On any day, the probability his bus is late is 0.3.
The following tree diagram shows the possibilities as to his timing for school on Monday and Tuesday
Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.
(To complete the square divide the coefficient by 2 and square it).
Add those terms to the full equation. Add 36 and 49 to the right side as well
Simplify the x and y terms into a binomial.
Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.
So our center is (-7,6)
Our radius is 4.
-1., 1, 2, 2
Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them.
Answer:
x = 30°
Step-by-step explanation:
5x + x + x + 5x = 360° ( exterior angle property)
12x = 360°
x = 360/12
x = 30°
