Answer:
50000
Step-by-step explanation:
We know it increase 27% since it was last measured
100% + 27% = 127%
We have to find 1%
We take 63500 divided by 127 = 500
500 times 27 = 13500
Now we have to take 63500 and subtract by 13500 to find the previous population.
63500 - 13500 = 50000
So, the previous population is 50000

suppose sat math scores are normally distributed with a mean of 516 and a standard deviation of 115 while act math scores have a normal distribution with a mean of 22 and a standard deviation of 5. anna scored 650 on the sat math and bob scored 29 on the act math. assuming that both tests measure the same kind of ability, who did better in terms of the standardized z-score?
By assuming that both tests measure the same kind of ability, Bob did better in terms of the standardized Z-score.
We have provide a data about two major math's tests.
First Major test : SAT math score normally distributed with
Mean , μ = 516 and
Standard deviations, σ = 115
Second Major test: ACT math score normally distributed with
Mean, μ = 22
Standard deviations, σ = 5
Anna scores in SAT test 650
i.e x = 650
Using Z-Score formula,
Z = (x - μ)/σ
Z = (650 - 516)/115 = 154/115 = 1.17
Also, Bob score on ACT math test is 29 i.e x = 29
Z-Score = (x - μ)/σ
=> Z = (29 - 22)/5 = 7/5
=> Z = 1.4
Since, Z-Score for Bob's ACT math test is high as compared to Anna's SAT math test.
So, Bob did better in terms of the standardized z-score.

Please help answer this. I really need a detailed answer using Side angle side or SSS thanks!
Wrong, or incomplete answers will be reported

Step-by-step explanation:
There’s no labels so it might be hard to explain this one otherwise
-We’ll call the point at the top left with y°: A
-the bottom right point with x°: C
-the point in between them with 40°: B
-the bottom left point with the right angle: D
angle DBC = 140° because angles on a straight line sum to 180°
so x must equal 20 because the other angles in an isosceles triangle are equal and 180-140=40 and 40/2=20
90-20=70 so angle ADB=70
meaning that y must equal 70 because 70+40=110 and 180-110=70
determine the average rate of change in concentration of b from t=0 s to t=222 s.
The average rate of change in concentration of b from t=0 s to t=222 s as calculated from the data given is 0.00916M/s.
The changes happening in A can be found as ,
= 0.140 - 0.650
= -0.510 M
Time = 222 s - 0 s
= 222 s
Therefore the average rate of change of A is
= -0.510 M / 222 s = -0.00229 M/s
Since the value obtained is negative we can conclude that the rate is decreasing.
Using stoichiometry equation we can find the value of B as ,
The average rate of change of B
= 2 x 0.00229
= +0.00458 M/s
-∆[A]/∆t = +1/2∆[B]/∆t

a linear function has an x-intercept of −8 − 8 and a y-intercept of 4 4 . which of these is an equation of the linear function?
A linear function can be represented by an equation of the form y = mx + b, where m is the slope of the function and b is the y-intercept. The x-intercept is the point where the graph of the function intersects the x-axis, and the y-intercept is the point where the graph intersects the y-axis.
Given that the x-intercept of the linear function is −8 and the y-intercept is 4, an equation of the function can be written as:
y = mx + b
Substituting the values of the x-intercept and the y-intercept into this equation, we get:
y = m(-8) + 4
Since the y-intercept is 4, this equation can be rewritten as:
y = 4 + mx
This equation represents a linear function with a y-intercept of 4 and a slope of m.
Therefore, an equation of the linear function with an x-intercept of −8 and a y-intercept of 4 is y = 4 + mx.

The standard error of the sample mean is approximately 8.9 pounds.
What is standard error of the sample mean?
Simple division of the standard deviation by the square root of the sample size yields the SEM. By evaluating the sample-to-sample variability of the sample means, standard error determines the accuracy of a sample mean.
To find the standard error of the sample mean, we need to first find the sample mean weight of the students. To do this, we add up the weights of all the students and divide by the number of students:
(128 + 193 + 166 + 147 + 202 + 183 + 181 + 158) / 8 = 171.5
Next, we need to find the variance of the sample. The variance is a measure of the spread of the data around the mean, and is calculated as follows:
[tex]variance = ((weight - mean)^2) / (n-1)[/tex]
where weight is the weight of each student, mean is the sample mean weight, and n is the number of students.
Plugging in the values from our data, we get:
variance = (128 - 171.5)^2 + (193 - 171.5)^2 + (166 - 171.5)^2 + (147 - 171.5)^2 + (202 - 171.5)^2 + (183 - 171.5)^2 + (181 - 171.5)^2 + (158 - 171.5)^2 / 7
= 1096.5
Finally, we can find the standard error of the sample mean by taking the square root of the variance and dividing by the square root of the number of students:
[tex]standard\ error = \sqrt{(variance / n)} \\\\= \sqrt{1096.5 / 8 )\\\\=8.9[/tex]
So, The standard error of the sample mean is approximately 8.9 pounds.

Is discontinuous function a function?
Yes, a discontinuous function is a function that is not continuous.
A function can have an asymptote if it approaches a horizontal or vertical line but never touches it. There are several types of functions that can have asymptotes, including rational functions, exponential functions, and logarithmic functions.
A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.
A function is continuous if its graph can be drawn without lifting the pencil from the paper, or if the function's values remain "close" to one another as the input values change. A discontinuous function, on the other hand, has "breaks" or "jumps" in its graph, indicating that the function's values become "far" from one another as the input values change. An example of a discontinuous function is the absolute value function.

Answer:
... centroid, or center of gravity.
Step-by-step explanation:
The point of concurrency of the medians of a triangle is always inside the triangle and is called the ______.
MediansA median joins a vertex of a triangle with the midpoint of the opposite segment. It is a line segment that lies entirely within the triangle. Hence any two medians will meet at a point that is within the triangle.
The point of concurrency of medians is called the "centroid." If the triangle has uniform areal density, the centroid will be the center of gravity, the point at which the triangle could be balanced.
The centroid divides each median into parts in the ratio 1:2, where the longer part is the segment to the vertex, and the shorter is the segment to the midpoint of the side.
Can a 13 year old be in 7th grade?
If the age requirements for academic progressions set by a school is satisfied, than yes it is possible for a 13 year old to be in 7th grade.
What is the perfect age for a child to start schooling?The age at which a child is ready to start schooling can vary depending on a number of factors, including the child's physical, social, and emotional development. In general, children who are at least 5 years old and are able to meet certain developmental milestones are typically ready to start school.
Why academic skill is more important than age before grading up?Because academic skills are directly tied to a pupil's capacity for academic success, they are sometimes seen as being more significant than age when deciding whether a student is prepared to proceed to a higher grade level. Age is not always a reliable indicator of a student's intellectual aptitude or preparation for a higher grade level. Even if they are younger than their peers, some children may be farther along in their studies and possess the abilities and knowledge required to succeed in a higher grade. Even if they are older than their friends, some kids may be falling behind in their academics and not yet ready to advance to a higher grade.
Depending on the school's age requirements and the student's academic standing, a 13-year-old may be in the 7th grade. A kid who is 13 years old might be in seventh grade since in many educational systems, pupils in this grade are between the ages of 12 and 13. It is usually recommended to verify with the school to clarify their age requirements because they might differ from one school system to another. The intellectual ability of a student may also play a role in establishing what grade they are in addition to their age.
