How many kids will there be ?Mr. Fulton's class has 30 students. The double number line shows the number of students that represents 40% of Mr. Fulton's class.The top number line is labeled, "Number of Students" and ranges from 12 to a question mark. The bottom number line is labeled, "Percent" and ranges from 0% to 100%.Since 40% of Mr. Fulton's class is 12 students, we can use the proportion 12/40 = x/100 to determine how many students are in the class. When we solve for x, we get x = 30.
By solving for the total number of students, we can calculate the number of students in Mr. Fulton's class. Using this equation, we can determine that the total number of students in Mr. Fulton's class is 30. Thus, there are 30 students in Mr. Fulton's class.Therefore, Mr. Fulton's class has 30 students.

According to the information, the missing number is 1,333.333 (option B).
What is the 14th partial sum of 2,000 - 1,000 + 500 - 250 + ...?To find the result of this procedure we have to take into account the following information:
The series is an alternating series with a common ratio of -1/2. According to this, we can use the formula for the sum of the first n terms of an alternating geometric series:
Sn = a(1 - r^n)/(1 - r)
where,
a = first term
r = common ratio
n = number of terms
In this case, a = 2000 and r = -1/2. Plugging these values into the formula and simplifying, we get:
S14 = 2000(1 - (-1/2)^14)/(1 - (-1/2))
= 2000(1 - 1/16384)/(3/2)
= 1333.333
According to the above, we get 1,333.333. So, the closest answer choice is (B) 1,333.333.

a = delta v over t.
m = StartFraction x subscript 2 minus x subscript 1 Over v subscript 1 - v subscript 2 EndFraction.
Answers
Answer:

Step-by-step explanation:
Acceleration is the change in velocity per unit time. It is usually represented by the letter "a". An appropriate formula is ...
\(\boxed{a=\dfrac{\Delta v}{t}}\)
The required equation for determining the acceleration from a velocity-time graph is \(a=\dfrac{\Delta v}{t}\)equation is a=delta v over t.
We know that,
Acceleration is known as the rate of change of velocity per unit time.
The velocity vs time graph is the graph plotted between the change in velocity with the change in time.

(a) From Latoya's results, compute the experimental probability of rolling a 1 or 6.
(b)Assuming that the cube is fair, compute the theoretical probability of rolling a 1 or 6.
(c)Assuming that the cube is fair, choose the statement below that is true.
A. The experimental and theoretical probabilities must always be equal.
B. As the number of rolls increases, we expect the experimental and theoretical probabilities to
become closer, though they might not be equal.
C. As the number of rolls increases, we expect the experimental and theoretical probabilities to
become farther apart.
Answers
(a) To compute the experimental probability of rolling a 1 or 6 from Latoya's results, we need to determine the number of times a 1 or 6 was rolled and divide it by the total number of rolls Latoya made.
Let's assume that Latoya rolled the dice 100 times and obtained 20 1's and 10 6's. The total number of successful outcomes (rolling a 1 or 6) is 20 + 10 = 30.
Therefore, the experimental probability of rolling a 1 or 6 is 30/100 = 0.3 or 30%.
(b) Assuming the cube is fair, the theoretical probability of rolling a 1 or 6 can be determined by considering the favorable outcomes (rolling a 1 or 6) divided by the total possible outcomes (rolling any number from 1 to 6).
Since there are two favorable outcomes (1 and 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), the theoretical probability is 2/6 = 1/3 or approximately 0.3333.
(c) The correct statement is B. As the number of rolls increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal. This is due to the law of large numbers, which states that as more trials are conducted, the experimental probability tends to converge towards the theoretical probability. However, it is not necessary for them to be exactly equal. Random variations can cause some discrepancy, but with a larger number of rolls, the experimental probability should approach the theoretical probability more closely.

Establish the initiating vertex as the current vertex.
Analyze all neighboring vertices of the current vertex and determine their respective tentative path length via current vertex. Proceed to compare it with its already assigned value; upgrade such distance if shorter than before.
Subsequent to analyzing adjacent points of the present node, designate it as 'visited'. Futuristic reference will disregard this chosen and visited vertex altogether.

Two cylinders, a and b, each started with different amounts of water. The graph shows how the height of the water changed as the volume of water increased in each cylinder. Match the graphs of a and b to Cylinders P and Q. Explain your reasoning. height in centimeters b volume in milliliters P
Answers
To match the graphs of cylinders a and b to cylinders P and Q, we need to analyze the relationship between the height of the water and the volume of water in each cylinder.
Cylinder P would correspond to graph b, while Cylinder Q would correspond to graph a.
The reasoning behind this is as follows:
Cylinder P, corresponding to graph b, shows a steeper increase in height with increasing volume. This indicates that the water level rises quickly as more volume is added, suggesting that the cylinder has a smaller cross-sectional area. Since height is directly proportional to volume for a cylinder, a smaller cross-sectional area would result in a higher rise in height for the same volume of water.
Cylinder Q, corresponding to graph a, shows a slower increase in height with increasing volume. This implies that the water level rises more gradually as more volume is added, indicating a larger cross-sectional area. A larger cross-sectional area would result in a smaller increase in height for the same volume of water.
In summary, the steeper graph b matches Cylinder P with a smaller cross-sectional area, while the gentler graph a matches Cylinder Q with a larger cross-sectional area.
