If the first die is a 5, the second must be 5 or more in order to have a sum of at least ten.
Assuming it is a six sided die, the two values that would make this true are 5 and 6.
2 values/6 possible would be a probability of 2/6, which simplifies to 1/3
Final answer: 1/3
If the cosine is 1/2, and the angle is acute, then the angle is 60 degrees. Using the rules for a 30-60-90 right triangle, hyp=2 times the short leg. So 7/2= 3.5.
Answer:
C. Equation: x=4
D. Slope: undefined
Step-by-step explanation:
If a line is perpendicular to the x-axis, then it is a vertical line because the x-axis is horizontal.
The slope of a vertical line is undefined.
The equation of a vertical line through
is 
Since the vertical line passes through (4,-2), its equation is

The population would grow 1309 people (total 39,809)
