It wont let me see the pic sorry
try again
Answer:
Since there are 2 possibilities for each bat (hit or out), the amount of total possibilities is 2 * 2 * 2 = 8. There is only one possibility out of those eight that gives us three hits, therefore the probability is 1 / 8 or 0.125.
Answer:
2. ![y=\frac{1}{2}x +3](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%20%2B3)
Step-by-step explanation:
2. The line will be parallel to the current track which means they have the same slope. To write the equation, use the slope m=1/2 and the point (2,4) in point slope form:
![y-y_1=m(x-x_1)\\y-4=\frac{1}{2}(x-2)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5C%5Cy-4%3D%5Cfrac%7B1%7D%7B2%7D%28x-2%29)
This is the equation of the line. You can convert it to slope intercept form:
![y-4=\frac{1}{2}(x-2)\\y-4 = \frac{1}{2}x -1 \y=\frac{1}{2}x +3](https://tex.z-dn.net/?f=y-4%3D%5Cfrac%7B1%7D%7B2%7D%28x-2%29%5C%5Cy-4%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20-1%20%5Cy%3D%5Cfrac%7B1%7D%7B2%7Dx%20%2B3)
Answer:
y = ![\frac{25}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B6%7D)
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 5 when x = 6
k =
= ![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)
y =
x ← equation of variation
When x = 5, then
y =
× 5 = ![\frac{25}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B6%7D)
