Answer: 390

Step-by-step explanation:

Answer:

340

Step-by-step explanation:

with every number 0-4 stays with the 10's group that it was in to begin with. and numbers past that go to the next 10's group. so for this question you have 385. you have to move the 5 to a 10. therefor you have 390

Considering both sample size and sample estimate, The Herald with a sample size of 1000 and an estimate of 61% is likely the most accurate representation of the population proportion of voters supporting the governor, assuming all else is equal and the sampling method is consistent across surveys.

To estimate the actual percentage of voters who support the governor for reelection, we need to consider both the sample size and the sample estimate from each newspaper. Generally, larger samples provide more reliable estimates. However, we must also recognize that random sampling variability could lead to different sample estimates.

The results from the newspapers are:

In this scenario, The Herald has the largest sample size, which suggests that its result (61%) is likely the most accurate representation of the true population parameter, if all other factors such as sampling method are equal. The larger the sample size, the smaller the margin of error in estimating a population proportion, and typically the closer the estimate is to the actual value. Therefore, The Herald's estimate is likely closest to the true proportion of voters supporting the governor for reelection.

Answer:

1297.37 feet.

Step-by-step explanation:

Given:

The carousel at a local theme park has a diameter of 32 feet.

Each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute.

Question asked:

What is the maximum distance riders travel in one full ride? Round to the nearest hundredth.

Solution:

First of all we will find the radius of the carousel:-

Diameter = 32 feet

Radius, r = [tex]\frac{Diameter}{2} =\frac{32}{2} =16\ feet[/tex]

Now, we will find distance covered by the carousel in one ride that means its circumference;

[tex]Circumference\ of \ the \ circle=2\pi r[/tex]

                                               [tex]=2\times\frac{22}{7} \times16\\ \\ =\frac{704}{7} \\ \\ =100.571\ feet[/tex]

In 1 minute, number of revolution taken by carousel = 4.3

As each ride last for 3 minutes:-

In 3 minutes, number of revolution taken by carousel = 3 [tex]\times[/tex] 4.3 = 12.9

In 1 revolution, distance covered by carousel = 100.571 feet

In 12.9 revolution, distance covered by carousel = 100.571  [tex]\times[/tex] 12.9

                                                                                 = 1297.365 feet

Thus, the maximum distance riders travel in one full ride is 1297.37 feet.

Answer:

The answer is option 4.

Step-by-step explanation:

It is given that the diameter of a wheel is 622 mm so in order to find its radius you have to divide it by 2 :

diameter = 622 mm

radius = 622 ÷ 2

= 311 mm

Next you have to use the formula of circumference of circle, C = 2×π×r where r represents radius :

Let π be 3.14,

Let r be 311 mm,

C = 2×3.14×311

= 1953.08 mm

Answer:

mean: 3.2 standard deviation: 1.4

Step-by-step explanation:

its correct

The mean number of males selected each month is 3.2, and the standard deviation is approximately 1.4 males.

The student's question is about finding the mean and standard deviation of the number of males selected each month to have lunch with the CEO in a division of a company. Given that 40% of the employees are male, we can determine the mean number of males selected for the lunch by multiplying the percentage of males by the number of employees selected each month, this is known as the expected value, E(X) = np. Since 40% of over 200 employees are male, we assume we have at least 80 males (0.40 x 200) in the division. If 8 employees are selected at random, the mean number of males expected, μ, would be 40% of 8, or 3.2 males.

To find the standard deviation, σ, we use the formula for the standard deviation of a binomial distribution, which is σ = sqrt(np(1-p)), where p is the probability of choosing a male (0.40) and n is the total number selected (8). In this case, the standard deviation is σ = sqrt((8)(0.40)(0.60)) and rounding to the nearest tenth gives us σ ≈ 1.4.

Final answer:

To construct an equilateral triangle inscribed in a circle, the correct steps are to construct two diameters using the points where the arc intersects the circle and the center, and then connect the endpoints of the two diameters.

Explanation:

The correct step used in the construction of an equilateral triangle inscribed in a circle is to construct two diameters using the points where the arc intersects the circle and the center. This will create a cross shape inside the circle. Then, you connect the endpoints of the two diameters to form the equilateral triangle. This is because the lengths of the radii of the circle are equal, and connecting the points where the arc intersects the circle with the center creates two congruent radii.

Answer: 125,000 BTUs

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

A fuel tank has a volume of 36 gallons. When filled with biodiesel, it provides 4,500,000 BTUs

So, the proportion is:

36 gallons / 4,500,000 BTUs

For 1 gallon  

1 gallon / x BTUs

36/4,500,000 = 1/x

Solving for x:

x = 1 / (36/4,500,000)

x = 125,000 BTUs

Answer:

7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6

Step-by-step explanation:

7 3/4 + 1 3/4 - 3 5/6

we do not want the minus sign.

7 3/4 + 1 3/4 - 3 5/6 = 7 3/4 + 1 3/4 - 3  -   5/6

7 3/4 + 1 3/4 - 3 5/6 =  7+  3/4 + 1 +  3/4 - 3  -  5/6

7 3/4 + 1 3/4 - 3 5/6 = 7 + 1 - 3 + 3/4 + 3/4 - 5/6

7 3/4 + 1 3/4 - 3 5/6 = 5 + 3/4 + 3/4 - 5/6

7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1 - 5/6

7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6

To rewrite the expression 7 3/4 + 1 3/4 - 3 5/6 using addition instead of subtraction, we can change the sign of the subtraction term and find the common denominator to add the fractions.

To rewrite the expression 7 3/4 + 1 3/4 - 3 5/6 using addition instead of subtraction, we can change the subtraction to addition by changing the sign of the second term. So the expression becomes:

7 3/4 + 1 3/4 + (-3 5/6)

Now, to add fractions with different denominators, we need to find the common denominator. In this case, the common denominator is 12.

Converting all the fractions to have a denominator of 12, we get:

7 9/12 + 1 9/12 + (-3 10/12)

Adding the numerators, we have:

7 + 9 + 1 + 9 - 3 - 10 = 13

So the expression 7 3/4 + 1 3/4 - 3 5/6, using addition instead of subtraction, is equal to 13.

Answer:

A)

Step-by-step explanation:

The theorem states that if a right triangle has two sides equal to a and b, and a hypotenuse equal to c, then a squared plus b squared equals c squared.

the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

Final answer:

A) 'All of the answers are correct.' would be the best answer.

Explanation:

The correct answer to the question 'Which of these best describes the Pythagorean theorem?' is option C), which states 'The sum of the squares of the smaller sides of a right triangle equal the square of the largest side.'

However, option D) 'A-squared plus B-squared equals C-squared.' is also a correct representation of the theorem. Therefore, if all given options were correct representations of the theorem, then the best choice would be A) 'All of the answers are correct.'

The Pythagorean theorem is a fundamental principle in geometry that relates the lengths of the sides of a right triangle. Specifically, it states that the square of the length of the hypotenuse (side c) is equal to the sum of the squares of the lengths of the other two sides (sides a and b).

This relationship can be expressed with the formula a² + b² = c², where c represents the hypotenuse and a and b represent the legs of the right triangle.

If one needs to find the length of the hypotenuse, one can use the formula c = √(a² + b²).

Heads, Tails, Heads, Tails

Step-by-step explanation:

So Bob and Larry both wanted a cookie, but the problem was the there was only one cookie

So they decided to settle this like the grown men that they are, and toss a coin three times to see who would get the cookie. Bob called heads, and Larry called tails. They had Bobs older brother Timmy flip the coin to make it fair. Timmy flipped the coin, it landed on heads. Bob scream "LETS GOOO!!" Larry was upset. But when Timmy flipped it a second time, it landed on tails. Larry's heart filled with joy as he thought of that delicious, chocolate chip cookie from Abbey. The final flip... Both Bob and Larry knew that the next one that it landed on would win that cookie... Timmy flipped it one last time.. and it landed on heads. Bob smiled cheek to cheek, and was about to get up to get the cookie. Larry's eyes started to water up. He really wanted that cookie, and to watch his best friend talk the love of his life made him sad. Bob saw this, and asked Timmy to flip the coin one more time. Both Timmy and Larry looked at him with confusion. But, Timmy did as he asked, and then it landed on tails. It was a tie. Bob wen to get the cookie, split it in half, and gave it to Larry. Both of them, happily eatting the cookie walked off into the sunset, to continue both of their journeys.

THE END

Final answer:

The probability of getting the sequence HTHT when flipping a coin four times in a row is 1/16 or 0.0625, which is approximately 6.25%.

Explanation:

In this question, we are asked about the probability of getting the sequence HTHT when flipping a coin four times in a row.

To calculate the probability, we need to find the total number of possible outcomes and the number of outcomes that match the desired sequence. Each coin flip has two possible outcomes, heads (H) or tails (T), so when flipping a coin four times, the total number of possible outcomes is 2⁴ = 16.

Out of the 16 possible outcomes, only one outcome matches the sequence HTHT. Therefore, the probability of getting the sequence HTHT when flipping a coin four times in a row is 1/16 or 0.0625, which is approximately 6.25%.
