There are 12 months, 7/12 have 31 days. You would have a 7/12 probability of choosing one with 31 days if it is random.
Step-by-step explanation:
go left 10 and down 2 this due to the numbers being negative.
Answer:
3, -9, 27,-81,243,-729,2187,-6561,19683,-59049,177147,-531441
the sum is −398,580
Answer:
YES
Step-by-step explanation:
Any straight line can be represented by an equation of the form
Y = mX + b
where m is the slope and b is the Y intercept, so these two equations are lines. The only solution is where the two lines cross, so must satisfy both equations. Plugging in 3 for X and -2 for Y we get
Y = -3X + 7
-2 = -3(3) + 7
-2 = -9 + 7
-2 = -2 True
AND,
Y = 2X - 8
-2 = 2(3) - 8
-2 = 6 - 8
-2 = -2 True
So since both are true, yes (3, -2) is the solution.
Answer:
the answer is approximately 48.05.
Step-by-step explanation: You can either use a calculator or estimate knowing that 50 is the square root of 2500, which is slightly above 2309. You can also use differentials and calculus to find an approximation.
