A surveyor needs to determine the height of a
large grain silo. He positions his transit 65 m from
the silo and records an angle of elevation of 52º.
If the height of the transit is 1.7 m, determine the
height of the silo, to the nearest metre.

5 meters is equal to 16.4042 feet.

The metre to foot formula is a mathematical expression that converts length measurements from metres to feet.

Metre is the SI unit of measurement for both length and distance.

The meter is denoted by "m".

It is denoted by the letter "ft."

To convert 5 meters (m) to feet,

Multiply the given value meters by 3.28084,

As we know that,

One meter is nearly equal to 3.28084 feet.

Therefore,

5 meters multiplied by 3.28084 gives us:

5 meters x 3.28084 = 16.4042 feet

(rounded to four decimal places)

So, 5 meters is nearly equal to 16.4042 feet.

The angle addition postulate states that if two angles share a common vertex and a common angle, forming a combination, the larger angle will be given by the sum of the smaller angles.

The entire circumference has an angle measure of 360º, while the arc EH has an angle measure of 130º, hence the length of arc FGE is obtained as follows:

To calculate the standard deviation of the sampling distribution of p-hat, the answer will be 59 students.

By calculating,

600/10=60 and 59 students which is less than 10% of the population.

A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a given random-sample-based statistic. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.

Because they offer a significant simplification before drawing conclusions using statistics, sampling distributions are crucial in the field. They enable analytical decisions to be made based on the probability distribution of a statistic rather than the combined probability distribution of all the individual sample values

The child is most likely operating at visualization level of van hiele's. The solution has been obtained by using the Van Hiele model.

What is Van Hiele model?

The van Hiele theory explains how children pick up geometry. It makes the claim that there are five different degrees of geometric thinking: visualisation, analysis, abstraction, formal deduction, and rigour. Every level has a unique lingo and set of symbols. The levels are progressed through "step by step" by the students.

We are given that a child tells that square has 4 sides and 4 angles by seeing the quadrilateral.

From this, we get that the child is operating at the visualization level of van hiele's because by looking at a figure he tells the number of sides and angles.

Variance in statistics is the squared difference between a random variable's expected value and its mean value.

Data points' variance from the mean is a measure of how they vary. A variance, according to Layman, is a measurement of how widely apart a set of data (numbers) are from their mean (average) value.

Finding the expected difference of deviation from the actual number is what is meant by variance. As a result, variance is influenced by the data set's standard deviation.

Data is more dispersed from its mean the higher the variance value, and less dispersed from mean if the variance value is low or minimal. As a result, it is referred to as a measure of data spread from mean.

Let's represent the area of the lawn with "x" (in square meters).

Maria charged $135 plus $9.55 per square meter, so her total earnings can be expressed as:

Total earnings = $135 + $9.55 x

We know that Maria was paid $1854, so we can set up an equation and solve for x:

$1854 = $135 + $9.55 x

Subtracting $135 from both sides:

$1719 = $9.55 x

Dividing both sides by $9.55:

x = 180

Therefore, the area of the lawn is 180 square meters.

The length opposite the angle is the vertical distance from the x-axis on the graph. Because sin (π/3) = opposite/hypotenuse = opposite/1;

Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.

Here, The angle π/3 forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).

Also, the terminal side intersect the circle at (x, y). Thus;

sin (π/3) = opposite/hypotenuse = opposite/1

8inch can be converted into centimeters (cm) using the conversion factor of 1 inch equals 2.54 centimeters.  it's essential to use the appropriate conversion factor and ensure that the units cancel out correctly to arrive at the desired result.

Since 8 is a unit of inches, we can simply multiply 8 by the conversion factor of 2.54 cm/inch to get the equivalent measurement in centimeters.

So, the conversion can be done as follows:

8 inches x 2.54 cm/inch = 20.32 cm

(a) There are 220 different boxed sets possible.

(b) here are 2184 different schedules possible for Rashid's vacation.

(a)

To calculate the number of different boxed sets possible, use the combination formula. In this case, choose 9 albums out of 12, and the order of the albums in the boxed set doesn't matter.

The number of combinations of n items taken r at a time is given by the formula:

C(n, r) = n! / (r! × (n - r)!)

In this case, to find C(12, 9):

C(12, 9) = 12! / (9! × (12 - 9)!)

C(12, 9) = 12! / (9! × 3!)

C(12, 9) = (12 × 11 × 10) / (3 × 2 × 1)

C(12, 9) = 220

(b)

To calculate the number of different schedules Rashid can make for his vacation, count the number of ways chosen 3 cities out of 14 for each day of the week.

For Monday, choose one city out of 14.

For Tuesday, choose one city out of the remaining 13 .

For Wednesday, choose one city out of the remaining 12 .
