Answer:

- 1/3 × (-3/7) = 1/7

Step-by-step explanation:

Remember that a negative factor times a negative factor has a positive product.

Multiply each side by -1 to remove negatives, Then multiply straight across.

1/3 × 3/7 = 3/21   Simplify: divide numerator and denominator by 3.

3÷3=1    21÷3=7  

1/7

Let's break down this problem step by step.

First, let's understand what's happening here. There's a carnival game where you can pick one duck from a pond. Each duck has a mark under it that might make you a winner of a prize. Some ducks are marked with large prizes, some with medium, some with small, and the rest don't win you any prize.

The total number of ducks in the pond is 73.

Out of these 73 ducks:

- 5 are marked for a large prize,

- 11 are marked for a medium prize,

- 24 are marked for a small prize.

We are asked to find the theoretical probability of picking a duck that has a medium prize mark. The theoretical probability is basically a fraction that compares the number of ways something can happen with the total number of outcomes.

Here, the number of ways you can win a medium prize is equal to the number of ducks that have a medium prize mark, which is 11.

The total number of outcomes is just the total number of ducks you can choose from, which is 73.

The probability (P) of winning a medium prize is then:

P(medium prize) = (Number of medium-prize ducks) / (Total number of ducks)

= 11/73

To convert this fraction to a decimal, simply divide 11 by 73:

= 11 ÷ 73

≈ 0.1507 (rounded to the nearest thousandth)

So, the probability of winning a medium prize at the duck pond is about 0.151 or 15.1%. Imagine, for every 100 ducks you pick (if there were that many), about 15 of them would win you a medium prize.

The theoretical probability of winning a medium prize at the duck pond is ≈ 0.150

To find the theoretical probability of winning a medium prize at the duck pond, we need to determine the ratio of the number of medium-prize-winning ducks to the total number of ducks in the pond.

The total number of ducks in the pond is given as 73.

The number of medium-prize-winning ducks is given as 11.

Therefore, the probability can be calculated as follows:

Probability of winning a medium prize = (Number of medium-prize-winning ducks) / (Total number of ducks)

Probability of winning a medium prize = 11 / 73

To express the answer as a decimal, we divide 11 by 73:

Probability of winning a medium prize ≈ 0.150

Rounded to the nearest thousandth, the theoretical probability of winning a medium prize at the duck pond is approximately 0.150

Answer:

16.2

Step-by-step explanation:

    This question is all about how far the ant walks, but you just need to split it up into little pieces to make it seem less daunting.

    First you need to figure out where the ant is on the number line after all of that walking. We can break it down into a more mathematical sense. When the ant walks Left, it represents negative numbers, or numbers you should subtract since whenever the ant walks left, it is getting closer to the zero, or becoming a smaller number. Right represents positive numbers, or numbers you should add, since when the ant walks right, it is getting further away from the zero or becoming a bigger number. Now, we need to add the numbers together. 3.5 centimeters left should be -3.5 for the reason above, and 4.8 centimeters right should be + 4.8 for the reason above. Finally, 7.9 Centimeters left should be -7.9.

    Now, we need to add them together in order. The ant starts at positive 2 centimeters. Then, it goes 3.5 centimeters left. 2 minus 3.5 is -1.5 cm. Then, the ant travels 4.8 centimeters right. -1.5 cm plus 4.8 is 3.3 cm. Finally, the ant moves 7.9 cm left. 3.3 minus 7.9 is -4.6 cm. This is the new position of the ant, for part A.

    Part B you just need to find the difference between 2, and -4.6. This involves absolute value. How far away from the zero is -4.6 centimeters. 4.6 centimeters. It is that easy. Now, you add the two absolute values together. The absolute value of 2 is 2, because it is 2 centimeters away from zero, and 2 plus 4.6 is 6.6. That is the answer to part B.

    The total distance the ant travels is also about absolute value. Remember that absolute value numbers can NEVER be negative because a number cannot be negative units away from zero. So you just add all of the values together to get the total distance the ant travelled. 3.5 plus 4.8 plus 7.9. DON'T add your two into this value, because that's where the ant started, not a distance that it traveled. The answer should be 16.2 for part C.

You're welcome, stranger :)

The position of the ant is required at various times.

The ant is at \(-4.6\)

Distance from original location is 6.6 cm.

Distance covered is 16.2 cm.

The situation will be, the ant is at +2 and walks 3.5 cm right then 4.8 cm left then 7.9 cm right.

The ant's initial location is at \(+2\).

If the distance is left then the added number will be negative.

If the distance is right then the added number will be positive.

\(2-3.5=-1.5\)

\(-1.5+4.8=3.3\)

\(3.3-7.9=-4.6\)

So, the ant is at \(-4.6\) on the number line.

Distance between initial and final location is

\(2-(-4.6)=6.6\ \text{cm}\)

Total distance the ant covered is

\(3.5+4.8+7.9=16.2\ \text{cm}\)

The situation will be, the ant is at +2 and walks 3.5 cm right then 4.8 cm left then 7.9 cm right.

Answer:

\(\displaystyle f[g(2)] = 3\)

Step-by-step explanation:

We are given the two functions:

\(\displaystyle f(x) = -2x - 1\text{ and } g(x) = -x\)

And we want to find the value of:

\(\displaystyle f[g(2)]\)

First, evaluate g(2):

\(\displaystyle \begin{aligned} g(2) &= -(2) \\ &= -2\end{aligned}\)

Substitute:

\(\displaystyle f[g(2)] = f(-2)\)

Evaluate f(-2):

\(\displaystyle \begin{aligned} f(-2) &= -2(-2) - 1 \\ &= 4 - 1 \\ &= 3\end{aligned}\)

Therefore:

\(\displaystyle f[g(2)] = 3\)

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.
