Hence, the correct option is b) statistic .

Answer: 3cm

Step-by-step explanation:

The volume of a cube formula is x^3 where x is any of the sides. All sides are the same length because it is a cube. If x^3=27 then x must equal 3 as 3x3x3=27.

Answer:

3

Step-by-step explanation:

Since you know that the shape is a cube, that means that all the sides are the same length.

The factors of 27 are 1 & 27, 3 & 9.

1 & 27 won't work for this problem so you use 3 & 9.

9 is divisible by 3 so what you would get is 3 x 3 x 3 which then equals 27.

There are approximately 63,063 ways to choose 16 croissants from the selection of 6 different types offered by the croissant shop.

To find the number of ways to choose 16 croissants from a selection of 6 different types, we can use the concept of combinations.

The formula for combinations is:

nCr = n! / (r! * (n-r)!)

where n is the total number of items to choose from, and r is the number of items to choose.

In this case, there are 6 different types of croissants, and we want to choose 16 of them. Therefore, we can calculate the number of ways to choose 16 croissants as follows:

6C16 = 6! / (16! * (6-16)!) = 6! / (16! * (-10)!) = 6! / (16! * 10!) ≈ 63,063

To determine if it would be unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name, we can use the concept of standard deviation and z-scores.

First, we need to calculate the z-score, which measures how many standard deviations an observation is from the mean. The formula for calculating the z-score is:

z = (x - μ) / σ

where

z = (5 - 9.3) / 0.99

z = -4.394

Next, we can consult a standard normal distribution table or use statistical software to find the corresponding percentile associated with the z-score. This percentile represents the probability of randomly selecting a group of 12 people with fewer than 5 recognizing the Yummy brand name.

In this case, the z-score of -4.394 corresponds to an extremely low percentile, close to 0.

The exact probability can be determined using the z-score and the standard normal distribution table.

Since the probability is extremely low, it would be considered unusual to randomly select 12 people and find that fewer than 5 recognize the Yummy brand name.

However, it's important to note that the definition of "unusual" may vary depending on the specific criteria or threshold chosen.

In statistical terms, a common threshold for defining unusual events is a significance level of 5% (or 0.05). If the probability of observing the event is lower than the significance level, it is considered unusual.

Let's denote the ages of the two remaining men as x and x + 3 (since one is 3 years older than the other).

We know that the average age of 6 men is 35 years. So, the sum of their ages is 6 * 35 = 210 years.

We also know that the average age of four of them is 32 years. So, the sum of their ages is 4 * 32 = 128 years.

To find the sum of the ages of the two remaining men, we subtract the sum of the ages of the four men from the sum of the ages of all six men:

210 - 128 = 82 years.

Now, we can set up an equation to solve for the ages of the remaining two men:

x + (x + 3) = 82.

Combining like terms, we get:

2x + 3 = 82.

Subtracting 3 from both sides:

2x = 79.

Dividing both sides by 2:

x = 39.5.

So, one of the remaining men is 39.5 years old, and the other is 39.5 + 3 = 42.5 years old.

All chiral D-sugars rotate plane-polarized in a direction that cannot be predicted but must be determined experimentally. So, option D is correct.

Chiral D-sugar is a form of molecule with a chiral center that is a member of the carbohydrate class.

Because they are chiral D-sugars, it is impossible to determine which way they will rotate in advance.

The molecule's particular arrangement determines the direction of spin, and rotational intensity is measured in degrees. When both enantiomers of a chiral D-sugar are present in equal amounts (i.e., when it is a racemic combination), the sugar is optically inactive and does not rotate plane-polarized light.

In the vector space (V, ⊕, ☉), where V = R², the sum of (6,-5)⊕(-2,-8) is (7,-16), the scalar multiple of -9☉(6,-5) is (-51,42), the zero vector is (3,3), and the additive inverse of (x, y) is (-x-3, -y+3).

To find the sum of (6,-5)⊕(-2,-8), we add the corresponding components of the vectors and apply the defined addition operation:

(6,-5)⊕(-2,-8) = (6 + (-2) + 3, -5 + (-8) - 3) = (7, -16)

Next, to find the scalar multiple of -9☉(6,-5), we multiply each component of the vector by -9 and apply the defined scalar multiplication operation:

-9☉(6,-5) = (-9(6) + 3(-9) - 3, -9(-5) - 3(-9) + 3) = (-51, 42)

The zero vector, denoted as 0v, is obtained by applying the addition operation with the additive identity (0,0) to any vector:

0v = (0,0)⊕(6,-5) = (0 + 6 + 3, 0 - 5 - 3) = (3,3)

Finally, to find the additive inverse of (x, y), we negate each component of the vector and apply the addition operation with the additive identity:

The equation of a line y=2x+8.

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in the value of y on the vertical axis/change in the value of x on the horizontal axis

Looking at the given line,

y = 2x + 7

Compared with the slope-intercept equation,

Slope, m = 2

If a line is parallel to another line, it means that both lines have equal or the same slope. This means that the slope of the line passing through the point (-2, 4) is 2

Substituting m= 2, y = 4 and x = -2 into the equation, y = mx + c , it becomes

4 = 2 × - 2 + c

4 = - 4 + c

c = 4 + 4 = 8

The equation becomes y=2x+8.

The width of the runway is approximately 28.3 feet. The length of the runway in feet is Length = 3.75 miles * 5,280 feet/mile

The new runway being constructed on the east side of the estate, which extends to the ranch house, is 3.75 miles long and covers a total area of 5.6 acres. To determine the width of the runway in feet, we can use the following information:

1 acre = 43,560 square feet

First, let's convert the length of the runway from miles to feet:

1 mile = 5,280 feet

Therefore, the length of the runway in feet is:

Length = 3.75 miles * 5,280 feet/mile

Next, let's calculate the width of the runway using the area and length:

Area = Length * Width

Since we are given the area in acres, we need to convert it to square feet:

Area = 5.6 acres * 43,560 square feet/acre

Now, we can solve for the width:

Width = Area / Length

Substituting the values we have:

Width = (5.6 acres * 43,560 square feet/acre) / (3.75 miles * 5,280 feet/mile)

Simplifying the expression:

Width = (5.6 * 43,560) / (3.75 * 5,280) feet

Calculating the value:

Width ≈ 560,784 / 19,800 feet

Width ≈ 28.3 feet

Therefore, the width of the runway is approximately **28.3 feet**.

The statement that is true about the number of hours of daylight is: "the number of hours of daylight varies depending on the latitude of the observer."

Hence, option (a) is the correct choice.

Day length will be roughly 12 hours at latitude 0° (the Equator). The Equator region has a steady 12 hour day light all year.

Day duration can be observed to extend to 24 hours or reduce to zero if latitude increases to 80° (polar circles - north or south) (depending on time of year).

The quantity of daylight received by an observer is determined by their latitude and the season.

The number of hours of daylight changes the greatest near the equator, whereas it varies the least towards higher latitudes.

The number of daylight hours covers the hours between dawn and twilight as well as the hours from sunrise to sunset.
