Sloan [31]

an = a1 +d(n-1)

a4 =a1+d(4-1)

-4 = -1+d(3)

add 1 to each side

-3 = 3d

d= -1

an = a1 +d(n-1)

an = -1 +-1 (n-1)

an = -1 -n +1

Which of the following describes a ratio of actual events to the number of trials in an experiment? Select all that apply. HELP
aleksklad [387]
Experiental probability is the correct choice because you will have actual data from an experiment that you are using to create the ratio of outcomes to attempts. This is the scientific and mathematical name for a tested ratio. Theoretical probability, on the other hand, is what you would expect to happen if you were to perform the test.

On his drive from Montpelier, Vermont, to Columbia, South Carolina, Arthur averaged 51 mph. If he had been able to average 60 mp
Llana [10]

Answer:

Distance between Montpelier and Columbia is 1020

Step-by-step explanation:

51 mi/hr average:

d = 51 t  

60 mi/hr average:

d t = 60*(t-3)

Substitute (1) into (2)  

   51 t =  60*(t-3)

   51 t =  60 t + 180

   9 t  =  180

   t    =   20

d = 51 t

   = 51 (20)

   = 1020

let see distance is 1020 lets check

51 t = 60 * (t-3)

51 (20)= 60* (20-3)

1020   = 60*17

1020 = 1020

What is the value of x in the problem ?
Elis [28]

Answer:

The x angle is 112 degrees

Step-by-step explanation:

<u>Step 1:  Find the adjacent angle to 134 </u>

134 + w = 180

w + 134 - 134 = 180 - 134

w = 46

<u>Step 2:  Find the last angle inside the triangle </u>

46 + 22 + x = 180

68 + x = 180

x + 68 - 68 = 180 - 68

x = 112

Answer:  The x angle is 112 degrees
