How do you graph y=1/2x-2

1 answer:

1/2 is the slope. Since it’s 1/2x -2, I’m pretty sure it’s negative 2 as your y intercept. So as you do rise/run. You plot -2, and then from that point go up one and over 2. And from that point go up one and over 2. Repeat and if necessary get your slope.. I hope this helped I did this in the beginning of 8th grade.

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

$M = \frac{a+b}{2}$

The standard deviation is:

$S = \sqrt{\frac{(b-a)^{2}}{12}}$

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

$M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5$

Standard deviation:

$S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64$

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Answer:

To graph this on a coordinate plane, you have to go left 10 and down to -3. On 3,2, you go right 3 then up 2.

Answer:

C

Step-by-step explanation:

Since CB is a tangent to the circle then ∠ ABC = 90°

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus

AC² = 5² + 8² = 25 + 64 = 89 ( take the square root of both sides )

AC = $\sqrt{89}$ → C
