He would change his tires a total of 4 times.
You divide the numbers like so:
160,000/40,000=4
Answer:
z = 55.15432893
x = 59.61543424
y = 22.5166605
Step-by-step explanation:
To find length "z" you will have to use SOHCAHTOA.
Labelling the triangle will show us that the side marked "z" is the hyp and the side marked 39 is the opp.
sin 45 = 
z sin 45 = 39
z = 
z = 55.15432893
Using Pythagoras' theorem, you can find that the adj = 39
In the other triangles POV, the adj is actually the opp.
Therefore, use tangent to find y.
tan 60 = 
y tan 60 = 39
y = 
y = 22.5166605
Use Pythagoras's Theorem to find x.

Answer:
C.
Step-by-step explanation:
The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
mean of total = 7+7+7+7 = 28
Variance of total = 4+4+4+4 = 16
SD of total = sqrt(16) = 4
For this case we have a function of the form:

Where,
m: slope of the line
b: cutting point with the y axis.
The line cuts to the y-axis at the point:

Therefore, the value of b is given by:

We now look for the slope of the line.
For this, we use the following equation:

Substituting values we have:

Rewriting:

Then, the equation of the line is:

Answer:
the rule that matches the function shown in the graph is:
