The probability of getting TTH or THH is (1/2) * (1/2) * (1/2) = 1/8, as each toss is independent and has a probability of 1/2.

To find the probability that a fair coin is flipped a multiple of three times before coming up heads, we can consider the possible outcomes. Let's denote H as heads and T as tails.

The first toss can either be T or H with equal probabilities of 1/2 each. If it's H, the experiment ends. If it's T, we move to the second toss.

For the second toss, the possibilities are TH or TT. If it's TH, the experiment ends. If it's TT, we move to the third toss.

For the third toss, the possibilities are TTH, TTT, or THH. If it's TTH or THH, the experiment ends. If it's TTT, we move to the fourth toss.

Following this pattern, we can see that the experiment ends when we get TTH, THH, TTTTH, TTTTTTH, or any sequence of T's followed by H. These are the outcomes where the coin is flipped a multiple of three times before coming up heads.

To write 45 + 3/10 + 8/1000 as a decimal, we need to convert the fractions 3/10 and 8/1000 to their equivalent decimal form and then add all three numbers. The result is 45.308, which can be simplified to 45.31 by rounding to the nearest hundredth.

Explanation:

To convert 3/10 to a decimal, we divide 3 by 10, which gives 0.3. To convert 8/1000 to a decimal, we divide 8 by 1000, which gives 0.008. We can then add 45, 0.3, and 0.008 to get:

45 + 0.3 + 0.008 = 45.308

To simplify this result to the nearest hundredth, we look at the digit in the third decimal place (8) and round the digit in the second decimal place (0) up to 1 if the third decimal place is 5 or greater. In this case, the third decimal place is 8, which is greater than 5, so we round up to get:

45.31

Therefore, 45 + 3/10 + 8/1000 is equal to 45.31 when written as a decimal.

By Simplifying the expression, [tex](π(0.175)^2 - π(0.125)^2)/π(0.175)^2 * 100.[/tex] we find the percentage reduction in the area of the sample due to the test.

To find the percentage reduction in area of the sample, we need to calculate the difference in cross-sectional areas before and after the tensile test.

The cross-sectional area of a rod can be calculated using the formula: [tex]A = πr^2[/tex], where r is the radius of the rod.

Given that the initial diameter of the rod is 0.350 inches, the initial radius (r1) is 0.350/2 = 0.175 inches. Therefore, the initial cross-sectional area (A1) is[tex]π(0.175)^2.[/tex]

Similarly, the final diameter of the rod is 0.250 inches, and the final radius (r2) is 0.250/2 = 0.125 inches. The final cross-sectional area (A2) is [tex]π(0.125)^2[/tex].

Now, we can calculate the percentage reduction in area using the formula: (A1 - A2)/A1 * 100.

Substituting the values, we have: [tex](π(0.175)^2 - π(0.125)^2)/π(0.175)^2 * 100.[/tex]

Therefore, by Simplifying the expression, we find the percentage reduction in the area of the sample due to the test.

Answer:

Length = 6.49 cm

Step-by-step explanation:

The formula for area of a rectangle is

A = lw, where

Since we're already given the area and width and want to find the length, we can first rewrite the area formula in terms of l:

A/w = l

Now, we can plug in 25.311 for A and 3.9 for w to solve for l, the length:

25.311 / 3.9 = l

6.49 cm = l

We can check that 6.49 is the correct length by plugging everything into the regular area formula and checking that we get 25.311:

25.311 = 6.49 * 3.9

25.311 = 25.311

Simplify in steps:

Therefore, the probability of drawing exactly 3 aces, 2 queens, and 1 king is approximately 0.000682.

We can solve this problem using the multiplication rule for independent events. The probability of drawing a specific card from a standard deck is 1/52, since there are 52 cards in the deck and each is equally likely to be drawn. We can use this probability to find the probability of drawing a specific combination of cards.

(a) To find the probability of drawing exactly 3 aces, 2 queens, and 1 king, we can break it down into three steps:

Find the probability of drawing exactly 3 aces: There are 4 aces in the deck, so the probability of drawing an ace on the first draw is 4/52. Since we need exactly 3 aces, the probability of drawing 3 aces and 3 non-aces (out of the remaining 48 cards) is given by the binomial probability formula:

P(3 aces) = (4/52)^3 * (48/52)^3 * C(6,3)

where C(6,3) is the number of ways to choose 3 cards out of 6. Using a calculator, we get:

P(3 aces) = 0.0080

Find the probability of drawing exactly 2 queens: There are 4 queens in the deck, so the probability of drawing a queen on the first draw is 4/52. Since we need exactly 2 queens, the probability of drawing 2 queens and 4 non-queens (out of the remaining 48 cards) is given by:

P(2 queens) = (4/52)^2 * (48/52)^4 * C(6,2)

where C(6,2) is the number of ways to choose 2 cards out of 6. Using a calculator, we get:

P(2 queens) = 0.2123

Find the probability of drawing exactly 1 king: There are 4 kings in the deck, so the probability of drawing a king on the first draw is 4/52. Since we need exactly 1 king, the probability of drawing 1 king and 5 non-kings (out of the remaining 48 cards) is given by:

P(1 king) = (4/52)^1 * (48/52)^5 * C(6,1)

where C(6,1) is the number of ways to choose 1 card out of 6. Using a calculator, we get:

P(1 king) = 0.4017

Now we can use the multiplication rule to find the probability of drawing exactly 3 aces, 2 queens, and 1 king:

P(exactly 3 aces, 2 queens, 1 king) = P(3 aces) * P(2 queens) * P(1 king)

= 0.0080 * 0.2123 * 0.4017

Jose will get something other than a 2.  If Jose uses the random number generator 500 times, we can predict that he will get a result other than a 2 approximately 375 times (75% of 500).

It is highly likely that Jose will get something other than a 2 at least once during the 500500 times he uses the random number generator. This is because the generator produces 1, 2, 3, 1, comma, 2, comma, 3, comma, or 4 with equal probability, and there are 4 possible outcomes. Therefore, the probability of getting a 2 is only 1/4 or 25%. This means that there is a 75% chance of getting something other than a 2.

To further support this prediction, we can use the law of large numbers, which states that as the number of trials increases, the experimental probability of an event will converge to the theoretical probability. In this case, as Jose uses the random number generator more and more times, the percentage of times he gets a 2 should get closer and closer to 25%. Therefore, it is highly likely that Jose will get something other than a 2 at least once during the 500500 times he uses the generator.

In order to provide you with an accurate answer, let's rephrase the question with the relevant information:

Jose is going to use a random number generator 500 times. Each time he uses it, he will get a 1, 2, 3, or 4. Complete the following statement with the best prediction: Jose will get something other than a 2.

Since the random number generator can produce four possible outcomes (1, 2, 3, and 4), each outcome has a 25% chance of occurring.

Therefore, the probability of getting something other than a 2 is 75% (25% for each of the other three outcomes). If Jose uses the random number generator 500 times, we can predict that he will get a result other than a 2 approximately 375 times (75% of 500).

The volume of Cylinder #2 is about 157 cm³ greater than the volume of Cylinder.#1 The correct answer is D. 157 cm³.

To compare the volumes of the two cylinders, we will use the formula for the volume of a cylinder, which is V = πr²h, where V is the volume, r is the radius, and h is the height.
Cylinder #1:
Radius (r1) = 5 cm
Height (h1) = 18 cm
Volume of Cylinder #1 (V1) = π × r1² × h1 = π × 5² × 18 = π × 25 × 18 = 450π cm³
Cylinder #2:
Radius (r2) = 5 cm (same as Cylinder #1)
Height (h2) = 20 cm
Volume of Cylinder #2 (V2) = π × r2² × h2 = π × 5² × 20 = π × 25 × 20 = 500π cm³
Now, we will find the difference in volumes:
Difference = V2 - V1 = 500π cm³ - 450π cm³ = 50π cm³ ≈ 157 cm³
So, the volume of Cylinder #2 is about 157 cm³ greater than the volume of Cylinder #1. The correct answer is D. 157 cm³.

The total number of dolls they had in the beginning was 35, and after Jacky gave Peter 15 dolls, they each had 25 dolls. So, they had a total of 50 dolls in all.

Let the initial number of dolls Jacky had be 5x, and the initial number of dolls Peter had be 2x. So, the total number of dolls they had in the beginning was 5x + 2x = 7x.

After Jacky gave Peter 15 dolls, Peter had (2x + 15) dolls, and Jacky had (5x - 15) dolls. As they had an equal number of dolls after this, we get the equation:

5x - 15 = 2x + 15

Simplifying this, we get:

3x = 30

x = 10

So, the initial number of dolls Jacky had was 5x = 50, and the initial number of dolls Peter had was 2x = 20. Therefore, the total number of dolls they had in the beginning was 50 + 20 = 70.
