Which of the following statements is not true? A. If the probability of an event occurring is 0, then it is impossible for tha

FromTheMoon [43]

Answer:

C. If the probability of an event occurring is 1.5, then it is certain that the event will occur.

Step-by-step explanation:

Probability is a value between <em>0 and 1</em> (including both values). Thus, to say that there is a probability of 1.5 is not correct, and, therefore, this statement is not true.

We can rewrite the statement as "If the probability of an event occurring is 1, then it is completely certain that the event will occur."

Statement A.

Suppose the event is A. Then, if P(A) = 0, it is completely certain that the event will not occur. It is true.

Statement B.

$\\ if P(A) = 0\;then\;P(\overline{A}) = 1 - 0 = 1$ . Then, the statement is true.

Statement C.

We already explained the <em>statement C is not true</em> because the values for probabilities are between 0 and 1 (including both values). A probability of 1.5 is meaningless as a result.

Statement D.

For the same reason explained in C, the probability can never be a negative value. So, this statement is also true.

Greeley [361]

Answer: $\boxed{Sol=\{\dfrac{7}{4} \}}\\$

I suppose 17x^ means 17x².

and that we must solve the equation.

Step-by-step explanation:

$(x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\$

Reptile [31]

Answer:

A=SqRt(c^2-b^2)

Step-by-step explanation:

a^2 + b^2 = c^2

rearrange to solve for a^2

a^2= c^2-b^2

take the square root of each side

a= square root (c^2-b^2)
