Answer:
75 % passed
25 % did NOT pass
Step-by-step explanation:
Step 1: Add up the ages.
32+23+21+38+26=140.
Step 2: Divide answer by the amount of used numbers (5, in this case.)
140/5=28.
Your answer is 28.
17 pieces can be cut because you have to divide 12 3/4 by 3/4
Answer:
B. ![y = \frac{2}{3} x + 5](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20x%20%2B%205)
Step-by-step explanation:
Let's use the slope equation first. The slope equation is as follows:
![\frac{y2-y1}{x2-x1} = slope](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20%3D%20slope)
This is what is given in the equation:
Let's label each component of the equation using these points:
y2 = 9
y1 = 7
x2 = 6
x1 = 3
Now, plug these into the equation
![\frac{9-7}{6-3} = \frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B9-7%7D%7B6-3%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D)
We can now eliminate A and C of the answer choices.
Now let's find the y intercept
Right now we have the following equation
![y = \frac{2}{3} x+ (y intercept)](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20x%2B%20%28y%20intercept%29)
In order to find the y intercept we need to plug in one of the given points into the equation. Let's use point (3,7).
The equation should look like this now:
![7 = \frac{2}{3}(3) + (yintercept)](https://tex.z-dn.net/?f=7%20%3D%20%5Cfrac%7B2%7D%7B3%7D%283%29%20%2B%20%28yintercept%29)
Now lets solve for the y-intercept
![7 = \frac{2}{3}(3) + (yintercept)\\7 = \frac{6}{3} + (yintercept)\\7 = 2 + (yintercept) \\5 = yintercept](https://tex.z-dn.net/?f=7%20%3D%20%5Cfrac%7B2%7D%7B3%7D%283%29%20%2B%20%28yintercept%29%5C%5C7%20%3D%20%5Cfrac%7B6%7D%7B3%7D%20%2B%20%28yintercept%29%5C%5C7%20%3D%202%20%2B%20%28yintercept%29%20%5C%5C5%20%3D%20yintercept)
Now that we found the y-intercept is 5 we have our full equation!
![y = \frac{2}{3} x + 5](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20x%20%2B%205)
