Energy is measured in kilowatt-hours. The table and scatter plot below, show the cost of building a facility to produce energy a

nd the ongoing cost of operating the facility for five different types of energy.Do you think that there is a statistical relationship between building cost and operating cost? if so, describe the nature of the relationship.

Yes, because it looks like there is a downward pattern in the scatter plot. It appears that the types of energy that have facilities that are more expensive to build are less expensive to operate.

I need help...............
Viefleur [7K]

Answer:

$7

Step-by-step explanation:

You can see that it "rises" 700 and "runs" 100, that means that there is a slope of 700/100. If you simplify that, it turn out to be a slope of 7. Meaning that each ticket costs $7. Hope this helps, let me know if you need a better explanation!

Triangle X Y Z is translated up 2 and right 3 units to form triangle C A B. Triangle XYZ was translated up 2 and right 3 units,
nata0808 [166]

Answer:

YZ ≅ AB

Step-by-step explanation:

A translation is a correspondence between two mathematical figures, for instance, the coordinates of each point in a straight line of one figure that is added to the coordinates of the corresponding point on the other figure.

But here, we are given a Δ XYZ which is translated to ΔCAB. This tells us more about how the corresponding points preserve their congruence nature.

i.e.

X corresponds to C

Y  corresponds to A

Z  corresponds to B

Similarly;

XY  corresponds to CA

YZ  corresponds to AB

XZ  corresponds to CB

Since both triangles preserve their congruence nature, then all corresponding points are congruent as well.

Therefore, from the choice of options given, only YZ  corresponds to AB is the right answer.

i.e.

YZ ≅ AB

Three students can wash a car in 16 minutes. If the varies inversely with the number of students washing the car, how many minut
aleksley [76]

Answer:

Two students will take 24 minutes to wash the car.

Step-by-step explanation:

In this case we can apply a rule of three to find out the time that will take for the students to wash the car. This has to be done such as:

3 students -> 16 minutes

2 students -> x minutes

3/2 = 16/x

But in this cases the problem states that this variables are inversely proportionate, which means that if there's less students washing the car they will take more time to finish the job. So we need to invert one of the fractions before computing the result.

3/2 = x/16

2*x = 3*16

x = 48/2 = 24 minutes.

Two students will take 24 minutes to wash the car.
