What is the difference between certain and impossible?.

1 answer:

7 0

Certain events have a 100% probability of occurring, and impossible events have a 0% chance of occurring.

Theoretical probability is based on a mathematical estimate, whereas experimental probability is a probability determined based off of an experiment.

Which is bigger 11/18 or 5/14

KengaRu [80]

Among the fractions given in this question 11/18 and 5/14, the largest fraction is: 3/5.

Step-by-step explanation:

To find out which fraction is the largest, just divide the numerator by the denominator of the ratio and make the comparisons between them, thus defining which is the largest by decimal places or the largest number.

Resolution:

$\large \sf \dfrac{11}{18} \rightarrow 11\div18\rightarrow 0{,}61111111111$

$\large \sf \dfrac{5}{14} \rightarrow 5\div14\rightarrow 0{,}35714285714$

Conclusion:

We can conclude that the largest fraction, being between 11/18 and 5/14, is 11/18.

◆ Quadratic Equations ◆ Please help !

Mila [183]

I'm sure there's an easier way of solving it than the way I did, but I'm not sure what it could be. Never dealt with a problem like this before.

Anyway, I just plugged in and tested. Chose random values for a, b, c, and d, which follow the rule 0 < a < b < c < d:

a = 1
b = 2
c = 3
d = 4

$\sf ax^2+(1-a(b+c))x+abc-d)$

$\sf 1x^2+(1-1(2+3))x+(1)(2)(3)-(4))$

Simplify into standard form:

$\sf x^2+(1-1(5))x+6-4$

$\sf x^2+(1-5)x+2$

$\sf x^2-4x+2$

Use the quadratic formula to solve:

$\sf x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

For functions in the form of $\sf ax^2+bx+c$ . So in this case:

a = 1
b = -4
c = 2

Plug them in:

$\sf x=\dfrac{4\pm\sqrt{(-4)^2-4(1)(2)}}{2(1)}$

Solve for 'x':

$\sf x=\dfrac{4\pm\sqrt{16-8}}{2}$

$\sf x=\dfrac{4\pm\sqrt{8}}{2}$

$\sf x\approx\dfrac{4\pm 2.83}{2}$

$\sf x\approx 0.59,3.41$

So the answer would be A.
