Probability=number of specific outcomes / total number of possible outcomes...
P(r)=7/(9+7+6)
P(r)=7/22 ( ≈31.82%)
Answer:

Step-by-step explanation:
we have

Solve for t
That means ----> Isolate the variable t
Multiply by b both sides to remove the fraction

Factor the variable t in the left side
![t[b+a]=b](https://tex.z-dn.net/?f=t%5Bb%2Ba%5D%3Db)
Divide by (b+a) both sides

The answer is 9
One square is equal to one. for the rest just substitute the x and y for the given values
The answer is
The side length of the square Kevin cuts is slightly less than the length the instructor required
Answer:
The slope is 
The y-intercept is 9
Step-by-step explanation:
The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where
- m is the slope of the line whose rule is
- b is the y-intercept, you can find it by substituting x, y in the equation by (x1, y1) OR (x2, y2)
Let us solve the question:
Choose any two-point from the table
∵ The line passes through the points (2, 12) and (4, 15)
∴ x1 = 2 and x2 = 4
∴ y1 = 12 and y2 = 15
→ Use the rule of m to find it
∵ 
∴ m = 
∴ The slope is 
→ Substitute its value in the form of the equation above
∴ y =
x + b
→ To find b substitute x and y by x1 and y1
∴ 12 =
(2) + b
∴ 12 = 3 + b
→ Subtract 3 from both sides
∴ 12 -3 = 3 - 3 + b
∴ 9 = b
∴ The y-intercept is 9
