Answer: Each lateral face would have an area measuring 11.32 square metres.

(2) The total lateral area is 40.88 square metres.

Step-by-step explanation: A three-sided triangular prism as stated in the question would have triangular faces on all sides and since the one in the question is described as a hollow triangular pyramid, we can safely conclude that each surface is a flat/plane shape. Also, each of the triangular surfaces has a base length of 4 metres and a slant height of 6 metres. The surface area is given as

Area of a triangle =  1/2 * base * height

However, the height given is the slant height. Therefore to calculate the vertical height, we shall apply the Pythagoras' theorem, which means the triangular surface would have to be divided into two halves by a perpendicular line that splits the base length into two equal sides. This results in a right angled triangle with the hypotenuse measuring 6 metres and one of the two other sides measuring 2 metres. We now have

AC² = BC² + AB²

Where AC is the hypotenuse 6, BC is one of the other sides 2, and AB is the unknown (slant height).

6² = 2² + AB²

36 = 4 + AB²

Subtract 4 from both sides of the equation

32 = AB²

Add the square root sign to both sides of the equation

√32 = √AB²

5.66 = AB

The area of the triangular surface now becomes;

Area = 1/2*base*height

Area = 1/2 x (4 x 5.66)

Area = 1/2 x 22.64

Area = 11.32 metres²

The total of all three surfaces would be derived as

Surface areas = 11.32 x 3

Surface areas = 33.96 metres²

For the base area, with all three sides measuring 4 metres each, the area would be derived but first we need to calculate the slant height first.

With a line drawn perpendicular to one of the sides, we now have a right angled triangle with the hypotenuse as 4, one of the sides as 2, and the other side unknown (slant height).

AC² = AB² + BC²

4² = 2² + BC²

16 = 4 + BC²

Subtract 4 from both sides of the equation

12 = BC²

Add the square root sign to both sides of the equation

√12 = √BC²

3.46 = BC

The area of the base triangle now becomes;

Area = 1/2*base*height

Area = 1/2 x (4 x 3.46)

Area = 1/2 x (13.84)

Area = 6.92

The total lateral area would now become

Lateral area = Surface area + Base area

Lateral area = 33.96 + 6.92

Lateral area = 40.88 metres²

Step-by-step explanation:

Joy's approach to sampling art at the gallery, by examining 2 pieces per artist, can be representative if the selections span the artists' exhibited range. However, the representativeness might be limited if artists have a wide variety of styles or themes not captured by just two pieces.

Joy, by examining 2 pieces of art by each artist at the art show, attempts a representative sampling of the gallery's overall offerings. Whether this approach yields a representative sample depends on a few key factors. Primarily, the diversity and range of the artists' works on display must be considered. If each artist displays a wide variety of work and Joy's selections span this variety, her sample could offer a fair representation of the gallery's exhibition. However, if the artists have a vast body of work with significant variations in style, theme, or period not captured by just two pieces per artist, Joy's sample may not accurately represent the entire collection.

Furthermore, the extent to which the selected works reflect the artists’ core themes or periods plays a critical role in determining representativeness. Assuming each artist's work on display has an equal chance of being selected and Joy chooses pieces that span the artists' exhibited range, the sample can be somewhat representative. Nonetheless, a truly comprehensive view would likely require examining a greater number or a more strategically chosen set of artworks.

Joy’s examination provides valuable insights, but for a truly representative view of the gallery, additional observations or data would be beneficial.

Let’s explore the concept of representative samples in the context of Joy’s art gallery experience.

1. Understanding Representative Samples:

o A representative sample is a subset of a larger population that accurately reflects the characteristics of the entire population. In this case, the population consists of all the art pieces displayed in the gallery.

o When we say a sample is “representative,” it means that the selected pieces adequately capture the diversity and essence of the entire collection.

2. Joy’s Situation:

o Joy closely examined 2 pieces of art by each artist. Since each artist had an equal number of pieces on display, Joy effectively observed a balanced representation of the artists’ work.

o By examining multiple pieces from each artist, Joy has a better chance of encountering a variety of styles, themes, and techniques.

3. Likelihood of Representativeness:

o Given that Joy looked at 2 pieces from each artist, we can consider this sample as potentially representative.

o However, there are a few factors to consider:

 Artistic Diversity: If the artists’ styles are vastly different, the sample may not fully represent the entire gallery’s range.

 Number of Artists: If there are only a few artists in total, the sample might be less representative.

 Gallery Size: The larger the gallery, the more challenging it is to capture full representativeness with a limited sample.

4. Conclusion:

o While Joy’s sample is a good start, it’s essential to recognize its limitations.

o To determine true representativeness, we’d need more information about the total number of artists, the overall collection size, and the diversity of artistic approaches.

In summary, Joy’s examination provides valuable insights, but for a truly representative view of the gallery, additional observations or data would be beneficial.

Answer: 12km

Step-by-step explanation:

2cm=3km

2x4=8

3x4=12

Final answer:

The real-life distance between two points that are 8 cm apart on a map, with a map scale of 2 cm = 3 km, is 12 km. This is calculated using a proportion based on the given scale ratio.

Explanation:

The question asks how to calculate the real-life distance between two points that are 8 cm apart on a map, given that 2 cm on the map are equal to 3 km in real life. To solve this, we can use a proportion where 2 cm on the map corresponds to 3 km of actual distance. The scale ratio is therefore 2 cm : 3 km. If the points are 8 cm apart on the map, we set up the proportion as follows:

We cross multiply to find x:

So, the real-life distance between the two points is 12 km.

The relationship between angles ∠a and ∠b is they are complementary angles.

Given a figure.

Here, two lines are crossed to each other such that the angles between each of the cross is 90 degrees.

So the angle between the lines BX and XC which forms at X is a right angle or 90 degrees.

So,

m∠BXC = 90°

Now, ∠BXC is the sum of the angles ∠BXY and ∠YXC.

From the figure,

∠BXY = ∠a and ∠YXC = ∠b.

So,

m∠BXY + m∠YXC = 90°

∠a + ∠b = 90°

When the sum of two angles is 90°, then they are complementary angles.

Hence, ∠a and ∠b are complementary angles, which is the option B.

A pizza with a diameter of 13 inches is cut into 12 equal slices. Jayden eats 1/3 of the pizza, representing an area of ____ square inches. Carson eats 5 slices of pizza, representing an area of ____ square inches.

Answer:

Jayden consume pizza with an area of 44.2498 inches squared.

Carsen consumes pizza with an area of 55.3125 inches squared

Step-by-step explanation:

Diameter is 13 inches,

Radius is diameter divided by 2

Radius = 13/2 = 6.5 inches

Area = pi times radius squared

Area = 3.142 x 6.5^2 = 132.7495.

For jayden, 1/3 of this will be

1/3 x 132.7945 = 44.2498 inches squared.

For carsen, the 12 slice of pizza will each have an area of 132.7945/12 = 11.0625 inches squared,

5 of those slices will have area of 5 x 11.0625 = 55.3125 inches squared.

Answer:

13.5% probability of a meerkat living between 12.3 and 14.2 years.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 10.4

Standard deviation = 1.9

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above the mean.

Between 12.3 and 14.2 years.

12.3 = 10.4 + 1.9

So 12.3 is one standard deviation above the mean.

50% of the measures are above the mean. Of those, 68% are within 1 standard deviation of the mean.

14.2 = 10.4 + 2*1.9

So 14.2 is two standard deviations above the mean.

50% of the measures are above the mean. Of those, 95% are within 2 standard deviation of the mean.

0.5*0.95 - 0.5*0.68 = 0.135

13.5% probability of a meerkat living between 12.3 and 14.2 years.
