The MATHCOUNTS International airport had the mean number of seconds between departure time of 43 seconds in 2001.

For given question,

In 2001 there were 738,114 departures.

As we can see, 2001 was not a leap year.

So, the number of days in 2001 = 365

We find the number of departures per day in 2001.

738,114 / 365 = 2,022.23

So, approximately 2,022 departures per day.

Now we find the number of departures in an hour.

2,022 / 24 = 84.25

This means, approximately 84 departures per hour

We know that, 1 hour = 3,600 seconds

Now we find the mean number of seconds between departure time.

3,600 / 84 = 42.8

                  ≈ 43 seconds

Therefore, the MATHCOUNTS International airport had the mean number of seconds between departure time of 43 seconds in 2001.

Given is line plot we need to find the amount of cheese used in all the recipe,

so, 3 1/2 cups are used for one time, 3 3/4 used for 6 times and 4 cups are used for 1.

So,

3 1/4 + 3 3/4 × 6 + 4

= 13/4 + 15/4 × 6 + 4

= (13 + 90 + 16) / 4

= 119 / 4

Answer:

A) 120 ft^2

Step-by-step explanation:

The total surface area is the sum of the areas of the 4 congruent triangular sides and the area of the square base.

TA = 4 * area of triangle + area of square

TA = 4 * bh/2 + s^2

TA = 4 * 6 ft * 7 ft/2 + (6 ft)^2

TA = 84 ft^2 + 36 ft^2

TA = 120 ft^2

Para compartir 7 alfajores entre 4 niños y niñas para que no quede nada, a cada niño y niña se les debe dar 7/4 alfajores

Step-by-step explanation:

Al compartir 5 alfajores, entre 3 niños y niñas, los alfajores se cortan en tres partes cada uno de manera que cada niño y niña recibe 5/3 piezas de alfajore

Luego, la pregunta es, ¿cómo se pueden compartir 7 alfajores entre 4 niñas y niños sin que quede nada?

Por el proceso de compartir ejemplos, obtenemos;

Cada alfajores debe dividirse en el número total de niños y niñas, que son cuatro piezas cada uno.

El número total de 1/4 piezas = 7 × 4 = 28 piezas de 1/4 alfajores

Cada niño y niña recibe 7 de las piezas de 1/4 alfajores

El número total de alfajores, n, compartidos entre los cuatro niños y niñas viene dado por la expresión;

n = 7 (1/4 alfajores) × 4 = 28 piezas de 1/4 alfajores

Por lo tanto, para compartir 7 alfajores entre 4 niños y niñas para que no quede nada, cada niño y niña debe recibir 7/4 alfajores.

ab⁶ is not a variable term found in the binomial expansion of \((a + b)^{8}\)as this is because, the powers must sum up to 8

A polynomial with just terms is a binomial. An illustration of a binomial is x + 2, where x and 2 are two distinct words. Additionally, in this case, x has a coefficient of 1, an exponent of 1, and a constant of 2. As a result, a binomial is a two-term algebraic statement that comprises a constant, exponents, a variable, and a coefficient.

The Binomial Expansion of \((a+b)^8\) is -

Answer:

243 m³

Step-by-step explanation:

The volume of a rectangular pyramid is given by:

\(V = \frac13lwh\)

Where

l = length = 9m

w = width = 9m

h = height = 9m

so the volume is 1/3*9*9*9 = 243 m³

Answer:

243

Step-by-step explanation:

The formula for the volume of a square-based pyramid is

\(V=\frac{lwh}{3}\)

\(l\) = length

\(w\) = width

\(h\) = height

\(V=\frac{9 \times 9 \times 9}{3}\)

\(V=\frac{729}{3}\)

\(V=243\)

Evaluating the algebraic expressions for the values given, we have:

a. -7

b. -10.

To evaluate and algebraic expression, plug in the value of the variable given and solve accordingly.

a. Given the algebraic expression, xy + 5.

If x = 2, and y = -6, then substitute x = 2 and y = -6 to evaluate the algebraic expression:

xy + 5

(2)(-6) + 5 [substitution]

= -12 + 5

Length of paper left is 5 m.

What is length?

Distance is measured by length. Length is a quantity having the dimension distance in the International System of Quantities. Most measuring systems use a base unit for length from which all other units are derived. The metre is the basic unit of length in the International System of Units (SI). The greatest extended dimension of a stationary item is typically believed to be its length. This is not always the case, as it may depend on the location of the item. Height, sometimes known as vertical length or vertical extent, and width, breadth, or depth are all words used to describe the length of a stationary object. When length is the longest dimension, width or breadth generally refer to the shorter one.

Using Marked recapature formula for estimation on population size we get,

the estimate for total population size is 1200.

Marked recaputure Method :

first step is to capture and mark a sample of individuals. The assumption behind mark-recapture methods is that the proportion of marked individuals recaptured in the second sample represents the proportion of marked individuals in the population as a whole. In algebraic terms,

R/S = M/N

where R --> second time marked

S---> size of sample second time

N --> estimate population size

M ---> Marked in start point

We have given that ,

Total marked turtles by researchers (M) = 800

Second time total sample size (S) = 300

second time marked turtles(R) = 200

we have to find out estimate for total population size .

For this , Mark -Recapture method is very efficient to calculate estimate for total population size.

putting all known values in above formula we get, R/S = N/M

=> 200/300 = 800/N

=> 800× 300 = N× 200

=> N × 200 = 240000

=> N = 240000/200

=> N = 1200

so, the estimate for total population size is 1200.

If the mean, median, and mode of a sample are all the same value, it suggests that the data is likely symmetrical and the mode is the most frequent value.

it does not necessarily imply that the researcher can be 100% sure about the population mean or that a computational error has occurred. A larger sample size may not be required solely based on the equality of mean, median, and mode in small datasets.

Explanation:

The fact that the mean, median, and mode are all the same value in a sample indicates that the data is symmetrically distributed. This symmetry suggests that the data has a balanced distribution, where values are equally distributed on both sides of the central tendency. This information can be helpful in understanding the shape of the data distribution.

However, it is important to note that the equality of mean, median, and mode does not guarantee that the researcher can be 100% certain about the population mean. The sample mean provides an estimate of the population mean, but there is always a degree of uncertainty associated with it. To make a definitive conclusion about the population mean, additional statistical techniques, such as hypothesis testing and confidence intervals, would need to be employed.

Option C, stating that a computational error must have been made, is an incorrect conclusion to draw solely based on the equality of mean, median, and mode. It is possible for these measures to coincide in certain cases, particularly when the data is symmetrically distributed.

Option D, suggesting that a larger sample must be taken, is not necessarily warranted simply because the mean, median, and mode are the same in small datasets. The equality of these measures does not inherently indicate that the data is inaccurate or that a larger sample is required. The decision to increase the sample size should be based on other considerations, such as the desired level of precision or the need to generalize the findings to the population.

Therefore, option A is the most appropriate conclusion. It acknowledges the symmetrical nature of the data while recognizing that the mean can be reported but with an understanding of the associated uncertainty.
