Step-by-step explanation:

The largest number she uses for a random number is 100. The smallest is one.

A wand comes up 47% of the time. Since it is the most common event, you could put it first and let the range be 1 to 47 inclusive.

But any range will work as long as there are 47 numbers between the beginning and the end, like 30 and 77. This looks like it won't work, but it will. It's just a little awkward. One of the other 2 might have to be split.

The Amulet can go from 78 to 100 which takes up 22 numbers. The other 13 can go before the 30

Step-by-step explanation:

Part A is correct

Part B

student A solved the system correctly

Part C

student B  made the error from step 3 to step 4 , that is

step 3 : 3x - 5x + 150 = 114

step 4 : - 2x + 150 = 114 ( should be - 2x not 2x was the error made )

step 5 : - 2x = 114 - 150 = - 36

step 6 : - 2x = - 36 ( divide both sides by - 2 )

                x = 18

substitute x = 18 into y = - x + 30 ( from step 1 )

y = - 18 + 30 = 12

Answer : (18, 12 ) which is the answer student A obtained correctly

The area of the square with a side length of 3.1 meters is 9.61 square meters.

To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.

Area of a square = side length × side length

Substituting the given side length into the formula:

Area = 3.1 m × 3.1 m

To perform the calculation:

Area = 9.61 m²

It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.

Remember, to find the area of any square, you simply need to multiply the length of one side by itself.

The area of the square with a side length of 3.1 meters is 9.61 square meters.

A more modern explanation would be, "Parallel lines are two lines within a given plane that never intersect."

Two lines on a sphere are an illustration that defies the notion of parallel lines. Meridians are the name given to longitude lines on spheres like the Earth.

Meridians are lines that run parallel to one another from the North Pole to the South Pole. However, if we take into account two meridian lines, they will cross at the North and South Poles. Two lines that are originally parallel will, therefore, eventually intersect at the poles on a sphere, defying the notion of parallel lines.

We can change the original definition of parallel lines to read, "Parallel lines are two lines that do not intersect within a given plane."

This adjustment accounts for the fact that lines can exist in many geometrical contexts, such as on a sphere or in three-dimensional space, where the idea of parallelism may be different. By including the phrase "within a given plane," we restrict the concept to the typical geometry seen in Euclidean geometry, where parallel lines do not meet.

A newer definition may therefore read, "Parallel lines are two lines within a given plane that never intersect." This updated definition makes clear that parallel lines must be taken into account inside a certain plane in order to maintain their validity, while also acknowledging the limitations of the idea.

The surface area of the composite shape is 328 cm².

The surface area of the composite shape is calculated as follows:

The surface area of the large cuboid:

The top and bottom faces each have an area of length x width = 14 cm x 8 cm = 112 cm².

The front and back faces each have an area of height x width = 8 cm x 8 cm = 64 cm².

The left and right faces each have an area of length x height = 14 cm x 8 cm = 112 cm².

Therefore, the total surface area of the cuboid is:

= 2(112 cm²) + 2(64 cm²) + 2(112 cm²)

= 224 cm² + 128 cm² + 224 cm²

= 576 cm²

The surface area of the large cuboid:

The top and bottom faces each have an area of length x width = 10 cm x 6 cm = 60 cm².

The front and back faces each have an area of height x width = 8 cm x 6 cm = 48 cm².

The left and right faces each have an area of length x height = 10 cm x 8 cm = 80 cm².

Therefore, the total surface area of the cuboid is:

= 2(60 cm²) + 2(48 cm²) + 2(80 cm²)

= 120 cm² + 96 cm² + 160 cm²

= 376 cm²

So, the surface area of the composite shape = 576 cm² - 376 cm² + 48 cm² + 80 cm²

The surface area of the composite shape = 328 cm²

Answer:

Daisy, Geranium, Daffodil, and Tulip.

Step-by-step explanation:

We already have two values to compare in decimal form. We can convert the others.

Tulip: 0.8333 repeating.

Daffodil: 0.79

We have 13/20 for Daisy and 3/4 for Geranium.

We can multiply the denominator and the numerator of 13/20 by 5 to get 65/100. In decimal form this would be 0.65

Now we have the value for Daisy.

Daisy: 0.65

We need to find Geranium. We can multiply both the numerator and denominator by 25 to get the decimal form. 3/4 = 75/100

Geranium: 0.75

Now that we have our values, we can order them from least to greatest.

This would give us the answer of Daisy, Geranium, Daffodil, and Tulip.

The sample space for rolling a fair eight-sided die is S = {1, 2, 3, 4, 5, 6, 7, 8}; the correct option is D

Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. The probability that an event will occur P(E) is equal to the ratio of favorable outcomes to total outcomes. The likelihood of an event occurring might range from 0 to 1. A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space. Events are the subset of possible experiment results.

Given;

An eight-sided die,

The sample space=?

Now, when eight sides die is tossed there will be 8 sample spaces that are;

1, 2, 3, 4, 5, 6, 7, 8,

Hence, S = {1, 2, 3, 4, 5, 6, 7, 8}
