Kevin installed a certain brand of automatic garage door opener that utilizes a transmitter control with five independent​ switc

hes, each one on or off. The receiver​ (wired to the​ door) must be set with the same pattern as the transmitter. If one of​ Kevin's neighbors also has this same brand of​ opener, and both of them set the switches​ randomly, what is the probability that they will use the same​ setting?

Answer:

0.03125

Step-by-step explanation:

Number of Combinations possible with the Transmitters = 2*2*2*2*2 = 32

Probability that they will use the same settings = 1 - Probability of them using different settings.

= 1 - 32*31/(32^2)

=1 - 992/1024

= 1 - 0.96875

= 0.03125

Answer:

SteAnswer:

y = 1/2x + 3/2

Step-by-step explanation:

Using the equation of the line

y - y_1 = m ( x - x_1)

First find the slope of the line

-2x + 4y = 8

It must be in this form

y = mx + C

4y = 8 + 2x

divide through by 4

4y/4 = 8 + 2x / 4

y = 8 + 2x/4

Let's separate

y = 8/4 + 2x/4

y = 2 + 1/2x

y = 1/2x + 2

Therefore, our slope or m is 1/2

Using the equation of the line

y - y_1 = m ( x - x_1)

With point (-5, -1)

x_1 = -5

y_1 = -1

y - (-1) = 1/2(x - (-5)

y + 1 = 1/2( x + 5)

Opening the brackets

y + 1 = x + 5 / 2

y = x + 5/2 - 1

Lcm is 2

y = x + 5 / 2 - 1/1

y = x + 5 -2/2

y = x +3/2

We can still separate it

y = x /2 + 3/2

y = 1/2x + 3/2

The equation of the line is

y = 1/2x + 3/2

The correct answer is A

Cylinders are 3D figures, as they are solids with volume and take up space.

2D figures are flat figures that you can draw, like a square or circle.

1D figures are actually just a line, a segment, or a point, etc.

Buyers are skeptical of a motorcycle advertisement that claims the newest model gets an average of 52 miles per gallon. They bel
Lana71 [14]

Answer:

Null hypothesis; H0: µ ≥ 52 mpg

Alternative hypothesis; Ha: µ < 52 mpg

Step-by-step explanation:

We are told that the newest model gets an average of 52 miles per gallon and that the buyers believe that the average mpg was overstated.

This means the alternative hypothesis will have an average less than 52. Thus;

Null hypothesis; H0: µ ≥ 52 mpg

Alternative hypothesis; Ha: µ < 52 mpg

Write an equation in slope-intercept form of the line with slope 3 that contains the point (1,2). HELP PLEASE!!
Andrej [43]

point slope form = y-y1 = m(x-x1)

y-2 = 3(x-1)

distribute

y-2 = 3x-3

add 2 to each side

y = 3x-1

this is in slope intercept form

UkoKoshka [18]
Total miles= rate x time

We can set up 2 eq:
24=(x+8)(y-4)
24=xy

Where x is equal to my original rate
and y is equal to the original time spent traveling the 2mi

We can now solve for one of the variables and find our rate
