On a number line, what other number is the same distance from -2.8 as -7.2 is?​

Answers

Answer;

1.6

Explanation

What we shall do here is to calculate the distance between the two points on the number line

Mathematically, that would be ;

-2.8 -(-7.2) = -2.8 + 7.2 = 4.4

This means that -7.2 is 4.4 units away from -2.8

So to find other number which is this same distance;

we have -2.8 + 4.4 = 1.6

Corrupted by their power, the judges running the popular game show America’s Next Top Mathematician have been taking bribes from many of the contestants. During each of two episodes, a given contestant is either allowed to stay on the show or is kicked off. If the contestant has been bribing the judges, she will be allowed to stay with probability 1. If the contestant has not been bribing the judges, she will be allowed to stay with probability 1/3, independent of what happens in earlier episodes. Suppose that 1/4 of the contestants have been bribing the judges. The same contestants bribe the judges in both rounds. (a) If you pick a random contestant who was allowed to stay during the first episode, what is the probability that she was bribing the judges? (b) If you pick a random contestant, what is the probability that she is allowed to stay during both episodes? (c) If you pick a random contestant who was allowed to stay during the first episode, what is the probability that she ge

Answers

Answer:

(a) The probability that a contestant allowed to stay in the first episode is 0.5

(b) The probability that a contestant will be allowed to stay during both is 0.25

Step-by-step explanation:

The given parameters are;

The probability that a contestant who has been bribing the judges will be allowed to stay = 1

The probability that a contestant who has mot been bribing the judges will be allowed to stay = 1/3

The proportion of the contestant that has been bribing the judges = 1/4

The contestant who bribe the judges in the first round = The contestants who bribe the judges in the second round

(a) Let the total number of contestants = x

Therefore;

The number of contestants in the second round = x/4 + 1/3×(x - x/4) = x/2

Which gives that, half of the contestants make it to the second round

The probability that a contestant allowed to stay in the first episode, Pₐ₁, is given as follows;

Probability = (The number of required outcome)/(The number of possible outcome)

∴ Pₐ₁ = (x/4)/(x/2) = 2/4 = 1/2 = 0.5

The probability that a contestant allowed to stay in the first episode = 0.5

(b) The probability that a contestant will be allowed to stay during both episode, Pₐ₁₂ is given as follows;

The number of contestant that will be allowed to stay after each episode = 1/2×(The number contestant in the previous episode)

Therefore;

The number of contestant that will be allowed to stay after the first episode = 1/2 × x = x/2

The number of contestant that will be allowed to stay after the second episode = 1/2 × x/2 = x/4

Therefore, the number of contestant that will be allowed to stay after both episode = x/4

Pₐ₁₂ = (The number of contestant that will be allowed to stay after both episode)/(The total number of contestants)

∴ Pₐ₁₂ = (x/4)/x  = 1/4 = 0.25

The probability that a contestant will be allowed to stay during both = 0.25.

Expression for the number of tiles Felicia used : 5x + 5



How could you change the equation so it has infinitely many solutions? What would infinitely many solutions mean in terms of the situation?

Answers

To determine whether they used the same number of tiles, set the two expressions equal to each other and solve for x. Is there a solution for x? Why or why not? If there is a solution, what is it?

5x +2 = 5x + 5 (subtract 5x and 2 on both sides)

0 = 3 No solution

How could you change the equation so it has infinitely many solutions?

Have 2 or 5 change because they need to be equal to each other. Its fine what you put as long as the equal sign is the same as the other side like 3 = 3 for example or 5 = 5, something like that. Once they have the same end then you can substitute the number to x.

2x - 3x = 33

what is it .?​

Answers

Answer:

- 33

Step-by-step explanation:

Step 1:

2x - 3x = 33       Equation

Step 2:

- x = 33      Subtract

Answer:

x = - 33

Hope This Helps :)

The solution to the equation 2x - 3x = 33 is x = -33.

To solve the equation 2x - 3x = 33, we need to combine like terms on the left side of the equation and then solve for x.

Combine like terms:

2x - 3x = -x

Rewrite the equation with the combined terms:

-x = 33

To isolate x, we need to multiply both sides of the equation by -1:

(-1)(-x) = (-1)(33)

This simplifies to:

x = -33

Therefore, the solution to the equation 2x - 3x = 33 is x = -33.
