Answer:

Step-by-step explanation:

You need to use a calculator.

It is however useful to remember some values for tangents.

For example tan  45 degrees = 1.

Tan 30 =  1 /√3  and tan 60 = √3.

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

\dfrac{x}{8000}=\dfrac{3}{125}

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

x=\dfrac{3}{125}(8000)

x=0.024(8000)

x=192

So around 192 cell phones are expected to be defective out of 8000 phones.

Answer:

 y = -1/3x + 3 2/3

Step-by-step explanation:

step 1. find the slope of the given line

y2-y1/x2-x1          2 - 4/ 3 + 3 = - 1 / 3

take the opposite of that and there is your slope

step 2. plug in the values to the following equation using the given point:

y - y1 = m ( x - x1 )          y - 4 = - 1/3 ( x + 1 )

step 3. solve for y

y-4 = -1/3(x+1)

-1/3(x) and -1/3(1)  ----> y-4 = -1/3x-1/3

y-4+4 = -1/3x-1/3+4  ---->  y = -1/3x + 3 2/3
