The guests in the birthday party ate 33 cookies.

We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.

Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.

6 1/4 dozen = 25/4 dozen

3 1/2 dozen = 14/4 dozen

Now we can subtract the number of cookies that were left from the number of cookies that were made:

25/4 - 14/4 = 11/4 dozen

To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.

There are 12 cookies in one dozen, so:

11/4 x 12 = 33

Therefore, the guests ate 33 cookies.

The probability that all four people regularly use seat belts is approximately 0.656 or 65.6%.

To find the probability that all four people regularly use seat belts, we need to use the multiplication rule of probability which states that the probability of two or more independent events occurring together is the product of their individual probabilities.

The probability that the first person uses a seat belt is 0.901, and assuming that the events of seat belt use by different people are independent, the probability that the second person also uses a seat belt is 0.901.

The probability that the third person uses a seat belt is also 0.901, and the probability that the fourth person uses a seat belt is also 0.901.

Therefore, the probability that all four people regularly use seat belts is:

P(all four use seat belts) = P(person 1 uses seat belt) x P(person 2 uses seat belt) x P(person 3 uses seat belt) x P(person 4 uses seat belt)

P(all four use seat belts) = 0.901 x 0.901 x 0.901 x 0.901

P(all four use seat belts) = 0.656

The likelihood that the average tariff rate of 400 shipments of ethanol picked at random will be inside $80 of the average tariff rate of all shipments is roughly 0.789, or 78.9%.

The probability that an event will occur or that a proposition is true is quantified by probability theory, a branch of mathematics. A number from zero to one, where 0 approximately indicates how likely the event will happen and 1 generally indicates certainty, is the probability given an occurrence. In mathematics, probability is a measure of how likely an event is to take place. Probability levels can also be expressed as percent between 0 and 100 percent in addition to the numerals 0 to 1. the percentage of all outcomes out of all equally likely alternatives that lead to a specific occurrence, represented as a ratio.

given,

To solve this problem, we need to use the central limit theorem, which states that the distribution of sample means is approximately normal, with mean equal to the population mean and a standard deviation determined by dividing the population's standard deviation by the sample size square root.

We are given that the standard deviation of the population of tariff rates is $1200. Let mu be the population mean tariff rate, and x-bar be the sample mean tariff rate. We want to find the probability that the sample mean is within $80 of the population mean, i.e., |x-bar - mu| <= $80.

Using the formula for the standard error of the mean, we have:

SE = sigma/sqrt(n) = $1200/sqrt(400) = $60

Now, we can standardize the variable z = (x-bar - mu)/SE, and find the probability of |z| <= 80/60 = 4/3 using a standard normal distribution table or calculator.

P(|z| <= 4/3) = 0.7887

Therefore, the probability that the mean tariff rate of 400 randomly selected railroad-car shipments of ethanol will be within $80 of the mean tariff rate of all railroad-car shipments of ethanol is approximately 0.789 or 78.9% (rounded to three decimal places).

Interpretation: Sampling error refers to the natural variation in sample statistics (such as the sample mean) that occurs due to chance, even when the sample is randomly selected and representative of the population. In this case, the probability of the sample mean tariff rate being within $80 of the population mean is high (78.9%), which suggests that the amount of sampling error in estimating the population mean using a sample of 400 observations is relatively small.

The diameter of the circle is approximately 947.15 meters.

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference and r is the radius of the circle.

We can use this formula to find the radius of the circle given its circumference:

C = 2πr

942 = 2πr

Dividing both sides by 2π, we get:

r = 942/2π

Now, we can use the formula for the diameter of a circle in terms of its radius:

d = 2r

Substituting the value we found for r, we get:

d = 2(942/2π) = 942/π

Using a calculator to approximate π as 3.14, we can evaluate the expression to get:

d ≈ 947.15 meters

Therefore, the diameter of the circle is approximately 947.15 meters.

There are 65,000 possible passwords of length 5 that can be made with no repeats allowed.

What is length?

Length is a measure of distance between two points or the extent of something along its longest dimension. It is one of the basic dimensions in geometry and can be defined as the distance between two points measured in one dimension, typically along a straight line.

Since at least one character must be a symbol, there are 5 choices for the first character. For the remaining four characters, there are 10 choices (0 to 9) for each character if digits are allowed, 26 choices (a to z) for each character if lowercase letters are allowed, and 5 choices for each character if the other symbols are allowed.

Therefore, the total number of passwords of length 5 that can be made, with no repeats allowed and at least one character being a symbol, is:

5 * (10 * 26 * 5 * 5 * 5)

Simplifying the expression, we get:

Answer:

216 mi^3

Step-by-step explanation:

First of all you need to find the area of the base (or top, they are the same)

It is a right-angled triangle, you can simply calculate the area of the base by

A = 6*8/2 = 24 mi^2

The volume of prism is (base area)*height

volume = 24*9 = 216 mi^3

10 is redundant anyway

Answer: the volume of the prism is 62.35 mi cube

Step-by-step explanation:

so first we will find the area of triangular base of the prism, using heron formula.

and s(semi-perimeter)= a+b+c/2= 6+8+10/2= 24/2=12

Area of triangle= A = sqrt [s(s-a)(s-b)(s-c)] = sqrt {12*(12-6)(12-8)(12-10)} = sqrt {6*4*2} = sqrt (48)= 6.92 mi square

Volume = Area x Height

V= 6.92 x 9 = 62.35 mi cube.

Thus, the height of the cylinder for the given volume and radius is found to be 10 ft.

Objects in three dimensions are represented by solid shapes. Search the area! Solid shapes include any other three-dimensional object, such as a laptop, phone, ice cream cone, balls, etc.

On a three-dimensional plane, a cylinder is a solid shape. It maintains a set spacing between two circular, parallel bases that are connected by a curved surface (like a tube).

Given that:

The formula for the volume of cylinder V:

V = πr²h

Put the values:

502 = 3.14*4²*h

502 = 3.14*16*h

Find the missing dimension of the given solid.

The figure is attached.

There are 32 quarters, 225 dimes, and 53 nickels in the vending machine.

Let's denote the number of nickels by N, the number of dimes by D, and the number of quarters by Q.

From the first sentence, we know that:

N + D + Q = 292 (total number of coins)

From the second sentence, we know that:

D = 3(N + Q) (the number of dimes is three times the number of nickels and quarters together)

From the third sentence, we know that:

0.05N + 0.1D + 0.25Q = 29.95 (total value of the coins is $29.95)

Now we can substitute the second equation into the third equation to get:

0.05N + 0.1(3(N + Q)) + 0.25Q = 29.95

0.05N + 0.3N + 0.1Q + 0.25Q = 29.95

0.35N + 0.35Q = 29.95

N + Q = 85

We can now substitute this last equation into the first equation to get:

N + D + Q = 292

N + D + 85 = 292

N + D = 207

We can substitute the second equation into this last equation to get:

N + 3(N + Q) = 207

4N + 3Q = 207

We can now solve the system of equations consisting of the last two equations we derived:

N + Q = 85

4N + 3Q = 207

Multiplying the first equation by 4 and subtracting it from the second equation:

4N + 3Q - 4(N + Q) = 207 - 4*85

-N = -53

N = 53

Substituting this value into the equation N + Q = 85:

53 + Q = 85

Q = 32

Finally, we can use the equation D = 3(N + Q) from earlier to find the value of D:

D = 3(N + Q)

D = 3(53 + 32)

D = 225

Therefore, the vending machine contains 53 nickels, 225 dimes, and 32 quarters.

The mean of the data set is 25, the median is 25, the range is 20, the variance is 20, and the standard deviation is 4.47.

Given the dataset:

x = 30, 20, 35, 25, 15

N = 5

Mean of the data set is the average of the dataset. To find the average, we add up all the numbers and divide by the total number of values:

Mean (Xbar) = (30 + 20 + 35 + 25 + 15) / 5 = 25

Median is the number that fall at the middle of the dataset. To find the median of the data set, we need to arrange the numbers in order from smallest to largest:

15, 20, 25, 30, 35

The median is the middle number, which is 25 in this case.

Range of the data set can be calculated by subtract the smallest value from the largest value:

Range = 35 - 15 = 20

Standard Deviation and Variance

First find the deviations of each value from the mean:

(x - Xbar) = d

30 - 25 = 5

20 - 25 = -5

35 - 25 = 10

25 - 25 = 0

15 - 25 = -10

To find the variance, we square each deviation, add them up, and divide by the number of values:

Variance = d²/N

               = (5² + (-5)² + 10² + 0² + (-10)²) / 5

               = 100/5 = 20

To find the standard deviation, we take the square root of the variance:

Standard Deviation = sqrt(variance)

                                 = sqrt(20)
