Answer:

Step-by-step explanation:

The correct answer is A.

In the context of this situation, the slope of -6.2 means that the temperature drops 6.2 degrees for every hour that passes. The negative sign indicates that the temperature is decreasing over time.

The y-intercept of 64 means that at hour 0 (the start of recording data), the temperature was 64 degrees. This is the initial value of the temperature, before any time has passed.

The slope and y intercept describes that

The slope applied to this situation is the temperature drops 6.2 degrees per hour. The y-intercept means at hour 0 (start of recording data), it was a temperature of 64 degrees.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have,

The line of best fit with the equation y = -6.2x + 64, where x represents the hour and y represents the temperature.

As, we know that the slope shows the rate of change of one quantity with respect to another quantity.

Here, the slope -6.2 tells us that the  temperature drops 6.2 degrees per hour.

and, the y intercept tells us that at 0 hour the temperature is 64 degree.

Answer: A square pyramid has 5 faces, 8 edges, and 5 vertices.

Step-by-step explanation:

The required answer is a square pyramid (excluding the base) has four faces. A square pyramid consists of a square base and triangular faces that meet at a common vertex.

To determine the number of faces excluding the base, we can follow these steps:

Step 1: Identify the number of triangular faces.

In a square pyramid, there are four triangular faces that connect each corner of the square base to the apex (the top vertex). These triangular faces do not include the base.

Step 2: Determine the total number of faces.

In addition to the triangular faces, we need to consider the base of the pyramid. The base is a square, and it is not counted when we exclude the base. Therefore, the number of faces excluding the base is the same as the number of triangular faces.

Step 3: Calculate the number of faces.

Since we determined that a square pyramid has four triangular faces, the square pyramid (excluding the base) has four faces.

Hence, a square pyramid (excluding the base) has four faces. A square pyramid consists of a square base and triangular faces that meet at a common vertex.

Answer:

Step-by-step explanation:

We know already that desk A and desk B are on the same column, since both coordinates' x factors are 7. So all we need to do now is find the difference of 2 and -8. So, we get the [very simple] equation [tex]2 - (-8) = d[/tex]. Now, when you subtract a negative, it's pretty much just adding, so we can simplify this equation to [tex]2 + 8 = d[/tex], and we all know [tex]2 + 8 = 10[/tex].

Answer:

the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die is 17/36, or approximately 0.4722

Step-by-step explanation:

To find the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die, we need to first determine the sample space of possible outcomes.

The sample space of rolling two dice is given by all possible pairs of numbers from 1 to 6, which has a total of 6 x 6 = 36 possible outcomes.

Out of these 36 possible outcomes, there are 12 outcomes where the second die shows a multiple of 3 (namely 3, 6, and 9), and 9 outcomes where the second die shows a multiple of 4 (namely 4 and 8).

However, we must note that there are two outcomes where the second die shows both a multiple of 3 and a multiple of 4, namely (3,4) and (6,4). We need to subtract these two outcomes from our total count.

Therefore, the number of outcomes where the second die shows a multiple of 3 or a multiple of 4 or both is 12 + 9 - 2 = 19.

The number of outcomes where the second die does not show a multiple of 3 or a multiple of 4 is the complement of the above count, which is 36 - 19 = 17.

Therefore, the probability of neither showing a multiple of 3 nor a multiple of 4 on the second die is 17/36, or approximately 0.4722.

Answer:

360

Step-by-step explanation:

x*60/100=216

60x=21600

x=21600/60

x=360

360 students are thee in Milton Middle School.

Number of girls in Milton Middle School = 216

Percentage of girls in Milton Middle School = 60%

From the above information we can know that 216 = 60% of Milton Middle School.

1% of students in the school = 216/60

                                                 = 3.6

100% of students in the school = 3.6 * 100

                                                      = 360 students

Total number of students in Milton Middle School = 216/60 * 100

                                                                                       = 216/6 * 10

                                                                                       = 36 * 10

                                                                                        = 360 students

To find the fourth vertex of the rectangle, we can start by drawing a diagram:

========================================

        |

        |    (2,4)

        |

--------.--------

        |

(?, ?)   |    (2,1)

        |

========================================

We know that opposite sides of a rectangle are parallel, so the fourth vertex must be located on the same horizontal line as the point (2, 1) and the same vertical line as the point (-4, 4). Therefore, the fourth vertex must be located at (-4, 1).

To find the dimensions of the rectangle, we can find the distance between the points (2, 1) and (2, 4) to get the length of one side, and the distance between the points (2, 1) and (-4, 1) to get the length of the other side.

Length = 4 - 1 = 3

Width = 2 - (-4) = 6

So the dimensions of the rectangle are 6 by 3.

To find the area of the rectangle, we can multiply the length and width together:

Area = Length x Width = 6 x 3 = 18 square units.

10 - x = 4x + 5

10 = 5x + 5

5 = 5x

x=1

Answer:

10 - x = 4x + 5

10 - 5 = 4x - x

     5  =  3x

      x = 1.6

         x = 1.6      

angle 1 =  10-1.6

            = 8.4

angle 2 = 4(1.6)+5

Step-by-step explanation:

       A polygon is a closed shape with no curved side. We see four curved sides in this shape, so this figure is not a polygon.

Step-by-step explanation:

The sample space for rolling two dice consists of 36 possible outcomes, as each of the six faces on the first die can be combined with any of the six faces on the second die.

To find the probability of showing either a prime number on the first die or a multiple of 5 on the second die, we can use the principle of inclusion-exclusion.

There are 3 prime numbers on a standard die: 2, 3, and 5. And there are two multiples of 5: 5 and 10. However, we need to be careful not to count the outcome (5,5) twice, as it satisfies both conditions.

So, the probability of showing either a prime number on the first die or a multiple of 5 on the second die is:

P(prime or multiple of 5) = P(prime) + P(multiple of 5) - P(prime and multiple of 5)

P(prime) = 3/6 = 1/2

P(multiple of 5) = 2/6 = 1/3

P(prime and multiple of 5) = 1/36

Therefore,

P(prime or multiple of 5) = 1/2 + 1/3 - 1/36

= 19/36

So the probability of showing either a prime number on the first die or a multiple of 5 on the second die is 19/36, or approximately 0.528.

Answer: Count all the sides and the answer will be 4.5+2+2+4+5.5+1.5+1+7.5, which is equal to 26.5 (I think, I didn’t use a calculator)

The perimeter of the figure shown on the coordinate plane is 56 units.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given is a figure.

Perimeter of a figure is the total length of the boundary.

We have to find the length of each of the sides and then add it to get the perimeter.

Each line on the coordinate plane represents 2 units.

Perimeter adding the sides from the bottom, we get,

Perimeter = 2 + 3 + 11 + 8 + 4 + 4 + 9 + 15

                 = 56 units

Hence the perimeter of the figure is 56 units.

Answer:

Step-by-step explanation:

1/2 = 3/6 (on time)      

1/3 = 2/6 (late)

1/6 = 1/6 (early)

3 times 2 is 6. You need the same denominators. What you do to the bottom you do to the top. So, 3x2=6 and 1x2=2. Therefore, you have 2/6. The 2 cubes can be used to show the probability of the train being late because we now know it is late 2/6 times and either early or on time 4/6 times.
