Tracking is the practice of testing students and using the results to place them in specific classes (such as remedial, advanced, college prep, etc.).
What is tracking?Tracking in mathematics has become a hot topic in many school systems. By definition, tracking means that students are separated into different levels of courses due to their. mathematical ability and prior performance.The term "tracking" refers to a strategy many secondary schools employ to classify students based on their perceived aptitude, IQ, or levels of achievement. In an effort to match the curriculum and instruction to the students' needs, they are divided into high, middle, and low tracks.Tracking is the most commonly used term for ability grouping, the practice of lumping children together according to their talents in the classroom. On the elementary level, the divisions sound harmless enough: Kids are divided into the Bluebirds and Redbirds.hence,Tracking is the practice of testing students and using the results to place them in specific classes (such as remedial, advanced, college prep, etc.).

100 POINTS!!! PLEASE HELP ME
Step-by-step explanation:
For question 30, the first choice is not necessarily true. I attached a picture of what *could* be the parallelogram.
The first choice is true ONLY if the parallelogram is a square.
The second choice is not necessarily true either. It is true ONLY if the parallelogram is a rhombus (a square is also a rhombus, just for reference)
But opposite sides of a parallelogram are always equal
So the answer to question 30 are the first and second choices.
For question 31:
remember what I said about how opposite sides of a parallelogram are always equal? Well opposite angles are also always equal.
So angle BKX = angle BWX = angle XWB = 114 degrees
Angle BKW = angle XWK (using parallel lines) = angle XWB - angle BWK = 114 - 22 = 92 degrees
Angle WBX = angle BXK (using parallel lines too) = angle WXK - angle WXB.
Consecutive angles in a parallelogram add up to 180. So angle WXK + angle XWK = 180. angle WXK = 180 - angle XWK = 180 - 114 = 66 degrees.
angle WDB + angle WBX + angle BWK = 180 because it's a triangle
angle WDB + 66 (just figured it out) + 22 (given) = 180 degrees
angle WDB = 180 - 66 - 22 = 92 degrees
I hope I didn't do anything wrong lol
but I prolly did XD
Answer:
angle WDB + angle WBX + angle BWK = 180 because it's a triangle
angle WDB + 66 + 22 (given) = 180 degrees
angle WDB = 180 - 66 - 22 = 92 degrees

62.5% fo boys plays cricket in the whole class.
what is ratio?
A mathematical comparison of two or more values or quantities is called a ratio. It can be used to compare the relative sizes or amounts of various items since it expresses the relationship between the values in terms of a proportion or a fraction.
Let the number of boys who play cricket be x
and the number of boys who play football be y
so total number of students is x+y
given the ratio that y/x=3/5
so y = 3k and x = 5k where k is a constant
so total number of student is x+y
=> 3k+5k
=> 8k
so percentage of boy who play cricket is given by

the area of the shaded region is $78$ square inches. all angles are right angles and all measurements are given in inches. what is the perimeter of the non-shaded region?
The perimeter of the non-shaded region in the figure can be calculated to be 14 inches.
Given a figure.
The middle portion of the figure is not shaded.
It is required to find the perimeter of the non-shaded region.
It is given that:
The whole area of the shaded region = 78 inches²
The area of the small square which is situated at the bottom is:
Area of small square = 2 × 4
= 8 inches²
So, the area of the rest of the shaded area = 78 - 8
= 70 inches²
Now, the area of the whole region without the small square is:
Area = 10 × (10 - 2)
= 80 inches²
So, the area of the non-shaded region = 80 - 70
= 10 inches²
The width of the non-shaded rectangle is 2 inches.
So, length = 5 inches.
So, the perimeter is:
P = 2(5 + 2)

The three seventh grade classes at Sunview Middle School collected the most boxtops for a school funderaiser, and so they won a $600 prize to share among them. Mr. Aceves' class collected 3.750 box tops, Mrs Baca's class collected 2,301, and Mr. Canyon's class collected 1,855. A. What fraction of total box tops did each class collect? B. How much money should each class receive to reflect their fraction of the total?
Answers and step-by-step explanation:
First, we add up all the totals for the box tops. This would be 3,750+2,301+1855 which totals to 7,906. Then, we take each individual box top value and divide it by 7,906 to get the fractions. For Mr. Aceves' class, the percentage is 47%, for Mrs. Baca's class, the percentage is 29% and finally for Mr. Canyon's class, the percentage is roughly 24%. This would mean that Mr. Aceves' class should get $282, Mrs. Baca's class should get roughly $174, and Mr. Canyon's class should receive $144.

The average rate of change for d(t) = 40| t - 1.25| in interval 0.5 ≤ x ≤ 1.0 is -40.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
The given function is,
d(t) = 40| t - 1.25|
And the given interval, is 0.5 ≤ x ≤ 1.0
To find the average rate of change for given function,
Use formula
Average rate of change = f(b) - f(a) / b - a
In the given question a = 0.5 and b= 1.0
d(0.5) = 40 | 0.5 - 1.25| = 40 |-0.75| = 40(1.20) = 30

a water treatment plant needs to maintain the ph of the water in the reservoir at a certain level. to monitor this, they take 2 oz. of water at 37 locations every hour, measure the ph at each of those locations, and find their average. if the ph level of the reservoir is ok, the results at each location will have varying results, with an average ph of 8.5 and a standard deviation of 0.22. if the ph level of the reservoir is ok, what is the probability that the sample average is more than 8.47? group of answer choices
The probability that the sample average is more than 8.47 is 0.4406 if the pH level of the reservoir is ok
To calculate this, we will use a standard normal distribution table and the Z-score formula.
First, we need to calculate the Z-score for the sample average of 8.47. This is done by using the Z-score formula:
Z-score = (x - mean)/standard deviation
where x is the sample average, mean is the average of all samples, and standard deviation is the standard deviation of all samples.
In this case, the Z-score is:
Z-score = (8.47 - 8.50)/0.22 = -0.14
Then, we need to look up the Z-score in a standard normal distribution table. The probability of the sample average being more than 8.47 is equal to 1 minus the Z-score probability. So, in this case, the probability of the sample average being more than 8.47 is equal to 1 - 0.5594 = 0.4406.
Therefore, the probability that the sample average is more than 8.47 is 0.4406 if the pH level of the reservoir is ok.

Maggie runs 1/4 of a mile in 1.3 minutes. Olivia runs 2/3 of a mile in 2.9 minutes. Who runs faster? How much faster per hour does the person run?
Answer:
Olivia-2.25
Step-by-step explanation:
Olivia runs faster than Maggie.
Olivia runs 2.22 miles/hour faster than Maggie.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
To compare the speeds of Maggie and Olivia, we can calculate their respective rates using the formula:
rate = distance/time
For Maggie:
distance = 1/4 mile
time = 1.3 minutes
rate = (1/4) / 1.3 = 0.1923 miles/minute
For Olivia:
distance = 2/3 mile
time = 2.9 minutes
rate = (2/3) / 2.9 = 0.2293 miles/minute
Therefore, Olivia runs faster than Maggie.
To find out how much faster Olivia runs per hour, we can convert her rate to miles per hour:
0.2293 miles/minute x 60 minutes/hour x 60 seconds/minute
= 13.758 miles/hour
Similarly, we can convert Maggie's rate to miles per hour:
0.1923 miles/minute x 60 minutes/hour x 60 seconds/minute
= 11.538 miles/hour
The difference in their speeds is:
13.758 - 11.538
= 2.22 miles/hour
So,
Olivia runs 2.22 miles/hour faster than Maggie.
Thus,
Olivia runs faster than Maggie.
Olivia runs 2.22 miles/hour faster than Maggie.
