The measure of a central angle in a regular hexagon where each interior angle is 60° is also 60°.

If each interior angle equals 60° in a polygon, then we know that the polygon is a regular hexagon. In a regular polygon, all angles are congruent, so the measure of each interior angle of a regular hexagon is 60°.

Now, to find the measure of a central angle of the hexagon, we can use the formula:

measure of central angle = 360° / number of sides

For a hexagon, the number of sides is 6, so:

measure of central angle = 360° / 6 = 60°

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry and in the given parallelogram the required value of x is 3 units.

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

In a parallelogram, the diagonals are split in half while the opposite sides are equal.

In a rhombus, all four sides are equal and the diagonals intersect at 90 degrees.

So, a parallelogram's diagonals cut each other in half.

Hence, WC = CY.

This is:

2x + 5 = 3x + 2

Take away 2x from each side:

5 = 3x - 2x + 2

The probability that the moderate number of moths in 60 traps is more significant than 0.4 is approximately 0.9738 or 97.38%.

(a).

The mean number of moths =  60 traps

Now, the properties of normal distribution and central limit theorem are used.

mean of the individual moth counts = 0.5.

The standard deviation = the Standard deviation of the individual moth counts, divided by the square root of the sample size.

standard deviation = (0.7 / [tex]\sqrt{60}[/tex])

standard deviation = 0.0905

the mean number of moths and standard deviation of the average number of moths in 60 traps are 0.5 and 0.0905.

(b) .

By using the central limit theorem

The average number of moths in 60 traps = 0.4

The z-score formula is to be calculated by using:

Z = (sample mean - population mean) / (standard deviation/sqrt (sample size))

Substituting the given values, we have:

Z = (0.4 - 0.5) / (0.7 / sqrt(60))

Z = -1.94

The probability of a Z-score greater than -1.94 is approximately 0.9738.

Hence, we can conclude that the probability that the average number of moths in 60 traps is greater than 0.4 is approximately 0.9738.

You kayak 140 feet further in 5 minutes going downstream than you do in 5 minutes going upstream.

Speed is determined by dividing the distance traveled by the time taken to travel it. It gives the distance traveled and the amount of time it took to travel that distance.

Speed is directly Proportional to Distance and Inversely proportional to Time. Hence,

Distance = Speed X Time.

Given: You paddle a kayak 168 feet up a river every two minutes.

Hence, 168/2 = 84 feet per minute.

Therefore you go up  84 feet in one minute.

You reach 84*5 = 420 feet in 5 minutes.

Given: As you paddle back down the river, you cover 56 feet every 30 seconds.

Speed is determined by distance traveled divided by time, therefore when traveling downward, 56/0.5 equals 112 feet per minute.

In one minute, you descend by 112 feet.

You descend 560 feet in 5 minutes, or 5*(112) feet.

As a result, you will move on 140 feet (560 - 420)=140 feet further .

The area of the figure composed of the square and four semicircles is approximately 242.4 square units.

A semicircle is a two-dimensional geometric shape that is half of a circle. It is formed by drawing a diameter of a circle and then drawing the arc that connects the two endpoints of the diameter. The diameter divides the circle into two equal parts, each of which is a semicircle.

A semicircle has several important properties, including:

It has one straight side, which is the diameter of the circle.

The other side is curved, and it is a half-circle.

The radius of the semicircle is equal to half the diameter of the circle.

The circumference of a semicircle is half the circumference of the circle.

The area of a semicircle is half the area of the circle.

Semicircles are used in many applications of geometry and trigonometry, including in the study of angles, arcs, and circles. They are also used in architecture and engineering to design buildings, bridges, and other structures that have semicircular features.

In addition to being a geometric shape, a semicircle can also refer to a half-circle that is used as a decorative element or design motif. Semicircles are often used in art, architecture, and graphic design to create visually interesting patterns and compositions.

To find the area of the figure composed of a square and four semicircles, we need to first find the area of the square and the area of the four semicircles. Then, we can subtract the area of the four semicircles from the area of the square to get the total area of the figure.

The area of the square is simply the side length squared, so in this case it is:

Area of square = (22)^2 = 484 square units

The diameter of each semicircle is equal to the side length of the square, so the radius is half of that or 11 units. Therefore, the area of each semicircle is:

Area of semicircle = (1/2) * π * r^2 = (1/2) * π * 11^2 = 60.4 square units

Since there are four semicircles, the total area of the four semicircles is:

Total area of semicircles = 4 * Area of semicircle = 4 * 60.4 = 241.6 square units

To get the area of the entire figure, we need to subtract the area of the four semicircles from the area of the square:

Area of figure = Area of square - Total area of semicircles

Area of figure = 484 - 241.6 = 242.4 square units

Rounding this to the nearest tenth gives:

Area of figure = 242.4 (rounded to the nearest tenth)

Therefore, the area of the figure composed of the square and four semicircles is approximately 242.4 square units.

The probability that he would have done at least this well if he had no ESP is 0.4335,

The probability of a man correctly predicting the outcome of a coin flip without having extrasensory perception (ESP) can be calculated by using probability theory.

In this case, we can calculate the probability of correctly predicting 16 or more coin flips out of 22, given that the man has no ESP. To do this, we first need to calculate the probability of correctly predicting each coin flip individually. Since each coin flip is an independent event, the probability of correctly predicting each coin flip is 0.5, or 50%.

Therefore, the probability of correctly predicting 16 or more coin flips out of 22 can be calculated as the sum of the probabilities of correctly predicting each coin flip, multiplied by the number of ways in which 16 or more coin flips can be correctly predicted. This can be expressed as

=> P(x ≥ 16) = 0.5²² x C(22, 16) + 0.5²² x C(22, 17) +…+ 0.5²² x C(22, 22),

where C is the combination operator.

Using this formula, the probability of correctly predicting 16 or more coin flips out of 22 without having ESP is 0.4335, meaning that it is highly unlikely that the man has ESP
