Her data are shown in the table. She draws a line of best fit with the equation y = -6.2x + 64, where x represents the hour and y represents the temperature.
Describe the meaning of the slope and y-intercept in this context
A. 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
B. The slope applied to this situation is the temperature drops 6.2 degrees per hour The y-intercept means at hour 1, it was a temperature of 6.2 degrees
C. The slope applied to this situation is the temperature drops 64 degrees per hour. The y-intercept means at hour 0, it was a temperature of 6.4 degrees
D. The slope applied to this situation is the temperature drops 6.2 degrees per 2 hours. The y-intercept means at hour 2, it was a temperature of 64 degrees
Answers
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.
What is Slope?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.

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].

How many faces does a square pyramid not including it's base
Answers
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.

360 students are thee in Milton Middle School.
Step-by-step explanation: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

Find the probability of showing either
prime number on the first die or multiple of 5 on the second die
Answers
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.

B. n = 0.68t
C. n = 32t
D. n = 68t
PLS ANSWER!
Answers
Answer:
The percentage of earrings is 32%, which means that the remaining percentage of jewelry items that are not earrings is 100% - 32% = 68%. Therefore, the equation that represents the relationship between the number (n) of jewelry items that are not earrings and the total number (t) of jewelry items produced is: n = 0.68t So, the correct answer is B.
B) n = 0.68t.
If 32% of the jewelry items produced are earrings, then 68% of the jewelry items produced are NOT earrings. Therefore, the equation for n is n = 0.68t.

To find the area of the parallelogram formed by the points (-5, 2), (2, 0), and (4, -4), we need to first find the fourth vertex of the parallelogram. Since opposite sides of a parallelogram are parallel and have equal length, the fourth vertex can be obtained by adding the vector formed by the points (-5, 2) and (2, 0) to the point (4, -4). This gives us the fourth vertex as (11, -6).
Next, we can use the distance formula to find the lengths of the two sides of the parallelogram. The length of the side connecting (-5, 2) and (2, 0) is sqrt(45), and the length of the side connecting (2, 0) and (4, -4) is 2sqrt(5).
Finally, we can use the formula for the area of a parallelogram, which is base times height, to find the area of the parallelogram. The base of the parallelogram is the distance of sqrt(45) between (-5, 2) and (2, 0), and the height is the distance of 2sqrt(5) between (2, 0) and (4, -4). Multiplying these values together gives us an area of 42 square units, which is option C.
Four points are drawn on the coordinate plane and connected with straight lines to form a rectangle. Three of the vertices of the rectangle are located at (2, 1), (2, 4), and (-4, 4). What are the coordinates of the fourth vertex of the rectangle? What are the dimensions of the rectangle? What is the area of the rectangle?
Answers
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.
Width is 2+4
Length times width is going to get you 18 which is your final answer

Answers
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.
