Answer:
z=-3
Step-by-step explanation:
The given line has slope m=-7.
The line passes through (-1,-8) and (z,6).
We use the slope formula:
We substitute

The die can land in 6 different ways.
Only one of them is a 2.
So the probability of rolling a 2 on any roll is 1/6 .
In a large number of rolls, you expect roughly 1/6 of them to be a 2.
In 108 rolls, you should expect a 2 somewhere around
(108/6) = 18 times.
Answer:
add all given angle
sum of all angles is equal to 180 degree
Answer:
The third one, (x+5)^2 + (y+7)^2 = 74
Step-by-step explanation:
The equation for a circle is in the form (x-x coordinate)^2 + ( y - y coordinate )^2 = r^2
the radius is 5^2 + 7^2 = 25 + 49 = 74
and the center is (-5,-7), so it is + 5 and + 7
