Let me help you!
What we have so far:
Number of times the event occured = 0
Total number of times the event was performed = 0
We will use the empirical probability formula for this problem:
Empirical probability formula = Number of times the event occured / Total number of times the event was performed
Solving for the porblem:
Empirical probability formula = 0.
*** Without even solving the problem, you can take the word "NO" as a hint that there's simply no chance any woman can beak the 10 seconds barrier in a 100 meter run.
Therefore, there is 0 probability that a woman will break the 10 seconds barrier in a 100 meter run.
Answer:
below the x-axis
Step-by-step explanation:
y=x^2+2x-3
the vertex is located on the axis of symmetry
h
to find h ax^2 +bx+c
h= -b/2a = -2/2(1) = -1
the x coordinate of the vertex is -1
to find the y coordinate, substitute into the equation
y = (-1)^2 +2(-1) -3
= 1-2-3
= -4
(-1,-4)
the vertex is below the x axis
The answer
to do the calculus, the method is
taking off the paranthesis
adding the term with a similar degree
summing constant terms
(3x^2+3x+5) + (7x^2-9x+8) =
= 3x^2+3x+5 + 7x^2-9x+8
= 3x^2 + 7x^2 + 3x+5 - 9x+8
= 10x² + 3x - 9x +5 +8
= 10x² - 6x + 13
the answer is
(3x^2+3x+5) + (7x^2-9x+8) =10x² - 6x + 13
the error that Lucia did make 3x - 9x = -12x, instead of 3x - 9x = -6x
The answer is: 5/6 or 0.833333
Answer:
One is 3 to 4th power
(3 x 3) x (3 x 3)
Step-by-step explanation:
the other is
3 to 3rd power divided by nine to the fourth power...
(3 x 3) x 3 = 27
(9 x 9 ) x (9 x 9) = 2187
2187 / 27 = 81
