.3125

Step-by-step explanation:

Use definition of geometric probability:

P=\dfrac{\text{Desired Length}}{\text{Total Length}}

In your case,

Total Length = 8 miles

Desired Length = 7 - 4.5 = 2.5 miles,

so the probability is

P=\dfrac{2.5}{8}=\dfrac{25}{80}=\dfrac{5}{16}=0.3125

What is the slope of the line l described by the equation below? y=-2x+4
Masteriza [31]

Answer:

The slope of the line would be -2.

Step-by-step explanation:

Because the equation is a line, the slope is the same throughout the entire graph on the equation.

Lets let f(x)=y=-2x+4.

f(0) = -2(0) + 4 = 4

f(0)=4

f(1) = -2(1) + 4 = 2

f(1)=2

Use the equation to find slope.

m(slope) = \frac{2-4}{1-0} = \frac{-2}{1} = -2

<em>The slope would be -2.</em>

<em />

Or:

Use the equation y = mx + b where m=slope.

In the equation y=-2x+4, m=-2.

<em>The slope is -2.</em>
