There are three solutions of the equation ||2x-3|-m|=m have if m>0.
We have to estimate the number of solutions of the equation ||2x - 3| - m| = m where m > 0.
As we know in the modulus function
|x|= x if x>0
-x if x<0
0 if x=0
here given m > 0
if |2x-3|-m>0 then the modulus value will be ||2x-3|-m|= |2x-3|-m
Then, |2x - 3| - m = m
⇒|2x - 3| = m+m= 2m
⇒2x - 3 = 2m or -(2x-3)=2m
⇒2x - 3 = 2m or 2x-3=-2m
⇒2x = 3 ± 2m
⇒x = (3 ± 2m)/2
⇒x= (3 + 2m)/2 or (3 - 2m)/2
If |2x-3|-m<0 then then the modulus value will be | |2x-3|-m| = -(|2x-3|-m)
-(|2x-3|-m)=m
⇒m-|2x-3|=m
⇒-|2x-3|= m-m
⇒ |2x - 3| = 0
⇒2x = 3
⇒x = 3/2
Therefore The solution of the equation will be (3 + 2m)/2, (3 - 2m)/2, and 3/2.
Therefore there are three solutions of the equation ||2x-3|-m|=m have if m>0.

WHAT IS THE AVERAGE NUMBER OF POINTS THAT CHANGED HANDS
The average number of points will be 15 points.
How to calculate the average?It should be noted that average or mean simply means the total added values fall the data in a set which is then divided by the number of data.
Let the assumed points be 10, 12, 24, 15, 23, and 6.
In this case, the average number of points will be:
= (10 + 12 + 24 + 15 + 23 + 6)/6

How to Find the Solution to the System of Equations?The values of x and y that makes two equations equal is the solution of a system of equations.
6. 3x + 4y = 12 --> eqn. 1
y = 3 - 3/4x --> eqn. 2
Substitute y = (3 - 3/4x) into eqn. 1 to find x:
3x + 4(3 - 3/4x) = 12
3x + 12 - 3x = 12
12 = 12 [unable to solve further for x]
This means that the system of equations has no solution.
7. t = tables

3t + 5c = 62.5 --> eqn. 1
3t + 2c = 52 --> eqn. 2
Subtract
3c = 10.5
c = 3.5 [chairs]
Substitute c = 3.5 into eqn. 2

Noise levels at 5 volcanoes were measured in decibels yielding the following data: 108,133,140,129,136 1. Construct the 98% confidence interval for the mean noise level at such locations. Assume the population is approximately normal.
2. Calculate the sample standard deviation for the given sample data. 3. Find the critical value that should be used in constructing the confidence interval.
The confidence interval or the mean noise level is (108.17,150.23) and sample standard deviation is 12.52.
Given noise levels:108,133,140,129,136. and confidence level 98%.
We have to find the confidence level and the sample standard deviation of the given data.
Confidence level=98%.
n=5
Sample standard deviation=[tex]\sqrt{(x-x bar)^{2} /n-1}[/tex]
=[tex]\sqrt{626.8/4}[/tex]
=[tex]\sqrt{156.7}[/tex]
=12.52
critical t value at 98% confidence level with degree of freedom(5-1) is 3.747
Standard error= critical t*s/[tex]\sqrt{n}[/tex]
Standard error is the difference between the real values and calculated values.
=3.747*12.52/[tex]\sqrt{5}[/tex]
=46.91/2.23
=21.03
Upper confidence interval=Mean +standard error
=129.2+21.03
=150.23
Lower confidence interval=Mean - standard error
=129.2-21.03
=108.17
Hence the confidence interval is (108.17,150.23) ,sample standard deviation is 12.52 and critical t value is 3.747.

is 7 1/5•49 7/5 equivalent to 49 2/10 • 7 1/5
We can calculated each one out :
7 1/5 x 49 7/5 = 36/5 x 252 / 5 = 9072 / 25
49 2/10 x 7 1/5 = 980 / 10 x 36/5 = 35280 / 50 = 3528 / 5
or a much simpler way is that because both multiplication has 7 1/5 so we only have to compare the other terms, and since 49 7/5 is not equal to 49 2/10 these are not equal. and i didnt notice that till now.

Option D is correct.
Figures are missing in the question.
The images below shows the missing figures of question.
Solution:For congruent figures, we need the same shape, same area, and inverse direction.
Congruent figures have congruency. That seems simple enough, but congruent figures need not be turned the same way or face the same direction to be congruent.
In the case of geometric figures, line segments with the same length are congruent and angle with the same measure are congruent.
In elementary geometry the word congruent is often used as follows. The word equal is often used in place of congruent for these objects.
In this sense, two plane figures are congruent implies that their corresponding characteristics are "congruent" or "equal" including not just their corresponding sides and angles, but also their corresponding diagonals, perimeters, and areas.
The figure in option D satisfies all these conditions. Hence, Option D is correct.

Answer: a monomial has one term, binomial has 2 terms, and trinomial has 3.
Step-by-step explanation:
using a bit of greek and latin roots, we can observe that all 3 terms have the same suffix of nomial in them. From this, we know that mono means one, bino means two, and tri means 3. Fun fact, there's also polynomial (if you did or didn't know), which is multiple terms more than 3.

It is given that the rocket that will return the rock and soil samples to Earth cannot lift off if the total weight of the samples from the rovers exceeds 530 pounds.
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p). A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution. The binomial distribution is the basis for the popular binomial test of statistical significance.

Which of the expressions below are equal to 8x² + 30x + 18?
Select all that apply.
A) (4x + 3) (2x + 6)
B) 6x² + 20x + 2x² + 10x + 18
C) 2(4x² + 15x + 9)
D) 4(2x² + 7x + 4)
Answer:
A, C, and D
Step-by-step explanation:
A) (4x + 3) (2x + 6) is equal to 8x² + 30x + 18 because when you multiply two binomials, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, (4x + 3) (2x + 6) can be rewritten as (4x)(2x) + (4x)(6) + (3)(2x) + (3)(6). This can further be simplified to 8x² + 24x + 18.
C) 2(4x² + 15x + 9) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 2(4x² + 15x + 9) can be rewritten as 2(4x²) + 2(15x) + 2(9). This can further be simplified to 8x² + 30x + 18.
D) 4(2x² + 7x + 4) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 4(2x² + 7x + 4) can be rewritten as 4(2x²) + 4(7x) + 4(4). This can further be simplified to 8x² + 28x + 16.

In this vase, with a number line with two points opposite from each other on a number line, the middle of it is always going to be 0.
Therefore, both points are the same distance away from 0 just in opposite directions.
That means point Q is always going to equal the negative of point P. An example of this is if point p equals 5, point p equals -5.
This method only works when it is specifically stated that the two points are opposite from each other.
