Answer:

y=1/3x

Step-by-step explanation:

Find the slope:  <u>2-(-1)</u>

                          6-(-3)

slope = 1/3

Point Slope Form: y-2= 1/3 (x-6)  <em>plug one of the coordinates into the equation</em>

                              y-2= 1/3x -2

                                  y=1/3x

Answer:

The probability it will land on green every time is \frac{1}{27}.

Step-by-step explanation:

We are given that a spinner is used for which it is equally probable that the pointer will land on any one of six regions. Three of the regions are colored red, two are colored green, and one is colored yellow.

The pointer is spun three times.

<u>As we know that the probability of an event is described as;</u>

  Probability of an event =  \frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}

Here, the favorable outcome is that the spinner will land on green every time.

So, the number of green regions = 2

Total number of regions = 3(red) + 2(green) + 1(yellow) = 6 regions

<em>Now, the probability it will land on green every time is given by;</em>

        Probability =  \frac{2}{6}\times \frac{2}{6}\times \frac{2}{6}

                           =  \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}

                           =  \frac{1}{27}

Hence, the probability it will land on green every time is \frac{1}{27}.

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days). Assume that the number o
UNO [17]

The equation is given as

y = 12 sin (6t - \pi /2) + 2

<h3>The Amplitude </h3>

The Amplitude can be calculated as

amplitude = \frac{max + min}{2}\\ amplitude = \frac{10+14}{2} = 12

<h3>The Vertical Shift</h3>

The vertical shift is the average difference between the maximum and minimum.

Vertical Shift = \frac{Max - Min}{2} = \frac{14-10}{2} = 2

For b value

The Time Period will be twice the distance between max and min.

time period = \frac{2\pi }{b} \\time period = 2 * distance between max and min\\b = \frac{2\pi }{2}*\frac{1}{b} = \frac{\pi }{6}

<h3>The Period</h3>

The period is calculated as

T = \frac{2\pi }{b} \\T = \frac{2\pi }{\frac{\pi }{b} } = 12

The equation is given as

y = 12 sin (6t - \pi /2) + 2
