Answer:
C. Yvette's independent and dependent probabilities are equal.
Step-by-step explanation:
<em>To figure this out we can use a drawing & word</em>
<em>Draw 2 marbels purple </em>
<em>Then figure out Yvette's independece & Dependece by looking at the marbels you've drawn in a notebook or scrap paper</em>
<em>Use a pencil so you erase what you put down on the paper the click the answer.</em>
Good luck Hope you get it right
remember math is math it doesn't have to be perfect as long as you keep trying. Practice makes perfect.
Hope this helps
Every prime greater than 2 is oddNo even number greater than 2 is prime
27+7 = 34
so, the answer is 34
Answer:
A: This polynomial has a degree of 2 , so the equation 12x2+5x−2=0 has two or fewer roots.
B: The quadratic equation 12x2+5x−2=0 has two real solutions, x=−2/3 or x=1/4 , and therefore has two real roots.
Step-by-step explanation:
f(x) = 12x^2 + 5x - 2.
Since this is a quadratic equation, or a polynomial of second degree, one can easily conclude that this equation will have at most 2 roots. At most 2 roots mean that the function can have either 2 roots at maximum or less than 2 roots. Therefore, in the A category, 2nd option is the correct answer (This polynomial has a degree of 2 , so the equation 12x^2 + 5x − 2 = 0 has two or fewer roots).
To find the roots of f(x), set f(x) = 0. Therefore:
12x^2 + 5x - 2 = 0. Solving the question using the mid term breaking method shows that 12*2=24. The factors of 24 whose difference is 5 are 8 and 3. Therefore:
12x^2 + 8x - 3x - 2 = 0.
4x(3x + 2) -1(3x+2) = 0.
(4x-1)(3x+2) = 0.
4x-1 = 0 or 3x+2 = 0.
x = 1/4 or x = -2/3.
It can be seen that f(x) has two distinct real roots. Therefore, in the B category, 1st Option is the correct answer (The quadratic equation 12x2+5x−2=0 has two real solutions, x=−2/3 or x=1/4 , and therefore has two real roots)!!!
