Evaluate: 39/y + 5y if x = 3 and y = 5.

The surface area of the composite solid is 286 square feet.

To calculate the surface area of this composite solid,

Find the areas of each individual shape and then add them up.

The rectangular prism has a surface area of,

2(11x2 + 11x2 + 2x11)

= 2(22 + 22 + 22)

= 2(66)

= 132 square feet.

The square pyramid has a base area of,

11x11 = 121 square feet.

The area of each triangular side can be found using the formula,

1/2 x base x height.

The base of each triangle is 11 feet (since it is the same as the length of the base of the pyramid), and the height of each triangle is 7 feet.
So each triangle has an area of 1/2 x 11 x 7 = 38.5 square feet.

There are four triangular sides, so the total area of the triangular sides is 4 x 38.5 = 154 square feet.

Adding the surface area of the rectangular prism and the square pyramid, we get

132 + 154 = 286 square feet.

Therefore, the correct answer is 286 square feet.

The mass of the marble lifter by a sculpture is 0.0306 kg.

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

We know the volume of a cuboid is (length×width×height).

Therefore, The volume of this cuboid is (1×0.6×0.3) = 0.18 m³.

The marble has a density of 2.7g/cm which is equivalent to 0.17kg/meter.

We know Mass = volume×density.

Therefore, The mass of the marble is 0.17×10.18 kg.

= 0.0306 kg.

The mean of the team’s distances is 3.75 miles. The median of the team’s distances is 3.5 miles.

To find the mean of the distances run by the Kennedy High School cross-country running team, we will first add up all the distances and then divide by the number of distances. The distances ran by the Kennedy High School cross-country running team are:

3.5 miles, 2.5 miles, 4 miles, 3.25 miles, 3 miles, 4 miles, and 6 miles adding up these distances, we get:

3.5 + 2.5 + 4 + 3.25 + 3 + 4 + 6 = 26.25

So the sum of the distances is 26.25 miles. Now, to find the mean, we will divide by the number of distances, which is 7. Therefore, the mean of the distances is: Mean = Sum of distances / Number of distances

Mean = 26.25 / 7

Mean = 3.75 miles

To find the median of the distances run by the team, we will first arrange the distances in order from smallest to largest:2.5 miles, 3 miles, 3.25 miles, 3.5 miles, 4 miles, 4 miles, 6 miles

Now, we will find the middle value. Since there are 7 distances, the middle value will be the 4th value. Counting from the left, the 4th value is 3.5 miles. Therefore, the median of the distances ran by the team is 3.5 miles.

Answer:

Step-by-step explanation:

The probability of selecting a number less than 10 given that it is less than 13 is 5/8.

To find the probability of selecting a number less than 10 given that it is less than 13, we first need to determine the favorable outcomes and the total number of outcomes.

The given sample space is: 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.

Favorable outcomes (numbers less than 10): 5, 6, 7, 8, 9.

Total number of outcomes (numbers less than 13): 5, 6, 7, 8, 9, 10, 11, 12.

To find the probability, we divide the number of favorable outcomes by the total number of outcomes:

P(less than 10 | less than 13) = Number of favorable outcomes / Total number of outcomes

P(less than 10 | less than 13) = 5 / 8

Simplifying the fraction, we get:

P(less than 10 | less than 13) = 5/8

Therefore, the probability of selecting a number less than 10 given that it is less than 13 is 5/8.

No simple graph with six vertices and the above degrees exists.Graph with 6 vertices with degrees 0, 1, 2, 3, 4, 5.For a simple graph, the sum of the degrees of all vertices must be even.The resulting graph is also an Eulerian graph.

a) There exists a simple graph with 6 vertices, whose degrees are 2,2,2,3,4,4.

The given degrees 2, 2, 2, 3, 4, 4 sum up to 17, which is an odd number.

A simple graph with six vertices whose degrees are all even must have a sum of degrees of 6 × 2 = 12, which is even.

Therefore, no simple graph with six vertices and the above degrees exists.

b) There exists a simple graph with 6 vertices whose degrees are 0, 1, 2, 3, 4, 5.

The sum of degrees of vertices in a graph is twice the number of edges, so there are a total of 2 × (0 + 1 + 2 + 3 + 4 + 5) = 30 degrees in this graph.

For the graph to be simple, there can be a maximum of one vertex of degree 5 and one vertex of degree 0.

The graph may be formed by starting with a vertex of degree 5, and joining it to the vertices of degrees 4, 3, 2, 1, and 0 in turn.

The resulting graph is shown in the following figure:Graph with 6 vertices with degrees 0, 1, 2, 3, 4, 5

c) There exists a simple graph with degrees 1, 2, 2, 3.

The degree sequence has an odd sum, so no simple graph can have that degree sequence.

This is because, for a simple graph, the sum of the degrees of all vertices must be even.

d) A graph containing an Eulerian circuit is called an Eulerian graph.

If 61 and 62 Are Eulerian graph, and we add the following edges between them, then the resulting graph is Eulerian:6For 6 to be added as an edge to both 1 and 2, they must have even degree.

Since they were originally Eulerian graphs, each vertex already had even degree.

After 6 is added as an edge to both vertices, it becomes possible to start at one vertex and traverse the graph by using edges that have not been used before and eventually return to the starting vertex.

Hence, the resulting graph is also an Eulerian graph.

To obtain a sense of predictability, Kelly suggests engaging in hypothesis testing (d).

Kelly's suggestion aligns with the scientific method, which involves formulating hypotheses and testing them to make predictions and gain a sense of predictability. Hypothesis testing is a systematic approach that allows us to evaluate the validity of a proposed explanation or theory.

Template matching (a) refers to a process where incoming information is compared to stored templates or patterns to identify similarities. While it may be useful in certain contexts, it does not directly address the concept of predictability or the systematic evaluation of hypotheses.

Theory construction (b) involves the development of explanatory frameworks that describe and explain phenomena. While theory construction can contribute to predictability by providing overarching explanations, it is typically preceded by hypothesis testing to validate or refine the proposed theories.

Scientific discovery (c) refers to the process of making new observations, uncovering new phenomena, or formulating novel theories. While scientific discovery plays a crucial role in expanding knowledge and understanding, it is often followed by hypothesis testing to validate or refine the newly discovered information.

Therefore, Kelly's suggestion of engaging in hypothesis testing (d) is aimed at obtaining a sense of predictability by systematically evaluating and testing hypotheses to make reliable predictions about future outcomes or observations.

Answer:

0.15 as a fraction in simplest form is 3/20.

To break even, the soft drink machine needs to sell approximately 38.46 cans of soda each week. Since you can't sell a fraction of a can, you would need to round up to the nearest whole number.

To break even, the total revenue from selling cans of soda should equal the total cost. The total revenue can be calculated by multiplying the number of cans sold (x) by the price per soda ($0.75). So the total revenue is 0.75x.
The total cost includes the cost of each soda ($0.10) multiplied by the number of cans sold (x), plus the weekly fixed cost of maintaining the soda machine ($25). So the total cost is 0.10x + 25.
To find the break-even point, we need to set the total revenue equal to the total cost and solve for x:
0.75x = 0.10x + 25
First, subtract 0.10x from both sides of the equation:
0.75x - 0.10x = 0.10x + 25 - 0.10x
0.65x = 25
Then, divide both sides of the equation by 0.65:
x = 25 / 0.65
x ≈ 38.46
Therefore, to break even, the soft drink machine needs to sell approximately 38.46 cans of soda each week. Since you can't sell a fraction of a can, you would need to round up to the nearest whole number. So, you would need to sell at least 39 cans of soda each week to break even.
