Answer:

1. D

2. D

3. B

Step-by-step explanation:

1. The y-axis of the graph is the volume of gas in the tank and the x-axis is the distance traveled. So the y-intercept represents how much gas is in the tank before it has been driven anywhere. D

2. Just by inspecting the graph, we can see that the x-intercept is 240. So answers a and c are denitely incorrect. Also, since we know the graph is comparing the distance from the house to time, we can observe that the x-intercept is when the cyclist is at home or 0 miles from their house. So the x-intercept must represent the duration of time it took the cyclist to reach home. D

3. Ok so we know the equation of the line is 3x-8y-12=0, and we're trying to find the x and y intercepts. So we can plug 0 in for x to find the y-intercept. And plug 0 in for y to find the x-intercept.

x-intercept: y=0

3x-8(0)-12=0

3x-12=0

3x=12

x=4

=> (4,0)

y-intercept: x=0

3(0)-8y-12=0

-8y-12=0

-8y=12

y=-3/2

=> (0,-1.5)

So the answer is B

4. We can see that one prize is worth $6, so in theory, if the relation was linear we should be able to say that the cost of the number of prizes you buy is 6 times the number of prizes bought. Since we can see that that is not true, we can determine that the data is non-linear. We can also tell that the data is discrete because you can't buy a partial prize. So the answer is C

I'm sorry I don't have time to finish the rest of the questions!! I hope my other answers are helpful though!

Answer:

GH = 7\sqrt{2}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{HI}{GH} = \frac{7}{GH} = \frac{1}{\sqrt{2} } ( cross- multiply )

GH = 7\sqrt{2}

alina1380 [7]

Answer:

23.714285714286

Step-by-step

The mean absolute deviation of a set of data is the average distance between each data value and the mean.

1. Find the mean.

2. Find the distance between each data value and the mean. That is, find the absolute value of the difference between each data value and the mean.

3. Find the average of those differences.
