No, -(5/11) is equivalent to -5 all over 11 so -5/11. You cannot change the denominator

Suppose that you are taking a T/F exam and you have no idea at all about the answers to the last three questions. You choose ans

podryga [215]

Answer:

0.375, 0.125, 0.5

Step-by-step explanation:

given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.

Probability for correct guess = 0.5 remains constant for each of the three questions

X - no of questions is binomial with n =3 and p = 0.5

1) the probability that you guessed right on exactly one of the three questions

= P(X=1)

= $3C1(0.5)^3 = 0.375$

2) the probability that you guessed right on zero of the three questions

= $P(X=0)\\= 0.5^3=0.125$

3) the probability that you guessed right on at least two of the questions

= $P(x=3)+P(2)\\= 1-0.5\\=0.5$

Can anyone show me the steps and answer?

Answer:

(-∞, 3) ∪ (3, 4) ∪ (4, ∞)

Step-by-step explanation:

<u>Steps</u>:

1. Read and understand the question. Here, you're being asked for the domain of a rational function, one with a 2nd-degree polynomial in the denominator. The domain is the set of x-values for which the function is defined.

2. Understand that the function will be undefined when the denominator is zero, so to answer the question, you must find the values of x that make the denominator zero.

3. Use any of the methods you have been taught to determine the zeros of the denominator polynomial. For this one, it is convenient to factor it:

x² -7x +12 = (x -3)(x -4)

The values of x that make this zero are 3 and 4, so these values are excluded from the domain.

4. Write an expression in interval notation that includes all real numbers except 3 and 4. That is, you want to translate this to interval notation:

(-∞ < x < 3) ∪ (3 < x < 4) ∪ (4 < x < ∞)

Using what you know about interval notation, you write it as ...

(-∞, 3) ∪ (3, 4) ∪ (4, ∞)

PLEASE HELP I REALLY NEED IT

Aleonysh [2.5K]

Answer:

9. Force is required to change an object velocity.Force is equal to mass times acceleration.

10. Force acting on object are paired with equal and opposite forces

Step-by-step explanation:

Newton's 2nd law states that force is a product of mass and acceleration.In this case, the force of friction is causing deceleration of the ball.This is an example of rolling friction.Acceleration of the ball depends directly on this friction but indirectly on its mass.

10.

From Newton's 3rd Law ,for every action there is an equal and opposite reaction.The astronaut throwing the ball will experience the effect of an external force againts his own which is equal and in the opposite direction to the force she applied.This is why the astronaut moves backward but slower.
